自我损耗对情绪自传体记忆具体性的影响

Reduced Specificity of Emotional Autobiographical Memories Following Self-regulation Depletion

目的:探讨健康个体受到自我损耗后情绪自传体记忆具体性的变化。方法:将60名健康个体随机分配到损耗组和控制组中,首先采用Stroop颜色辨别范式令损耗组被试自我损耗,控制组实施匹配的无关任务,然后采用自传体记忆测验(AMT)测量两组被试情绪自传体记忆具体性的变化。结果:相对于控制组来说,损耗组在AMT中表现出自传体记忆具体性降低的特点;在排除了心境水平的影响后,积极词和消极词所提取的自传体记忆具体性之间有明显差异。结论:健康个体受到自我损耗后会使自传体记忆的具体性降低,且线索词诱发的情绪对自传体记忆的具体性也有一定的影响。

Objective： Combining with the Color Stroop task and autobiographical memory test（AMT） to explore the ef- fects of self-regulation resources depletion on emotion autobiographical memory specificity. Methods： 60 participants were recruited and divided into depleted group（n=30） and controlled group（n=30）. The present study used a Color Stroop task, in- volving naming the ink colors of incongruous color words, to deplete self-regulation resources prior to retrieving a series of autobiographical memories to emotional cue words--the Autobiographical Memory Test（AMT）, whereas controlled group read color words written in black ink prior to the AMT. Results： Compared with the control group, the depleted group showed decreased specificity of autobiographical memory. Further, after controlling the effect of mood state, significant dif- ferences specificity of autobiographical memory performances between positive-word and negative-word cuing task. Con- clusion： This suggests that ego depletion can reduce specificity of autobiographical memory, and that emotion triggering al- so influences the specificity of autobiographical memory.
