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。
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 bv 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. ③Suhject＇s EDA is influenced by characteristics of his reaction.
