Abstract: Most experiments on conformity have been conducted in relation to judgments of physical reality surprisingly few papers have experimentally examined the influence of group norms on social issues with a moral component. In response to this, participants were told that they were either in a minority or in a majority relative to their university group in terms of their attitudes toward recognition of gay couples in law (Expt 1: N = 205) and a government apology to Aborigines (Expt 2: N = 110). In both experiments, it was found that participants who had a weak moral basis for their attitude conformed to the group norm on private behaviours. In contrast, those who had a strong moral basis for their attitude showed non-conformity on private behaviours and counter-conformity on public behaviours. Incidences of non-conformity and counter-conformity are discussed with reference to theory and research on normative influence.

Abstract: Data from prior health scares suggest that an avian influenza outbreak will impact on people's intention to donate blood however, research exploring this is scarce. Using an augmented theory of planned behavior (TPB), incorporating threat perceptions alongside the rational decision-making components of the TPB, the current study sought to identify predictors of blood donors' intentions to donate during two phases of an avian influenza outbreak. Blood donors (n = 172) completed an on-line survey assessing the standard TPB predictors as well as measures of threat perceptions from the health belief model (i.e., perceived susceptibility and severity). Path analyses examined the utility of the augmented TPB to predict donors' intentions to donate during a low- and high-risk phase of an avian influenza outbreak. In both phases, the model provided a good fit to the data explaining 69% (low risk) and 72% (high risk) of the variance in intentions. Attitude, subjective norm, and perceived susceptibility significantly predicted donor intentions in both phases. Within the low-risk phase, sex was an additional significant predictor of intention, while in the high-risk phase, perceived behavioral control was significantly related to intentions. An augmented TPB model can be used to predict donors' intentions to donate blood in a low-risk and a high-risk phase of an outbreak of avian influenza. As such, the results provide important insights into donors' decision-making that can be used by blood agencies to maintain the blood supply in the context of an avian influenza outbreak.

Abstract: Rape cases have a disproportionately high attrition rate and low conviction rate compared to other criminal offenses. Evaluations of a rape complainant’s credibility often determine whether a case progresses through the criminal justice system. Even though emotional demeanor is not related to witness honesty or accuracy, distressed rape complainants are perceived to be more credible than complainants who present with controlled affect. To understand the extent and robustness of the influence of emotional demeanor on credibility judgments of female adult rape complainants, we conducted a systematic review, meta-analysis and p-curve analysis of the experimental simulated decision-making literature on the influence of complainant emotional demeanor on complainant credibility. The meta-analysis included 20 studies with participants who were criminal justice professionals (e.g., police officers and judges), community members, and mock jurors (N = 3128). Results suggest that distressed demeanor significantly increased perceptions of complainant credibility, with a small to moderate effect size estimate. Importantly, the results of p-curve analysis suggest that reporting bias is not a likely explanation for the effect of emotional demeanor on rape complainant credibility. S le type (whether perceivers were criminal justice professionals or prospective jurors) and stimulus modality (whether perceivers read about or watched the complainant recount the alleged rape) were not found to moderate the effect size estimate. These results suggest that effective methods of reducing reliance on emotional demeanor to make credibility judgments about rape complainants should be investigated to make credibility assessments fairer and more accurate.

