Abstract:Detecting deception is an important factor in several contexts. However, people perform at chance level when detecting deception based on subjective indicators of deception and become only slightly better when trained. Therefore, objective technologies for detecting deception, such as polygraphs, have been developed. In the current study, eye tracking technology has been used in combination with subjective cues to deception regarding the eyes in order to differentiate liars from truth tellers in interrogation settings. An experiment was conducted in which participants were asked to lie about witnessing a good friend committing a crime. Based on participants’ gaze behavior, it was examined whether liars made less eye contact with the interrogator than truth tellers and whether they dissociated themselves from the lie. Also, cognitive load was manipulated with a secondary task to check whether these effects became stronger. The findings provided insufficient evidence to support the hypotheses. So, in the current study, eye tracking technology could not differentiate liars from truth tellers in interrogation settings. Nevertheless, the current study provides a basis for future research on eye tracking technology in which more can be learned about differentiating liars from truth tellers with regard to cues to deception in the eyes.
