虚假记忆误导信息干扰范式故事场景图片的编制及评定

The Establishment and Assessment of Scene Pictures Based on Misinformation Paradigm of False Memory

目的:以图片形式编制不同情绪效价的生活事件故事场景作为标准化的事件虚假记忆实验材料。方法:通过78名在校大学生对初选的常见生活事件场景进行愉悦度评定,选取9个不同情绪效价的场景进行剧情脚本编制和图片拍摄;再请119名在校大学生对编制的故事场景图片进行愉悦度、唤醒度、熟悉度和趋向度的9点量表评定。结果:构建的生活事件场景在愉悦度上区分为正性(7-9分)、中性(4-6分)、负性(1-3分)三类;编制的三类生活事件故事场景图片在愉悦度上差异显著(F=1223.393,P<0.05),在趋向度上差异显著(F=360.068,P<0.05);三类故事场景图片在唤醒度和熟悉度上无显著差异;三类故事场景图片的愉悦度和趋向度呈正相关(r=0.37~0.62,P<0.01)。结论:本研究编制的生活事件场景图片能有效区分不同情绪效价,是事件虚假记忆研究的标准化实验材料。

Objective:To establish a set of scene pictures of life events with different emotional valence,and offer standard experimental materials for event-based false memory studies.Methods:Firstly,78 university students rated the emotional valence of preliminarily selected life event scenarios;Secondly,9 scenarios with different emotional valence were selected for scripting and photo shooting;Thirdly,119 university students were recruited to assess each scenario on following emotional dimensions:valence,arousal,familiarity and appulsion.All assessment were performed on a 9-point rating scale.Results:The established scenarios could be distinguished as positive(7-9 points),neutral(4-6 points) and negative(1-3points) events based on emotional valence,and could be operated for scripting and picture shooting.There were significant differences between established positive,neutral and negative scene pictures on the dimension of valence and appulsion(F=1223.393,P<0.05;F=360.068,P<0.05,respectively).The differences between established positive,neutral and negative scene pictures on the dimension of arousal and familiarity were not significant(P>0.05).The valence and appulsion of established positive,neutral and negative scene pictures were highly correlated(r=0.37~0.62,P<0.01).Conclusion:The present study has established a reliable set of scene pictures which can effectively distinguish positive,neutral and negative scenarios based on emotional valence.Therefore,the established life event scene pictures could be used as standard experimental materials in event-based false memory studies.
