Abstract: COVID-19 has led to an unprecedented disruption of normal social relationships and activities, which are so important during the teen years and young adulthood, and to education and economic activity worldwide. The impact of this on young people’s mental health and future prospects may affect their need for support and services, and the speed of the nation’s social recovery afterwards. This study focused on the unique challenges facing young people at different points during adolescent development, which spans from the onset of puberty until the mid-twenties. Although this is an immensely challenging time and there is a potential risk for long term trauma, adolescence can be a period of opportunity, where the teenagers’ brain enjoys greater capacity for change. Hence, the focus on young people is key for designing age-specific interventions and public policies, which can offer new strategies for instilling resilience, emotional regulation, and self-control. In fact, adolescents might be assisted to not only cope, but excel, in spite of the challenges imposed by this pandemic. Our work will feed into the larger societal response that utilizes the discoveries about adolescence in the way we raise, teach, and treat young people during this time of crisis. Wave 1 data has already been collected from 2,002 young people aged 13-24, measuring their mental health (anxiety, depression, trauma), family functioning, social networks, and resilience, and social risk-taking at the time of the pandemic. Here we present a preliminary report of our findings, (Report 1). Data collected 21/4/20- 29/4/20 - a month after the lockdown started).

Abstract: Successful delivery of a COVID-19 vaccine may be undermined if populations are not receptive to inoculation as a primary public health strategy for combatting the virus. We gathered nationally representative data from the general adult populations of Ireland (N=1,041) and the United Kingdom (UK N=2,025) to determine rates of hesitancy and resistance to a future COVID-19 vaccine and to identify and psychologically profile vaccine hesitant/resistant in iduals in a way that might aid future public health messaging. Vaccine hesitancy was evident for 26% and 25% of Irish and UK s les, respectively, while vaccine resistance was evident for 9% and 6%, respectively. Vaccine hesitant/resistant respondents in Ireland and the UK differed in relation to a number of sociodemographic, political, and health-related variables, but were similar across a broad array of psychological constructs. In both populations, those who were resistant to a COVID-19 vaccine were less likely to obtain information about the pandemic from traditional and authoritative sources and had similar levels of mistrust in these sources. The current findings may help public health officials to more effectively target vaccine hesitant and resistant in iduals, develop effective communication strategies that take into account their specific psychological dispositions, and leverage dissemination channels that can successfully reach these in iduals.

Abstract: A cross-sectional study was conducted with 605 practitioners of Brazilian Jiu Jitsu (BJJ) to test hypothesis that high arousal rituals promote social cohesion, primarily through identity fusion bonds. BJJ promotion rituals are rare, highly emotional ritual events that often feature gruelling belt whipping gauntlets. We used the variation in such experiences to examine whether more gruelling rituals were associated with more social cohesion and progroup behaviour. We found no differences between those who had undergone belt-whipping and those who had not and no evidence of a correlation between pain and social cohesion. However, across the full s le we found that positive, but not negative, experiences of promotional rituals were associated with identity fusion bonds and that this mediated progroup action. These findings provide new evidence concerning the social functions of collective rituals and demonstrate the importance of addressing the potentially erging subjective experiences of painful rituals.

Abstract: The primary aim of this study was to estimate the rate of face mask use during the COVID-19 pandemic in a representative UK adult population s le and assess its association with demographic, health, and mental health variables. The rate of face mask wearing was 16.7% and was associated with being younger, male, living in an urban environment, having existing health problems, increased perceived risk of COVID-19, depression, traumatic stress, and COVID-19 related anxiety. The number of people prepared to wear face masks needs to increase significantly if the UK government recommends their use.

Abstract: When the availability of rewards change unpredictably (i.e., are volatile), exploration may be a critical behaviour for tracking such changes. With the expectation that adolescents (aged 16-17 N=91) would be more adept than adults (24+ N=90) at using exploration to adjust to volatility, we employed a foraging task together with a well-validated computational model to characterise the mechanisms of exploration in volatile environments. We also predicted that anxiety would impair computational mechanisms that facilitate adjustment to environmental volatility. Like the optimal foraging agent, participants exhibited more stochastic (i.e., variable) decision-making in the volatile environment, meaning they more often trialled different responses that facilitated discovery of changes to the environment. Further, adolescents exhibited more stochastic choices than adults, though anxiety impaired the ability to adjust stochasticity between environments in both age groups. Stochasticity may act as a strategy to adapt explore/exploit choices to environmental volatility and might explain increased novelty-seeking during adolescence.

Abstract: Delusional beliefs are seen in association with a number of neuropathological conditions, including schizophrenia, dementia, and traumatic brain injury. A key distinction exists between polythematic delusion (here the patient exhibits delusional beliefs about a variety of topics that are unrelated to each other) and monothematic delusion (here the patient exhibits just a single delusional belief or else a small set of delusional beliefs that are all related to a single theme). A great deal of recent research has focused on identifying and investigating various different forms of monothematic delusion. We discuss a general theoretical approach to the understanding of monothematic delusions—a two-factor approach according to which understanding the nature and genesis of any kind of monothematic delusion involves seeking answers to two questions. The first question is, what brought the delusional idea to mind in the first place? The second question is, why is this idea accepted as true and adopted as a belief when the belief is typically bizarre and when so much evidence against its truth is available to the patient? We discuss in detail six different kinds of monothematic delusion, showing for each how neuropsychological considerations allow a first factor (responsible for the content of the belief) and a second factor (responsible for the failure to reject the belief) to be plausibly identified. Five difficulties confronting this two-factor account of monothematic delusion are then identified, and attempts are made to address each one.

Abstract: Background: The current study argues that population prevalence estimates for mental health disorders, or changes in mean scores over time, may not adequately reflect the heterogeneity in mental health response to the COVID-19 pandemic within the population.Methods: The COVID-19 Psychological Research Consortium (C19PRC) Study is a longitudinal, nationally representative, online survey of UK adults. The current study analysed data from its first three waves of data collection: Wave 1 (March 2020, N=2025), Wave 2 (April 2020, N=1406) and Wave 3 (July 2020, N=1166). Anxiety-depression was measured using the Patient Health Questionnaire Anxiety and Depression Scale (a composite measure of the PHQ-9 and GAD-7) and COVID-19 related PTSD with the International Trauma Questionnaire. Changes in mental health outcomes were modelled across the three waves. Latent class growth analysis was used to identify subgroups of in iduals with different trajectories of change in anxiety-depression and COVID-19 PTSD. Latent class membership was regressed on baseline characteristics.Results: Overall prevalence of anxiety-depression remained stable, while COVID-19 PTSD reduced between Waves 2 and 3. Heterogeneity in mental health response was found, and hypothesised classes reflecting (i) stability, (ii) improvement, and (iii) deterioration in mental health were identified. Psychological factors were most likely to differentiate the improving, deteriorating and high-stable classes from the low-stable mental health trajectories. Conclusions: A low-stable profile characterised by little-to-no psychological distress (‘resilient’ class) was the most common trajectory for both anxiety-depression and COVID-19 PTSD. Monitoring these trajectories is necessary moving forward, in particular for the ~30% of in iduals with increasing anxiety-depression levels.

Abstract: In countries such as Britain and the US, court witnesses must declare they will provide truthful evidence and are often compelled to publicly choose between religious (“oath”) and secular (“affirmation”) versions of this declaration. Might defendants who opt to swear an oath enjoy more favourable outcomes than those who choose to affirm? Two preliminary, pre‐registered survey studies using minimal vignettes (Study 1, N = 443 Study 2, N = 913) indicated that people associate choice of the oath with credible testimony and that participants, especially religious participants, discriminate against defendants who affirm. In a third, Registered Report study (Study 3, N = 1821), we used a more elaborate audiovisual mock trial paradigm to better estimate the real‐world influence of declaration choice. Participants were asked to render a verdict for a defendant who either swore or affirmed, and were themselves required to swear or affirm that they would try the defendant in good faith. Overall, the defendant was not considered guiltier when affirming rather than swearing, nor did mock‐juror belief in God moderate this effect. However, jurors who themselves swore an oath did discriminate against the affirming defendant. Exploratory analyses suggest this effect may be driven by authoritarianism, perhaps because high‐authoritarian jurors consider the oath the traditional (and therefore correct) declaration to choose. We discuss the real‐world implications of these findings and conclude the religious oath is an antiquated legal ritual that needs reform.

Abstract: It has been proposed that delusional beliefs are attempts to explain anomalous experiences. Why, then, do anomalous experiences induce delusions in some people but not in others? One possibility is that people with delusions have reasoning biases that result in them failing to reject implausible candidate explanations for anomalous experiences. We examine this hypothesis by studying paranormal interpretations of anomalous experiences. We examined whether analytic cognitive style (i.e. the willingness or disposition to critically evaluate outputs from intuitive processing and engage in effortful analytic processing) predicted anomalous experiences and paranormal explanations for these experiences after controlling for demographic variables and cognitive ability. Analytic cognitive style predicted paranormal explanations for anomalous experiences, but not the anomalous experiences themselves. We did not study clinical delusions. Our attempts to control for cognitive ability may have been inadequate. Our s le was predominantly students. Limited analytic cognitive style might contribute to the interpretation of anomalous experiences in terms of delusional beliefs.

Abstract: The COVID-19 pandemic has taken a significant toll on the global population, but biotechnology has a big role to play in arresting the spread of the virus. However, the adoption of biotechnologies may be held back by cognitive biases. In particular, omission bias – the observation that people are more sensitive to the negative outcomes of acting than to those of failing to act – has been suggested to influence vaccination decision making. Omission bias might also underpin attitudes towards newer biotechnologies. In this study, we explored the role of omission bias in vaccination, gene editing, and nanotechnology decision-making using a US s le (N = 613). We examined participant’s risk choices across these three biotechnologies, focussing on the point at which they would use the respective biotechnology to treat a fictional illness (COVID-23). Although our findings are nuanced, overall we observed evidence consistent with an omission bias across all three biotechnologies.

