摘要
目的 探讨抑郁症患者对负性情绪词的情绪与记忆偏好。方法 对 27名抑郁症患者及与之匹配的 29名正常对照组进行抑郁自评量表评定。测验完成后用E Prime系统分别进行正、负性情绪词识别的实验,包括 3个子实验,分别为正性情绪词、负性情绪词以及正 负性情绪词的识别。结果 与正常对照组相比,抑郁症患者在正、负性情绪词的反应时存在显著性差异,较正常对照组长 40ms左右;就患者自身而言,不论是单任务还是双任务,其在负性情绪词上的反应时要短于在正性情绪词上的反应时 40ms左右,且差异有显著性。患者正确再认出的正、负性情绪词的个数与正常对照无明显差异,但患者正确再认出负性情绪词的个数明显多于正性情绪词的个数且存在显著性差异。结论 抑郁症患者在负性情绪词上的反应时较正性情绪词短,再认出较多的负性情绪词,即对负性情绪词存在负性偏好。
ObjectiveTo explore the emotional and memory preference to the negative emotional words. Methods27 major depression patients and 29 normal controls were assessed by Self-Rating Depression Scale (SDS) on admission. After self-rating, all were required to react to the positive and negative emotional words by E-Prime system. The experiments included three sub-one: to identify the positive emotional words, the negative emotional words and the positive-negative emotional words. ResultsThe reaction times of both the positive and the negative emotional words of the patients were, about 40ms,longer than those of the normal controls. But to the patients themselves, no matter in single or double task, the reaction time of the negative emotional words was, about 40ms,shorter than that of the positive emotional words. No significant difference was found in the recognition of the positive and negative emotional words between the patients and the normal controls. The patients did memory, about 1.8,more in the negative emotional words than in the positive emotional words. ConclusionThe reaction time of the negative emotional words was shorter than that of the positive emotional words in major depression and the patients recognized more in the negative emotional words. The patients showed some preference to the negative emotional words.
