Abstract
The present study investigated mock jurors' ( N = 541) perceptions of a hypothetical case of teacher-student sexual contact. Mock jurors read a brief vignette describing an alleged sexual encounter where the gender and age of both the teacher and student were manipulated. Participants rendered legal decisions (i.e., verdict, degree of guilt, and sentence length), as well as culpability judgments pertaining to both the teacher and the student (i.e., blame, cause, and desire for the sexual contact). In addition, the effects of mock juror gender and attitudes regarding both rape myth acceptance and homophobia were investigated. Teacher gender and both teacher and student age predicted mock jurors' recommended sentences, with male teachers, older teachers, and younger students leading to greater sentences. Overall, student age was most consistently related to multiple culpability judgments, and the culpability judgments regarding the victim were the most consistently predicted by the independent variables. We did not find any evidence of homosexist attitudes, meaning that same-gender teacher-student contact was not judged any differently than opposite-gender contact. Worth noting, we found an interaction such that male students victimized by female teachers were judged to have wanted the contact more than any other gender combination, especially by male participants. The authors discuss these findings in the context of the child sexual abuse (CSA) literature concluding that many of the findings of more prototypical CSA cases extend to the teacher-student context. We also discuss the implications of these findings in terms of gendered judgments of adolescents who are victimized by teachers, possibly decided by legal professionals, school administrators, and jurors themselves. In particular, the three-way gender interaction can be interpreted in the context of stereotypes regarding sexual development marking sexual contact between adolescent males and older females as a "rite of passage" into adulthood.

Abstract
This study used a mixed quantitative-qualitative methodology to examine whether mock jurors considered a defendant's meta-responsibility - specifically, the defendant's medication noncompliance and degree of insight into his/her schizophrenia - when determining the person's criminal responsibility. The degree of expert witness explanation regarding these factors was also varied. Participants (n = 173) were grouped into 30 juries, randomized across five conditions, and shown mock testimony and attorney arguments based on a real not guilty by reason of insanity court case. Linear mixed-modeling analysis showed that manipulations of medication compliance, insight, and expert testimony elaboration did not predict differential verdict and meta-responsibility outcomes. Nevertheless, qualitative exploration of focus groups from five juries (n = 29) indicated that participants across groups strongly considered meta-responsibility, but did so in a way that, along with a host of other considerations, suggested mock jurors were unable and/or unwilling to follow their duties as the triers of fact. Implications for legal participants, expert witnesses, and researchers are discussed.

Abstract
Classical probability theory (CPT) has represented the rational standard for decision making in human cognition. Even though CPT has provided many descriptively excellent decision models, there have also been some empirical results persistently problematic for CPT accounts. The tension between the normative prescription of CPT and human behavior is particularly acute in cases where we have higher expectations for rational decisions. One such case concerns legal decision making from legal experts, such as attorneys and prosecutors and, more so, judges. In the present research we explore one of the most influential CPT decision fallacies, the conjunction fallacy (CF), in a legal decision making task, involving assessing evidence that the same suspect had committed two separate crimes. The information for the two crimes was presented consecutively. Each participant was asked to provide individual ratings for the two crimes in some cases and conjunctive probability rating for both crimes in other cases, after all information had been presented. Overall, 360 probability ratings for guilt were collected from 120 participants, comprised of 40 judges, 40 attorneys and prosecutors, and 40 individuals without legal education. Our results provide evidence for a double conjunction fallacy (in this case, a higher probability of committing both crimes than the probability of committing either crime individually), in the group of individuals without legal education. These results are discussed in terms of their applied implications and in relation to a recent framework for understanding such results, quantum probability theory (QPT).

Abstract
To investigate dual-process persuasion theories in the context of group decision making, we studied low and high need-for-cognition (NFC) participants within a mock trial study. Participants considered plaintiff and defense expert scientific testimony that varied in argument strength. All participants heard a cross-examination of the experts focusing on peripheral information (e.g., credentials) about the expert, but half were randomly assigned to also hear central information highlighting flaws in the expert's message (e.g., quality of the research presented by the expert). Participants rendered pre- and post-group-deliberation verdicts, which were considered "scientifically accurate" if the verdicts reflected the strong (versus weak) expert message, and "scientifically inaccurate" if they reflected the weak (versus strong) expert message. For individual participants, we replicated studies testing classic persuasion theories: Factors promoting reliance on central information (i.e., central cross-examination, high NFC) improved verdict accuracy because they sensitized individual participants to the quality discrepancy between the experts' messages. Interestingly, however, at the group level, the more that scientifically accurate mock jurors discussed peripheral (versus central) information about the experts, the more likely their group was to reach the scientifically accurate verdict. When participants were arguing for the scientifically accurate verdict consistent with the strong expert message, peripheral comments increased their persuasiveness, which made the group more likely to reach the more scientifically accurate verdict.

Abstract
This study examined impressions of expert witness testimony in a not guilty by reason of insanity defense on two outcomes: witness's credibility and verdict. Borrowing in part from the "thin slice" methodology, we assessed outcomes in a 2 (deliberating vs. non-deliberating jurors) × 3 (length of videotaped testimony) between-subjects design. In 30 mock juries, 188 participants viewed the testimony by a forensic psychologist; then half of the juries deliberated. Thinner slices of the testimony were defined by the lower (30s long) and upper (5 min long) temporal bounds in the literature. The third, fuller testimony condition was 10 min long and served as the accuracy marker for the shorter sliced exposures. We aimed to explore potential consequences to jurors relying on impressions of the expert, and his or her opinion, and to test that effect post deliberation. Accounting for deliberation, brief impressions of expert credibility generally exerted a similar influence on credibility to fuller considerations. The essential finding was that a two-way interaction emerged from time slice and deliberation on verdict for jurors in the 30s condition. Overall, predictive accuracy was found in the 5 min slice, yet accuracy was not supported in the predictions based on the shortest slice. Individually-formed impressions are not likely to translate to the verdict ballot post-deliberation. Instead, brief impressions are likely to be heavily influenced by deliberation. Implications for understanding how impression-based testimony evaluations translate from the jury box to the deliberation room are discussed.

Abstract
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.

Abstract
This paper reviews the four types of validity that make up Cook and Campbell's traditional approach for social science research in general and psychological research in particular: internal validity, statistical conclusion validity, external validity, and construct validity. The most important generalizability threat to the validity of jury research is not likely a selection main effect (i.e., the effect of relying solely on undergraduate mock jurors) but is more likely the interaction of sample with construct validity factors. Researchers who try to capture the trial process with experimental paradigms may find that undergraduate mock jurors react differently to those efforts than do more representative community samples. We illustrate these issues with the seven papers that make up this volume, and conclude by endorsing Diamond's call for a two-stage research process in which findings with samples of convenience gradually add more realistic trial processes and representative samples to confirm the initial findings and increase the research program's credibility.