Abstract: Research has demonstrated that situational factors such as perceived threats to the social order activate latent authoritarianism. The deadly COVID-19 pandemic presents a rare opportunity to test whether existential threat stemming from an indiscriminate virus moderates the relationship between authoritarianism and political attitudes toward the nation and outgroups. Using data from two large nationally representative s les of adults in the United Kingdom (N = 2,025) and Republic of Ireland (N = 1,041) collected during the initial phases of strict lockdown measures in both countries, we find that the associations between right-wing authoritarianism and 1) nationalism and 2) anti- immigrant attitudes are conditional on levels of perceived threat. As anxiety about the COVID-19 pandemic increases, so too does the effect of right-wing authoritarianism on those political outcomes. Thus, it appears that existential threats to humanity from the COVID-19 pandemic moderate expressions of authoritarianism in society.

Abstract: Over-purchasing and hoarding of necessities is a common response to crises, especially in developed economies where there is normally an expectation of plentiful supply. This behaviour was observed internationally early on in the COVID-19 pandemic. In the absence of actual scarcity, this behaviour can be described as ‘panic buying’ and can lead to temporary shortages. However, there have been few psychological studies of this phenomenon. We propose a psychological model of over-purchasing informed by animal foraging theory and make predictions about variables that predict over-purchasing by either exacerbating or mitigating the anticipation of future scarcity. These variables include additional scarcity cues (e.g. loss of income), distress (e.g. depression), psychological factors that draw attention to these cues (e.g. neuroticism) or to reassuring messages (eg. analytical reasoning) or which facilitate over-purchasing (e.g. income).We tested our model in parallel nationally representative internet surveys of the adult general population conducted in the United Kingdom (UK: N = 2025) and the Republic of Ireland (RoI: N = 1041) 52 and 31 days after the first confirmed cases of COVID-19 were detected in the UK and RoI, respectively.About three quarters of participants reported no or very little over-purchasing. More over-purchasing in RoI may have reflected different government messaging or historical factors. When over-purchasing occurred, it was observed across a wide range of product categories and was accounted for by a single latent factor. It was positively predicted by household income, the presence of children at home, psychological distress (depression, death anxiety), threat sensitivity (right wing authoritarianism) and mistrust of others (paranoia). Analytic reasoning ability had an inhibitory effect. Predictor variables accounted for 36% and 34% of the variance in over-purchasing in the UK and RoI respectively. With some caveats, the data supported our model and point to strategies to mitigate over-purchasing in future crises.

Abstract: The present study was designed to replicate and extend the findings of Bentall and Swarbrick (2003). It was hypothesised that patients with a history of persecutory delusions would display higher need for closure and a more extreme jumping to conclusions bias than healthy control participants. Twenty-two patients with a history of persecutory delusions and nineteen healthy control participants were administered a probabilistic reasoning task, along with self-report measures of depression and need for closure. The clinical group scored higher on need for closure than the controls, but showed no greater tendency to jump to conclusions. No relationship was found between need for closure and a jumping to conclusions bias. The results confirm an association between persecutory delusions and need for closure, yet suggest that persecutory delusions in an outpatient s le can be seen in the absence of a jumping to conclusions bias.

Abstract: Explanations of science denial rooted in in idual cognition tend to focus on general trait-like factors such as cognitive style, conspiracist ideation or delusional ideation. However, we argue that this focus typically glosses over the concrete, mechanistic elements of belief formation, such as hypothesis generation, data gathering, or hypothesis evaluation. We show, empirically, that such elements predict variance in science denial not accounted for by cognitive style, even after accounting for social factors such as political ideology. We conclude that a cognitive account of science denial would benefit from the study of complex (i.e., open-ended, multi-stage) problem solving that incorporates these mechanistic elements.

Abstract: A cluster of persistent and contentious questions in the scientific study of religion concern when and why so-called “moralistic traditions” developed and how they have shaped human relationships. Is there an association between moralistic gods and the size and/or complexity of the society that might worship them? How cross-culturally ubiquitous are such traditions? Are people more willing to engage in cooperative behavior when they believe their god cares about morality? This chapter focuses on how these questions have arisen and how generations of researchers have struggled to address them. We first briefly examine the intellectual history of the problem, pointing to some of the troubling aspects of early observations of traditional societies and subsequent anthropological positions. We then address how early observations of small-scale peoples have populated cross-cultural resources that have informed and driven contemporary empirical projects. We finish by pointing to ways in which we might go about ensuring that the conversation continues with clarity and consistency.

Abstract: We show that Kurzban et al.'s approach illuminates the relationship between religion and self-control. Whereas resource-depletion theorists suggest religion replenishes self-control resources (“strength”), we submit that religious cues make people feel observed, giving them “reason” to persevere, and we describe an experiment that supports our interpretation. Finally, we question the claim that subjective fatigue is a signal to redeploy resources.

Abstract: Delusions are pathological beliefs, often with bizarre content. They feature in neurological disorders and in psychoses associated with psychiatric disorders (e.g., schizophrenia). In this chapter we review two apparently opposing ways that the research literature characterizes delusions. While delusions are often defined as beliefs that are rigid and unaffected by evidence, they are also frequently conceptualized as beliefs that are unduly swayed by minimal, insufficient evidence. We review empirical studies and theory from psychology, neuroscience and computational psychiatry which embody this contrast. Prevailing perspectives, we show, frame belief formation as a process of integrating new evidence into existing beliefs. This view tends to sculpt hypotheses about delusions (and other psychotic symptoms such as hallucinations) into two types. First, relevant evidence fails to affect prior beliefs, which are too entrenched. Second, evidence overly dominates prior beliefs, which have too weak an influence. This paradox, we argue, calls for a profound rethinking of these perplexing and distressing symptoms.

Abstract: Von Hippel & Trivers (VH& T) propose that self-deception has evolved to facilitate the deception of others. However, they ignore the subjective moral costs of deception and the crucial issue of credibility in self-deceptive speech. A self-signaling interpretation can account for the ritualistic quality of some self-deceptive affirmations and for the often-noted gap between what self-deceivers say and what they truly believe.

Abstract: A successful response to the COVID‐19 pandemic requires achieving high levels of vaccine uptake. We tested whether directly contrasting the high efficacy of COVID‐19 vaccines with the lower efficacy of the annual flu vaccine would increase intentions to take a COVID‐19 vaccine. A pre‐registered online study of 481 participants compared four information conditions: (1) no information (2) COVID‐19 Vaccine Information Only and COVID‐19 Vaccine Information combined with flu vaccine information suggesting either (3) 60% efficacy or (4) 40% efficacy we measured COVID‐19 and flu vaccine intentions along with several other vaccine‐related variables. The Prolific platform was used to recruit 481 UK participants (64% female aged between 18 and 85 years) who had been pre‐screened to have intermediate levels of vaccine hesitancy. After reading a short text (~200 words) about COVID‐19 vaccines, participants were asked about their vaccination intentions. Providing information about the safety and efficacy of the new COVID‐19 vaccines resulted in vaccination intentions that were, on average, 0.39 standard deviations ( SDs ) higher than those in the no information condition providing the same COVID vaccine efficacy information in the context of information about flu vaccine efficacy resulted in a further significant increase in vaccination intentions that were 0.68 SD higher than those in the no information condition. This positive contrast effect for the COVID‐19 vaccine was not associated with reduced flu vaccine intentions. Vaccination intentions can be strengthened through a simple messaging intervention that utilizes context effects to increase perceived response efficacy.

Abstract: Objectives: The COVID-19 Psychological Research Consortium (C19PRC) Study aims to assess the impact of the COVID-19 pandemic in the adult population in multiple countries. This paper describes the execution of the third wave of the UK survey (the ‘parent’ strand of the Consortium) during July-August 2020. Methods: Adults (N=2025) who previously participated in the baseline and/or the first follow-up surveys were reinvited to participate in this survey, which assessed: (1) COVID-19 related knowledge, attitudes, and behaviours (2) the occurrence of common mental health disorders as well as the role of (3) psychological factors and (4) social and political attitudes, in influencing the public’s response to the pandemic. Weights were calculated using a survey raking algorithm to ensure that the cross-sectional s le is nationally representative in terms of gender, age, household income, household composition, and urbanicity. Results: 1166 adults (57.6% of baseline participants) were successfully recontacted and provided full interviews at Wave 3. As expected, the raking procedure successfully re-balanced the cross-sectional s le to within 1% of population estimates across the selected socio-demographic characteristics. Conclusion: This paper outlines the growing strength of the C19PRC Study data to facilitate and stimulate interdisciplinary research addressing important public health questions relating to the COVID-19 pandemic.

Abstract: There is widespread agreement that delusions in clinical populations and delusion-like beliefs in the general population are, in part, caused by cognitive biases. Much of the evidence comes from two influential tasks: the Beads Task and the Bias Against Disconfirmatory Evidence (BADE) Task. However, research using these tasks has been h ered by conceptual and empirical inconsistencies. In an online study, we examined relationships between delusion-like beliefs in the general population and cognitive biases associated with these tasks. Our study had four key strengths: a new animated Beads Task designed to reduce task miscomprehension, several data-quality checks to identify careless responders, a large s le (n = 1,002), and a pre-registered analysis plan. When analyzing the full s le, our results replicated classic relationships between cognitive biases and delusion-like beliefs. However, when we removed 82 careless participants from the analyses (8.2% of the s le) we found that many of these relationships were severely diminished and, in some cases, eliminated outright. These results suggest that some (but not all) seemingly well-established relationships between cognitive biases and delusion-like beliefs might be artifacts of careless responding.

