Investigating social-contextual determinants of cooperation in incarcerated violent offenders.

ABSTRACT: Antisocial and psychopathic personality traits constitute a severe and treatment resistant form of externalizing psychopathology. While deficits in social information processing have been extensively investigated in these individuals, less is known about their capacity for altruism and cooperation. In particular, no studies to date have investigated whether established social-contextual determinants of cooperation, e.g., group affiliation and number of expected interactions, can motivate cooperative behaviour in antisocial individuals. The present study compared cooperative behaviour of incarcerated violent offenders (N?=?52) and controls (N?=?46) by using an established social interaction paradigm (Give Some Dilemma) where two players divide monetary units between themselves and the counterpart. Group affiliation (in- vs. out-group) and number of expected interactions (single-trial vs. repeated-trial interactions) were manipulated. Violent offenders as compared to controls shared less monetary units with their counterparts, indicating an overall reduced cooperation. Both groups showed increased cooperation rates towards in-group members and in repeated interactions. Higher psychopathic traits were associated with lower cooperation in single-trial interactions in the violent offender group. Although cooperation was comparably reduced in violent offenders, behaviour in both groups was determined by the number of expected interactions as well as group affiliation, thus providing evidence for equivalent social-contextual determinants.
