Crime location choices: A geographical analysis of German serial killers

The present study examined whether there are different processes operating in the crime location choices between body‐disposing and non‐body‐disposing serial killers and between sexual serial killers and acquisitive serial killers. A sample of 49 series of solved German serial killings is used to examine the differences in travelled distances between these groups of killers. Nonparametric tests revealed that body‐disposing and non‐body‐disposing serial killers and sexual and acquisitive serial killers did not constitute subgroups of serial killers regarding their spatial behaviour. The results suggest that the compared groups are subjected to the same factors that influence their travelled distances. Furthermore, the possible role of planning and anticipated emotions in crime location choices of serial killers is discussed, as well as the limitations of the study and recommendations for future research.     

Serial killers: I. Subtypes,patterns, and motives

Part I of this two-part article outlines the history of serial killing and describes the varying patterns and motives for this type of crime. It reviews the assorted typologies of serial killers that have been elaborated by different researchers and offers an integrative classification of primary serial killer subtypes. In addition to the commonly cited male, heterosexual, solitary sadistic sexual homicide offender, this article describes a number of subpopulations of serial killers, including sadist–masochist, female, couple, homosexual, and professional serial killers. Part II will examine the developmental factors, neuropsychodynamics, and forensic applications of serial killing.     

Will They Do It Again? Predicting Sex-Offense Recidivism

This article reviews the empirical research on the prediction of reoffending among sexual offenders. The major predictors of sexual-offense recidivism are factors related to sexual deviance (e.g., deviant sexual preferences, previous sex crimes) and, to a lesser extent, criminal lifestyle (e.g., antisocial personality disorder, total number of prior offenses). The factors that predict general recidivism among sex offenders are the same as the factors that predict general recidivism among nonsexual criminals (e.g., juvenile delinquency, prior violent offenses). Given that there are special predictors of sexual recidivism, evaluators should consider separately the risk for sexual and nonsexual recidivism.     

Psychopathic traits,gender, and motivations for sex: Putative paths to sexual coercion

Evidence suggests that both men and women perpetrate sexual coercion. Psychological factors, including psychopathic traits and power motivations, have been proposed to characterize male-perpetrated sexual coercion; however, it is unclear whether these factors play a similar role in female-perpetrated coercion or whether other motivations (e.g., intimacy, affect regulation) should be considered. To improve our understanding in this area, the current study first examined relationships between psychopathic traits and sexual coercion in a sample of 1199 undergraduate students (756 women), with gender as a potential moderator of these relationships. Second, the role of motivations for sex (e.g., power, affect regulation) in accounting for the psychopathy-coercion relationship was examined in men and women. Data were collected using an online survey and analyzed using multigroup path analysis. Results implicated impulsive-antisocial traits as particularly important to male-perpetrated verbal (e.g., manipulative) and nonverbal (e.g., physical) coercion, and that this relationship was partially explained by motives for sex involving power. In contrast, psychopathic traits did not appear to play a major role in female perpetrated coercion; instead, emotional value (i.e., intimacy-related) motivations for sex were associated with verbal (e.g., manipulation) coercion in women. In sum, our results support a conceptual model of male perpetration where men who are high in impulsive-antisocial traits may engage in sexual coercion in an attempt to feel powerful. Further, the findings in the female sample suggest that factors other than psychopathy, such as gender role beliefs in regard to sexual encounters, may be particularly important to female perpetrated sexually coercive behavior.     

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.     

Beyond targets: consequences of vicarious exposure to misogyny at work

The present study tested a model examining 2 indicators of a hostile interpersonal workplace climate for women-observed hostility (i.e., incivility and sexual harassment) toward women and perceived organizational unresponsiveness to sexual harassment--and how they relate to well-being and withdrawal for employees. Participants included 871 female and 831 male employees from a public university. According to structural equation analyses, observing hostility toward women and perceiving the organization as lax about harassment predict lower well-being, which translates into higher organizational withdrawal for both female and male employees. Results hold even after controlling for personal mistreatment, negative affectivity, and observed hostility toward men. These findings suggest that working in a misogynistic environment can have negative effects for all employees.     

