戒毒者的共情能力和情绪工作记忆的异常

Abnormality in empathy and emotional working memory among drug addicts

目的探索接受戒毒治疗的吸毒人员在共情能力和视觉工作记忆能力上是否异常,以及不同情绪材料对其工作记忆加工的影响。方法首先使用人际反应指针量表测量了戒毒者的共情能力。接下来采用延迟匹配范式测量了戒毒者和健康对照组对面孔刺激的工作记忆成绩。使用的实验材料为带有不同表情(高兴、悲伤和愤怒)的面孔图片。结果戒毒者感受他人情绪的能力和关心他人的能力之间的关系较弱。戒毒者对各情绪面孔的工作记忆正确率均高于对照组。此外,在戒毒者中,对愤怒表情的记忆正确率显著高于高兴表情;而在对照组中这一效应并不显著。结论戒毒者的共情能力在各方面较为孤立,同时对攻击性情绪如愤怒存在记忆加工上的偏向。

Objective To investigate the differences in empathy and emotional working memory between drug addicts and healthy adults. Methods Interpersonal Reactivity Index-C scale was used to assess the empathy of the drug addicts. A delayed match to sample paradigm was adopted to measure the working memory of faces. The mnemonic stimuli were face pictures with different emotions such as happy, sad or angry. Results The correlation between the abilities of emotional sensation and expression was much weaker among drug addicts than healthy adults. The accuracy of working memory was higher in the drug addicts. Drug addicts performed best in memorizing the angry faces, which was not observed in the healthy adults. Conclusion Compared to the healthy people, drug addicts showed a weaker relationship between different kinds of empathy, and a biased memory processing of threatening stimuli such as angry faces.
