Abstract: This study modified food attentional biases via computerized attentional bias modification training and examined the effects on food intake. Overweight women were randomly allocated to (1) direct attention away from food (“attentional-training”), (2) direct attention at random to food or neutral (“placebo”), or (3) no training (“control”). In iduals then completed a taste test. Those in the attentional-training consumed on average 600 kJ less of total food compared to the placebo. Those in the attentional-training had a reduction in food attentional bias compared to the placebo group, when controlling for executive function. Attentional-training seems to reduce high-calorie intake in overweight women.

Abstract: This study assesses age-related differences in the weighting and integration of appearance and behavior cues to trustworthiness. The aim is to assess whether it becomes more difficult with age to detect a cheater in disguise. Young and older adults invested real money in a repeated trust game with trustees who varied on facial expression (smiling, neutral, angry) and return rate (high, low). Trustees were also rated for trustworthiness pre- and post-trust game. Young and older adults learned to disregard appearances to invest more in trustees providing high relative to low returns. Both groups also updated ratings of trustworthiness from pre- to post-trust game in the direction of behavior that was incongruent with appearance. Notably, young (but not older) adults updated ratings of smiling trustees with a high return rate (i.e., returned money on 8 of 10 investments) to reflect reduced trustworthiness in line with the 2 instances of cheating from those trustees. The findings show that there are no age-related differences in the way that obvious cheating in disguise is punished with reduced trustworthiness ratings. However, older adults are less vigilant to more subtle cheating in disguise, or are more forgiving of transgressions perceived as minor.

Abstract: Emotional facial expressions evoke rapid, involuntary, and covert facial reactions in the perceiver that are consistent with the emotional valence of the observed expression. These responses are believed to be an important low-level mechanism contributing to the experience of empathy, which some have argued rely on a simulation mechanism subserved by the human mirror neuron system (MNS). Because schizophrenia is associated with pervasive social cognitive difficulties which have been linked to structural abnormalities in the MNS network, the aim of the present study was to provide the first assessment of how rapid facial mimicry reactions (within 1000 ms poststimulus onset) are affected in schizophrenia. Activity in the corrugator supercilii and zygomaticus major muscle regions was quantified using electromyography while in iduals with schizophrenia ( n = 25) and controls ( n = 25) viewed images of happy and angry facial expressions. In contrast to controls, in iduals with schizophrenia demonstrated atypical facial mimicry reactions which were not associated with any clinical features of the disorder. These data provide evidence for a low-level disruption that may be contributing to empathizing deficits in schizophrenia and are discussed in relation to neuropsychological models of empathy and schizophrenia.

Abstract: The process model of emotion regulation (ER) is based on stages in the emotion generative process at which regulation may occur. This meta-analysis examines age-related differences in the subjective, behavioral, and physiological outcomes of instructed ER strategies that may be initiated after an emotional event has occurred attentional deployment, cognitive change, and response modulation. Within-process strategy, stimulus type, and valence were also tested as potential moderators of the effect of age on ER. A systematic search of the literature identified 156 relevant comparisons from 11 studies. Few age-related differences were found. In our analysis of the subjective outcome of response modulation strategies, young adults used expressive enhancement successfully ( g = 0.48), but not expressive suppression ( g = 0.04). Response modulation strategies had a small positive effect among older adults, and enhancement vs suppression did not moderate this success ( g = 0.31 and g = 0.10, respectively). Young adults effectively used response modulation to regulate subjective emotion in response to pictures ( g = 0.41) but not films ( g = 0.01). Older adults were able to regulate in response to both pictures ( g = 0.26) and films ( g = 0.11). Interestingly, both age groups effectively used detached reappraisal, but not positive reappraisal to regulate emotional behavior. We conclude that, in line with well-established theories of socioemotional aging, there is a lack of evidence for age differences in the effects of instructed ER strategies, with some moderators suggesting more consistent effectiveness for older compared to younger adults.

Abstract: The degree to which older adults experience emotional empathy and show subsequent prosocial behavior versus experience personal distress in response to another's distress remains unclear. Young (n = 40 17-29 years) and older (n = 39 61-82 years) adults watched videos of in iduals expressing pain or no pain. Pain mimicry was recorded using facial electromyography. Participants were then asked if they would spend the remaining time helping the experimenter. Self-reported tendency to suppress or reappraise emotion was assessed, as well as trait and state emotional empathy and personal distress. Pain mimicry was associated with reduced trait suppression in older adults. In both age groups, greater emotional empathy, averaged across video condition, was associated with increased helping. In addition, relative to young adults, older adults reported more personal distress and emotional reactivity in response to the videos but were just as willing to help. They also put more effort into helping. These findings contribute to clarification of mixed previous evidence regarding the experience of emotional empathy in young versus older adulthood. We discuss the importance of considering additional subcomponents of empathy such as emotion regulation, while also accounting for the relevance of the empathy induction to each age group.