Abstract: The commentaries raise a host of challenging issues and reflect a broad range of views. Some commentators doubt that there is any convincing evidence for adaptive misbelief, and remain (in our view, unduly) wedded to our “default presumption” that misbelief is maladaptive. Others think that the evidence for adaptive misbelief is so obvious, and so widespread, that the label “default presumption” is disingenuous. We try to chart a careful course between these opposing perspectives.

Abstract: Following the 2016 EU Referendum on Britain’s membership of the European Union, many people described themselves as ‘Leavers’ or ‘Remainers’. Here, we examine the emotional responses associated with Brexit identities using survey data collected from two nationally representative s les of the British public in 2019 (N = 638) and 2021 (N = 2,058). Confirmatory factor analysis indicated that many in both s les had coherent Leave or Remain identities. Remain and, to a lesser extent, Leave identities (regardless of how people actually voted in the referendum) predicted distress about Brexit-related events and clinical symptoms of depression and anxiety at both time points. Structural equation models suggested that the effect of identities on symptoms was largely mediated by distress about Brexit-related events. We demonstrate a lasting impact of Brexit on the mental health of UK citizens and that the formation of novel political identities has been more important in this process than voting behaviour.

Abstract: That delusional and delusion-prone in iduals ‘jump to conclusions’ is one of the most robust and important findings in the literature on delusions. However, although the notion of ‘jumping to conclusions’ (JTC) implies gathering insufficient evidence and reaching premature decisions, previous studies have not investigated whether the evidence gathering of delusion-prone in iduals is, in fact, suboptimal. The standard JTC effect is a relative effect but using relative comparisons to substantiate absolute claims is problematic. In this study we investigated whether delusion-prone participants jump to conclusions in both a relative and an absolute sense. Healthy participants ( n = 112) completed an incentivized probabilistic reasoning task in which correct decisions were rewarded and additional information could be requested for a small price. This combination of rewards and costs generated optimal decision points. Participants also completed measures of delusion proneness, intelligence and risk aversion. Replicating the standard relative finding, we found that delusion proneness significantly predicted task decisions, such that the more delusion prone the participants were, the earlier they decided. This finding was robust when accounting for the effects of risk aversion and intelligence. Importantly, high-delusion-prone participants also decided in advance of an objective rational optimum, gathering fewer data than would have maximized their expected payoff. Surprisingly, we found that even low-delusion-prone participants jumped to conclusions in this absolute sense. Our findings support and clarify the claim that delusion formation is associated with a tendency to ‘jump to conclusions’. In short, most people jump to conclusions, but more delusion-prone in iduals ‘jump further’.

Abstract: We investigated whether the attractive facial traits of averageness and symmetry signal health, examining two aspects of signalling: whether these traits are perceived as healthy, and whether they provide accurate health information. In Study 1, we used morphing techniques to alter the averageness and symmetry of in idual faces. Increases in both traits increased perceived health, and perceived health correlated negatively with rated distinctiveness (a converse measure of averageness) and positively with rated symmetry of the images. In Study 2, we examined whether these traits signal real, as well as perceived, health, in a s le of in iduals for whom health scores, based on detailed medical records, were available. Perceived health correlated negatively with distinctiveness and asymmetry, replicating Study 1. Facial distinctiveness ratings of 17-year-olds were associated with poor childhood health in males, and poor current and adolescent health in females, although the last association was only marginally significant. Facial asymmetry of 17-year-olds was not associated with actual health. We discuss the implications of these results for a good genes account of facial preferences.

Abstract: This study aimed to estimate the association between anxiety associated with COVID-19 and somatic symptoms, using data from a large, representative s le (N=2025) of the UK adult population. Results showed that moderate to high levels of anxiety associated with COVID-19 were significantly associated with general somatic symptoms, and in particular with gastrointestinal and fatigue symptoms. This pattern of associations remained significant after controlling for generalised anxiety disorder, pre-existing health problems, age, gender and income. This is the first evidence that anxiety associated with COVID-19 makes a unique contribution to somatisation, above and beyond the effect of generalised anxiety disorder.

Abstract: Objectives: This paper outlines fieldwork procedures for Wave 4 of the COVID-19 Psychological Research Consortium (C19PRC) Study in the UK during November-December 2020. Methods: Respondents provided data on socio-political attitudes, beliefs, and behaviours, and mental health disorders (anxiety, depression, and posttraumatic stress). In Phase 1, adults (N=2878) were reinvited to participate. At Phase 2, new recruitment: (i) replenished the longitudinal strand to account for attrition and (ii) overs led from the devolved UK nations to facilitate robust between-country analyses for core study outcomes. Weights were calculated using a survey raking algorithm to ensure the longitudinal panel was representative of the baseline s le characteristics. Results: In Phase 1, 1796 adults were successfully recontacted and provided full interviews at Wave 4 (62.4% retention rate). In Phase 2, 292 new respondents were recruited to replenish the panel, as well as 1779 adults from Wales, Scotland, and Northern Ireland, who were representative of the socio-political composition of the adult populations in these nations. The raking procedure successfully re-balanced the longitudinal panel to within 1% of population estimates for selected socio-demographic characteristics. Conclusion: The C19PRC Study offers a unique opportunity to facilitate and stimulate interdisciplinary research addressing important public health questions relating to the COVID-19 pandemic.

Abstract: This paper investigates a type of optimal stopping problem where options are presented in sequence and, once an option has been rejected, it is impossible to go back to it. With previous research finding mixed results of unders ling and overs ling biases on these kinds of optimal stopping tasks, the question remaining is what causes people to s le too much or too little compared to models of optimality? In two pilot studies and a main study, we explored task features that could lead to over- versus unders ling on number-based tasks. We found that, regardless of task features, there were no significant differences in human s ling rate across conditions. Nevertheless, we observed differences in s ling biases across conditions due to varying s ling rates of the optimal model. Our optimal model, like most models used for this type of optimal stopping problem, requires that researchers specify the mean and variance of a theoretical distribution, from which the options are generated. We show that different ways of specifying this generating distribution can lead to different model s ling rates, and consequently, differences in s ling biases. This highlights that a correct specification of the generating distribution is critical when investigating s ling biases on optimal stopping tasks.

Abstract: Objective: The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) are self-report measures of major depressive disorder and generalised anxiety disorder. The primary aim of this study was to test for differential item functioning (DIF) on the PHQ-9 and GAD-7 items based on age, sex (males and females), and country.Method (or Design): Data from nationally representative surveys in UK, Ireland, Spain, and Italy (combined N = 6, 040) were used to fit confirmatory factor analytic and multiple-indictor multiple-causes models.Results: Spain and Italy had higher latent variable means than the UK and Ireland for both anxiety and depression, but there was no evidence for differential items functioning.Conclusions: The PHQ-9 and GAD-7 scores were found to be unidimensional, reliable, and largely free of DIF in data from four large nationally representative s les of the general population in the UK, Ireland, Italy and Spain.

Abstract: An influential model of persecutory delusions put forward by Bentall and colleagues hypothesizes that persecutory-deluded patients avoid the activation of negative self-beliefs by making externalising, personalising attributions for negative events. The first study reported here used a new instrument for the measurement of persecutory ideation, the Paranoid, Persecutory and Delusion-Proneness Questionnaire, to investigate whether attributional biases are associated with subclinical persecutory ideation. The second study extended this investigation by re-examining associations between attributional biases and persecutory delusions. Both studies used the Internal, Personal and Situational Attributions Questionnaire to measure attributional style. No evidence was found for a connection between attributional biases and subclinical persecutory ideation. Furthermore, there was no support for an association between persecutory delusions and an externalising bias, and only marginal support for the hypothesized relationship between persecutory delusions and a personalising bias. These results suggest that the putative link between persecutory ideation and attributional biases only manifests (if at all) when persecutory ideation is of delusional intensity, and that it is confined to a personalising bias.

Abstract: Background: Two theoretical perspectives have been proffered to explain changes in alcohol use during the pandemic: the ‘affordability-availability’ mechanism (i.e., drinking decreases due to changes in physical availability and/or reduced disposable income) and the ‘psychological-coping’ mechanism (i.e., drinking increases as adults attempt to cope with pandemic-related distress). Methods: We tested these alternative perspectives via longitudinal analyses of the COVID-19 Psychological Consortium (C19PRC) Study data (spanning three timepoint during March to July 2020). Respondents provided data on psychological measures (e.g., anxiety, depression, posttraumatic stress, paranoia, extraversion, neuroticism, death anxiety, COVID-19 anxiety, intolerance of uncertainty, resilience), changes in socio-economic circumstances (e.g., income loss, reduced working hours), drinking motives, solitary drinking, and ‘at-risk’ drinking (assessed using a modified version of the AUDIT-C). Structural equation modelling was used to determine (i) whether ‘at-risk’ drinking during the pandemic differed from that recalled before the pandemic, (ii) dimensions of drinking motives and the psychosocial correlates of these dimensions, (iii) if increased alcohol consumption was predicted by drinking motives, solitary drinking, and socio-economic changes. Results: The proportion of adults who recalled engaging in ‘at-risk’ drinking decreased significantly from 35.9% pre-pandemic to 32.0% during the pandemic. Drinking to cope was uniquely predicted by experiences of anxiety and/or depression and low resilience levels. Income loss or reduced working hours were not associated with coping, social enhancement, or conformity drinking motives, nor changes in drinking during lockdown. Conclusions: In the earliest stage of the pandemic, psychological-coping mechanisms may have been a stronger driver to changes in adults’ alcohol use than ‘affordability-availability’ alone.

