Behavioral and physiological measures in the detection of concealed information.
The authors examined the incremental validity of the reaction time (RT) measure beyond that of skin conductance response (SCR) in the detection of concealed information. Participants performed a Stroop-like task in which they named the color of critical and neutral words. Results show that the SCR highly differentiated between the relevant and neutral words. However, the RT demonstrated a signi...
متن کاملFace and Voice as Social Stimuli Enhance Differential Physiological Responding in a Concealed Information Test
Attentional, intentional, and motivational factors are known to influence the physiological responses in a Concealed Information Test (CIT). Although concealing information is essentially a social action closely related to motivation, CIT studies typically rely on testing participants in an environment lacking of social stimuli: subjects interact with a computer while sitting alone in an experi...
متن کاملDetecting Criminal Intent with the Concealed Information Test
Lie detection procedures are typically aimed at determining whether a suspect is lying about a crime committed in the past. Recent threats of terrorism, however, have shifted attention away from solving old cases to preventing future crimes. In the experiment reported in this paper, we investigate whether a specific lie detection test, the Concealed Information Test, can be used to detect crimi...
متن کاملSeparating deceptive and orienting components in a Concealed Information Test.
The Concealed Information Test (CIT) requires the examinee to deceptively deny recognition of known stimuli and to truthfully deny recognition of unknown stimuli. Because deception and orienting are typically coupled, it is unclear how exactly these sub-processes affect the physiological responses measured in the CIT. The present study aimed at separating the effects of deception from those of ...
متن کاملAutomatic blush detection in "Concealed information" test using visual stimuli
Blushing has been identified as an indicator of deception, shame, anxiety and embarrassment. Although normally associated with the skin coloration of the face, a blush response also affects skin surface temperature. In this paper, an approach to detect a blush response automatically is presented using the Argus P7225 thermal camera from e2v. The algorithm was tested on a sample population of 51...