From Gaze to Outrage: The Role of Group-Based Anger in Mediating the Relationship between Sexual Objectification and Collective Action

Numerous studies have demonstrated the harmful effects of sexual objectification on well-being. However, despite the rapid growth of the #MeToo movement, which has raised public awareness about sexual harassment, there has been much less research investigating the role of sexually objectifying behaviours in motivating people to try to tackle this issue through collective action (e.g., signing petitions, engaging in protests) and the process through which this occurs. Across two studies, we tested whether experiencing sexually objectifying behaviours motivates women to be willing to engage in collective action against sexual objectification via feelings of anger toward women being the target of such actions (i.e., group-based anger). In Studies 1 (n?=?127) and 2 (n?=?159), female participants rated the extent to which they had been the target of sexually objectifying behaviours, their feelings of group-based anger, and their willingness to engage in collective action against sexual objectification. We found that sexual objectification positively predicted the willingness to engage in collective action and that this relationship was mediated by feelings of group-based anger. This pattern suggests that experiencing numerous instances of sexual objectification is likely to result in women feeling group-based anger and that this anger, in turn, promotes collective action against sexual objectification. Therefore, our research demonstrates one process through which sexual objectification promotes a willingness to engage in collective action.

     

Deviant sexual arousal,offense history,and demographic variables as predictors of reoffense among child molesters

The present study examined selected demographic and offense history variables and deviant sexual arousal as predictors of reoffense in a group of 35 untreated child molesters. The measure of deviant sexual arousal was based on laboratory measures of sexual preference using penile plethysmography. Factor analysis of the predictor variables yielded three factors. The measure of deviant arousal, the amount of force used in the offense, whether or not the offender had intercourse with the child victim, and the number of previous victims loaded on the first factor, called Sexual Deviance. IQ and socioeconomic status loaded on the second factor, called Social Status. Age of the offender and age of the victim loaded on the third factor, called Offender Age. Entering the sets of three factor scores as predictors in a multiple correlation, over 20% of the variance in recidivism was explained, but the factor Sexual Deviance was the only significant predictor of recidivism (p < .02). Almost 30% of the variance in number of reoffenses was explained, and both Sexual Deviance (p < .01) and Social Status (p < .10) were significant predictors. A cluster analysis identified a group of offenders characterized by low SES and low IQ who also showed higher sexual deviance scores and a high rate of reoffense.     

Religiosity, Alcohol Use, and Sex Behaviors Among College Student-Athletes

College student-athletes tend to consume more alcohol, engage in sex, and report more sex partners than nonathlete students. The current study examined the relationship between religiosity (e.g., influence of religious beliefs and church attendance) and alcohol use and sex behavior among college student-athletes. Most of the student-athletes (n = 83) were religious. Influence of religious beliefs was a significant predictor of less alcohol use and less sexual activity (i.e., oral and vaginal sex, number of sex partners). However, increased church attendance was not found to be a protective factor. Findings suggest that religious beliefs may contribute to reduction of alcohol use and sexual risk among college student-athletes. Consideration should be given to incorporating religiosity aspects in sexual and alcohol risk-reduction interventions for student-athletes.     

Social Identity Orientation and the Generation of Compensatory Expectations: Schema Maintenance Through Compensation

This research explored the role that motives to confirm or maintain group stereotypes play in forming expectations about the future behaviors of ingroups. Participants who were high and low in social identity orientation (SIO) were presented with inconsistent information about the behavior of a member of their cohort group (i.e., college students). They then made predictions about the future behavior of either the deviant student (same target) or another student who was unrelated to the deviant (different target). High SIO participants, who should be especially motivated to confirm or maintain their group concept, generated compensatory expectations about the future behavior of a different group member who was unrelated to the deviant. Participants who were low in SIO did not demonstrate these effects. These results extend previous work (Seta & Seta, 1993) by demonstrating the moderating role of individuals' motivation to maintain group concepts. Results were also discussed in relation to Steele's research on self-affirmation (e.g., Steele & Lui, 1983) and our analysis of schema maintenance through compensation.     