Abstract: Gaze following is the primary means of establishing joint attention with others and is subject to age-related decline. In addition, young but not older adults experience an own-age bias in gaze following. The current research assessed the effects of subconscious processing on these age-related differences. Participants responded to targets that were either congruent or incongruent with the direction of gaze displayed in supraliminal and subliminal images of young and older faces. These faces displayed either neutral (Study 1) or happy and fearful (Study 2) expressions. In Studies 1 and 2, both age groups demonstrated gaze-directed attention by responding faster to targets that were congruent as opposed to incongruent with gaze-cues. In Study 1, subliminal stimuli did not attenuate the age-related decline in gaze-cuing, but did result in an own-age bias among older participants. In Study 2, gaze-cuing was reduced for older relative to young adults in response to supraliminal stimuli, and this could not be attributed to reduced visual acuity or age group differences in the perceived emotional intensity of the gaze-cue faces. Moreover, there were no age differences in gaze-cuing when responding to subliminal faces that were emotionally arousing. In addition, older adults demonstrated an own-age bias for both conscious and subconscious gaze-cuing when faces expressed happiness but not fear. We discuss growing evidence for age-related preservation of subconscious relative to conscious social perception, as well as an interaction between face age and valence in social perception.

Abstract: Whilst affective empathy is concerned with one's emotional response to the affective state of another, cognitive empathy refers to one's understanding of another's mental state, and deficits in both are believed to contribute to the social behavioral abnormalities associated with schizophrenia. The present study aimed to test whether in idual differences in normally distributed schizotypal personality traits are related to cognitive and affective empathy, and whether any observed association between schizotypy and empathy mediates the relationship between schizotypy and (reduced) social functioning. Non-clinical volunteers (N=223) completed measures of schizotypal personality, cognitive and affective empathy, social functioning and negative affect. The results indicated that higher schizotypy was associated with reduced empathy, poorer social functioning and increased negative affect. Of the specific schizotypal dimensions (positive, negative and disorganized), only negative schizotypy was significantly associated with social functioning, and this relationship persisted even after controlling for negative affect. Further, affective empathy functioned as a partial mediator in this relationship. These data show that the relationship between negative schizotypy and social functioning is at least partially attributable to deficits in affective empathy.

Abstract: It has been suggested that despite explicit recognition difficulties, implicit processing of facial expressions may be preserved in older adulthood. To directly test this possibility, the authors used facial electromyography to assess older (N=40) and young (N=46) adults' mimicry responses to angry and happy facial expressions, which were presented subliminally via a backward masking technique. The results indicated that despite not consciously perceiving the facial emotion stimuli, both groups mimicked the angry and happy facial expressions. Implications for emotion recognition difficulties in late adulthood are discussed.

Abstract: Previous research has identified “the age–prospective memory paradox”—that adult ageing results in reliably poorer performance on laboratory-based tasks of prospective memory (PM), but improved performance on such tasks carried out in real-life settings. We hypothesized that even in their everyday environment, older adults might be worse at PM tasks that are triggered during an experimenter-generated ongoing activity. The present study used a task that captured the key features of the classic laboratory paradigm, but which was completed in a setting that met key criteria to be considered naturalistic. In their everyday setting, participants’ PM was assessed, with the cue to remember occurring either (a) during their day-to-day activities, or (b) during an experimenter-generated ongoing task. The results confirmed previous naturalistic findings, in showing that older adults ( n = 28) exhibited better PM than their younger counterparts ( n = 65) when prompted during their everyday activities. However, older adults were also then subsequently less likely to show effective PM during experimenter-generated ongoing activity. Reproducing the paradox within a single dataset, these data indicate that older adults can effectively act on intentions during everyday activities, but have difficulty in prospective remembering during experimenter-generated ongoing tasks.

Abstract: We investigated young-old differences in emotion recognition using music and face stimuli and tested explanatory hypotheses regarding older adults' typically worse emotion recognition. In Experiment 1, young and older adults labeled emotions in an established set of faces, and in classical piano stimuli that we pilot-tested on other young and older adults. Older adults were worse at detecting anger, sadness, fear, and happiness in music. Performance on the music and face emotion tasks was not correlated for either age group. Because musical expressions of fear were not equated for age groups in the pilot study of Experiment 1, we conducted a second experiment in which we created a novel set of music stimuli that included more accessible musical styles, and which we again pilot-tested on young and older adults. In this pilot study, all musical emotions were identified similarly by young and older adults. In Experiment 2, participants also made age estimations in another set of faces to examine whether potential relations between the face and music emotion tasks would be shared with the age estimation task. Older adults did worse in each of the tasks, and had specific difficulty recognizing happy, sad, peaceful, angry, and fearful music clips. Older adults' difficulties in each of the 3 tasks-music emotion, face emotion, and face age-were not correlated with each other. General cognitive decline did not appear to explain our results as increasing age predicted emotion performance even after fluid IQ was controlled for within the older adult group.