Abstract: The term prosocial has often been taken to mean nice or neighbourly , but many acts that further in-group interests are hostile and aggressive towards out-groups. According to Norenzayan et al., religion's ability to foster social cohesion within religious groups has been a key factor in the human transition to complex societies. But what are the prospects for nonparochial “religious prosociality”?

Abstract: Parrott and Koralus argue that a particular cognitive factor--"impaired endogenous question raising"--offers a parsimonious account of three delusion-related phenomena: (1) the development of the Capgras delusion (2) evidence that patients with schizophrenia outperform healthy control participants on a conditional reasoning task and (3) evidence that deluded in iduals "jump to conclusions". In this response, I assess these claims, and raise my own questions about the "erotetic" theory of delusional thinking.

Abstract: At the centenary of research on anosognosia, the time seems ripe to supplement work in anosognosic patients with empirical studies on nosognosia in healthy participants. To this end, we adopted a signal detection framework to investigate the lateralized recognition of illness words--an operational measure of nosognosia--in healthy participants. As positively biased reports about one's current health status (anosognosia) and future health status (unrealistic optimism) have both been associated with deficient right hemispheric functioning, and conversely with undisturbed left hemispheric functioning, we hypothesised that more optimistic participants would adopt a more conservative response criterion, and/or display less sensitivity, when identifying illnesses in our nosognosia task especially harmful illnesses presented to the left hemisphere via the right visual field. Thirty-two healthy right-handed men estimated their own relative risk of contracting a series of illnesses in the future, and then completed a novel computer task assessing their recognition of illness names presented to the left or right visual field. To check that effects were specific to the recognition of illness (rather than reflecting recognition of lexical items per se), we also administered a standard lateralized lexical decision task. Highly optimistic participants tended to be more conservative in detecting illnesses, especially harmful illnesses presented to the right visual field. Contrary to expectation, they were also more sensitive to illness names in this half-field. We suggest that, in evolutionary terms, unrealistic optimism may be an adaptive trait that combines a high perceptual sensitivity to threat with a high threshold for acknowledging its presence. The signal detection approach to nosognosia developed here may open up new avenues for the understanding of anosognosia in neurological patients.

Abstract: Vaccines are a powerful and relatively safe tool to protect against a range of serious diseases. Nonetheless, a sizeable minority of people express ‘vaccination hesitancy’. Accordingly, understanding the bases of this hesitancy represents a significant public health challenge. In the present study we sought to examine the role of Big Five personality traits and general intelligence as predictors of vaccination hesitancy, across two vaccination types, in a large (N= 9667) s le of UK adults drawn from the Understanding Society longitudinal household study. We found that lower general intelligence was associated with COVID-19 and seasonal flu vaccination hesitancy, and lower neuroticism was associated with COVID-19 vaccination hesitancy. Although the self-reported reasons for being vaccine hesitant indicated a range of factors were important to people, lower general intelligence was associated with virtually all of these reasons. In contrast, Big 5 personality traits showed more nuanced patterns of association. These findings provide important insights into vaccination hesitancy and help to reconcile some of the inconsistencies found in previous literature.

Abstract: All over the world, people reason dualistically. We consider it more probable that mental states, such as love, continue after biological death than we think bodily states, such as hunger, will continue. However the extent to which culture affects mind-body dualism remains unclear. Here, we draw on a large and erse cross-cultural s le (24 countries, N = 10195) to systematically quantify cultural variation in tendencies for mind-body dualism. Our findings replicate previous work suggesting that mind-body dualism is culturally universal. Furthermore, our experiment reveals that religion lifies dualistic tendencies. At the same time, however, the modal response across most countries was the cessation of all states. In addition, explicit afterlife beliefs were more prevalent than implicit afterlife beliefs (i.e., continuity judgments). Overall, these data suggest that intuitive materialism is the cross-cultural norm, with dualism arising from culturally acquired beliefs.

Abstract: The C19PRC Study aims to assess the psychological, social, and economic impact of the COVID-19 pandemic in the UK, Republic of Ireland, and Spain. This paper describes the the first two waves of the UK survey (the ‘parent’ strand of the Consortium) during March-April 2020. A longitudinal, internet panel survey assessed: (1) COVID-19 related knowledge, attitudes, and behaviours (2) the occurrence of common mental health disorders (e.g. anxiety, depression) as well as the role of (3) psychological factors (e.g. personality, locus of control, resilience) and (4) social and political attitudes (e.g. authoritarianism, social dominance), in influencing the public’s response to the pandemic. Quota s ling was used to recruit a nationally representative (in terms of age, sex, and household income) s le of adults (N=2025), 1406 of whom were followed-up one month later (69.4% retention rate). The baseline s le was representative of the UK population in terms of economic activity, ethnicity, and household composition. Attrition was predicted by key socio-demographic characteristics, and an inverse probability weighting procedure was employed to ensure the follow-up s le was representative of the baseline s le. C19PRC Study data has strong generalisability to facilitate and stimulate interdisciplinary research on important public health questions relating to the COVID-19 pandemic.

Abstract: Objectives The COVID-19 pandemic is one of the greatest global health threats facing humanity in recent memory. This study aimed to explore influences on hygienic practices, a set of key transmission behaviours, in relation to the Capability, Opportunity, Motivation-Behaviour (COM-B) model of behaviour change (Michie et al., 2011).Design Data from the first wave of a longitudinal survey study was used, launched in the early stages of the UK COVID-19 pandemic.Methods Participants were 2025 adults aged 18 and older, representative of the UK population, recruited by a survey company from a panel of research participants. Participants self-reported motivation, capability and opportunity to enact hygienic practices during the COVID-19 outbreak.ResultsUsing regression models, we found that all three COM-B components significantly predicted good hygienic practices, with motivation having the greatest influence on behaviour. Breaking this down further, the sub-scales psychological capability, social opportunity and reflective motivation positively influenced behaviour. Reflective motivation was largely driving behaviour, with those highest in reflective motivation scoring 51% more on the measure of hygienic practices compared with those with the lowest scores.ConclusionsOur findings have clear implications for the design of behaviour change interventions to promote hygienic practices. Interventions should focus on increasing and maintaining motivation to act and include elements that promote and maintain social support and knowledge of COVID-19 transmission. Groups in particular need of targeting for interventions to increase hygienic practices are males and those living in cities and suburbs.

Abstract: Although the COVID-19 pandemic has impacted the psychological wellbeing of some people, there is evidence that many have been much less affected. The Ecological Model of Resilience (EMR) may explain why some in iduals are not resilient whilst others are. In this study we test the EMR in a comparison of UK survey data collected from the Covid-19 Psychological Research Consortium longitudinal study of a representative s le of the UK adult population and data from an Italian arm of the study. We first compare data from the third wave (W3) of the UK arm of the study, collected in July/August 2020, with data from an equivalent s le (N = 1034) and stage of the pandemic in Italy in July 2020. Next, using UK longitudinal data collected from C19PRC Waves 1, 3 and 5, collected between March 2020 and April 2021 we identify the proportion of people who were resilient. Finally, we examine which factors, drawn from the ecological model, predict resilient and non-resilient outcomes.We find that the 72% of the UK s le was resilient, in line with the Italian study. In the cross-sectional logistic regression model, age and self-esteem were significantly associated with resilience whilst death anxiety thoughts, neuroticism, loneliness, and PTSD symptoms related to COVID-19 were significantly associated with Non-Resilient outcomes.In the longitudinal UK analysis, at Wave 5, 80% of the s le was Resilient. Service use, belonging to wider neighbourhood, self-rated health, self-esteem, openness, and externally generated death anxiety were associated with Resilient outcomes. In contrast, PTSD symptoms and loneliness were associated with Non-Resilient outcomes.The EMR effectively explained the results. There were some variables which are amenable to intervention which could increase resilience in the face of similar future challenges.

Abstract: Religious belief is a topic of longstanding interest to psychological science, but the psychology of religious disbelief is a relative newcomer. One prominently discussed model is analytic atheism, wherein analytic thinking overrides religious intuitions and instruction. Consistent with this model, performance-based measures of reliance on analytic thinking predict religious disbelief in WEIRD (Western, Educated, Industrialized, Rich, & Democratic) s les. However, the generality of analytic atheism remains unknown. Drawing on a large global s le (N = 3461) from 13 religiously, demographically, and culturally erse societies, we find that analytic atheism is in fact quite fickle cross-culturally, only appearing robustly in aggregate analyses and in three in idual countries. Such complexity implies a need to revise simplistic theories of religious disbelief as primarily grounded in cognitive style. The results provide additional evidence for culture’s effects on core beliefs, highlighting the power of comparative cultural evidence to clarify core mechanisms of human psychological variation.

Abstract: Jussim argues that the self-fulfilling prophecy and expectancy effects of descriptive stereotypes are not potent shapers of social reality. However, his conclusion that descriptive stereotypes per se do not shape social reality is premature and overly reductionist. We review evidence that suggests descriptive stereotypes do have a substantial influence on social reality, by virtue of their influence on collective action.

Abstract: Adverse childhood experiences (ACEs) are extreme stressors that have a profound impact on cognitive development. Using an explore/exploit foraging paradigm, we demonstrate that ACEs are associated with reduced exploration, leading these in iduals to accumulate fewer rewards from their environment. Using computational modeling, we identify that reduced exploration is associated with ACE-exposed in iduals underweighting reward feedback, which highlights a cognitive mechanism that may link childhood trauma to the onset and maintenance of psychopathology.

