Pornography use and sexual aggression: the impact of frequency and type of pornography use on recidivism among sexual offenders

In this study, we examined the unique contribution of pornography consumption to the longitudinal prediction of criminal recidivism in a sample of 341 child molesters. We specifically tested the hypothesis, based on predictions informed by the confluence model of sexual aggression that pornography will be a risk factor for recidivism only for those individuals classified as relatively high risk for re-offending. Pornography use (frequency and type) was assessed through self-report and recidivism was measured using data from a national database from the Royal Canadian Mounted Police. Indices of recidivism, which were assessed up to 15 years after release, included an overall criminal recidivism index, as well as subcategories focusing on violent (including sexual) recidivism and sexual recidivism alone. Results for both frequency and type of pornography use were generally consistent with our predictions. Most importantly, after controlling for general and specific risk factors for sexual aggression, pornography added significantly to the prediction of recidivism. Statistical interactions indicated that frequency of pornography use was primarily a risk factor for higher-risk offenders, when compared with lower-risk offenders, and that content of pornography (i.e., pornography containing deviant content) was a risk factor for all groups. The importance of conceptualizing particular risk factors (e.g., pornography), within the context of other individual characteristics is discussed.

The importance of individual differences in pornography use: theoretical perspectives and implications for treating sexual offenders.

This article reviews the extant literature regarding pornographys influence on antisocial attitudes, sexual arousal, and sexually aggressive behavior in both noncriminal and criminal samples. The article concludes that when examined in the context of multiple, interacting factors, the findings are highly consistent across experimental and nonexperimental studies and across differing populations in showing that pornography use can be a risk factor for sexually aggressive outcomes, principally for men who are high on other risk factors and who use pornography frequently. Finally, this article presents theoretical implications based on these findings, as well as some clinical implications relevant to the assessment and treatment of sexual offenders.

Pornography, Sex Crime, and Paraphilia

The current paper reviews research findings concerning the association of pornography with sexual violence and paraphilic interests. Little clarity concerning the causal impact of pornography on sexual aggression or child-oriented sexual behavior has been achieved in the scientific literature. Laboratory experimentation demonstrates that violent pornography may contribute to antiwoman aggression, but the artificiality and constraints of the experimental setting severely limit generalization of these findings to real-world situations, and observational studies in natural settings consistently find no association or an inverse association of pornography with sexual aggression. In addition, although pedophiles often use child pornography, the causal impact of child pornography on child sexual offending is not conclusive. The current analysis considers the confluence of predisposing factors and pornography use as issues requiring clinical judgment in the reduction of sexual aggression and management of paraphilic interest in children.

Can sexual offenders be treated

There are many misconceptions about sexual offender treatment. This is not only a problem in the lay press and media but is also a problem amongst mental health professionals. In part, this relates to the inadequate teaching about sexual deviation in medical schools and psychiatric residency programs and even in forensic psychiatric fellowships. Other disciplines, such as psychology, have educated mental health professionals in a more balanced way related to the assessment and treatment of sexual offenders but still the understanding, knowledge and acceptance that sexual offender treatment is available, is evidence-based, and is successful as shown in treatment outcome studies is still misunderstood. This review covers the evidence-based studies that support the efficacy of sexual offender treatment.

A Pilot Study of Electrocortical Activity in Dysfunctional Anger: Decreased Frontocortical Activation, Impaired Attention Control, and Diminished Behavioral Inhibition

Dysfunctional anger, though not a primary clinical diagnosis per se, does present clinically as a pathological mood for which treatment is sought. Few studies have probed the neurocortical correlates of dysfunctional anger or assessed if cognitive processes, such as attention, are altered in dysfunctional anger. Though dysfunctional and high trait anger appears to be associated with biased processing of anger-eliciting information, few studies have examined if dysfunctional anger modulates attention more generally. This is a notable gap as volitional attention control is associated with effective emotive regulation, which is impaired in dysfunctional anger and in associated acts of aggression. In this pilot study, we examined performance and electroencephalographic (EEG) profiles during a 12-min continuous performance task (CPT) of sustained attention in 15 adults with dysfunctional anger (Anger group) and 14 controls (control group). The Anger group had fewer hits at the end of the CPT, which correlated with decreased frontocortical activation, suggesting decreased engagement of frontal circuits when attention is taxed. The Anger group had more false alarms overall indicating impaired response inhibition. Increased right cortical activation during the initial portion of CPT existed in the Anger group, perhaps reflecting greater engagement of frontal circuits (i.e. effort) during initial stages of the task compared to controls. Finally, increased overall beta₁ power, suggesting increased cortical activation, was noted in the Anger group. These EEG patterns suggest a hypervigilant state in dysfunctional anger, which may interfere with effective attention control and decrease inhibition. Such impairments likely extend beyond the laboratory setting, and may associate with aggressive acts in real life.

Pedophilic brain potential responses to adult erotic stimuli

Cognitive mechanisms associated with the relative lack of sexual interest in adults by pedophiles are poorly understood and may benefit from investigations examining how the brain processes adult erotic stimuli. The current study used event-related brain potentials (ERP) to investigate the time course of the explicit processing of erotic, emotional, and neutral pictures in 22 pedophilic patients and 22 healthy controls. Consistent with previous studies, early latency anterior ERP components were highly selective for erotic pictures. Although the ERPs elicited by emotional stimuli were similar in patients and controls, an early frontal positive (P2) component starting as early as 185 ms was significantly attenuated and slow to onset in pedophilia, and correlated with a clinical measure of cognitive distortions. Failure of rapid attentional capture by erotic stimuli suggests a relative reduction in early processing in pedophilic patients which may be associated with relatively diminished sexual interest in adults.

The Limits of Ecological Psychology

Gillett and Huang (2013) argue for two claims: first, that an ecological perspective on psychopathy adds to our understanding of the disorder, and, second, that this perspective supports a moral claim regarding the obligations of society to pychopaths. We are in general agreement with the authors. The biomedical model of mental disorders that currently dominates psychiatry, especially in North America, has undoubtedly obscured the contribution of environmental factors in the development of psychopathology, and an ecological perspective could make an important theoretical contribution. In addition, an obligation of concern for the marginalized, including those with psychopathy, is morally uncontroversial. Our disagreement lies in specifics: We believe that the relevance of the ecological approach to psychopathy has not been adequately defended, and that an ecological approach does not support the moral claim defended by the authors, even if the moral claim is true. We consider both of these issues in turn. Gillett and Huang’s claim about the importance of the environment to the development of psychopathy does not distinguish between psychopathy, which is not a Diagnostic and Statistical Manual of Mental Disroders (DSM) diagnostic category, and antisocial personality disorder (ASPD), which is. Psychopathy is a construct that includes emotional unresponsiveness and antisocial behavior as central features. People with psychopathy are often diagnosed with ASPD, but only one-third of those who are diagnosed with ASPD meet the criteria necessary for psychopathy (Hart and Hare 1996). ASPD thus represents a psychologically heterogeneous population, and the relative contribution of genes and environment to that condition is likely to differ depending on a variety of factors. In contrast to ASPD, the extent to which the environment contributes to psychopathy is more controversial. Currently there are no known environmental factors that explain the pathophysiology of psychopathy (Blair 2007), although there is a link between a history of child abuse and some features of the disorder (Poythress et al. 2006). Furthermore, even though some psychopathic traits have been correlated with environmental factors, current research has found that environmental stressors,