Abstract: This systematic review and meta-analysis quantifies the magnitude and breadth of age-related differences in trust. Thirty-eight independent data sets met criteria for inclusion. Overall, there was a moderate effect of age group on trust (g = 0.22), whereby older adults were more trusting than young adults. Three additional meta-analyses assessed age-related differences in trust in response to varying degrees of trustworthiness. This revealed that older adults were more trusting than young adults in response to neutral (g = 0.31) and negative (g = 0.33), but not positive (g = 0.15), indicators of trustworthiness. The effect of age group on trust in response to positive and neutral cues was moderated by type of trust (financial vs. nonfinancial) and type of responding (self-report vs. behavioral). Older adults were more trusting than young adults in response to positive and neutral indicators of trustworthiness when trust was expressed nonfinancially, but not financially. There was also an age-related increase in self-reported, but not behavioral, trust in response to neutral cues. Older adults were more trusting than young adults in response to negative indicators of trustworthiness regardless of the type of trust or type of responding. The reliability of information about trustworthiness did not moderate any of the effects of age group on trust. Implications of these findings and directions for future research are discussed.

Abstract: Although the experience of self-conscious emotion is critical for motivating social behavior, no study to date has tested whether this type of emotional responding is disrupted in the context of schizophrenia. In the present study we compared the responses of 27 participants with schizophrenia and 28 controls to a loud acoustic stimulus a manipulation that has previously been shown to elicit a defensive behavioral response, followed by the self-conscious emotional response of embarrassment. The results indicated that there were no group differences in the magnitude of the defensive response, as indexed by both behavioral and physiological assessment. Further, although the acoustic paradigm was effective in eliciting embarrassment (as evidenced by positive associations between defensive reaction and subsequent self-conscious emotional behavior), no group effects were observed in the magnitude of the embarrassment response. However, since greater embarrassment in the schizophrenia group was associated with better social functioning and lower negative affect, these data are broadly consistent with theoretical models that regard the experience of self-conscious emotion as indicative of greater interpersonal connectedness and enhanced social functioning.

Abstract: The aim of the current study was to establish the reliability and validity of one of the most used schema questionnaires, Young Schema Questionnaire Short Form Version 3 (YSQ-S3) in older adults. 104 participants aged 60-84 years were recruited. They were administered a battery of questionnaires, including the YSQ-S3, Young-Atkinson Mode Inventory (YAMI), Germans (Personality) Screener, the Geriatric Depression Scale (GDS), The Geriatric Anxiety Inventory (GAI) and the Basic Psychological Needs Scale (BPNS). The YSQ-S3 was completed a second time by 83 participants a median of 12 days later. Satisfactory internal consistency reliability was found for 13 of the 18 early maladaptive schemas (EMS) of the YSQ-S3. Test-retest reliability was satisfactory for 17 of 18 EMS. Convergent validity was evident from significant correlations between the EMS of the YSQ-S3 and the vulnerable child and angry child schema modes from the YAMI. Congruent validity was evident from correlations of the majority of the EMS with the GDS, the GAI, German's (Personality) Screener and the BPNS measure. By and large the YSQ-S3 demonstrates internal and test re-test reliability in as well as congruent and convergent validity, in older adults. This suggests the YSQ-S3 may be of use in work establishing the utility of schema therapy in this population, and that schema therapy with older people warrants further exploration. Notwithstanding this some re-development of some EMS items appears to be required for the YSQ-S3 to be more relevant to older people.

Abstract: It has been suggested that an age-related positivity effect may only occur in the context of explicit information processing, but it is unclear whether this bias extends to the processing of rapid facial reactions. In addition, most studies that have looked for evidence of age-related implicit positivity have used attentional (as opposed to sensory) unawareness paradigms, or used broad-based indicators of attentional awareness that do not speak to the nature of the affective response. In the present study, younger and older adults were therefore asked to view non-facial images presented supraliminally (i.e., consciously) as well as outside of sensory awareness (i.e., subliminally) while their facial reactions were indexed using electromyography. The results indicated that both younger and older adults exhibited rapid facial reactions congruent with the emotional valence of non-facial images in both supraliminal and subliminal conditions. Relative to young, older adults did not respond with greater zygomaticus (cheek) activity to positive stimuli or reduced corrugator (brow) activity to negative stimuli in either condition. These data show that rapid facial reactions to emotional stimuli are intact in late adulthood, even in response to stimuli that activate more automatic and implicit forms of emotion processing. However, there is no evidence for any age-related positivity bias in these behavioral responses.

Abstract: Episodic future thinking (EFT), the ability to project into the future to “preexperience” an event, and prospective memory (PM), remembering to perform an intended action, are both ex les of future-oriented cognition. Recently it has been suggested that EFT might contribute to PM performance but to date few studies have examined the relationship between these two capacities. The aim of the present study was to investigate the nature and specificity of this relationship, as well as whether it varies with age. Participants were 125 younger and 125 older adults who completed measures of EFT and PM. Significant, positive correlations between EFT and PM were identified in both age groups. Furthermore, EFT ability accounted for significant unique variance in the young adults, suggesting that it may make a specific contribution to PM function. Within the older adult group, EFT did not uniquely contribute to PM, possibly indicating a reduced capacity to utilize EFT, or the use of compensatory strategies. This study is the first to provide systematic evidence for an association between variation in EFT and PM abilities in both younger and older adulthood and shows that the nature of this association varies as a function of age.