Abstract: False claims are a key feature of confabulation, delusion, and anosognosia. In this paper we consider the role of motivational factors in such claims. We review motivational accounts of each symptom and consider the evidence adduced in support of these accounts. In our view the evidence is strongly suggestive of a role for motivational factors in each domain. Before concluding, we widen the focus by outlining a tentative general taxonomy of false claims, including false claims that occur in clinical settings as well as more garden-variety false claims, and incorporating both motivational and nonmotivational approaches to explaining such claims.

Abstract: This paper discusses the ecological case for epistemic innocence: does biased cognition have evolutionary benefits, and if so, does that exculpate human reasoners from irrationality? Proponents of 'ecological rationality' have challenged the bleak view of human reasoning emerging from research on biases and fallacies. If we approach the human mind as an adaptive toolbox, tailored to the structure of the environment, many alleged biases and fallacies turn out to be artefacts of narrow norms and artificial set-ups. However, we argue that putative demonstrations of ecological rationality involve subtle locus shifts in attributions of rationality, conflating the adaptive rationale of heuristics with our own epistemic credentials. By contrast, other cases also involve an ecological reframing of human reason, but do not involve such problematic locus shifts. We discuss the difference between these cases, bringing clarity to the rationality debate.

Abstract: From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting “culpable” limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of “forgivably” limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious – but doxastically 1 noncommittal – action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, only positive illusions meet our criteria.

Abstract: Shevlin et al. (2021) recently demonstrated heterogeneity in mental health and psychological responses to the COVID-19 pandemic over time from a nationally representative s le of UK adults (March–July 2020). Five subpopulations representing either stability, deterioration or improvement in both anxiety-depression and COVID-19 PTSD were identified. The majority of the s le were characterised by low levels of anxiety-depression (56.6%) and COVID-19 traumatic stress (68.3%) during this early phase of the pandemic but some showed deterioration and some showed mental health benefits. Here we extend these findings using two additional survey waves from the C19PRC Study, thereby modelling mental health trajectories for the UK population within the entire first year of the pandemic.

Abstract: Background: Extant research relating to the psychological impact of infectious respiratory disease epidemics andemics suggests that frontline workers are particularly vulnerable.Methods: The current study used data from the first two waves of the United Kingdom (UK) survey of the COVID-19 Psychological Research Consortium (C19PRC) Study to compare frontline workers with the rest of the UK population on prevalence estimates of depression, anxiety, and PTSD during the first week of ‘lockdown’ (Wave 1) and one month later (Wave 2).Results: Compared to the rest of the population, frontline workers generally, and in idual frontline worker groups, had significantly higher prevalence estimates of depression, anxiety, and PTSD during both wave 1 and wave 2. While prevalence estimates of depression significantly increased among Local & National Government Workers from Wave 1 (15.4%) to Wave 2 (38.5%), no significant improvement or deterioration in mental health status was recorded for any other frontline worker group. Multivariate binary logistic regression analysis showed that, beyond other risk factors, food workers were nearly twice as likely as others to screen positive for anxiety, while all frontline worker groups, other than transport workers, were significantly more likely to screen positive for PTSD (Odds Ratios ranged from 1.74 – 3.43). Finally, while frontline workers, generally, were significantly more likely than the general public to have received mental health advice during the pandemic (26.9% versus 20.3% respectively), this was largely reflective of health and social care workers (37.9%).Conclusions: These findings offer timely and valuable information on the psychological health status of UK’s frontline workforce during the early stages of the COVID-19 pandemic and may aid in preparations for their future psychological and mental health support.

Abstract: AbstractObjectives: The COVID-19 Psychological Research Consortium (C19PRC) Study was established in March 2020 to monitor the psychological and socio-economic impact of the pandemic in the UK and other countries. This paper describes the protocol for Wave 6 (August-September 2021). Methods: The survey assessed: COVID-19 related experiences experiences of common mental health disorders psychological characteristics and social and political attitudes. Adults who participated in any previous wave (N=3170) were re-invited to participate, and s le replenishment procedures were conducted to help manage attrition. Weights were calculated using a survey raking algorithm to ensure on-going original panel (commencing at baseline) was nationally representative in terms of gender, age, and household income, amongst other factors. Results: 1643 adults who participated in any previous wave were re-interviewed at Wave 6 (51.8% retention rate). Non-participation at Wave 6 was higher amongst women, younger adults, those in employment, those born outside UK, adults living in cities, and those not living alone. Of the adults recruited into the C19PRC study at baseline, 54.3% (N=1100) participated in Wave 6. An additional 415 new respondents entered the panel at this wave, resulting in cross-sectional s le for Wave 6 of 2058 adults. The raking procedure re-balanced the longitudinal panel to within 1.3% of population estimates for selected socio-demographic characteristics. Conclusion: This paper outlines the growing strength of the publicly available C19PRC Study data for COVID-19-related interdisciplinary research.

Abstract: BackgroundThe COVID-19 pandemic has created an unprecedented global crisis necessitating drastic changes to living conditions, social life, personal freedom and economic activity. No study has yet examined the presence of psychiatric symptoms in the UK population in similar conditions.AimsWe investigated the prevalence of COVID-19 related anxiety, generalised anxiety, depression and trauma symptoms in a representative s le of the UK population during an early phase of the pandemic, and estimated associations with variables likely to influence these symptoms.MethodBetween March 23rd and March 28th 2020, a quota s le of 2025 UK adults 18 years and older, stratified by age, sex and household income, was recruited by online survey company Qualtrics. Participants completed measures of depression (PHQ9), generalised anxiety (GAD7), and trauma symptoms relating to the pandemic (ITQ). Bivariate and multivariate associations were calculated for age, gender, rural vs urban environment, presence of children in the household, income, loss of income, pre-existing health conditions in self and someone close, infection in self and someone close, and perceived risk of infection over the next month.ResultsHigher levels of anxiety, depression and trauma symptoms were reported compared to previous population studies, but not dramatically so. Meeting the criteria for either anxiety or depression, and trauma symptoms was predicted by young age, presence of children in the home, and high estimates of personal risk. Anxiety and depression symptoms were also predicted by low income, loss of income, and pre-existing health conditions in self and other. Specific anxiety about COVID-19 was greater in older participants.Conclusions The UK population, especially older citizens, were largely resilient in the early stages of the pandemic. However, several specific COVID-related variables are associated with psychological distress: particularly having children at home, loss of income because of the pandemic, as well as having a pre-existing health condition, exposure to the virus and high estimates of personal risk. Further similar surveys, particularly of those with children at home, are required as the pandemic progresses.

Abstract: We explored potential contributing psychological factors in a patient ('XF') with focal retrograde amnesia, within the framework proposed by Kopelman (2000, Cognitive Neuropsychology, 17, 585). In particular, we investigated the psychological trait of self-enhancement. We constructed a self-report questionnaire measure of self-enhancement and compared XF's score on this measure with the scores of 61 control participants. XF was found to have a significantly greater level of self-enhancement than the entire control group, and also than a smaller s le of age- and sex-matched controls. We propose that heightened self-enhancement may reflect a premorbid tendency that potentially predisposes in iduals to develop retrograde amnesia.

Abstract: The COVID-19 Psychological Research Consortium (C19PRC) Study aims to assess and monitor the psychological and social impact of the coronavirus (COVID-19) pandemic in the general population, using longitudinal surveys and mixed-methods studies in multiple countries. The first strand of the study, an internet-based panel survey, was launched in the UK in March 2020 during the earliest stages of the pandemic in that country (hereafter referred to as C19PRC-UKW1). This paper describes (1) the development, design and content for C19PRC-UKW1, which was informed by the extant evidence base on the psychosocial impact of previous global outbreaks of similar severe acute respiratory syndromes (e.g. SARS, H1N1, MERS) (2) the specific socio-economic and political context of the C19PRC-UKW1 (3) the recruitment of a large s le of UK adults aged 18 years and older (n=2025) via an internet-based panel survey (4) the representativeness of the C19PRC-UKW1 s le compared to the UK adult population in terms of important sociodemographic characteristics (e.g. age, sex, household income, etc.) and (5) future plans for C19PRC Study including follow-up survey waves in the UK, supplementary non-survey based study strands linking from the C19PRC-UKW1 and the roll-out of the study to other countries.

Abstract: Conspiracy theories about COVID-19 have proliferated during the global pandemic, and their rapid spread among certain groups inthe population has important implications for policy attitudes (e.g., motivation to engage in social distancing and willingness to vaccinate). Using survey data from two waves of a nationally representative, longitudinal study of life in lockdown in the UK (N = 1,406), we analyze the factors associated with belief in three theories related to COVID-19, namely that it 1) originated in a meat market in Wuhan, China, 2) was developed in a lab in Wuhan, China, and 3) is caused by 5G mobile networks. Using a dual-factor model, we test how cognitive ability and motivations affect susceptibility to misinformation. Our findings suggest that motivational and political dispositions, as well as the sources from which people derive COVID-19 related information, are strongly associated with belief in conspiracy theories about the virus, though these predictors vary among conspiracies. Belief in the Chinese lab conspiracy is associated with right-wing authoritarianism (RWA), social dominance orientation (SDO) and a preference for tabloid newspapers, while belief in the 5G network origin story is associated with social dominance orientation and a tendency to derive information on COVID-19 from social media. Moreover, we find that motivational factors like RWA and SDO have larger effect sizes than COVID-19 related anxiety, a desire for certainty, cognitive reasoning ability, or even general conspiracy ideation (in the case of 5G belief). These findings suggest that efforts to mitigate the potential damage caused by conspiracy theories, for ex le, by increasing education and awareness, may be inadequate because they miss a larger story, namely the role that politically motivated reasoning plays in making in iduals susceptible to misinformation, and the propagation of conspiracies through networks and channels that reinforce these inaccurate worldviews.

