Research On The Essential Content Of Electrodermal Activity In Comprehensive Cognitive Test

Psychological-Detection Technology is a scientific technology that determines the relationship between the person to be measured and the case by detecting whether the measured person has psychological traces related to the case.After nearly a hundred years of development,it has been widely used in criminal,civil,and loyalty testing,and has played an important role.Cognitive comprehensive test is the most suitable psychological test for China's national conditions.After a lot of laboratory experiments and actual case tests prove that it has a high test accuracy.However,it is still unclear what psychological content is reflected in the most effective skin electrical indicators in the cognitive comprehensive test method.Therefore,in this study,the cognitive comprehensive test method was used as the testing method,and the simulated theft paradigm was used to explore the psychological content of the response of the skin electrical indicators in the psychological testing technology by manipulating the answering methods,thus providing laboratory data for the improvement and development of the Psychological-Detection Technology support.This study uses a simulated theft paradigm,using 180 undergraduates as subjects,and the cognition-integrated test method to distinguish the test validity of different roles of the case under the three types of answers that contain the same cognitive component and different lying components.Investigate the accuracy of the judgment of the role of the comprehensive test of the cognition group in the respondent group and the informed group and the characteristics of the map response in order to analyze the substance of the dermatological response of the cognition comprehensive test to further cognition.The scientific basis of the theoretical basis of the comprehensive test method is verified.The results of this study are as follows:1.Accuracy rates of false answers,silences,and honest answers in simulated theft cases were determined to be 78.33%(47/60),75%(45/60),and 56.7%(34/60),respectively.2.The intensity of cutaneous electroreactions and Lykken's comprehensive score on the target group were reduced in the target group under false,silent,and honest answers.3.The intensity of the electrodermal reaction in the target group of innocent informed participants decreased in the case of false answer,silence,and honest answer;the score of the subjects' Lykken score decreased in response to honesty,silence,and false answer..The results of the study show that the substance of the Cognitive Syndrome Test's skin electrical indicators reflects both the cognitive content of the person beingtested and the emotional content caused by lying to a stimulus issue.And in the cognitive comprehensive test method,there is still a high test accuracy rate under the condition of keeping silent.Lying is not a necessary condition for psychological test,but the emotional factors caused by lying make CCT more effective in distinguishing the case role from the test.
