Exposure to another's account of a shared event can influence the content of an individual's memory report. We examine whether the emotionality of the to-be-remembered information influences the likelihood that socially encountered post-event information is accepted into memory. Participants were exposed to positive, negative or neutral emotional pictures. Subsequently, they had to discriminate these pictures from new pictures in a 'yes/no' recognition decision either before or subsequent to a confederate providing misinformation, accurate or no information. Post-event information influenced participants' responding in the recognition test. Effects were larger for participants viewing neutral items and persisted for these items on a subsequent private source monitoring test. These findings indicate that people rely more on information from others when encountering non-emotional compared to emotional items. We suggest that increased memory strength in conjunction with access to strong retrieval cues in the recognition test serves to shield emotional items from vulnerability to effects of memory conformity.
接触他人对共同事件的描述会影响个体记忆报告的内容。我们研究了待记忆信息的情感性是否会影响在社交中遇到的事件后信息被纳入记忆的可能性。参与者观看了积极、消极或中性情感的图片。随后，在一名同谋提供错误信息、准确信息或不提供信息之前或之后，他们必须在“是/否”识别判断中区分这些图片与新图片。事件后信息影响了参与者在识别测试中的反应。对于观看中性项目的参与者，影响更大，并且在随后的私人来源监测测试中这些项目的影响持续存在。这些发现表明，与情感项目相比，人们在遇到非情感项目时更多地依赖他人的信息。我们认为，识别测试中增强的记忆强度以及获得强烈的检索线索有助于保护情感项目免受记忆一致性效应的影响。
