Jury Panel Member Perceptions of Interpersonal‐Affective Traits of Psychopathy Predict Support for Execution in a Capital Murder Trial Simulation

Recent research with college undergraduate mock jurors suggests that how psychopathic they perceive a criminal defendant to be is a powerful predictor of whether they will support a death verdict in simulated capital murder trials. Perceived affective and interpersonal traits of psychopathy are especially predictive of support for capital punishment, with perceived remorselessness explaining a disproportionate amount of variance in these attitudes. The present study attempted to extend these findings with a more representative sample of community members called for jury duty (N = 304). Jurors reviewed a case vignette based on an actual capital murder trial, provided sentencing verdicts, and rated the defendant on several characteristics historically associated with the construct of psychopathy. Consistent with prior findings, remorselessness predicted death verdicts, as did the affective and interpersonal features of psychopathy – though the latter effect was more pronounced among jurors who were Caucasian and/or who described their political beliefs as moderate rather than conservative or liberal. Results are discussed in terms of the potentially stigmatizing effects of psychopathy evidence in capital cases. Copyright © 2013 John Wiley & Sons, Ltd.     

I am not a Crook: Effects of Denials on Perceptions of a Defendant's Guilt, Personality, and Motives

Two studies were conducted to explore the effects of a defendant's overinformative denials (i.e., denials not prompted by an accusation or specific request) in a courtroom trial. Subjects read the testimony of a defendant who either did or did not deny several negative propositions (Study I) or whose denials either were or were not in response to the prosecutor's questions (Study 2). The denials had little effect on subjects' beliefs regarding the denied propositions. However, the defendant who provided the overinformative denials was perceived as being less trustworthy, more nervous, more concerned with presenting a positive image, and more likely to believe that others believed the negative propositions. Subjects who read the testimony of this defendant also generated more negative and fewer positive thoughts, and they perceived the defendant as being more guilty. The results illustrate the importance of the conversational context for determining the pragmatic meaning of a speaker's remarks.     

Sex Differences in Self-reported Infidelity and its Correlates

We examined sex differences in the prevalence, incidence, reasons for, and consequences of infidelity. Participants (Study 1, 543 undergraduates in the Northwestern US; Study 2, 313 undergraduates and 233 community members in the Mid-Atlantic US), reported on infidelity by questionnaire. Using a broad definition of cheating, women reported being as unfaithful or more unfaithful than men. Men were more suspicious about cheating and more likely to discover the cheating than women. Women were more likely to break up with their partners, to begin new relationships after cheating, and to report reasons for cheating that may indicate a desire to switch long-term mates, such as being unhappy in the current relationship. Results are discussed in the context of evolutionary theory.     

The Impact of Race,Racial Attitude,and Gender on Reactions to the Criminal Trial of O. J. Simpson1

Opinions about the criminal trial of O. J. Simpson, as well as general racial attitude, were assessed in different samples of African Americans and Whites in three studies: during jury selection (Study 1), after closing arguments (Study 2), and after the jury verdict was reached (Study 3). We assessed the effects of respondent race, gender, and general racial attitude on case opinion factors and guilt judgments at each point in time. Race was strongly related to case opinions and guilt judgments in all three studies. Racial attitude related significantly to guilt judgments only in Study 1 for Blacks and in Study 3 for Whites. Guilt judgments of Whites were more strongly predicted by the case opinion factors than were those of African Americans. General racial attitudes and opinions about the criminal justice system were more positive for Blacks in Studies 2 and 3, while they did not differ across studies for Whites. A hindsight bias was found for Whites but not for African Americans. Race had a more powerful impact than did gender. Across-study comparison suggested that very few respondents changed their views appreciably over the year-long trial.     

When group members admit to being conformist: the role of relative intragroup status in conformity self-reports

Five studies examined the hypothesis that people will strategically portray the self as being more group influenced the more junior they feel within the group. Among social psychologists (Study 1), ratings of self-conformity by group members were greater when the status of the participant was low than when it was high. These effects were replicated in Studies 2, 3, and 4 in which relative intragroup status was manipulated. In Study 3, the authors found junior group members described themselves as more conformist than senior members when they were addressing an ingroup audience, but when they were addressing an outgroup audience the effect disappeared. Furthermore, junior members (but not senior members) rated themselves as more conformist when they were led to believe their responses were public than when responses were private (Study 5). The discussion focuses on the strategic processes underlying low-status group members' self-reports of group influence and the functional role of conformity in groups.     