Abstract: People tend to evaluate information from reliable sources more favourably, but it is unclear exactly how perceivers' worldviews interact with this source credibility effect. In a large and erse cross-cultural s le (N = 10,195 from 24 countries), we presented participants with obscure, meaningless statements attributed to either a spiritual guru or a scientist. We found a robust global source credibility effect for scientific authorities, which we dub `the Einstein effect': across all 24 countries scientists hold greater authority than spiritual source, even among highly committed religious people, who are relatively also more credulous of nonsense from scientists than they are of nonsense from spiritual gurus. Additionally, in idual religiosity predicted a weaker relative preference for the statement from the scientist vs. the spiritual guru, and was more strongly associated with credibility judgments for the guru than the scientist. Independent data on explicit trust ratings across 143 countries mirrored the experimental patterns. These findings suggest that irrespective of religious worldview, science is a powerful and universal heuristic that signals the reliability of information.

Abstract: Adolescence is a period of heightened exploration relative to adulthood and childhood. This predisposition has been linked with negative behaviours related to risk-taking, including dangerous driving, substance misuse and risky sexual practices. However, recent models have argued that adolescents’ heightened exploration serves a functional purpose within the lifespan, allowing adolescents to develop experiential knowledge of their surroundings. Yet, there is limited evidence that heightened exploration in adolescence is associated with positive outcomes. To address this, the present pre-registered study utilised a foraging paradigm with a s le of adolescents aged 16-17 (N=68) and of adults aged 21 and above (N=69). Participants completed a patch foraging task, which required them to choose between exploiting a known resource which gradually yields fewer rewards, and exploring a novel, unknown resource with a fresh distribution of rewards. Findings demonstrated that adolescents explored more than adults, which – in the context of the current task – represented more optimal patch foraging behaviour. These findings indicate that adolescents’ heightened exploration can be beneficial, as they were able to effectively navigate unknown environments and accrue rewards more successfully than adults. This provides evidence that heightened exploration in adolescence, relative to adulthood, can lead to positive outcomes and contributes to our understanding of the role increased novelty-seeking plays at this point in the lifespan.

Abstract: Objectives: Hesitance and resistance to COVID-19 vaccination poses a serious challenge to achieving adequate vaccine uptake in the general population. Cross-sectional data from the early months of the pandemic indicates that approximately one-third of adults in multiple nations are hesitant or resistant to a vaccine for COVID-19. Using longitudinal data, we tracked changes in attitudes to COVID-19 vaccination during the pandemic.Study Design: A quantitative, longitudinal design.Method: Nationally representative s les of the adult general population of the Republic of Ireland (N = 1,041) and the United Kingdom (N = 2,025) were assessed for their attitudes towards COVID-19 vaccination at three points from March to August 2020.Results: Statistically significant increases in resistance to COVID-19 vaccination were observed in Irish (from 9.5% to 18.1%) and British (6.2% to 10%) adults. Conclusion: Resistance to vaccination has significantly increased in two European nations as the pandemic has progressed. Growing resistance to COVID-19 vaccination will pose a challenge to public health officials responsible for ensuring sufficient vaccine coverage.

Abstract: Self-esteem is one of the most prominent and influential constructs in psychological science, yet very few neuropsychological/neuroscientific investigations have been undertaken in this area of research. The current study investigated the possibility of hemispheric lateralisation of self-esteem. By creating an auditory version of the Implicit Association Test (IAT) for self-esteem, we were able to present stimuli dichotically and thereby compare left- versus right-hemispheric measurements of self-esteem in 46 healthy adults. Although left- and right-hemispheric self-esteem measurements were correlated, within-participant analysis revealed that self-esteem levels (as reflected by IAT score) were significantly greater when elicited under right-ear presentation (reflecting left-hemispheric processing). We interpret this asymmetry with reference to the approach-withdrawal model of emotion processing and suggest avenues for future research.

Abstract: Adverse Childhood Experiences (ACEs) are extreme stressors that lead to negative psychosocial outcomes in adulthood. Non-human animals explore less after exposure to early stress. Therefore, in this pre-registered study we hypothesised that reduced exploration following ACEs would also be evident in human adults. Further, we predicted that adults with ACEs, in a foraging task, would adopt a decision-making policy that relies on the most recent reward feedback, a rational strategy for unstable environments. We analysed data from 145 adult participants, 47 with four or more ACEs and 98 with fewer than four ACEs. In the foraging task, participants evaluated the trade-off between exploiting a known patch with diminishing rewards and exploring a novel one with a fresh distribution of rewards. Using computational modelling, we quantified the degree to which participants’ decisions weighted recent feedback. As predicted, participants with ACEs explored less. However, contrary to our hypothesis, they underweighted recent feedback. These unexpected findings indicate that early adversity may d en reward sensitivity. Our results may help to identify cognitive mechanisms that link childhood trauma to the onset of psychopathology.

Abstract: The over-purchasing and hoarding of necessities is a common response to crises, especially in developed economies where there is normally an expectation of plentiful supply. This behaviour was observed internationally during the early stages of the Covid-19 pandemic. In the absence of actual scarcity, this behaviour can be described as ‘panic buying’ and can lead to temporary shortages. However, there have been few psychological studies of this phenomenon. Here we propose a psychological model of over-purchasing informed by animal foraging theory and make predictions about variables that predict over-purchasing by either exacerbating or mitigating the anticipation of future scarcity. These variables include additional scarcity cues (e.g. loss of income), distress (e.g. depression), psychological factors that draw attention to these cues (e.g. neuroticism) or to reassuring messages (eg. analytical reasoning) or which facilitate over-purchasing (e.g. income). We tested our model in parallel nationally representative internet surveys of the adult general population conducted in the United Kingdom (UK: N = 2025) and the Republic of Ireland (RoI: N = 1041) 52 and 31 days after the first confirmed cases of COVID-19 were detected in the UK and RoI, respectively. About three quarters of participants reported minimal over-purchasing. There was more over-purchasing in RoI vs UK and in urban vs rural areas. When over-purchasing occurred, in both countries it was observed across a wide range of product categories and was accounted for by a single latent factor. It was positively predicted by household income, the presence of children at home, psychological distress (depression, death anxiety), threat sensitivity (right wing authoritarianism) and mistrust of others (paranoia). Analytic reasoning ability had an inhibitory effect. Predictor variables accounted for 36% and 34% of the variance in over-purchasing in the UK and RoI respectively. With some caveats, the data supported our model and points to strategies to mitigate over-purchasing in future crises.

Abstract: The impact of our desires and preferences upon our ordinary, everyday beliefs is well-documented [Gilovich, T. (1991). How we know what isn't so: The fallibility of human reason in everyday life. New York: The Free Press.]. The influence of such motivational factors on delusions, which are instances of pathological misbelief, has tended however to be neglected by certain prevailing models of delusion formation and maintenance. This paper explores a distinction between two general classes of theoretical explanation for delusions the motivational and the deficit. Motivational approaches view delusions as extreme instances of self-deception as defensive attempts to relieve pain and distress. Deficit approaches, in contrast, view delusions as the consequence of defects in the normal functioning of belief mechanisms, underpinned by neuroanatomical or neurophysiological abnormalities. It is argued that although there are good reasons to be sceptical of motivational theories (particularly in their more floridly psychodynamic manifestations), recent experiments confirm that motives are important causal forces where delusions are concerned. It is therefore concluded that the most comprehensive account of delusions will involve a theoretical unification of both motivational and deficit approaches.

Abstract: Affective polarization describes the phenomenon whereby people identifying as Republican or Democrat tend to view opposing partisans negatively and co-partisans positively. Though extensively studied, there remain important gaps in scholarly understanding of affective polarization. In particular, (a) how it relates to the distinct behavioural phenomena of in-party “love” vs. out-party hostility and (b) to what extent it reflects a generalized evaluative disparity between partisans vs. a domain-specific disparity in evaluation. We report the results of an investigation that bears on both of these questions. Specifically, drawing on recent trends in political science and psychology, we hypothesize that moral polarization—the tendency to view opposing partisans’ moral character negatively, and co-partisans’ moral character positively—will be associated with behavioural hostility towards the out-party. We test this hypothesis in two preregistered studies comprising behavioural measures and large convenience s les of US partisans (combined N = 1354). Our results strike an optimistic chord: Taken together, they suggest that this association is probably small and somewhat tenuous. Though moral polarization itself was large—perhaps exceeding prior estimates of trait affective polarization—even the most morally polarized partisans appeared reluctant to engage in a mild form of out-party hostility. These findings converge with recent evidence that polarization—moral or otherwise—has yet to translate into the average US partisan wanting to express hostile and directly discriminatory behaviour toward their out-party counterparts.

