The neuropsychology of offending

Abstract

Structural damage or abnormality of the brain may be related to offending. What is known about the consequences of lesions to the frontal and temporal lobes and of the results of head injury, suggests psychological changes that might well enhance the risk of offending, and in particular violent offending. Evidence from two sources is reviewed, that based on studies of offender groups and that based on those follow-up studies of clinically defined samples of head injury victims which have reported offence related outcomes. Despite some methodological limitations, the balance of evidence is that frontal damage and possibly temporal lobe damage is related to offending, particularly violent offending, and that head injury can act to precipitate offence related behaviour. It is suggested that future research needs to concentrate more on the factors that mediate the link between brain damage and offending behaviour.     

The self-selection of democracies into treaty design: insights from international environmental agreements

Generally, democratic regime type is positively associated with participating in international environmental agreements. In this context, this study focuses on the legal nature of an agreement, which is linked to audience costs primarily at the domestic level that occur in case of non-compliance and are felt especially by democracies. Eventually, more legalized (“hard-law”) treaties make compliance potentially more challenging and as democratic leaders may anticipate the corresponding audience costs, the likelihood that democracies select themselves into such treaties decreases. The empirical implication of our theory is that environmental agreements with a larger share of democratic members are less likely to be characterized by hard law. Results from quantitative analyses strongly support our argument, shed new light on the relationship between participation in international agreements and the form of government, and also have implications for the “words-deeds” debate in international environmental policy-making.     

Aggression control therapy for violent forensic psychiatric patients: method and clinical practice

Aggression control therapy is based on Goldstein, Gibbs, and Glick's aggression replacement training and was developed for violent forensic psychiatric in- and outpatients (adolescents and adults) with a (oppositional-defiant) conduct disorder or an antisocial personality disorder. First, the conditions for promoting "treatment integrity" are examined. Then, target groups, framework, and procedure are described in detail, followed by the most important clinical findings during the period 2002 to 2006. Finally, new programme developments are mentioned, with aggression control therapy as a starting point.     

Understanding human aggression: New insights from neuroscience

The present paper reviews and summarizes the basic findings concerning the nature of the neurobiological and behavioral characteristics of aggression and rage. For heuristic purposes, the types of aggression will be reduced to two categories — defensive rage (affective defense) and predatory attack. This approach helps explain both the behavioral properties of aggression as well as the underlying neural substrates and mechanisms of aggression both in animals and humans. Defensive rage behavior is activated by a threatening stimulus that is real or perceived and is associated with marked sympathetic output. This yields impulsivity with minimal cortical involvement. Predatory attack behavior in both animals and humans is generally planned, taking minutes, hours, days, weeks, months, or even years (with respect to humans) for it to occur and is directed upon a specific individual target; it reflects few outward sympathetic signs and is believed to require cortical involvement for its expression. Predatory attack requires activation of the lateral hypothalamus, while defensive rage requires activation of the medial hypothalamus and midbrain periaqueductal gray (PAG). Both forms of aggressive behavior are controlled by components of the limbic system, a region of the forebrain that is influenced by sensory inputs from the cerebral cortex and monoaminergic inputs from the brainstem reticular formation. Control of aggressive tendencies is partly modifiable through conditioning and related learning principles generated through the cerebral cortex.     

The violent reconvictions of sexual offenders

The violent reconvictions of a sample of sexual offenders discharged from prison between 1992 and 1996 (who had not been reconvicted of a sexual offence) were examined. The hypothesis was that a proportion of these violent reconvictions would have a sexual motivation. The sample consisted of 104 adult male sexual offenders for whom detailed information regarding their violent reconviction was available. The sample was categorized according to the motivation of the violent reconviction. It was found that a proportion of the violent reconvictions were sexually motivated (12%) and that some of these had resulted from an original charge for a sexual offence. Significant differences were found between the sexual motivation and violent motivation group on the number of criminal history and victim characteristic variables. It was concluded that, in the case of sexual offenders, violent convictions might mask the true motivation of the offence.     