Abstract: Changes in emotional and social behavior are considered to be amongst the most common and debilitating consequences of schizophrenia. However, little is known of the effects of schizophrenia on alexithymia, which refers to impairment in aspects of understanding emotions. In the current study, participants with schizophrenia (n = 29) and nonclinical controls (n = 30) completed self-report and performance-based measures of this construct, in addition to measures of cognitive functioning, clinical symptomatology, and negative affect. The results indicated that in iduals with schizophrenia showed increased alexithymia as indexed by the performance task, with these difficulties related to cognitive functioning, and the specific clinical symptom of alogia. However, although the correlation between self-reported alexithymia and negative affect in the schizophrenia group was congruent with prior empirical research and theory, there were no group differences in perceived levels of alexithymia. It is suggested that alexithymia may not be affected per se in schizophrenia (as indicated by the lack of group differences on the self-report measure of this construct), but that schizophrenia-related difficulties do emerge in contexts where cognitive demands are incremented.

Abstract: To determine whether obesity, estimated according to body mass index (BMI), waist circumference, and body fat and abdominal fat assessed using dual-energy X-ray absorptiometry (DEXA), was associated with cognitive performance. Cross-sectional. Community based. In iduals aged 74-94 (N = 406). BMI, waist circumference, body fat, and abdominal fat were assessed using DEXA. Cognitive performance was assessed using a comprehensive neuropsychological battery. When categorized using BMI, overweight in iduals had higher global cognitive function and executive function scores than normal-weight in iduals. This relationship did not differ according to sex. When categorized according to DEXA, there were no relationships between body fat and cognitive function in the whole group, but women in the middle and highest tertiles of DEXA body fat had better executive function than those in the lowest tertile. Men in the middle tertile of DEXA body fat had significantly better executive function and memory than those in the lowest tertile. BMI had greater power to predict executive function than DEXA body fat. No significant associations were found between cognition and estimates of abdominal adiposity. This study found an association between being overweight and better executive function in elderly adults this association was stronger for the simpler BMI than the more-elaborate DEXA measures.

Abstract: Older adults report being more trusting than young adults, and this may be particularly evident in close social relationships. This is beneficial for well-being when trust is reciprocated, but detrimental when trust is exploited. In a repeated trust game, young (n = 35) and older adults (n = 33) invested real money over repeated interactions with trustees of varying social distances (close, neutral, distant) and trustworthiness (trustworthy, untrustworthy). Young and older adults were equally proficient at learning to integrate congruent information so that by the end of the task they were investing most with close trustees who reciprocate often and least with distant trustees who rarely reciprocate. Averaged across time, however, older adults were more likely than young adults to invest with all trustees, with the one exception of close trustees who reciprocate often. In addition, among older adults, higher intelligence was correlated with larger investments with the most trustworthy trustees, and better subjective financial well-being was associated with increased investing in the most untrustworthy trustees. Although both age groups demonstrated a confirmation bias by integrating preexisting beliefs with ongoing behavior in order to determine trustworthiness, this effect was most consistent among the young adults. We discuss the potential danger, particularly for finances, when older adults discount information pertaining to trustworthiness and/or untrustworthiness. (PsycINFO Database Record

Abstract: Age-related difficulties in understanding basic emotional signals are now well established, but less clear is how aging affects theory of mind (ToM), which refers to the understanding of more complex emotions and mental states. A meta-analysis of 23 datasets involving 1462 (790 younger and 672 older) participants was conducted in which six basic types of ToM task were identified (Stories, Eyes, Videos, False belief-video, False belief-other, and Faux pas). Each ToM task was also categorized according to domain (affective, cognitive, or mixed) and modality (verbal, visual-static, visual-dynamic, verbal and visual-static, or verbal and visual-dynamic). Overall, collapsed across all types of task, older adults were found to perform more poorly than younger adults, with the degree of ToM difficulty they experienced moderate in magnitude (r = -.41). The results also provide evidence for increased ToM difficulties in late adulthood regardless of specific task parameters, with deficits evident across all task types, domains, and modalities. With few exceptions, age deficits for ToM tasks were larger in magnitude compared with matched control tasks. These data have implications for our understanding of mental state attribution processes in late adulthood, suggesting that ToM difficulties are not simply secondary to non-ToM related task demands.

Abstract: There is considerable literature showing that opiate use is associated with a range of neurocognitive deficits, including deficits in executive control and episodic memory. However, no study to date has assessed whether these neurocognitive difficulties extend to the ability to mentally time travel into one's personal future. This is a surprising omission given that executive control and episodic memory are considered to be critical for episodic foresight. In addition, opiate-related brain changes have been identified in the neural regions that underlie the capacity for episodic foresight. In the present study, we assessed how episodic foresight is affected in the context of chronic opiate use, as well as the degree to which any deficits are related to difficulties with executive control and episodic memory. Forty-eight long-term heroin users enrolled in an opiate substitution program and 48 controls were tested. The results showed that, relative to controls, the clinical group exhibited significant impairment in episodic foresight but not episodic memory (as indexed by an adapted version of the Autobiographical Interview). For executive function, the clinical group was impaired on only one of three measures (Inhibition). These data provide important preliminary evidence that episodic foresight might be particularly susceptible to the neurocognitive effects of opiate use, as the difficulties identified were not secondary to more general executive control or episodic memory impairment. Because a number of widely used relapse prevention protocols require the ability to mentally project into the future, these data have potentially important practical implications in relation to the treatment of substance dependence disorders.

