Abstract: Objective To examine the effects of different answering modes on the galvanic skin response (GSR) in the concealed information test (CIT). Methods A total of 150 participants were recruited and randomly assigned to different experimental conditions according to the experimental design. The GSR of each participant was scored using the Lykken scoring method. The accuracies of the GSR for both perpetrators and innocent participants were analyzed under the three answering modes in the CIT: silence, honest answer, and deceptive answer. Results The accuracies of identifying perpetrators under the answering modes of silence, honest answer, and deceptive answer were 53.3%, 33.3%, and 86.7%, respectively. The accuracies of identifying innocent participants under the answering modes of silence and honest answer were 100% and 93.3%, respectively. Conclusion Answering modes have a certain influence on the GSR in the CIT, which can provide a reference for the standardized application and criteria development of polygraph testing technology.

摘要： 目的 考察不同回答方式对隐藏信息测试法（concealed information test，CIT）中皮肤电反应（galvanic skin response，GSR）指标的影响。方法 招募150名参与者，根据实验设计随机抽签分配到不同的实验条件，采用莱克肯（Lykken）评分法对每位参与者的GSR进行评分，分析CIT中沉默、诚实回答、谎答三种回答方式条件下，作案参与者和无辜参与者的GSR指标判定准确率。结果 作案参与者在沉默、诚实回答、谎答回答方式条件下的认定准确率分别为53.3%、33.3%和86.7%；无辜参与者在沉默和诚实回答方式条件下的认定准确率分别为100%、93.3%。结论 回答方式对CIT中GSR指标有一定的影响，可为多道心理测试技术的规范应用和标准制定提供参考。
