Reports of emotions experienced over the past week can be influenced by memory bias, which is more pronounced for people with depression. No studies, however, have examined memory bias for specific emotion clusters (e.g., sadness, anxiety, and anger) experienced on a day-to-day basis among people with depression or a history of depression. Participants (N = 1,657) from the Midlife in the United States Study were assessed for depression. Approximately 6 months later, participants reported their emotional experiences for 8 days and recalled these experiences on the final day. Differences in recalled and reported emotion were compared between participants with and without a history of depression. Participants overestimated experience only of negative emotions, particularly anger, and this negativity bias was greatest for participants with a history of depression. Feelings related to anger were prone to greater overestimation than sadness or anxiety. These findings emphasize the role of memory bias in retrospective reports of specific emotions and illustrate the presence of an amplified memory bias among people who are at a greater risk for recurrent depressive episodes.
关于过去一周内所经历情绪的报告可能会受到记忆偏差的影响,而这种影响在抑郁症患者中更为明显。然而,目前尚无研究检查过抑郁症患者或有抑郁症病史的人群日常经历的特定情绪簇(如悲伤、焦虑和愤怒)的记忆偏差。来自美国中年生活研究的参与者(N=1657)接受了抑郁评估。大约 6 个月后,参与者报告了他们 8 天的情绪体验,并在最后一天回忆了这些体验。比较了有和没有抑郁症病史的参与者之间回忆和报告的情绪差异。参与者仅对负面情绪(尤其是愤怒)的体验存在过高估计,而这种负面偏差在有抑郁症病史的参与者中最大。与愤怒相关的情绪比悲伤或焦虑更容易被高估。这些发现强调了记忆偏差在特定情绪的回顾性报告中的作用,并说明了在更容易出现复发性抑郁发作的人群中存在放大的记忆偏差。