Detecting children's true and false denials of wrongdoing: Effects of question type and base rate knowledge

One common and unfortunately overlooked obstacle to the detection of sexual abuse is non-disclosure by children. Non-disclosure in forensic interviews may be expressed via concealment in response to recall questions or via active denials in response to recognition (e.g., yes/no) questions. In two studies, we evaluated whether adults' ability to discern true and false denials of wrongdoing by children varied as a function of the types of interview question the children were asked. Results suggest that adults are not good at detecting deceptive denials of wrongdoing by children, even when the adults view children narrate their experiences in response to recall questions rather than provide one word answers to recognition questions. In Study 1, adults exhibited a consistent “truth bias,” leading them toward believing children, regardless of whether the children's denials were true or false. In Study 2, adults were given base-rate information about the occurrence of true and false denials (50% of each). The information eliminated the adults' truth bias but did not improve their overall detection accuracy, which still hovered near chance. Adults did, however, perceive children's denials as slightly more credible when they emerged in response to recall rather than recognition questions, especially when children were honestly denying wrongdoing. Results suggest the need for caution when evaluating adults' judgments of children's veracity when the children fail to disclose abuse.     

Adults' memories of childhood: affect, knowing, and remembering

Adult questionnaire respondents reported, for each of a number of events, if they had experienced that event during childhood and, if so, if they remembered the experience or merely knew it had happened. Respondents also rated the emotion of each event and judged whether they would remember more about each reportedly experienced event if they spent more time trying to do so. Study 1 respondents were 96 undergraduates, whereas Study 2 tested 93 community members ranging widely in age. Respondents often reported no recollections of reportedly experienced events. Reportedly experienced events rated as emotional were more often recollected than those rated as neutral, and those rated as positive were more often recollected than those rated as negative. Predicted ability to remember more was related to current memory. Claims of remembering reportedly experienced events increased with age, but predicted ability to remember more about them declined with age.     

What are we studying? Student jurors,community jurors,and construct validity

Jury researchers have long been concerned about the generalizability of results from experiments that utilize undergraduate students as mock jurors. The current experiment examined the differences between 120 students (55 males and 65 females, mean age = 20 years) and 99 community members (49 males and 50 females, mean age = 42 years) in culpability evaluations for homicide and sexual assault cases. Explicit attitude measures served as indicators of bias for sexual assault, defendant, and homicide adjudication. Results revealed that student and community participants showed different biases on these general explicit attitude measures and these differences manifested in judgments of culpability (guilt likelihood, convincingness of state's arguments, convincingness of defendant's arguments, and the defendants' criminal intentions) in sexual assault and homicide case scenarios. The results also showed that student mock jurors were more lenient when assigning guilt in homicide cases than were community members. The implications for future mock jury research are discussed.

Deception and Retribution in Repeated Ultimatum Bargaining

This paper investigates the dynamics of deception and retribution in repeated ultimatum bargaining. Anonymous dyads exchanged messages and offers in a series of four ultimatum bargaining games that had prospects for relatively large monetary outcomes. Variations in each party's knowledge of the other's resources and alternatives created opportunities for deception. Revelation of prior unknowns exposed deceptions and created opportunities for retribution in subsequent interactions. Results showed that although proposers and responders chose deceptive strategies almost equally, proposers told more outright lies. Both were more deceptive when their private information was never revealed, and proposers were most deceptive when their potential profits were largest. Revelation of proposers' lies had little effect on their subsequent behavior even though responders rejected their offers more than similar offers from truthful proposers or proposers whose prior deceit was never revealed. The discussion and conclusions address the dynamics of deception and retribution in repeated bargaining interactions.     

