Manifestations atypiques et configuration de la psychopathie dans la population générale

Abstract : Psychopathy is a personality configuration encompassing affective (e.g., callousness), interpersonal (e.g., egocentricity, manipulation), and behavioral (e.g., impulsivity, antisociality) characteristics. Negative outcomes associated to psychopathic personality traits have been frequently investigated. However, psychopathy has also been associated to positive outcomes and adaptive traits. This thesis aimed to better understand these manifestations. In a first part, we explored the place of positive adjustment within the psychopathy construct. The results of two studies suggest (1) the central contribution of emotional stability (i.e., unconcern, invulnerability, self-contentment) in the psychopathy network and (2) the heterogeneous distribution of adaptive traits (logical thinking, leadership, focus, extroversion) among primary and secondary variants of psychopathy. In a second part, we investigated the determinants of two atypical manifestations of psychopathy: the presence of heroic behaviors, and the low frequency of antisocial behaviors. The results of two studies showed that (1) heroic behaviors could be motivated by extrinsic social rewards or punishment, and that (2) high dispositional mindfulness was associated to decreased antisocial behaviors in individuals with high psychopathic traits. Theoretical implications of our results are discussed in a third part.
