Psychopathy is a developmental disorder associated with specific forms of emotional dysfunction and an increased risk for both frustration-based reactive aggression and goal-directed instrumental antisocial behavior. While the full behavioral manifestation of the disorder is under considerable social influence, the basis of this disorder appears to be genetic. At the neural level, individuals with psychopathy show atypical responding within the amygdala and ventromedial prefrontal cortex (vmPFC). Moreover, the roles of the amygdala in stimulus-reinforcement learning and responding to emotional expressions and (...) vmPFC in the representation of reinforcement expectancies are compromised. The implications of these functional impairments for responsibility are discussed. (shrink)

We make two suggestions with regard to Depue & Collins's (D&C's) target article. First, regarding the functioning of MOC13, we provide data indicating that, contrary to D&C's apparent position, this structure is not necessary for instrumental conditioning. Second, we suggest that D&C's approach would be advanced by reference to formal computational theory, in particular the work of Grossberg. We suggest that an integration of Grossberg's and D&C's models can provide a more complete account of extraversion.

Abstract The effect of inducing negative, positive or neutral affect on the recall of moral and conventional transgressions and positive moral and conventional acts was examined. It was found that inducing negative affect was associated with higher recall of moral transgressions while inducing positive affect was associated with higher recall of positive moral acts. Affect induction condition did not have a significant effect on the recall of the conventional transgressions or positive acts. The results are interpreted within the Violence Inhibition (...) Mechanism model of moral development (Blair, 1995) and by reference to a new, hypothesised system, the Smiling Reward Response. (shrink)
