| Psychological testing technology is based on the principle that people's psychological activity will cause changes in physiological indicators,by presenting to the measured person a problem that is designed in advance,and then triggering the psychophysiological response of the measured person,and simultaneously collecting and recording the measured physiological and physiological tester.Changes in the physiological indicators caused by human psychological activities,thereby judging and inferring the relationship between the measured person and the case(s)being investigated.It has been used for more than 100 years since it was used to assist in the investigation of cases.Through the unremitting efforts of researchers,it has developed a variety of testing methods and has been widely used to assist case investigation,insurance claims investigation,national security and important positions.In areas such as personnel screening and loyalty reliability testing,Japan and other countries have incorporated it into the judicial evidence system.Over the years,researchers and users have put forward a variety of theoretical hypotheses to describe psychological testing techniques,mainly including fear theory,stress theory,motivation theory,conflict theory,conditional reflex theory,and cognitive awakening theory.The current research paradigms of psychological testing technology mainly include Comparison Question Test(CQT),Concealed Information Test(CIT)and Differentiation of Deception(DOD).The theory,validity,and actual cases of these three paradigms and their variants are discussed.The combination of use research to promote the development of psychological testing technology.Cognitive Comprehensive Test(CCT)is an improvement of the CIT,It is a psychophysiological detection technique that uses the self(involved person)cognitive test questions,criminal knowledge test questions,and real-time psychological test questions as test elements for comprehensive detection to detect subject's cognitive situation of the case and relationship with the case.CCT has been proven through a large number of actual case tests and laboratory studies that can effectively identify the role of the case.However,regardless of CCT or other test methods,subjects in the experiment were less involved than those in the real case.Under the laboratoryconditions,the degree of involvement of the subjects was not enough.The impact of different evasion detection motives on the validity of multi-channel psychophysiological tests has been affected.Although previous researchers have done relevant research,the impact of escaping test motivation under CCT conditions on test validity has not been studied.In this study,180 college students were selected as subjects,and 2(low evasion detection motives,high evasion detection motives)*3(perpetrators,ignorant and innocent persons)were used in the design of the test room,and 8 sets of test subjects were prepared for assessment.The relationship between the evasive detection motivation and the test validity of CCT was investigated by using the dermatological electrical response and comprehensive scores of different subjects with different evasion motivation levels and the accuracy of the test results.The results of the study show that: CCT can effectively distinguish between innocent group participants,innocent group participants,and crime group participants under different levels of escaping motivation.Under the condition of low evasive motivation,CCT tests three kinds of roles.The accuracy rates are 100%,83.3%,and70%,respectively.Under the condition of high evasion motivation,the accuracy of CCT for three types of roles are 100%,93.3%,and 93.3%,respectively.The CCT is more effective in distinguishing innocent people and perpetrators under conditions of high evasion motivation. |