Abstract: Both cognitive and affective empathy are regarded as essential prerequisites for successful social functioning, and recent studies have suggested that cognitive, but not affective, empathy may be adversely affected as a consequence of normal adult aging. This decline in cognitive empathy is of concern, as older adults are particularly susceptible to the negative physical and mental health consequences of loneliness and social isolation. The present study compared younger (N = 80) and older (N = 49) adults on measures of cognitive empathy, affective empathy, and social functioning. Whilst older adults' self-reported and performance-based cognitive empathy was significantly reduced relative to younger adults, there were no age-related differences in affective empathy. Older adults also reported involvement in significantly fewer social activities than younger adults, and cognitive empathy functioned as a partial mediator of this relationship. These findings are consistent with theoretical models that regard cognitive empathy as an essential prerequisite for good interpersonal functioning. However, the cross-sectional nature of the study leaves open the question of causality for future studies.

Abstract: Older adults have a reduced capacity to take the perspective of another, and it has been suggested that disinhibition may be one mechanism contributing to this difficulty. To test this possibility, we had behavioral measures that were sensitive to inhibitory failure and to theory of mind (ToM) administered to younger and older adults. One of the measures of ToM directly manipulated inhibitory demands, involving either high or low levels of self-perspective inhibition. The results indicated that older adults were selectively impaired on the high-inhibition condition. Further, of the various aspects of cognitive functioning that we assessed, including memory, mental flexibility, and cognitive speed, only cognitive disinhibition mediated age-related differences in ToM. These results suggest that inhibitory control is an important mediator of ToM in late adulthood.

Abstract: Efficient intention formation might improve prospective memory by reducing the need for resource-demanding strategic processes during the delayed performance interval. The present study set out to test this assumption and provides the first empirical assessment of whether imagining a future action improves prospective memory performance equivalently at different stages of the adult lifespan. Thus, younger ( n = 40) and older ( n = 40) adults were asked to complete the Dresden Breakfast Task, which required them to prepare breakfast in accordance with a set of rules and time restrictions. All participants began by generating a plan for later enactment however, after making this plan, half of the participants were required to imagine themselves completing the task in the future (future thinking condition), while the other half received standard instructions (control condition). As expected, overall younger adults outperformed older adults. Moreover, both older and younger adults benefited equally from future thinking instructions, as reflected in a higher proportion of prospective memory responses and more accurate plan execution. Thus, for both younger and older adults, imagining the specific visual–spatial context in which an intention will later be executed may serve as an easy-to-implement strategy that enhances prospective memory function in everyday life.

Abstract: To examine the psychometric properties of the Emotion Regulation Questionnaire (ERQ) among a s le of older community-dwelling males and females and to also assess gender differences in the association between emotion regulation and positive and negative affect. The ERQ and the Positive and Negative Affect Schedule-10 were administered to 252 older adults (age range 60-89 years 48.4% female). The two ERQ subscales, reappraisal and suppression, were internally consistent. Reappraisal was positively correlated with positive affect among both genders, and negatively correlated with negative affect among older women only. Suppression was positively correlated with negative affect among older men only and unrelated to positive affect for both genders. Confirmatory factor analysis showed that a two-factor solution fits the data from both genders. The results provide evidence to support the ERQ for use with older adults, while identifying clinically important gender differences in the associations between emotion regulation tendencies and affect in older age. Reliability and validity of the 10-item Emotion Regulation Questionnaire is supported for use among older adults. Suppression positively correlated with negative affect among older men but not older women. Reappraisal negatively correlated with negative affect among older women but not men. The current data from a community-dwelling population may not generalize to older adults with clinical disorders.

Abstract: The present study explored own-age biases in deception detection, investigating whether in iduals were more likely to trust those in their own-age group. Younger and older participants were asked to detect deceit from videos of younger and older speakers, rating their confidence in each decision. Older participants showed an own-age bias: they were more likely to think that deceptive speakers of their own age, relative to younger speakers, were telling the truth. Older participants were also more confident in their judgements of own-age, relative to other-age, speakers. There were no own-age biases for younger participants. In a subsequent (apparently unrelated) task, participants were asked to rate the trustworthiness of the speakers. Both age groups of participants trusted younger speakers who had previously told the truth more compared to those who had lied. This effect was not found for older speakers. These findings are considered in relation to the in-group/out-group model of social cognition and common stereotypical beliefs held about younger and older adults.

Abstract: The relevance of schema theory to psychopathology, in particular personality disorder, in younger adults is established. Investigations into the relevance of schema theory to older adults, however, is highly limited. To consider the relationship of schema modes to psychopathology in older adults and establish whether maladaptive schema modes are associated with unmet needs and that this relationship is mediated by the healthy adult mode of responding in this population. One hundred and four older adults were recruited from an established database. Participants completed questionnaires assessing psychopathology, schema modes (YAMI: Young-Atkinson Mode Inventory) and basic psychological needs (BPNS: Basic Psychological Needs Scale – autonomy, competence and relatedness). Ninety-four responses were included after applying exclusion criteria. The healthy adult schema mode was found to be associated with reduced psychopathology, and maladaptive child modes (angry and vulnerable child) to increased psychopathology. The healthy adult schema mode mediated the relationship between maladaptive child modes and needs satisfaction. As predicted by schema theory, the presence of one of the maladaptive child modes makes it difficult for an older in idual to have their needs met, but the presence of healthy adult mode works to support this process.