A comparison of students' and jury panelists' decision-making in split recovery cases

This study was designed to assess jury decision-making for 289 participants reading a medical malpractice vignette as a function of participant type (undergraduate students or jury panelists), punitive damage award apportionment (none, half, or all to the plaintiff), and compensation previously assigned to the plaintiff (low, medium, or high). We found several sample differences. Overall, jury panelists awarded more money for punitive damages. Jury panelists were also more affected by compensatory-relevant information when making punitive decisions, including assigning punitive damages and rating the fairness of the traditional apportionment scheme, where the plaintiff receives all of the money. Compared with students, more jury panelists were in favor of the plaintiff receiving the entire punitive award. Most students endorsed split recovery. The authors suggest that psycholegal research conducted solely with student samples, rather than community members, may misestimate the likely behavior of actual juries. The implications of the study for split recovery policy are also discussed.     

The group attribution error

There is a parallel between our tendency to infer the attitudes of an individual on the basis of his or her behavior, regardless of the external constraints (Jones & Harris, 1967; Ross, 1977), and our tendency to infer the attitudes of a group on the basis of the group's decision, regardless of the group decision rule. The present research focuses on this latter process. What we term the group attribution error consists of the tendency to assume that group decisions reflect members' attitudes. This assumption can be erroneous because group decision rules, in addition to members' attitudes, can influence group decisions. In Experiment 1, members of a community in which a water conservation law was or was not instituted were assumed to have correspondent attitudes, regardless of how the community decision was made. In Experiments 2 and 3, subjects inferred a greater correspondence between out-group decisions and out-group attitudes than between an in-group decision and in-group attitudes. The fourth experiment found that subjects committed the group attribution error because they attended as much to the outcome of a recall election as to the actual proportion of voters for and against the recall. Finally, Experiment 5 showed that subjects' inferences of jury members' attitudes were influenced not only by the final jury vote but also by the actual decision, which was determined by the vote plus the decision rule by which the jury was bound. The results are related to previous research on the fundamental attribution error, stereotyping, and polarized appraisals of out-groups.     

Extraversion, threat categorizations, and negative affect: a reaction time approach to avoidance motivation

The authors sought to measure a component of the avoidance self-regulation system, specifically one related to object appraisal functions. Participants performed a choice reaction time task (Studies 1 & 2) or a go/no go task (Study 3) in which they were asked to categorize words (e.g., knife) as threatening in nature. In a series of three studies involving 236 undergraduates, the authors found that introverts who were skilled at categorizing events as threatening (vs. introverts slow to do so) experienced more negative affect in their daily lives. Among extraverts, threat categorization performance did not predict negative affect. The authors suggest that implicit threat categorizations render individuals vulnerable to negative affect but that high levels of Extraversion are capable of inhibiting such affective consequences. The authors discuss implications of the findings for extant views of Extraversion, avoidance motivation, and self-regulation.

Methodological variables in Web-based research that may affect results: Sample type, monetary incentives, and personal information

There are many methodological differences between Web-based studies, differences that could substantially affect the results. The present study investigated whether sample type, offering payment through a lottery, and requiring participants to enter personal information would affect dropout rates and/or the substantive results in a study of jury decision making in capital cases. Asking participants to enter their e-mail addresses increased dropout rates, and offering payment through a lottery tended to do so as well. Participants offered payment tended to be less likely to give death sentences, and sample type moderated the influence of attitudes toward the death penalty on verdicts.     

The effect of the psychopathy checklist – revised in capital cases: Mock jurors' responses to the label of psychopathy

Despite mixed empirical evidence regarding the ability of the Psychopathy Checklist – Revised (PCL‐R) to predict violence among incarcerated inmates, it continues to be used to address such questions, even in the context of capital cases. The purpose of this study was to examine if the PCL‐R has a prejudicial effect on mock jury members during the sentencing phase of a capital murder trial. Results indicated that participants were more likely to sentence the defendant to death when the defendant exhibited a high likelihood to commit future violence, whether or not the diagnostic label “psychopath” was present. Interestingly, when asked to rate the defendant's likelihood for future violence and murder, the defendant who was a high risk for future violence and not labeled a psychopath received the highest rating. These results suggest an absence of juror bias as it pertains to the label “psychopath” when sentencing a defendant in a capital murder case. Copyright © 2010 John Wiley & Sons, Ltd.     

