Antisociality, underarousal and the validity of the Concealed Information Polygraph Test.
The Concealed Information Polygraph Test has been advocated as the preferred method for the physiological detection of deception. In this study, we further examined the validity of the Concealed Information Test in antisocial individuals. Physiological responding to concealed information was assessed in 48 male prisoners, and compared with responding in 31 male community volunteers. Based upon the association between antisociality and autonomic hyporesponsivity, lower detection rates were expected in the prisoners. Participants were questioned on five personally significant items (e.g., day of birth), instructed to deny recognition of this information, and promised a financial reward when able to hide recognition. Prisoners showed reduced autonomic reactivity in comparison to the community volunteers. This hyporesponsivity had little impact on the sensitivity of the Concealed Information Test. Detection efficiency in the prisoners was significantly above chance (d=2.67; a=0.82; 79%), and did not differ significantly from that obtained in the community volunteers (d=3.04; a=0.85; 87%). The present data support the validity of the Concealed Information Test in criminal populations.
