There is a body of research to suggest that psychopathic individuals have both structural and functional deficits in the prefrontal cortex, affecting the interplay between proactive and reactive executive control mechanisms as a determinant for behaviour. Individual differences within psychopathy sub-groups have been shown to vary in this executive function ability. This study aims to further refine previous studies, looking specifically at the duel mechanisms of control in a sub-clinical sample, in order to apply the knowledge gained to the clinical/criminal population for further enhancement of behaviour management. A convenience mixed sample of 130 participants each took part in two high congruent (4:1) standard Stroop paradigm tasks, each containing 100 trials. One task was fixed congruent and the other was randomly dispersed. Mean Stroop interference was calculated for each participant in both conditions. Participants were categorised into low/high boldness, meanness and disinhibition, using the Triarchic Psychopathy Measure (Patrick, Fowles & Krueger, 2009). Results showed an effect of psychopathy trait dimension on Stroop interference effect, but not on task condition.
