People who perform a cognitively demanding secondary task while recalling a distressing memory often experience the memory as less emotional, vivid, or accurate during subsequent recollections. In this experiment, we tested whether the emotional valence (positive versus neutral) and sensory modality (visual, auditory, or both) of a secondary task diminishes the emotionality, vividness, and accuracy of memory of distressing videos.
Participants (N = 156) viewed a distressing video and were then randomized to one of six groups in a 2 (Emotional Valence: positive, neutral) × 3 (Modality: visual, auditory, combined) design. Participants were then exposed to an amusing or a neutral clip that was visual, auditory, or audiovisual. They were asked to recall the distressing video during exposure to the clip. Participants rated the emotionality and vividness of their memory of the distressing video, and completed recognition tests regarding its visual and auditory details before and after exposure to the secondary clip.
Participants who recalled the distressing video while exposed to the amusing clip rated their memory of the distressing video as less distressing (but not less vivid or accurate) than did participants exposed to the neutral clip. Modality had no significant effects Limitations. Participants were not trauma survivors, and the memories targeted were stressful, but subtraumatic.
Inducing positive emotion during recollection of distressing memories may diminish the emotional distress prompted by subsequent recollection.
在回忆一段痛苦记忆时执行一项认知要求较高的次要任务的人,在随后的回忆中往往会觉得这段记忆的情感色彩没那么强烈、没那么生动或没那么准确。在本实验中,我们测试了次要任务的情感效价(积极与中性)和感觉模态(视觉、听觉或两者皆有)是否会降低对痛苦视频记忆的情感性、生动性和准确性。
参与者(N = 156)观看一段痛苦视频,然后被随机分配到2(情感效价:积极、中性)×3(模态:视觉、听觉、组合)设计的六个组中的一组。参与者随后观看一段有趣的或中性的视觉、听觉或视听剪辑。要求他们在观看剪辑时回忆痛苦视频。参与者对他们对痛苦视频记忆的情感性和生动性进行评分,并在观看次要剪辑前后完成关于其视觉和听觉细节的识别测试。
在观看有趣剪辑时回忆痛苦视频的参与者,比起观看中性剪辑的参与者,认为他们对痛苦视频的记忆没那么痛苦(但生动性和准确性没有降低)。模态没有显著影响。局限性。参与者不是创伤幸存者,且所针对的记忆是有压力的,但低于创伤水平。
在回忆痛苦记忆时诱发积极情绪可能会减轻后续回忆引发的情绪困扰。
