Two studies were conducted with separate student and community samples to explore the effect of sample types and the influence of defendant mental illness on juror decision-making. Following the completion of a pre-trial questionnaire in which jurors' attitudes towards mental illness were assessed, participants were provided with a robbery trial transcript, wherein the mental illness of the defendant was manipulated. Participants then answered a questionnaire to assess their knowledge of the scenario, their verdict, verdict confidence, and sentencing decision. Limited relationships were found between the variables in both Study 1 and Study 2. Neither attitude ratings nor mental illness type had a significant effect on juror decisions. Samples differed in terms of the paths through which juror decisions were achieved. Findings suggest that sample type may be particularly relevant for this topic of study, and that future research is required on legal proceedings for cases involving a defendant with a mental illness.
进行了两项研究，分别以学生和社区样本为对象，以探讨样本类型的影响以及被告精神疾病对陪审员决策的影响。在完成一份预审问卷（其中评估了陪审员对精神疾病的态度）后，向参与者提供了一份抢劫案审判记录，其中对被告的精神疾病情况进行了人为设置。参与者随后回答了一份问卷，以评估他们对该场景的了解、他们的裁决、裁决信心以及量刑决定。在研究1和研究2中，各变量之间均发现了有限的关系。态度评分和精神疾病类型对陪审员的决策均无显著影响。样本在陪审员达成决策的途径方面存在差异。研究结果表明，样本类型可能与该研究主题特别相关，并且需要对涉及患有精神疾病的被告的案件的法律程序进行进一步研究。
