Collaborative inhibition refers to the phenomenon that when several people work together to produce a single memory report, they typically produce fewer items than when the unique items in the individual reports of the same number of participants are combined (i.e., nominal recall). Yet, apart from this negative effect, collaboration may be beneficial in that group members remove errors from a collaborative report. Collaborative inhibition studies on memory for emotional stimuli are scarce. Therefore, the present study examined both collaborative inhibition and collaborative error reduction in the recall of the details of emotional material in a laboratory setting. Female undergraduates (n = 111) viewed a film clip of a fatal accident and subsequently engaged in either collaborative (n = 57) or individual recall (n = 54) in groups of three. The results show that, across several detail categories, collaborating groups recalled fewer details than nominal groups. However, overall, nominal recall produced more errors than collaborative recall. The present results extend earlier findings on both collaborative inhibition and error reduction to the recall of affectively laden material. These findings may have implications for the applied fields of forensic and clinical psychology.
协同抑制是指这样一种现象，即当几个人共同生成一个单一的记忆报告时，他们通常比将相同数量的参与者的个体报告中的独特项目进行组合（即名义回忆）时产生的项目要少。然而，除了这种负面影响之外，协作可能是有益的，因为小组成员可以从协作报告中消除错误。关于情绪刺激记忆的协同抑制研究很少。因此，本研究在实验室环境中检查了情绪材料细节回忆中的协同抑制和协同错误减少。女性大学生（n = 111）观看了一段致命事故的电影片段，随后以三人一组的形式进行了协作（n = 57）或个体回忆（n = 54）。结果表明，在几个详细类别中，协作组回忆的细节比名义组少。然而，总的来说，名义回忆产生的错误比协作回忆多。本研究结果将协同抑制和错误减少的早期发现扩展到了对情感材料的回忆。这些发现可能对法医和临床心理学的应用领域具有重要意义。