Abstract: Research has consistently shown that jurors are influenced by multiple schemas in cases of alleged sexual assault, including offense stereotypes and victim stereotypes. These schemas appear to be organized in a hierarchy, as victim stereotypicality seems to matter most in acquaintance assaults (counter-stereotypical offense). However, despite numerous studies demonstrating the impact of defendant stereotypes on juror perceptions of guilt for other crimes, to date, the impact of stereotypes about defendants (perpetrators) in cases involving sexual violence have been overlooked. As such, the current research aimed to build on the existing hierarchical schema model by systematically examining the influence of perpetrator stereotypes. Following pilot work, mock jurors’ ( N = 163) read a rape scenario that varied in terms of offense stereotypicality (stereotypical, counter-stereotypical), victim stereotypicality (stereotypical, counter-stereotypical), and perpetrator stereotypicality (stereotypical, counter-stereotypical). Broadly consistent effects of offense stereotypicality and victim stereotypicality were observed across the outcome measures, such that the victim was perceived more positively and the perpetrator more negatively when the victim was described as being stereotypical and when the offense was described as stereotypical. However, contrary to past findings, the effect of victim stereotypicality did not differ as a function of offense stereotypicality. Furthermore, perpetrator stereotypicality did not influence perceptions in the stereotypical offense scenario. These findings suggest that contrary to the assertions of previous research, there is not a series of specific, in idual stereotypes that impact attributions of blame, rather, there may be one underlying schema about consent that influences perceptions. These findings have important implications for how we address the effect of juror-held schemas on attributions of blame in cases of sexual assault.

Abstract: Forensic science techniques are often used in criminal trials to infer the identity of theperpetrator of crime and jurors often find this evidence very persuasive. Unfortunately, two of the leading causes of wrongful convictions are forensic science testing errors and false or misleading forensic testimony (Saks & Koehler, 2005). Therefore, it is important to understand jurors pre- existing beliefs about forensic science, as these beliefs may impact how they evaluate forensic evidence in the courtroom. In this study, we examine people’s perceptions of the likelihood of error and human judgment involved at each stage of the forensic science process (i.e., collection, storage, testing, analysis, reporting, and presenting). In addition, we examine peoples’ perceptions of the accuracy of — and human judgment involved in — 16 different forensic techniques. We find that, in contrast to what would be expected by the CSI effect literature, participants believed that the process of forensic science involved considerable human judgment and was relatively error-prone. In addition, participants had wide-ranging beliefs about the accuracy of various forensic techniques, ranging from 65.18% (document analysis) up to 89.95% (DNA). For some forensic techniques, estimates were lower than that found in experimental proficiency studies, suggesting that our participants are more skeptical of certain forensic evidence than they need to be. Keywords: Forensic science, forensic evidence, accuracy, error rate, CSI effect.

Abstract: Jurors rely on a range of schemas when evaluating allegations of rape and sexual assault. For ex le, they may be influenced by the prototypicality of the alleged offense, the stereotypicality of the victim, or gender-related stereotypes. These schemas have often been conflated however, making it difficult to determine the unique impact of each on jurors’ perceptions. To be able to effectively counter any schema-related misconceptions, we must first identify which beliefs are important and when. An experiment ( N = 420) examined the independent effects of offense prototypicality and victim stereotypicality on mock jurors’ perceptions. As expected, victim stereotypicality had a greater effect on judgments in the counter-prototypical (acquaintance) assault scenario than in the prototypical (stranger) assault scenario. When the complainant was described as being a counter-stereotypical victim in the acquaintance rape scenario, the defendant was seen as less likely to be guilty and evaluated more positively and the complainant less positively compared with when the complainant was described as being a stereotypical victim. Analysis of the qualitative data suggested a focus on different factors in reaching verdicts in the stranger and acquaintance rape scenarios. Results were interpreted as evidence that jurors “step down” through a hierarchy of schemas in their attempts to determine what happened in cases of rape and sexual assault.

Abstract: While deviance can foster innovation within groups, research does not always find beneficial effects. The current studies provide an information processing account of the influence of deviants in group decision-making. We predicted deviants would undermine decision confidence and promote greater elaboration when tasks were difficult. Study 1 manipulated the strength (systematic cue) and gender (heuristic cue) of a job applicant to investigate the effect of a deviant in a difficult task. As predicted, a deviant was associated with lowered confidence, greater elaboration, and higher decision quality, but also decreased group cohesion and task satisfaction. Study 2 investigated the effect of a deviant during a simple task and found the same decrease in group cohesion and task satisfaction, but this time with no increase in elaboration or improvement in decision outcome quality. Results indicate that deviance, when seen as justified, has the potential to reduce the occurrence of prejudice and produce fairer decision outcomes during decision-making.

