Comparison Of The Accuracy Of Control Question Test,Systemic Polygraph Examination For Investigation,Cognitive Comprehensive Test

The technology of criminal psychological test is a technique to identify the relationship between the suspect and the case,and has become one of the important means to solve the difficult cases.However,there are still different testing methods at home and abroad,which are based on Control Question Test(CQT),Systemic Polygraph Examination for Investigation(SPEI),Cognitive Comprehensive Test(CCT).In practice,there are great differences between the three testing methods.At present,there is a lack of research on the accuracy of three different methods.Therefore,this study used experimental paradigm for the simulation of bribery theft,simulation of three kinds of test method of overall test accuracy are compared,and then respectively for the detection of the three test methods of crime subjects,the subjects and innocent subjects to test the accuracy of comparison,in order to test the accuracy of the above three kinds of test verification method,provide laboratory support for real case application of psychological testing technology.Two experiments were used to simulate theft paradigm,bribery simulation paradigm,with college students as subjects,to draw in the form of random case role(burglar / bribery,insider,innocent),after the end of the simulation,the subjects were tested using CQT,SPEI,CCT method,three kinds of test methods to test the accuracy of comparison,to investigate the effects of different testing methods in different situations in the crime of test accuracy whether there are differences.The experimental results show that CQT,SPEI,CCT test accuracy of the existence of significant differences,the CQT and SPEI test accuracy rate does not exist significant differences,namely the CCT than CQT and SPEI with high accuracy,and can effectively distinguish in the case of role.The same case roles respectively using CQT,SPEI,CCT to test the accuracy,research results show that the simulation for theft and bribery cases,the CQT,SPEI,CCT role of the test accuracy rate does not exist significant differences;SPEI and CCT are no significant difference in the insider role in testing;SPEI and CCT testing accuracy does not exist significant differences,but to know the role of insider CCT test accuracy rate is higher than the SPEI;for the role of innocent subjects,CQT has a high false positive,SPEI and CCT test accuracy rate was higher than that of CQT,SPEI and CCT accuracy does not exist significantdifferences.The results of this study provide data support for the laboratory test of different testing methods,and have certain value for the scientific application of the psycho-physiological test technology.