The statistical prediction of violent behavior

Considerable attention in the popular and professional literature has focused on the relative costs and benefits of using public protectionist versus civil libertarian models of social control. In this article, we develop statistical analogs of these models to predict violent behavior among samples of defendants found incompetent to stand trial in New York State. The societal and personal costs (errors of prediction) of each model are compared and their implications for clinical practice and social policy are discussed.This research was supported in part by PHS Grant MH 20367 from the NIMH Center for Studies of Crime and Delinquency.

Interpersonal violent crime in Ghana: The case of assault in Accra

This study examined the trends, patterns, and socio-spatial conditions and factors that foster assaultive incidents and behaviors in Accra, Ghana. Specifically, the study examined how much assaults occurred over time, background characteristics of the victims and offenders, victim-offender relationships, and the housing units that recorded the most assaults. Among the triggers of assaults were females in familial settings and neighborhood propinquity, that is, disputants related through kinship, residential proximity, and contractual obligations. Arguments, drunkenness name-calling, jokes, funerals, inheritance, property, festivals, chieftaincy, communal living and sharing, such spatial factors as transient populations and routine activities were among the remote and immediate causes of the assaultive incidents. Among the housing units, the compound houses recorded the highest assaults. The majority of the victims and suspects were young males, between eighteen and thirty-four years, unemployed or in low paying blue-collar jobs. The majority of the assaults occurred in Accra Central, the precinct with the most compound homes and lower-class neighborhoods, followed by Nima, Kaneshie, and Kpeshie. Most assault incidents occurred in the morning, between 6:00 a.m. to 9:00 a.m. and in the afternoon, between 5:00 p.m. to 7:00 p.m.     

The impact of pre-treatment responsivity and treatment participation on violent recidivism in a violent offender sample

This study assessed whether pre-treatment responsivity (psychopathy, motivation to attend treatment, denial and minimisation of offending behaviour, and feelings of guilt or shame) predicted violent recidivism and/or moderated the effectiveness of a violence intervention programme. Participants were 114 male violent offenders who were referred to a structured violent offender group treatment programme; 84 offenders commenced the programme. Results showed that treatment completion did not have a significant main effect on recidivism but that psychopathy scores moderated the effects of treatment. Offenders with high scores on the Psychopathy Checklist: Screening Version (PCL:SV) who were rated as having good engagement with treatment, or who completed treatment, had similar violent recidivism rates compared to offenders with low PCL:SV scores. In contrast, offenders with high PCL:SV scores who dropped out of treatment or were poorly engaged had significantly higher rates of violent recidivism. These findings indicate that treatment effectiveness could be enhanced, and greater reductions in recidivism achieved, if programmes find ways to engage and maintain psychopathic offenders in treatment.     

The effect of gender on violent and nonviolent recidivism: A meta-analysis

A large body of literature has been dedicated to understanding re-offending after release from prison - a phenomenon known as recidivism. A meta-analysis was conducted using fifty- seven published studies on actuarial predictors of both violent and nonviolent recidivism in men and women. The current analysis resulted in 127 effect sizes between violent recidivists and non-recidivists, and sixty-eight effect sizes between violent recidivists with nonviolent recidivists. Several variables (drug/alcohol use, age, and marriage) were predictive of recidivism. Gender differences were also observed. In men, increased violent criminal history was associated with increased violent recidivism. This effect was not true for women. In fact, longer sentences were predictive of violent re-offending in women and not men. Despite limited data on women, pursuing the predictors of recidivism in men and women independently demonstrated that gender differences exist, and supported the need for more data concerning the predictors of recidivism in women.     

The efficacy of foot patrol in violent places

Objectives

This study examines the effectiveness of foot patrol in violent micro-places. A large urban police department deployed foot patrol in micro-places (hot spots) for a period of 90 days for two shifts each day. Our objective is to determine whether this activity impacted violent crime in these hot spots and whether spatial displacement of crime occurred.

Methods

Eight eligible foot beat locations were set by examining crime rates for previous years in order to identify micro-places of high criminal activity. We employed a quasi-experimental design comparing the four treatment to the four control areas, estimating panel-specific autoregressive models for 30 weeks prior to and 40 weeks after the treatment.

