In two experiments, we investigated how social comparative feedback affects the metacognitive regulation of eyewitness memory reports. In Experiment 1, 87 participants received negative, positive, or no feedback about a co-witness's performance on a task querying recall of a crime video. Participants then completed the task individually. There were no significant differences between negative and positive feedback groups on any measure. However, participants in both of these conditions volunteered more fine-grain details than participants in the control condition. In Experiment 2, 90 participants answered questions about a crime video. Participants in the experimental groups received either positive or negative feedback, which compared their performance to that of others. Participants then completed a subsequent recall task, for which they were told their performance would not be scored. Feedback did not significantly affect participants' confidence, accuracy, or the level of detail they reported in comparison to a no feedback control group. These findings advance our understanding of the boundary conditions for social feedback effects on meta-memory.
在两项实验中,我们研究了社会比较反馈如何影响目击者记忆报告的元认知调节。在实验1中,87名参与者收到了关于共同目击者在询问犯罪视频回忆任务中的表现的负面、正面或无反馈。然后参与者单独完成任务。负面和正面反馈组在任何指标上均无显著差异。然而,这两种情况下的参与者比对照组的参与者自愿提供了更多细粒度的细节。在实验2中,90名参与者回答了关于犯罪视频的问题。实验组的参与者收到了正面或负面反馈,将他们的表现与其他人的表现进行了比较。然后参与者完成了后续的回忆任务,被告知他们的表现不会被评分。与无反馈对照组相比,反馈并未显著影响参与者的信心、准确性或他们报告的细节程度。这些发现推进了我们对社会反馈对元记忆影响的边界条件的理解。
