| Outline of Final Research Achievements |
The concealed information test (CIT) is used for criminal investigations and examines an examinee’s recognition on crime-relevant information from physiological responses. Although the CIT is a recognition detection test, the CIT is performed only when the examinee may be concealing the crime-relevant information. The present study manipulated the intention to conceal during the CIT and decomposed physiological responses into recognition- and concealment-related responses. The recognition of crime-relevant information elicited orienting responses, because the information is significant for the examinee. In contrast, the intention to conceal elicited controlled process to monitor and inhibit the orienting responses. On the basis of these findings, I proposed a cognitive process model for the CIT.
