【摘要】 目的:探讨抑郁症患者是否存在注意偏倚,并分析其注意偏倚的时程特征。方法:采用点探测任务,要求受试尽快对探测点的位置进行判断。采用重复测量方差分析,比较抑郁症患者和对照组在不同条件(不同的情绪图片配对、不同的图片呈现时间)下,对探测点作出反应的平均反应时差异。结果:抑郁症患者的平均反应时显著长于对照组;当图片呈现时间为500ms时,抑郁组对负性图片的脱离指数显著大于控制组的脱离指数。结论:抑郁症患者在500ms时对负性图片存在注意脱离困难,而在100ms时则不存在这种注意偏倚特征。更多还原

【Abstract】 Objective:To investigate whether clinically depressed patients show attentional bias and the time characteristics of their attentional bias.Methods:A probe detection task,was used to compare the response latencies showed by clinically depressed patients and control group under the probes replacing the picture stimulus in different conditions.Results:The average response latencies showed by clinically depressed patients were longer than those showed by control participants.When the picture-pairs were displayed for 500ms,the depressed group had higher disengaging scores for the negative stimulus compared with the control group.Conclusion:The clinically depressed patients have difficulties in disengaging attention from negative information at 500ms but not at 100ms.更多还原