Abstract: Previous research has shown that empathy for pain is disrupted at the neural level in people with schizophrenia. However, many of these studies have failed to assess key background contextual variables that have previously been linked to neurophysiological responding. Moreover, no study to date has examined the potential influence of schizotypal characteristics on neurophysiological responding in non-clinical in iduals. People with schizophrenia (N = 17) were compared to demographically matched controls (N = 19) on an event-related potential (ERP) empathy for pain paradigm. The control group also completed a measure of schizotypal personality traits. People with schizophrenia exhibited atypical neural responding at early, emotion-sharing (frontal N110), and late, cognitive (central late positive potential [LPP]) processing stages of pain empathy, relative to controls. In the control group, positive schizotypy traits were significantly negatively related to reduced ERP litude in the late, cognitive (central LPP) processing stage of empathy. These data cross-validate previous studies that have shown that schizophrenia is associated with atypicalities in bottom-up automatic resonance processes that likely contribute to empathic and socio-emotional processing deficits, and indicate that these findings cannot be easily attributed to background contextual differences between the two groups. The results also point to a potential relationship between positive schizotypal characteristics and neurophysiological responding. Implications for simulation theories of empathy and social functioning in schizophrenia are discussed. Empathic processing has been consistently linked to well-being and mental health in many groups, including people with schizophrenia. Previous research has shown that, relative to controls, people with schizophrenia exhibit abnormalities in their neurophysiological empathic response, but in these prior studies, the two groups also differed in a number of potentially important background contextual variables. The current study shows that, when closely matched on background contextual variables, abnormal neural responding is still evident. These data suggest that empathy for pain is disrupted at the neurophysiological level in schizophrenia.

Abstract: The current study investigates the neural substrates of facial expression mimicry by assessing in iduals with right and left lateralised frontal cortical lesions. Electromyography was used to measure spontaneous changes in electrical activity over the corrugator supercilii (brow) and zygomaticus major (cheek) muscle regions in response to happy and angry facial expressions. In iduals with right (n=4) and left (n=5) frontal cortical lesions and demographically matched controls (n=9) were compared. It was shown that while all three groups mimic happy facial expressions, only controls and in iduals with left frontal lesions mimic angry expressions. These data are consistent with evidence for right frontal cortical specialisation for the processing of anger.

Abstract: In a series of 1-shot economic trust games in which participants could make real monetary profits, but also risked losing money, 2 studies compared young and older adults' trust (amount invested with trustees) and trustworthiness (amount returned to investors by trustees). In Study 1, young (n = 35) and older (n = 32) participants acted as investors, and the age of simulated trustees (young, older) was manipulated. In Study 2, young (n = 61) and older (n = 67) participants acted in real life as both investors and trustees. They completed 2 face-to-face trust games with same- and other-age partners, and 3 anonymous trust games with same-, other-, and unknown-age partners. Study 1 found that young and older participants rate older trustees as appearing more trustworthy than young trustees, but neither group invest more with older than young trustees. Rather, older participants were more likely than young participants to invest money averaged across trustee age. In Study 2, there were no age-related differences in trust, but older adults were more trustworthy than young adults in anonymous games with same- and unknown-age partners. It was also found that young adults demonstrate greater reputational concerns than older adults by reciprocating more trust when face-to-face than anonymous. We discuss the complex influences of age on trust game investing and reciprocation, as well as the implications for older adults' wellbeing and financial security.

Abstract: Although older adults have difficulty recognizing all facial emotions, they have particular difficulty decoding expressions of anger. Since disruption of facial mimicry impairs emotion recognition, electromyography of the corrugator supercilii (i.e., brow) muscle region was used to test whether there are age differences in anger mimicry. Associations between mimicry and emotion recognition were also assessed. The results indicated that although there were no age differences in anger mimicry, older (but not young) adults' corrugator responses to angry expressions were associated with reduced anger recognition. Implications for understanding emotion recognition difficulties in older adulthood are discussed.

Abstract: Trust is a particularly under-studied aspect of social relationships in older age. In the current study, young (n = 35) and older adults (n = 35) completed a series of one-shot social economic trust games in which they invested real money with trustees. There were potential gains with each investment and also a risk of losing everything if the trustee was untrustworthy. The reputation and facial appearance of each trustee were manipulated to make them appear more or less trustworthy. Results revealed that young and older adults invest more money with trustees whose facial appearance and reputation indicate that they are trustworthy rather than untrustworthy. However, older adults were more likely than young to invest with trustees who had a reputation for being untrustworthy. We discuss whether age-related differences in responding to negative information may account for an age-related increase in trust, particularly when trusting someone with a reputation for being uncooperative.