Abstract: The COVID-19 pandemic has led to unprecedented changes in the day-to-day behaviours of populations globally, especially in areas where social distancing rules have been mandated. Understanding the cognitive mechanisms underlying (un)successful behaviour change around social distancing is crucial to inform public health policy for both the current and future crises.In this study, we utilise tasks probing delay discounting (the preference for immediate versus delayed rewards) and patch foraging (evaluating the trade-off between exploiting a known resource and exploring an unknown one) to investigate cognitive predictors of social distancing and mental health symptoms. Participants (N=442) were recruited from a large UK cohort (N=2025) nationally representative in age, gender and income.Greater sensitivity to reward magnitude during delay discounting predicted lower adherence to social distancing measures and higher levels of mood and anxiety symptoms. In addition, under-valuing recently s led information during foraging separately predicted greater violation of social distancing. Analyses examining cognitive factors underpinning social distancing behaviour across two time points (early and late phases of the pandemic) additionally revealed that greater sensitivity to magnitude of rewards on offer during delay discounting predicted a greater decline in psychological inclination to maintain social distancing. Moreover, under-valuing recent information during foraging separately predicted less motivation to engage in social distancing during the established phase of the pandemic. The findings suggest that those who typically regulate their mood through behaviours that bring about immediate reward are also those who struggle to maintain social distancing. Further, those who adapt more quickly to new information showed better ability to change their behaviour in response to public health measures. These findings highlight the need for public health initiatives that bolster sustained confidence in planning around social distancing by emphasising the immediate rewards to self as well as longer term benefits.

Abstract: Most people report that they are superior to the average person on various moral traits. The psychological causes and social consequences of this phenomenon have received considerable empirical attention. The behavioral correlates of self-perceived moral superiority, however, remain unknown. We present the results of two preregistered studies (Study 1, N=827 Study 2, N=825) in which we indirectly assessed participants’ self-perceived moral superiority, and used two incentivized economic games to measure their engagement in moral behavior. Across studies, self-perceived moral superiority was unrelated to trust in others and to trustworthiness, as measured by the Trust Game and unrelated to fairness, as measured by the Dictator Game. This pattern of findings was robust to a range of analyses, and, in both studies, Bayesian analyses indicated moderate support for the null over the alternative hypotheses. We interpret and discuss these findings, and highlight interesting avenues for future research on this topic.

Abstract: Identifying and understanding COVID-19 vaccine hesitancy within distinct populations may aid future public health messaging. Using nationally representative data from the general adult populations of Ireland ( N = 1041) and the United Kingdom (UK N = 2025), we found that vaccine hesitancy/resistance was evident for 35% and 31% of these populations respectively. Vaccine hesitant/resistant respondents in Ireland and the UK differed on a number of sociodemographic and health-related variables but were similar across a broad array of psychological constructs. In both populations, those resistant to a COVID-19 vaccine were less likely to obtain information about the pandemic from traditional and authoritative sources and had similar levels of mistrust in these sources compared to vaccine accepting respondents. Given the geographical proximity and socio-economic similarity of the populations studied, it is not possible to generalize findings to other populations, however, the methodology employed here may be useful to those wishing to understand COVID-19 vaccine hesitancy elsewhere.

Abstract: Globally, rivers are a common drowning location. In Australia, rivers are the leading location for fatal drowning. Limited information exists on exposure and impact on river drowning risk. Australian unintentional fatal river drowning data (sourced from coronial records) and nationally representative survey data on river visitation were used to estimate river drowning risk based on exposure for adults (18 years and older). Differences in river drowning rates per 100 000 (population and exposed population) were examined by sex, age group, activity prior to drowning, alcohol presence and watercraft usage. Between 1 January 2014 and 31 December 2016, 151 people drowned in Australian rivers 86% male and 40% aged 18-34 years. Of survey respondents, 73% had visited a river within the last 12 months. After adjusting for exposure: males were 7.6 times more likely to drown at rivers female drowning rate increased by 50% (0.06-0.09 per 100 000) males aged 75+ years and females aged 55-74 years were at highest risk of river drowning and swimming and recreating pose a high risk to both males and females. After adjusting for exposure, males were more likely to drown with alcohol present (RR=8.5 95% CI 2.6 to 27.4) and in a watercraft-related incident (RR=25.5 95% CI 3.5 to 186.9). Calculating exposure for river drowning is challenging due to erse usage, time spent and number of visits. While males were more likely to drown, the differences between males and females narrow after adjusting for exposure. This is an important factor to consider when designing and implementing drowning prevention strategies to effectively target those at risk.

Abstract: Delusions are distressing and disabling symptoms of various clinical disorders. Delusions are associated with an aberrant and apparently contradictory treatment of evidence, characterized by both excessive credulity (adopting unusual beliefs on minimal evidence) and excessive rigidity (holding steadfast to these beliefs in the face of strong counterevidence). Here we attempt to make sense of this contradiction by considering the literature on epistemic vigilance. Although there is little evolutionary advantage to scrutinizing the evidence our senses provide, it pays to be vigilant toward ostensive evidence—information communicated by others. This asymmetry is generally adaptive, but in deluded in iduals the scales tip too far in the direction of the sensory and perceptual, producing an apparently paradoxical combination of credulity (with respect to one’s own perception) and skepticism (with respect to the testimony of others).

Abstract: Successful delivery of a COVID-19 vaccine may be undermined if populations are not receptive to inoculation as a primary public health strategy for combatting the virus. We gathered nationally representative data from the general adult populations of Ireland (N=1,041) and the United Kingdom (UK N=2,025) to determine rates of hesitancy and resistance to a future COVID-19 vaccine and to identify and psychologically profile vaccine hesitant/resistant in iduals in a way that might aid future public health messaging. Vaccine hesitancy was evident for 26% and 25% of Irish and UK s les, respectively, while vaccine resistance was evident for 9% and 6%, respectively. Vaccine hesitant/resistant respondents in Ireland and the UK differed in relation to a number of sociodemographic, political, and health-related variables, but were similar across a broad array of psychological constructs. In both populations, those who were resistant to a COVID-19 vaccine were less likely to obtain information about the pandemic from traditional and authoritative sources and had similar levels of mistrust in these sources. The current findings may help public health officials to more effectively target vaccine hesitant and resistant in iduals, develop effective communication strategies that take into account their specific psychological dispositions, and leverage dissemination channels that can successfully reach these in iduals.

Abstract: People tend to evaluate information from reliable sources more favourably, but it is unclear exactly how perceivers' worldviews interact with this source credibility effect. In a large and erse cross-cultural s le (N = 10,195 from 24 countries), we presented participants with obscure, meaningless statements attributed to either a spiritual guru or a scientist. We found a robust global source credibility effect for scientific authorities, which we dub 'the Einstein effect': across all 24 countries and all levels of religiosity, scientists held greater authority than spiritual gurus. In addition, in idual religiosity predicted a weaker relative preference for the statement from the scientist compared with the spiritual guru, and was more strongly associated with credibility judgements for the guru than the scientist. Independent data on explicit trust ratings across 143 countries mirrored our experimental findings. These findings suggest that irrespective of one's religious worldview, across cultures science is a powerful and universal heuristic that signals the reliability of information.

Abstract: Bentall and colleagues (Bentall & Kaney, 1996 Kinderman & Bentall, 1996, 1997) claim that persecutory delusions are constructed defensively, for the maintenance of self-esteem. A central prediction of their model is that such delusions will be associated with discrepancies between overt and covert self-esteem. The present study employed a new methodology that has been widely used in investigations of implicit attitudes, the Implicit Association Test (IAT Greenwald, McGhee, & Schwartz, 1998), to assess covert self-esteem and to test the above prediction. Overt self-esteem was assessed using the Rosenberg Self-Esteem Scale and an adjective self-relevance ratings measure. These measures were administered to 10 patients with acute persecutory delusions, 10 patients with remitted persecutory delusions, and 19 healthy control participants. Patients with persecutory delusions were found to have lower covert self-esteem (as assessed using the IAT) than healthy controls and patients with remitted persecutory delusions. On two measures of overt self-esteem, however, the persecutory deluded group did not differ significantly from the other groups once the effects of comorbid depression had been taken into account. These results are thus consistent with a model of persecutory delusions as serving the defensive function of maintaining self-esteem.

Abstract: Purpose: The COVID-19 pandemic has affected the way many in iduals go about their daily lives. This study attempted to model the complexity of change in lifestyle quality as a result of the COVID-19 pandemic and its context within the UK adult population.Methods: Data from the COVID-19 Psychological Research Consortium Study (Wave 3, July 2020 N=1166) were utilised. A measure of COVID-19-related lifestyle change captured how in iduals’ lifestyle quality had been altered as a consequence of the pandemic. Exploratory factor analysis and latent profile analysis were used to identify distinct lifestyle quality change subgroups, while multinomial logistic regression analysis was employed to describe class membership.Results: Five lifestyle dimensions, reflecting partner relationships, health, family and friend relations, personal and social activities, and work life were identified by the EFA, while seven classes characterised by distinct patterns of change across these dimensions emerged from the LPA: (1) Better overall (3.3%), (2) Worse except partner relations (6.0%), (3) Worse overall (2.5%), (4) Better relationships (9.5%), (5) Better except partner relations (4.3%), (6) No different (67.9%), and (7) Worse partner relations only (6.5%). Predictor variables differentiated membership of classes. Notably, classes 3 and 7 were associated with poorer mental health (COVID-19 related PTSD and suicidal ideation).Conclusions: Four months into the pandemic, most in iduals’ lifestyle quality remained largely unaffected by the crisis. Concerningly however, a substantial minority (15%) experienced worsened lifestyles compared to before the pandemic. In particular, a pronounced deterioration in partner relations seemed to constitute the more severe pandemic-related lifestyle change.