Results

Time series models revealed statistically significant reductions in violent crime in the micro-places receiving foot patrol treatment, while no such reductions were observed in the control areas. The deterrent effect, however, was short and dissipated quickly. Control areas did not experience any crime prevention benefit during this time period. No evidence of crime displacement to spatially contiguous areas was detected.

Conclusions

This contributes to the growing body of knowledge that focused police strategies within hot spots impact violent crime. Specifically, the implementation of foot patrol in high crime hot spots led to measurable reductions in aggravated assaults and robberies, without displacing crime to contiguous areas.

     

The diagnosis of intermittent explosive disorder in violent men

In a study of violent men, 443 symptomatic adult male volunteers were evaluated for presence of intermittent explosive disorder (IED). Investigators first established presence of severe and frequent violent outbursts not readily explainable by another disorder. Seventy-nine violent men were so selected. Of these, 26 had excessive impulsivity, an exclusionary criterion for IED. Twenty-one were excluded because of other, exclusionary mental disorders. Violent behavior of five subjects was deemed proportionate to the provocation. Insufficient data were obtained for an accurate diagnoses of IED in 12 subjects. Fifteen subjects satisfied all criteria for IED, i.e., 18.9 percent of sufficiently violent men without other major psychopathology or 1.49 percent of all 443 men who complained of violence. Epidemiologic and validity aspects of IED are discussed.     

Criminal profiles of violent juvenile sex and violent juvenile non sex offenders: an explorative longitudinal study

Few studies have longitudinally investigated the criminal profiles of violent juvenile sex and violent juvenile non-sex offenders. To make up for this lack, this study used police records of juveniles to determine the nature of the criminal profiles of violent sex offenders (n = 226) and violent non-sex offenders (n = 4,130). All offenders committed their first offense in 1996 and were followed for 7 years. Results showed that violent sex offenders and violent non-sex offenders cannot be considered a homogeneous group because of different background characteristics and criminal profiles. Sex and violent offenses often constitute a small part of a broader criminal pattern. Further research is necessary to reveal in more detail the developmental and criminological patterns of violent and sexual delinquency. Treatment and intervention programs may benefit from this.     

The social context of violent victimization: A study of the delinquent peer effect

Haynie's (2001) work on the structural dimensions of peer networks demonstrated how the characteristics of networks may influence individual delinquent behavior. This study extends the network approach to the prediction of violent victimization. The National Longitudinal Survey of Adolescent Health (Add Health) is used to examine how the friendship-network characteristics of centrality, density, and popularity affect vulnerability. The findings indicate that central and popular members of dense conventional groups experienced lower levels of violent victimization, while the opposite was true of similarly situated members of delinquent networks. Implications for victimization and research related to the specification of how delinquent peer associations promote vulnerability are discussed.

The effectiveness of electronic monitoring with violent male parolees

Research on electronic monitoring (EM) has ignored its effectiveness with high-risk, violent offenders. This article examines the effectiveness of using EM as a supervision tool for violent male parolees by comparing those who were mandated to such supervision who were released in fiscal year 1996 (N = 128) to a random sample who did not receive such supervision who were released in fiscal year 1995 (N = 158). Effectiveness was assessed by examining return to prison and time to failure within four years of release. The results indicated that, after controlling for relevant demographic and criminal history variables, EM had no direct effect on the likelihood of recommitment to prison or time until failure. Parolees who reported drug problems and those with lower parole-success likelihood scores were more likely to fail and to fail more quickly. Sex offenders on EM were less likely to return to prison than those not on EM, and those on EM who eventually returned to prison remained in the community longer than did those not on EM. Implications for the usefulness of EM as a tool in parole supervision are discussed.     