Abstract: The present study investigated whether the impact of expert testimony was influenced by the congruency between the gender of the expert and the gender orientation of the case. Participants ( N = 62) read a trial transcript involving a price-fixing allegation in either a male or female oriented domain. Within the case, the gender of the expert was manipulated. As predicted, the impact of the expert (e.g. damage awards) was greater when the gender of the expert and domain of the case were congruent as opposed to incongruent. Results also indicated that the impact of gender-domain congruency was particularly pronounced following group discussion. In addition, there was evidence that this effect was mediated through participants’ evaluations of the expert witness.

Abstract: Forensic expert testimony is slowly starting to reflect the uncertain nature of forensic science, but the way experts should express the uncertainty of their decisions is under debate. Here we compare the likelihood model approach to a diagnostic approach — which provides information about performance and error rates — to determine which produces a more calibrated understanding and evaluation of the evidence. In Experiment 1 (N = 738), participants were more sensitive to differences in evidence strength when the evidence was expressed as diagnostic information than as a likelihood ratio, as predicted. In Experiment 2 (N = 499), however, when provided with both diagnostic information and a likelihood ratio, participants tended to discount the presence of the likelihood ratio in favour of the diagnostic information, which we did not predict. Together, these results suggest that providing fact-finders with diagnostic information might aid their understanding and evaluation of forensic evidence.

Abstract: Two studies investigated how both degree of identification and the in idual’s position within the group influence aspects of group loyalty. The authors considered ingroup position in terms of both the in idual’s current position within a group and expectations concerning the likelihood that one’s position might change in the future. Peripheral group members learned that their acceptance by other group members would improve in the future or that they could expect rejection by other group members. Various indices of group loyalty (ingroup homogeneity, motivation to work for the group, and evaluation of a motivated group member) showed that when group members anticipated future rejection, the lower the identification the less loyal they were. In contrast, those who expected future acceptance were more loyal (more motivated to work for the group) the lower their identification. Current group behavior depends on both intragroup future expectations and level of identification.

Abstract: It would seem important that jury instructions are clear and comprehensible to jurors if they are to effectively carry out their responsibility in criminal trials. Research suggests, however, that jurors may not fully understand instructions despite reporting high levels of comprehension. The current study (N = 33) surveyed jurors who had recently served on a jury to assess their level of comprehension and the factors that contributed to their decisions. It was found that a substantial proportion of jurors were mistaken about directions relating to beyond reasonable doubt and burden of proof. It also was found that higher levels of self-reported comprehension were associated with self-reported reliance on additional factors to arrive at a decision, and a more positive evaluation of the prosecutions’ case. Overall, although jurors report that they understand directions, they do not appear to use those directions in arriving at a decision. Subjective comprehension appears to be an important factor in understanding the effect of directions on jurors.

Abstract: Sharper Minds is a stepped care package designed by the researchers in collaboration with students and UQ Health Care providers to increase awareness and use of mental health prevention strategies among first year university students. The package was 'soft launched' in 2021, and this report presents findings from the pilot evaluation. The pilot adopted a non-randomised controlled design with 266 students (33% international students). Of these, 157 were in the INTERVENTION condition (students who participated in any aspect of the Sharper Minds package: app tracker or one of the short courses) and 109 were in the CONTROL condition (students who completed pre and post surveys only). Results showed a significantly greater benefit to students in the Intervention v Control on pre to post changes in % screening positive for mental health problems, and scores on measures of depression, wellbeing, and loneliness. Students in both conditions improved across semester on measures of anxiety, somatic symptoms, number of academic stressors and number of COVID-19 related stressors. The pilot also provided practical training for 15 Masters in Psychology students and 2 Masters in Dietetics students and research thesis projects for 1 Masters in Clinical Psychology student 21 Psychology Honours students and 5 Exercise Physiology Honours students.