Abstract: Averageness and symmetry are attractive in Western faces and are good candidates for biologically based standards of beauty. A hallmark of such standards is that they are shared across cultures. We examined whether facial averageness and symmetry are attractive in non-Western cultures. Increasing the averageness of in idual faces, by warping those faces towards an averaged composite of the same race and sex, increased the attractiveness of both Chinese (experiment 1) and Japanese (experiment 2) faces, for Chinese and Japanese participants, respectively. Decreasing averageness by moving the faces away from an average shape decreased attractiveness. We also manipulated the symmetry of Japanese faces by blending each original face with its mirror image to create perfectly symmetric versions. Japanese raters preferred the perfectly symmetric versions to the original faces (experiment 2). These findings show that preferences for facial averageness and symmetry are not restricted to Western cultures, consistent with the view that they are biologically based. Interestingly, it made little difference whether averageness was manipulated by using own-race or other-race averaged composites and there was no preference for own-race averaged composites over other-race or mixed-race composites (experiment 1). We discuss the implications of these results for understanding what makes average faces attractive. We also discuss some limitations of our studies, and consider other lines of converging evidence that may help determine whether preferences for average and symmetric faces are biologically based.

Abstract: Unrealistic optimism refers to the pervasive tendency of healthy in iduals to underestimate their likelihood of future misfortune, including illness. The phenomenon shares a qualitative resemblance with anosognosia, a neurological disorder characterized by a deficient appreciation of manifest current illness or impairment. Unrealistic optimism and anosognosia have been independently associated with a region of right inferior frontal gyrus, the pars opercularis. Moreover, anosognosia is temporarily abolished by vestibular stimulation, particularly by irrigation of the left (but not right) ear with cold water, a procedure known to activate the right inferior frontal region. We therefore hypothesized that left caloric stimulation would attenuate unrealistic optimism in healthy participants. Thirty-one healthy right-handed adults underwent cold-water caloric vestibular stimulation of both ears in succession. During each stimulation episode, and at baseline, participants estimated their own relative risk of contracting a series of illnesses in the future. Compared to baseline, average risk estimates were significantly higher during left-ear stimulation, whereas they remained unchanged during right-ear stimulation. Unrealistic optimism was thus reduced selectively during cold caloric stimulation of the left ear. Our results point to a unitary mechanism underlying both anosognosia and unrealistic optimism, and suggest that unrealistic optimism is a form of subclinical anosognosia for prospective symptoms.

Abstract: Recent evidence indicates that priming participants with religious concepts promotes prosocial sharing behaviour. In the present study, we investigated whether religious priming also promotes the costly punishment of unfair behaviour. A total of 304 participants played a punishment game. Before the punishment stage began, participants were subliminally primed with religion primes, secular punishment primes or control primes. We found that religious primes strongly increased the costly punishment of unfair behaviours for a subset of our participants—those who had previously donated to a religious organization. We discuss two proximate mechanisms potentially underpinning this effect. The first is a ‘supernatural watcher’ mechanism, whereby religious participants punish unfair behaviours when primed because they sense that not doing so will enrage or disappoint an observing supernatural agent. The second is a ‘behavioural priming’ mechanism, whereby religious primes activate cultural norms pertaining to fairness and its enforcement and occasion behaviour consistent with those norms. We conclude that our results are consistent with dual inheritance proposals about religion and cooperation, whereby religions harness the byproducts of genetically inherited cognitive mechanisms in ways that enhance the survival prospects of their adherents.

Abstract: Following the 2016 EU referendum on Britain's membership in the European Union, many people described themselves as “Leavers” or “Remainers.” Here, we examine the emotional responses associated with Brexit identities using survey data collected from two nationally representative s les of the British public in 2019 ( N = 638) and 2021 ( N = 2,058). Confirmatory factor analysis indicated that many in both s les had coherent Leave or Remain identities. Remain and, to a lesser extent, Leave identities (regardless of how people actually voted in the referendum) predicted distress about Brexit‐related events and clinical symptoms of depression and anxiety at both time points. Structural equation models suggested that the effect of identities on symptoms was largely mediated by distress about Brexit‐related events. We demonstrate a lasting impact of Brexit on the mental health of UK citizens and show that the formation of novel political identities has been more important in this process than voting behavior.

Abstract: Objectives: This paper describes fieldwork procedures for the fifth wave of the COVID-19 Psychological Research Consortium (C19PRC) Study, conducted during March-April 2021. The C19PRC Study was established in March 2020 to monitor the psychological and socio-economic impact of the COVID-19 pandemic in the UK and other countries. Methods: The survey wave assessed: COVID-19 related experiences the occurrence of common mental health disorders psychological factors and social and political attitudes – to facilitate statistical analyses to determine how these constructs on influenced the public’s response to the pandemic. Adults who participated in any previous survey wave (N=4949) were re-contacted and invited to participate. Weights were calculated using a survey raking algorithm to ensure that the longitudinal panel was nationally representative in terms of gender, age, and household income, amongst other factors. Results: Overall, 2520 adults participated in this wave. A total of 2377 adults who participated in the previous survey wave (i.e., Wave 4 of the C19PRC Study, conducted November-December 2020) were successfully recontacted and provided full interviews at Wave 5 (61.5% retention rate). Attrition between these two waves was predicted by factors such as younger age, lower household income, having children living in the household, and current or past experiences of treatment for mental health difficulties. Of the adults recruited into the C19PRC study at baseline, 57.4% (N=1162) participated in the fifth wave. The raking procedure successfully re-balanced the longitudinal panel to within 1.5% of population estimates for selected socio-demographic characteristics. Conclusion: This paper outlines the growing strength of the publicly available C19PRC Study data to facilitate and stimulate interdisciplinary research aimed at addressing important public health questions relating to the COVID-19 pandemic.

Abstract: That delusional and delusion-prone in iduals "jump to conclusions" on probabilistic reasoning tasks is a key finding in cognitive neuropsychiatry. Here we focused on a less frequently investigated aspect of "jumping to conclusions" (JTC): certainty judgments. We incorporated rigorous procedures from experimental economics to eliminate potential confounds of miscomprehension and motivation and systematically investigated the effect of incentives on task performance. Low- and high-delusion-prone participants (n = 109) completed a series of computerised trials on each trial, they were shown a black or a white fish, caught from one of the two lakes containing fish of both colours in complementary ratios. In the betting condition, participants were given £4 to distribute over the two lakes as they wished in the control condition, participants simply provided an estimate of how probable each lake was. Deviations from Bayesian probabilities were investigated. Whereas high-delusion-prone participants in both the control and betting conditions underestimated the Bayesian probabilities (i.e. were conservative), low-delusion-prone participants in the control condition underestimated but those in the betting condition provided accurate estimates. In the control condition, there was a trend for high-delusion-prone participants to give higher estimates than low-delusion-prone participants, which is consistent with previous reports of "jumping to conclusions" in delusion-prone participants. However, our findings in the betting condition, where high-delusion-prone participants provided lower estimates than low-delusion-prone participants (who were accurate), are inconsistent with the jumping-to-conclusions effect in both a relative and an absolute sense. Our findings highlight the key role of task incentives and underscore the importance of comparing the responses of delusion-prone participants to an objective rational standard as well as to the responses of non-delusion-prone participants.

Abstract: Two different modes of theorising about delusions are explored. On the one hand is the motivational approach, which regards delusions as serving a defensive, palliative, even potentially adaptive function. On the other, is the cognitive deficit approach, which conceptualises delusions as explicitly pathological, involving abnormalities in ordinary cognitive processes. The former approach, prominently exemplified by the psychoanalytic tradition, was predominant historically, but has been challenged in recent years by the latter. Some grievances against psychoanalytic theory are briefly discussed, and it is argued that although the reasons for psychoanalysis falling into scientific disrepute are partly justified, the psychodynamic notion that motivation has access to the mechanisms of belief formation is of potentially crucial theoretical utility. A variety of possible syntheses of the two theoretical modes are therefore explored, in the belief that the most comprehensive account of delusions will involve a theoretical unification of both styles of explanation. Along the way, an attempt is made to locate the notions delusion, defence, and self-deception in a shared theoretical space.

Abstract: Young and colleagues (e.g. Young, A. W., & Leafhead, K. M. (1996). Betwixt life and death: case studies of the Cotard delusion. In P. W. Halligan & J. C. Marshall (Eds.), Method in madness: Case studies in cognitive neuropsychiatry. Mahway, NJ: Lawrence Erlbaum Associates.) have suggested that cases of the Cotard delusion (the belief that one is dead) result when a particular perceptual anomaly (caused by a disruption to the affective component of visual recognition) occurs in the context of an internalising attributional style. This hypothesis has not previously been tested directly. We report here an investigation of attributional style in a 24-year-old woman with Cotard delusion ("LU"). LU's attributional style (and that of ten healthy control participants) was assessed using the Internal, Personal and Situational Attributions Questionnaire (Kinderman, P., & Bentall, R. P. (1996). A new measure of causal locus: the internal, personal and situational attributions questionnaire. Personality and In idual Differences, 20(2), 261-264.). LU showed a significantly greater proportion of internalising attributions than the control group, both overall and for negative events specifically. The results obtained thus support an association of Cotard delusion with an internalising attributional style, and are therefore consistent with the account of Young and colleagues. The potential brain basis of Cotard delusion is discussed.

Abstract: False beliefs can spread within societies even when they are costly and when in iduals share access to the same objective reality. Research on the cultural evolution of misbeliefs has demonstrated that a social context can explain what people think, but not whether it also explains how people think. We shift the focus from the diffusion of false beliefs to the diffusion of suboptimal belief-formation strategies, and identify a novel mechanism whereby misbeliefs arise and spread. We show that, when in idual decision-makers have access to the data-gathering behaviour of others, the tendency to make decisions on the basis of insufficient evidence is lified, increasing the rate of incorrect, costly decisions. We argue that this mechanism fills a gap in current explanations of problematic, widespread misbeliefs such as climate change denial.