The prediction of violent behavior during short-term civil commitment

The predictive validity of the clinical judgment of dangerousness in the context of short-term civil commitment was studied prospectively by comparing the behavioral scale ratings of both verbal and physical aggression between 37 persons committed on the basis of "danger to others" versus 31 persons committed on other grounds. No statistically significant difference was found between these two groups of detainees with regard to the levels of aggression measured during their approximately three-day detention. This finding is in agreement with abundant previous research which documents the inability of psychiatrists to accurately predict future dangerousness, prompting the author to suggest that the "dangerousness" criterion for civil commitment be rejected. Although society is unlikely to resurrect the broadly defined "in need of treatment" criterion because of its historically demonstrated ever present potential for abuse, the author suggests an alternative criterion for civil commitment which, in perhaps a more well-defined and more practical way, would allow the state to maintain its doctrine of parens patriae toward mental patients.     

The prevalence and nature of violent offending by females

The purpose of the current study was to examine the nature and prevalence of violent offending by females. Using National Incident-Based Reporting System (NIBRS) data from 1998, this study examined the relationship between cooffending and type of offense as well as the type of weapon(s) used during violent incidents and the race of the perpetrators. The findings suggest that females are more likely to be involved in aggravated assaults compared with robberies and murder or nonnegligent manslaughter. This is particularly true for females who commit their violent crimes alone. When females cooffend with other females or males, however, they are more likely to commit robberies. Overall females are more likely to be involved in violent incidents where either personal weapons or knives are used. When females cooffend with males, however, more likely to be involved in incidents with guns. Finally, the current study found that Black females were more likely to commit violent offenses with other females, whereas White females were more likely to commit violent offenses with males.     

The role of violence in street crime: a qualitative study of violent offenders

Studies on the motivation for violent street crime, such as robbery and assault, have tended to draw on either the rational choice or the subcultural perspective. This study explores the extent to which violence on the street can be explained by rational factors associated with the successful commission of the offence or social factors related to street culture. The study is based on qualitative interviews with 55 violent street offenders who were serving sentences for street robbery and assault in six prisons in the United Kingdom. The findings, based on accounts of 101 incidents of street violence, identified four main explanations for street violence: (a) successful offence enactment, (b) buzz and excitement, (c) status and honor, and (d) informal justice. The article concludes that there might be benefits in combining the insights of both perspectives by generating an integrated theory that would properly explain both the rational and the seemingly irrational components of street violence.     

Schizophrenia and violent crime: the experience of parents

Individuals with schizophrenia have an increased risk of committing a violent crime, although their contribution to the overall criminality in society is small. In this qualitative study we have interviewed parents of adult sons, diagnosed with schizophrenia and who recently had been referred to forensic psychiatric treatment due to a violent crime, with an aim to explore the parents' experiences and emotional reactions. Four events, or status passages, emerged as crucial and common for all parents. These were the onset of the mental disorder, the diagnosis of schizophrenia, the violent behaviour/criminality and the recent referral to forensic psychiatric treatment. Every passage evoked strong emotional reactions such as guilt, fear, disappointment, anger and relief, which in return led to different actions taken. Unawareness of the character and severity of their sons' mental illness and the type of violent criminality they had committed were common and complicated contacts both between the parents and their sons, and also between family members and official authorities. The findings emphasize that psychiatric health care professionals must take the initiative and responsibility for information, education and support of family members.     

The reduction of violent crime through economic equality for women

Normally we do not link the reduction of violent crime with equal rights for women, this paper traces such a linkage. Central to the logic of this argument is that the distribution of the frequency of violent crime is often described by a bimodal curve which supposedly distinguishes between minor, unimportant offenders and a distinct group of serious offenders: the target for many policies being the latter. In fact, this bimodal distribution does not exist; therefore, policies based on it will be fruitless. The larger group of minor offenders is basically ignored. The distribution of violence is better described as a continuous skewed curve which retains its shape. Thus, an effective policy to reduce violence would have to shift the entire curve to the left. Reducing the more numerous acts of lesser violence rather than concentrating on the rarer cases of extreme violence would be more effective. Since much violence is nurtured in family settings, policies that decrease stress in family settings would have a meaningful impact on future violence. Stress could be reduced with greater economic equality for women, making it possible for them to leave potentially violent domestic settings. In the long term this would have an impact on violent crime.
