Recidivist criminal behaviour and executive functions: a comparative study

This study sought to analyse the relation between executive functions and criminal recidivism. We assessed a set of cognitive abilities associated with executive functioning in a group of recidivist offenders (n = 19), primary offenders (n = 25) and non-offenders (n = 30). Our results, tested with nonparametric statistics and Monte Carlo method, revealed that there were no executive differences between both groups of offenders but, when compared with non-offenders, the recidivists showed a worse performance in Trail Making Test part B, and the primary offenders presented a significant lower score on Porteus Maze Test Age score. This study suggests that there can be a different pattern of executive functioning deficits associated with the offenders’ criminal record: recidivism may be more related to mental flexibility impairments and primary offenders’ antisocial behaviour may be aggravated by planning deficits.Fundação para a Ciência e a Tecnologi
