【摘要】 目的:探讨个体认知状态与皮肤电反应之间的关系,为改进测谎技术提供科学依据。方法:以42名大学生作为被试,运用照片再认法,以不同认知任务为素材进行测谎测试。结果:不同认知任务下,被试皮肤电反应差异显著,其中识记过的照片引起更强烈的皮肤电反应。结论:①皮肤电反应确实存在着认知效应。②皮肤电反应还受到说谎引起的“非认知”因素的控制与影响。③皮肤电反应还可能会受到被试反应性质的影响。更多还原

【Abstract】 Objective: To examine the relationship between cognition states and electrodermal activity(EDA) and to provide evidence for improvement of lie-detection technique. Methods: 42 university students participated in the study. They were provided with tasks that elicited different levels of cognition by means of photo recognition in polygraph test. Results: Significant difference in EDA was observed in different cognitive tasks. Conclusion: ①There is cognitive effect of EDA in lie detection. ②EDA is also influenced by non-cognitive factors that are brought by lie reaction. ③Subject’s EDA is influenced by characteristics of his reaction.更多还原
