Abstract

Deception, especially unexpressed deception, concealment, is difficult to detect from words and behavior. Thus, psychophysiological approaches are used to detect deception. One such approach is the Concealed Information Test (CIT). The CIT is used in criminal investigations to examine a subject’s concealing of a memory through autonomic and/or central nervous activities. In contrast, psychophysiologists generally infer cognitive processes from physiological responses. This study aimed to reveal the cognitive processes of concealing the memory by reviewing physiological responses during the CIT. We demonstrated that the intent to conceal memory (or withdrawal motivation) would increase the significance of the memory and recruit controlled processes, such as monitoring and inhibition of physiological responses.
