【摘要】 目的:探讨回溯性评估对恐惧消退返回的影响。方法:采用心理生理实验法,引入双耳分听实验技术范式,记录30名大学生被试对非条件性刺激(US)的预期值和对条件性刺激(CS)的皮肤电反应。结果:通过言语指导语告知被试"由于耳机故障,所以刚才左侧耳机听不到声音,右侧耳机一直运行正常"后,被试对CSl的皮肤电反应和对US预期值显著高于CSr与CSn,出现了显著的恐惧消退返回。结论:回溯性评估能够影响条件性恐惧的消退返回,进一步证明命题模型的合理性,为临床中更好实施暴露疗法提供了实验支持。更多还原

【Abstract】 Objective:The study was designed to investigate the effect of retrospective revaluation on the return of fear after extinction.Methods:Participants were 14 male and 16 female college students.The experimental design was a 4(phase:baseline,acquisition,extinction,test)×3(CS:CSl,CSr,CSn) within subjects.Two novel animal phones were presented as CS+s,one followed an unpleasant sound from the left headphone,labeled CSl,the other followed an unpleasant sound from the right headphone,labeled CSr.All the participants went through the same baseline,acquisition,extinction phases.Results:The skin conductance response and the unexpected stimuli(US) expectancy of CSl increased significantly compared to that of CSr and CSn.Conclusion:Retrospective inferences concerning the absence of the US during extinction may give rise to a return of fear.更多还原
