In the study of emotional memory bias in depressed individuals, most previous studies have used emotional materials, but there were significant differences in the effects of different emotion-inducing methods on face memory. In the present study, two experiments were conducted to explore the effects of different emotion-inducing methods on memory between healthy participants and non-clinically depressed participants. The results from experiment 1 showed that when feedback was used as induction, the memory performance of the non-clinical depression group was significantly higher than that of the healthy group under the condition of negative feedback. Under positive and neutral feedback, there were no significant differences between the two groups. In experiment 2, when emotional materials were used as a mode of induction, no significantly difference in each emotional condition between the healthy and depressed groups was found. The results of the present study show that different methods of emotional induction have different effects on depressed participants. Compared with the emotion induced by the emotional material, the non-clinical depressed participants had a better memory effect induced by negative emotional events.
在抑郁个体的情绪记忆偏差研究中,大多数先前的研究都使用了情绪材料,但不同的情绪诱发方法对面孔记忆的影响存在显著差异。本研究通过两个实验,探讨了不同的情绪诱发方法对健康被试和非临床抑郁被试记忆的影响。实验 1 的结果表明,当反馈被用作诱发手段时,在负反馈条件下,非临床抑郁组的记忆表现明显高于健康组。在正反馈和中性反馈条件下,两组之间没有显著差异。在实验 2 中,当情绪材料被用作诱发模式时,健康组和抑郁组在每种情绪条件下均无显著差异。本研究结果表明,不同的情绪诱发方法对抑郁个体有不同的影响。与情绪材料诱发的情绪相比,非临床抑郁个体对负性情绪事件的记忆效果更好。
