An experiment to assess emotional and physiological arousal and personality correlates while imagining deceit

In order to examine how personality traits, emotional arousal and physiological arousal affect deception confidence, students (N = 102) completed the Eysenck Personality Questionnaire-Revised (EPQ-R) as well as stress and deception tasks while their heart rate variability was measured. Findings indicated psychoticism did not moderate how physiologically aroused participants were while viewing emotionally salient stimuli (video of a road traffic accident) or the thought of enacting deceit, although this came close to significance. However, participants (particularly males) higher in psychoticism reported less subjective distress after imagining enacting deceit than those lower on psychoticism. Extroversion had no impact on physiological arousal when viewing emotionally salient stimuli or thinking about enacting deceit. However, extroverts reported more subjective distress after thinking about enacting deceit than introverts. Also, deception confidence was not correlated to any of these variables. Future research could examine a sample higher in psychoticism and how this trait impacts deception confidence.
