The present study examined the role of political orientation and task engagement in juror decision-making. The study was conducted as a 2 (mode: laboratory versus online) × 2 (role: juror, observer) × 3 (evidence: admissible, inadmissible, control) between-subjects experiment, with participants ( = 157) recruited from a mid-sized Australian university. Findings supported our predictions that political conservatism is associated with convictions, and that university students endorse a wide range of political orientations. Participants who were more engaged in the study perceived more threat in the defendant, and threat, in turn, led to higher conviction rates; furthermore, the effect of participation mode on verdict decisions was completely mediated by perceptions of the threat posed by the defendant. Findings are discussed in terms of their implications for jury decision-making research and its relevance to actual juror decisions.
本研究考察了政治倾向和任务参与度在陪审员决策中的作用。该研究采用了一项两因素被试间实验设计，其中一个因素是2水平的“模式”（实验室与在线），另一个因素是2水平的“角色”（陪审员、观察者），还有一个因素是3水平的“证据”（可采纳、不可采纳、对照），参与者（n = 157）从一所澳大利亚中型大学招募。研究结果支持了我们的预测，即政治保守主义与定罪相关，且大学生认可广泛的政治倾向。更投入研究的参与者在被告身上察觉到更多威胁，而这种威胁反过来导致更高的定罪率；此外，参与模式对裁决决定的影响完全由对被告所构成威胁的认知所介导。研究结果将根据其对陪审团决策研究的意义及其与实际陪审员决策的相关性进行讨论。
