The emergence of psychopathy: implications for the neuropsychological approach to developmental disorders

In this paper, I am going to examine the disorder of psychopathy and consider how genetic anomalies could give rise to the relatively specific neuro-cognitive impairments seen in individuals with this disorder. I will argue that genetic anomalies in psychopathy reduce the salience of punishment information (perhaps as a function of noradrenergic disturbance). I will argue that the ability of the amygdala to form the stimulus-punishment associations necessary for successful socialization is disrupted and that because of this, individuals with psychopathy do not learn to avoid actions that will harm others. It is noted that this model follows the neuropsychological approach to the study of developmental disorders, an approach that has been recently criticized. I will argue that these criticisms are less applicable to psychopathy. Indeed, animal work on the development of the neural systems necessary for emotion, does not support a constructivist approach with respect to affect. Importantly, such work indicates that while environmental effects can alter the responsiveness of the basic neural architecture mediating emotion, environmental effects do not construct this architecture. However, caveats to the neuropsychological approach with reference to this disorder are noted.     

Establishing and maintaining treatment effects with less intrusive consequences via a pairing procedure

The generality and long-term maintenance of a pairing procedure designed to improve the efficacy of less intrusive procedures were evaluated for the treatment of problem behavior maintained by automatic reinforcement exhibited by 2 individuals with developmental disabilities. Results suggested that a less intrusive procedure could be established as a conditioned punisher by pairing it with an effective punisher contingent on problem behavior. Generalization across multiple therapists was demonstrated for both participants. However, generalization to another setting was not achieved for 1 participant until pairing was conducted in the second setting. Long-term maintenance was observed with 1 participant in the absence of further pairing trials. Maintenance via intermittent pairing trials was successful for the other participant.     

Effects of Violent Video Games on Aggressive Behavior: Potential Sex Differences

Evidence of the effects of playing violent video games on subsequent aggression has been mixed. This study examined how playing a violent video game affected levels of aggression displayed in a laboratory. A total of 43 undergraduate students (22 men and 21 women) were randomly assigned to play either a violent (Mortal Kombat) or nonviolent (PGA Tournament Golf) video game for 10 min. Then they competed with a confederate in a reaction time task that allowed for provocation and retaliation. Punishment levels set by participants for their opponents served as the measure of aggression. The results confirmed our hypothesis that playing the violent game would result in more aggression than would playing the nonviolent game. In addition, a Game × Sex interaction showed that this effect was larger for men than for women. Findings are discussed in light of potential differences in aggressive style between men and women.     

Peace and Justice: A Limited Reconciliation

This paper aims to relax the tension between the political requirements of making peace and the moral demands of doing justice, in light of the ‘peace processes’ in South Africa and Northern Ireland. It begins by arguing that criminal justice should be reconceived as consisting primarily in the vindication of victims, both direct and indirect. This is not to deny the retributive punishment of perpetrators any role at all, only to insist that it be largely subservient to the goal of vindication. Why should we take such an account of justice to be true? The paper offers two reasons. First, Christians – and even secularist liberals – have a prima facie reason in the consonance of this account with the Bible's eudaimonistic conception of justice as ordered to the restoration of healthy community. Second, since all concepts of criminal justice share the basic notion of putting right what is wrong, it would be odd if the repair of damage done to victims (i.e., their ‘vindication’) were not prominent among its concerns; and there are reasons to suppose that this vindication should actually predominate in relation to the other principles of justice (the retributive ‘balancing’ of crime and punishment, and the reform of the criminal for his own sake). In its final sections, the paper applies the proposed conception of criminal justice to the ‘peace processes’ in South Africa and Northern Ireland, and concludes that in both cases, notwithstanding concessions to the politics of peace-making, considerable justice has been done.     

On the status of knowledge for using punishment implications for treating behavior disorders

In this paper, we review basic and applied findings on punishment and discuss the importance of conducting further research in this area. The characteristics of responding during punishment and numerous factors that interact with basic processes are delineated in conjunction with implications for the treatment of behavior disorders in clinical populations. We conclude that further understanding of punishment processes is needed to develop a highly systematic, effective technology of behavior change, including strategies for improving the efficacy of less intrusive procedures and for successfully fading treatment.     

Understanding the Dark Side of Costly Punishment: The Impact of Individual Differences in Everyday Sadism and Existential Threat

In public goods situations, a specific destructive behaviour reliably emerges when individuals face the possibility of costly punishing others: antisocial punishment, that is, costly punishing cooperative individuals. So far, however, little is known about the individual differences and situational factors that are associated with the dark side of costly punishment. This research deals with this shortcoming. We argue that antisocial punishment reflects the basic characteristics of sadism, namely, aggressive behaviour to dominate and to harm other individuals. We further argue that antisocial punishment may reflect a type of behaviour that allows for the maintenance of self‐esteem (through aggressively dominating others). Therefore, we expect that individuals who report a disposition for everyday sadism are particularly likely to engage in antisocial punishment when their self has been threatened (by thinking about one's own death). In a study (N = 99), we found empirical support for this assumption. The present research contributes to a better understanding of antisocial punishment and suggests that sadistic tendencies play a crucial role, especially when the self is (existentially) threatened.