Abstract: Emotional stimuli, such as facial expressions, reliably evoke rapid, spontaneous and covert facial reactions in the perceiver that reflect the affective valence of the observed stimulus. These physiological reactions have been linked to a variety of social cognitive processes known to be disrupted in schizophrenia, such as emotion recognition and affective empathy. Moreover, in iduals with schizophrenia exhibit atypical rapid facial reactions when observing emotional expressions. The current study aimed to determine if the disruption in schizophrenia is specific to facial expressions, or instead reflects more generalised emotional or motor impairments in the elicitation of this rapid facial response. Here we quantified activity in the corrugator supercilii and zygomaticus major muscle regions using electromyography while in iduals with schizophrenia (n = 24) and controls (n = 21) viewed images of facial and non-facial emotional stimuli. The results indicate that schizophrenia is marked by a disruption in rapid facial responding to facial expressions, but intact responding to non-facial emotional stimuli. This dissociation between the processing of facial and non-facial emotional stimuli points to the need for a greater understanding of the degree to which facial emotion processing impairments contribute to disruptions in mimetic responding in this population.

Abstract: The capacity to imagine oneself experiencing future events has important implications for effective daily living but investigation of this ability in autism spectrum disorder (ASD) is limited. This study investigated future thinking in 30 children with high functioning ASD (IQ > 85) and 30 typically developing children. They completed the Adapted Autobiographical Interview, a measure which required participants to describe personal past events (indexing episodic memory) and plausible future events (indexing episodic future thinking). The results showed that there are ASD-related deficits in future thinking, and also provided preliminary evidence regarding cognitive mechanisms that may (and may not) contribute to these difficulties. The theoretical and practical implications of these results are discussed.

Abstract: Despite recognition of the increasing influence of emotion on decision making with age, there are few studies that have assessed older adults' financial choices in a socioemotional context. Thus, social economic decision making between same- versus other-aged partners was assessed. Young (n = 35) and older (n = 34) adults participated in two Ultimatum Games. In the first, they proposed isions of money between themselves and future young and older participants. In the second, they accepted or rejected fair and unfair isions of money proposed by past young and older participants. Lastly, participants reported their anger in response to the offers that were proposed to them in the second game. In the first game, older participants ided the money more generously than did young participants. In the second game, young, but not older, participants rejected more unfair offers proposed by young relative to older adults. However, both participant age groups reported being angrier at unfair offers proposed by young adults compared with when receiving the same offer from an older adult. These findings are discussed in the context of evidence for improved anger regulation and increased prosocial behavior with age.

Abstract: Episodic foresight refers to the capacity to mentally travel forward in time and has been linked to a wide variety of important functional behaviours. Evidence has recently emerged that chronic opiate use is associated with deficits in this critical capacity and that these difficulties are not simply a secondary consequence of broader cognitive dysfunction. The current study aimed to better understand the circumstances in which chronic opiate users might be expected to have problems with episodic foresight, by addressing whether deficits reflect compromised scene construction, self-projection, or narrative ability. Thirty-five chronic opiate users and 35 demographically matched controls completed an imagination task in which they were instructed to imagine and provide descriptions of an atemporal event, a plausible, self-relevant future event, as well as complete a narrative task. These three imagination conditions systematically varied in their demands on scene construction, self-projection, and narrative ability. Consistent with prior literature, chronic opiate users exhibited reduced capacity for episodic foresight relative to controls. However, this study was the first to show that these difficulties were independent of capacity for scene construction and narration. Instead, a specific impairment in self-projection into the future appears to contribute to the problems with episodic foresight seen in this clinical group. Deficits in self-projection into the future may have important implications in therapeutic environments given that many relapse prevention strategies rely heavily on the ability to project oneself into an unfamiliar future, free of problem substance use. A reduced capacity for episodic foresight highlights the importance of refining current relapse prevention protocols that place significant demands for mental time travel into the future. Psychosocial treatments should focus on the attainment of more immediate or short-term goals. It is difficult to delineate the effects of specific substances given long-standing drug use history common to chronic opiate users. Conclusions relating to neurological functioning are speculative given the absence of neuroimaging data.

Abstract: Electromyographic (EMG) research suggests that implicit mimicry of happy facial expressions remains intact with age. However, age-related differences in EMG responses to enjoyment and nonenjoyment smiles have not been explored. The present study assessed younger and older adults' orbicularis oculi (O.oculi eye) and zygomaticus major (Z.major cheek) reactions to images of in iduals displaying enjoyment and nonenjoyment smiles. Both age groups mimicked displays of enjoyment smiles, and there were no age differences in O.oculi and Z.major activity to these expressions. However, compared with younger participants, older adults showed extended O.oculi activity to nonenjoyment smiles. In an explicit ratings task, older adults were also more likely than younger participants to attribute feelings of happiness to in iduals displaying both nonenjoyment and enjoyment smiles. However, participants' ratings of the happiness expressed in images of enjoyment and nonenjoyment smiles were independent of their O.oculi responding to these expressions, suggesting that mimicry and emotion recognition may reflect separate processes. Potential mechanisms underlying these findings, as well as implications for social affiliation in older adulthood, are considered.