Individualism,authoritarianism, and attitudes toward assisted death: cross-cultural,cross-regional,and experimental evidence

We hypothesized that in individualistic cultures, individualism predicts positive attitudes toward assisted death, whereas authoritarianism is negatively associated with favorable views of this issue. Study 1 confirmed this hypothesis in a Polish sample (n=100). Study 2, using a German sample (n=102), found the predicted relationships for forms of assisted death that involved the individual self-determination of a terminally ill patient. In Study 3 (n=72), we found experimental evidence that priming individualistic aspects of the self-concept results in more favorable views of physician-assisted suicide. Using a representative sample (n=1158), Study 4 found that across the United States, regional levels of individualism are reflected in corresponding patterns of support for assisted suicide. The discussion focuses on assisted suicide as a cultural phenomenon and explores the implications of growing levels of individualism for public opinion and policy on assisted suicide.     

The negations of conjunctions,conditionals, and disjunctions

How do reasoners understand and formulate denials of compound assertions, such as conjunctions and disjunctions? A theory based on mental models postulates that individuals enumerate models of the various possibilities consistent with the assertions. It therefore predicts a novel interaction: in affirmations, conjunctions, A and B, which refer to one possibility, should be easier to understand than disjunctions, A or B, which refer to more than one possibility; in denials, conjunctions, not(A and B), which refer to more than one possibility, should be harder to understand than disjunctions, not(A or B), which do not. Conditionals are ambiguous and they should be of intermediate difficulty. Experiment 1 corroborated this trend with a task in which the participants selected which possibilities were consistent with assertions, such as: Bob denied that he wore a yellow shirt and he wore blue pants on Tuesday. Experiment 2 likewise showed that participants' own formulations of verbal denials yielded the same trend in which denials of conjunctions were harder than denials of conditionals, which in turn were harder than denials of disjunctions.     

Indigenous reconciliation in Australia: do values,identity and collective guilt matter?

This paper reports an investigation of the impact of shared values and identities on Australian attitudes towards Indigenous reconciliation across two studies. In Study 1, University students were assigned to one of two conditions in which they completed a questionnaire that measured their value priorities and reconciliation attitudes; either as an individual or as an Australian. As expected, the value of egalitarianism was the strongest predictor of reconciliation attitudes, especially under the Australian condition. In Study 2, participants from the general community were assigned into conditions that manipulated identity (personal vs. Australian) and views of how Indigenous Australians have been treated by Europeans in the past (favourable vs. unfavourable). Under these conditions, participants were asked to report their level of collective guilt and reconciliation views. The results showed that collective guilt was stronger under the unfavourable than the favourable history condition but only when personal identity was salient. The findings also showed some support for the proposition that reconciliation views would be most positive under the unfavourable history condition when Australian identity was salient. The implications of the findings for advancing the progress of indigenous reconciliation in Australia are discussed. Copyright © 2006 John Wiley & Sons, Ltd.     

Involvement in Ethnic Organizations and Community Activism Among Asian Immigrants in the United States

This study examines whether ethnic organization members have a lower likelihood of community activism than multiethnic organization members as predicted by social capital approaches to collective civic engagement. Community activism is measured by whether the respondent has worked with others in his or her community to solve a problem in the last 12 months. Data come from the 2008 National Asian American Survey, and the sample is limited to five major Asian immigrant groups (the Chinese, Asian Indians, Filipinos, Koreans, and the Vietnamese) for group-specific analyses. Findings suggest that membership in ethnic organizations does not necessarily diminish the probability of community activism: For the Chinese and Asian Indians, members of ethnic organizations have a higher probability of community activism than their non-joiner counterparts. Yet, consistent with the prediction of social capital approaches, there is a significant difference in the probability of community activism between members of multiethnic organizations and non-joiners for all ethnic groups, except for the Vietnamese. Nevertheless, findings show that there is no significant difference in the likelihood of community activism between members of ethnic organizations and those of multiethnic organizations for each ethnic group. Thus, data from the 2008 NAAS fail to provide compelling evidence to support the social capital argument that involvement in ethnic organizations has a significantly weaker effect on collective civic engagement than involvement in multiethnic organizations. This paper concludes with a discussion of the implications of these findings.