Abstract: Te sexual assault victim "who comes to the attention of the authorities has her victimization measured against the current rape mythologies" (R v. Seaboyer, 1991). Tis is particularly troubling given that lay beliefs regarding the crime of sexual assault are at odds with the data documenting the circumstances surrounding actual rape. Research has consistently demonstrated that lay people (hence, jurors) will question the validity of a sexual assault claim and judge the victim more harshly, if the circumstances surrounding the assault and/or the characteristics and actions of the sexual assault complainant do not comport with people's expectations about the event. In this paper we report the results of a juror simulation that examines the impact of victim's postassault emotional demeanor on judgments, in the context of independent manipulations of gender stereotypicality and victim stereotypicality. Results revealed that the complainant's emotional display had a powerful impact on participants' judgments, with the claim viewed as more valid when the complainant was portrayed as tearful/upset as opposed to calm/controlled, but only when the complainant was portrayed as gender stereotypic.

Abstract: Two experiments provided support for the central hypothesis--derived from social identity/self-categorization theories--that attitudes would be most likely to predict behaviour when they were supported by a congruent in-group norm. In the first experiment, norm congruency and mode of behavioural decision-making (spontaneous or deliberative) were orthogonally manipulated in a between-subjects study of career choice in psychology. Participants exposed to an attitudinally congruent in-group norm towards their preferred career choice were more likely to display attitude-behaviour consistency than those exposed to an attitudinally inconsistent group norm, an effect that was evident under both spontaneous and deliberative decision-making conditions. Using a mock jury paradigm, Expt 2 replicated and extended the first experiment by including a manipulation of in-group salience. As predicted, participants exposed to an incongruent norm displayed greater attitude-behaviour inconsistency than those exposed to a congruent norm. Contrary to predictions, this effect did not vary as a function of group salience, nor did the effects of group norms for high and low salience participants vary as a function of mode of behavioural decision-making. However, there was evidence that perceived identification with the group moderated the influence of norms on attitude-behaviour consistency.

Abstract: Three studies systematically explored the relationship between social support and group identification in the context of how in iduals cope with stress. In Study 1, 101 participants took part in a simulated group task where they either received social support or not under conditions of either high or low demand. Social support was associated with higher group identification, and this mediated the effect of social support on more positive appraisals and task satisfaction. In Study 2, 83 participants were either made aware of their group membership or worked as in iduals on a group task under high or low demand. In this study, group membership salience was associated with greater perceived support, which was associated with greater group identification, and subsequently more positive primary and secondary appraisals, more problem-focused coping, and task satisfaction. Study 3 assessed the perceived social support and group identification reported by 71 volleyball team members before and after a game. Results were more consistent with the notion that support and identification were two concurrent perceptions associated with being in a group, rather than identification priming the recognition of support or support increasing identification.

Abstract: This report describes a pilot non-randomised controlled evaluation of the full Sharper Minds package in 2022. In total, 365 undergraduate students from across the university opted in to one of three conditions: Control (n=112) 1 Intervention (used the weekly tracker or completed a short course, n=158), or 2 Interventions (weekly tracker plus a short course, n=95). Results showed that on average, students who used the weekly tracker and completed one of the online courses experienced significant improvements in mental health symptoms and loneliness. Furthermore, using the app tracker or completing one of the online courses protected students from a reduction in academic motivation experienced in the control group. These benefits occurred even though participants’ number of academic and general stressors remained consistent across the semester. A preliminary economic analysis revealed a net benefit of $305 per participant. These findings demonstrated the helpfulness of the Sharper Minds model for improving mental health in undergraduate university students.

Abstract: Much of the research on in idual attainment in educational settings has focused on in idual differences. This chapter sets out the role of groups and group processes. After reviewing evidence for the role of social comparison in the classroom, and theory and research on ethnic group differences, we consider the impact of category memberships, stereotypes, and threat on educational performance. We introduce social identity theory and explain its relevance to educational outcomes. We then offer an integrative social identity model for education (SIME) that incorporates three elements of education research: social comparison, stereotypes, and identity. The model provides a more comprehensive perspective on the role of intergroup and intragroup relations and indicates how (and which) group memberships can present barriers to, or reveal new horizons for, performance and achievement. We describe how these elements may work together in practice and conclude by considering prospects and approaches for future research.
