We examined the influence of co-witness discussion on the metacognitive regulation of memory reports. Participants (N = 92) watched a crime video. Later, a confederate confidently agreed with (gave confirming feedback), disagreed with (gave disconfirming feedback), or gave no feedback (control) regarding participants' answers to questions about the video. Participants who received disconfirming feedback reported fewer fine-grain details than participants in the confirming and control conditions on a subsequent, individual recall test for a different question set. Unexpectedly, this decrease in fine-grain reporting was not accompanied by a decrease in participants' confidence in the accuracy of their fine-grain responses. These results indicate that receiving social comparative feedback about one's memory performance can affect rememberers' metamemorial control decisions, and potentially decrease the level of detail they volunteer in later memory reports. Further research is needed to assess whether these results replicate under different experimental conditions, and to explore the effects of social influences on metamemory.
我们考察了共同见证者讨论对记忆报告元认知调节的影响。参与者（N = 92）观看了一段犯罪视频。之后，一名同谋者对参与者关于视频问题的回答自信地表示赞同（给予确认性反馈）、表示反对（给予非确认性反馈）或不给予反馈（控制组）。在随后针对不同问题集的个体回忆测试中，收到非确认性反馈的参与者报告的细粒度细节比处于确认性反馈和控制组条件下的参与者更少。出乎意料的是，细粒度报告的这种减少并未伴随着参与者对其细粒度回答准确性的信心下降。这些结果表明，收到关于自己记忆表现的社会比较反馈会影响记忆者的元记忆控制决策，并可能降低他们在后续记忆报告中主动提供的细节水平。需要进一步的研究来评估这些结果在不同实验条件下是否会重现，并探索社会影响对元记忆的作用。