Abstract: Extreme weather events can pervasively influence ecosystems. Observations in lakes indicate that severe storms in particular can have pronounced ecosystem-scale consequences, but the underlying mechanisms have not been rigorously assessed in experiments. One major effect of storms on lakes is the redistribution of mineral resources and plankton communities as a result of abrupt thermocline deepening. We aimed at elucidating the importance of this effect by mimicking in replicated large enclosures (each 9 m in diameter, ca. 20 m deep, ca. 1300 m

Abstract: This study investigated whether differences in the type of strategy used, or age-related differences in intensity of facial reactivity, might contribute to preserved emotion regulation ability in older adults. Young (n = 35) and older (n = 33) adults were instructed to regulate their emotion to positive and negative pictures under 3 conditions (watch, expressive suppression, cognitive 'detached' reappraisal). Participants were objectively monitored using facial electromyography (EMG) and assessed on memory performance. Both age groups were effectively, and equivalently, able to reduce their facial expressions. In relation to facial reactivity, the percentage increase of older adults' facial muscle EMG activity in the watch condition was significantly reduced relative to young adults. Recall of pictures following regulation was similar to the watch condition, and there was no difference in memory performance between the 2 regulation strategies for both groups. These findings do not support the proposal that the type of strategy used explains preserved emotion regulation ability in older adults. Coupled with the lack of memory costs following regulation, these data instead are more consistent with the suggestion that older adults may retain emotion regulation capacity partly because they exhibit less facial reactivity to begin with.

Abstract: Whilst alexithymia has been consistently linked to somatization, two prominent theoretical models lead to opposite predictions as to which of two proposed typologies of alexithymia will be particularly associated with somatic symptom reporting. In the present study, participants were recruited from a cross-section of the general adult population (n=301), and asked to complete a battery of self-report questionnaires which assessed alexithymia, somatization and negative affect. Collapsed across the whole s le, specific facets of alexithymia (enhanced fantasy life and difficulty identifying emotions) were significantly associated with somatization, and these pathways were perfectly mediated by negative affectivity. Further, type II alexithymia (impairment in the cognitive but not the affective dimension of alexithymia) was more predictive of somatization relative to type I alexithymia (impairment in both the cognitive and affective dimensions of alexithymia) and non-alexithymia (unimpaired in the cognitive and affective dimensions of alexithymia). The theoretical and clinical implications of these results are discussed.

Abstract: Increasing emphasis has been placed on the role of socioemotional functioning in models of obsessive-compulsive disorder (OCD). The present study investigated whether OCD symptoms were associated with capacity for theory of mind (ToM) and basic affect recognition. Non-clinical volunteers (N=204) completed self report measures of OCD and general psychopathology, in addition to behavioral measures of ToM and affect recognition. The results indicated that higher OCD symptoms were associated with reduced ToM, as well as reduced accuracy decoding the specific emotion of disgust. Importantly, these relationships could not be attributed to other, more general features of psychopathology. The findings of the current study therefore further our understanding of how the processing and interpretation of social and emotional information is affected in the context of OCD symptomatology, and are discussed in relation to neuropsychological models of OCD.

Abstract: Older adults exhibit poorer mental health literacy than younger adults, including less accuracy at identifying symptoms of mental disorders, and endorsing fewer sources of treatment for a mental disorder. The current study's intention was to determine if the executive component of cognition is associated with mental health literacy in older adults, when controlling for other established predictors (sex, age, education, and proximity to someone with a mental disorder). The s le included 85 cognitively healthy adults aged 60 and over. Participants completed the Mini-Addenbrooke's Cognitive Examination III, the Trail Making Test, a Phonemic Verbal Fluency Test, and the Mental Health Literacy Scale. A multiple regression indicated that age and mental health proximity significantly and uniquely predicted total mental health literacy (Age: β = -0.22, t = -2.04, p < 0.05 Proximity: β = 0.31, t = 2.78, p < 0.01). Older age predicted poorer PTSD mental health literacy (β = -0.31, t = -2.90, p < 0.01). In neurologically healthy older adults, level of executive function did not contribute to mental health literacy. Older adults in closer proximity to someone with a mental disorder were more likely to have better mental health literacy, a finding that has the potential to inform mental health education and promotion strategies in this population.

Abstract: Episodic future thinking refers to mentally traveling forward in time to preexperience an event, and emerging research suggests that this is more difficult for older adults. The current study was designed to better understand the effect of aging on separate component processes of age differences in episodic future thinking. Young (n = 24) and older (n = 25) adults were asked to construct a) atemporal scenarios, b) future scenarios, and c) a narrative that involved navigation. Each of these conditions assesses the capacity to construct and describe a scene, but only the future scenario requires a subjective sense of self in time (autonoetic consciousness). The composite measure of performance showed that relative to young adults, older adults have substantially reduced capacity for all three types of construction, suggesting that age-related difficulty imagining future episodic events may reflect a more general cognitive decline with age. In addition, older adults were worse at imagining future experiences than atemporal experiences, indicating limited capacity for autonoetic consciousness. Further, this difference between imagining atemporal and future experiences was not as evident among younger adults. These deficits in episodic future thinking have implications for the daily lives of older adults in terms of anticipating and planning for the future.
