抑郁大学生在情绪stroop任务中的认知加工偏向

Cognitive Processes Bias of Emotional Stroop Task in Depressive College Students

目的探讨抑郁大学生是否存在消极社交依赖自我图式,以丰富抑郁的认知理论。方法采用流调中心用抑郁量表(CESD)、焦虑自评量表(SAS)对某大学500名学生进行测量,筛选出符合要求的被试共77名,其中抑郁组24人,焦虑组12人,抑郁焦虑组17人,正常对照组24人。严格筛选社交依赖人格形容词作为实验刺激,对抑郁组、焦虑组、抑郁焦虑组、正常对照组施测情绪stroop任务。结果抑郁组对消极词汇的颜色命名时间显著长于对积极词汇的颜色命名时间(P<0.01),抑郁组对状态类词汇的颜色命名反应时间正偏向显著低于正常对照组(P<0.05),而对特质词的反应时间正偏向差异无统计学意义(P>0.05)。结论抑郁大学生具有的消极社交依赖自我图式是状态性的,尚未发展到特质成分。

Objective To test whether depressive college students have a negative sociotropic self-schemata. Methods A total of 500 college students were surveyed by CES-D and SAS, and 77 college students were chosen for further experiment： 24 with depressive mood, 12 with anxious mood, 17 with depressive and anxious mood, 24 normal ones. Sociotropic adjectives were strictly developed, and 4 groups （depressive vs. anxious vs. depressive and anxious vs. normal） were given emotional stroop task. Results Color naming reaction time of depressed group for negative words were significantly longer than positive words（P0.01）. For state adjectives, color naming reaction time bias of depressed group was significantly lower than control group （P0.05）. Conclusion Depressive college students have a negative sociotropic schemata with state content.
