Investigated the influence of trivial testimonial detail on judgments of 424 undergraduates who served as mock jurors. Ss read a summary of a court case involving robbery and murder. In Experiment 1, detailed testimony influenced judgments of guilt, even when the detail was unrelated to the culprit. In Experiment 2, detailed testimony was especially powerful when an opposing witness testified that she could not remember the trivial details. Subsequent analyses suggest that the impact of detailed testimony on guilt judgments is mediated by inferences about the eyewitnesses. When eyewitnesses provided more detail, they were generally judged to be more credible, to have a better memory for the culprit's face and for details, and to have paid more attention to the culprit.
研究了琐碎证词细节对424名担任模拟陪审员的本科生判断的影响。受试者阅读了一起涉及抢劫和谋杀案的法庭案件摘要。在实验1中，详细的证词影响了有罪判决，即使该细节与罪犯无关。在实验2中，当对立证人作证说她记不起琐碎细节时，详细的证词尤其具有影响力。随后的分析表明，详细证词对有罪判决的影响是通过对证人的推断来介导的。当证人提供更多细节时，他们通常被认为更可信，对罪犯的面孔和细节有更好的记忆，并且对罪犯给予了更多关注。
