Do introverts and extraverts use different deception cues in detecting deception?

Forty six undergraduates from Algoma University College were tested with the Eysenck Personality Questionnaire. The subjects viewed a video recording of deceptive or truthful videos containing questions pertaining to occupation, health, personal accomplishments, hobbies and lifestyle. During a pause after each video a questionnaire was given. The participants were requested to rate the truthfulness of the interviewee, and asked to rate the nine cues to their decision. In this study deception cues such as speech error, video interview content, self manipulation, hand gestures, eye contact, tone of voice, speech disturbances, posural shifts and smile duration were related to either introverted or extraverted personality characteristics. The results indicate that there were no differences between extraverts and introverts in either estimates of trutfulness or cue importance.
