Evaluating the Feasibility of Using Noncontact Sensors to Conduct a Targetless Concealed Information Test

The standard Concealed Information Test (CIT) requires the use of target items to elicit physiological response differences between those concealing information and those naïve to target items. Interpersonal Deception Theory contends that deceivers often exhibit both strategic and nonstrategic behaviors in an attempt to appear truthful. This paper proposes a study designed to ascertain the feasibility of using noncontact sensors to conduct a target less CIT to elicit cues of strategic and nonstrategic behaviors indicative of concealed knowledge and deception. The ability to implement a CIT without target items increases the feasibility of CIT use in a number of border control, passenger screening, and document adjudication contexts.
