Abstract

In this study, we consider concurrently a disorder view and functional design view of psychopathy using different methods of fluctuating asymmetry (FA) and a target and rater paradigm involving filmed interactions. Targets were young men (N = 46) assessed on psychopathic traits and FA who took part in a video recorded deceptive emotion story where they were incentivized to convince others and gain their trust. Raters were young men and women (N = 1060) who rated the target's videos for genuineness and trust, followed by measures of individual differences such as personality traits. Results showed psychopathy was not related to FA. However, psychopathy was related to higher trust ratings over and above target men's attractiveness and appearance. Additionally, men highest in psychopathy scored significantly higher genuineness and trust ratings compared to men lowest in psychopathy. Lastly, interactions between rater's sex and personality predicted preferential ratings for high psychopathy men, with women higher in Emotionality showing more genuineness and trust of high psychopathy men. Findings suggest that in deceptive emotion contexts young men higher in psychopathy may be successful at convincing others and gaining trust, and particularly so from those with certain personality traits, which may indicate selective exploitation.