Neurodevelopmental and psychosocial risk factors in serial killers and mass murderers

Multiple and serial murders are rare events that have a very profound societal impact. We have conducted a systematic review, following PRISMA guidelines, of both the peer reviewed literature and of journalistic and legal sources regarding mass and serial killings. Our findings tentatively indicate that these extreme forms of violence may be a result of a highly complex interaction of biological, psychological and sociological factors and that, potentially, a significant proportion of mass or serial killers may have had neurodevelopmental disorders such as autism spectrum disorder or head injury. Research into multiple and serial murders is in its infancy: there is a lack of rigorous studies and most of the literature is anecdotal and speculative. Specific future study of the potential role of neurodevelopmental disorders in multiple and serial murders is warranted and, due to the rarity of these events, innovative research techniques may be required.     

Serial killers: II. Development,dynamics, and forensics

Part I of this two-part article described the demographics, patterns, typologies, and motives of different subtypes of serial killers. Part II describes the development of the serial killer's drives and offense patterns. It discusses the brain mechanisms and dysfunctions that have been purported to underlie this type of extreme crime, as well as the cognitive, psychodynamic, and sociocultural factors that contribute to the development of the serial killer's relentless quest for victims. The article then discusses the practical forensic aspects of theories and knowledge about serial killers, specifically, the efficacy of behavioral profiling of offenders and the relevance of the insanity defense to serial killer cases.     

Development of Adolescent Problem Behavior

The developmental model of adolescent antisocial behavior advanced by Patterson and colleagues (e.g., Patterson, Reid, & Dishion, 1992) appears to generalize the development of a diverse set of problem behaviors. Structural equation modeling methods were applied to 18-month longitudinal data from 523 adolescents. The problem behavior construct included substance use, antisocial behavior, academic failure, and risky sexual behavior. Families with high levels of conflict were less likely to have high levels of parent–child involvement. Such family conditions resulted in less adequate parental monitoring of adolescent behavior, making associations with deviant peers more likely. Poor parental monitoring and associations with deviant peers were strong predictors of engagement in problem behavior. These constructs accounted for 46% of the variance in problem behavior. Although association with deviant peers was the most proximal social influence on problem behavior, parental monitoring and family factors (conflict and involvement) were key parenting practices that influenced this developmental process.

Religiosity Reduces Sexual Aggression and Coercion in a Longitudinal Cohort of College Men: Mediating Roles of Peer Norms,Promiscuity, and Pornography

Extensive literature suggests that religiosity is a protective factor in reducing a number of deviant behaviors, including sexual aggression (SA). Whereas previous research focused on the role of risky alcohol consumption in mediating the relationship between religiosity and SA, this study explores the hypothesized meditational paths from religiosity to SA and technology‐based coercive behavior (TBC) through peer norms, pornography consumption, and promiscuity. Findings from a four‐year longitudinal study of male college students suggest that peer norms and promiscuity mediate the relationship between religiosity and both outcome measures, while pornography consumption mediates the relationship between religiosity and TBC. These findings may inform ongoing practice and future research into possible mechanisms by which problematic sexual behaviors may be influenced.     

The effects of masturbatory reconditioning with nonfamilial child molesters.

Abel and Annon's (Reducing deviant sexual arousal through satisfaction, Denver, Colo., 1982) suggested combination of 'directed masturbation' and 'satiation' to alter deviant sexual preferences, was applied to 10 nonfamilial child molesters. Post-treatment assessments revealed significant reductions in deviant arousal as was expected, but unfortunately there were also reductions in appropriate arousal although these changes did not achieve statistical significance. The results are discussed in terms of their meaning but it is concluded that empirical support for these clinically popular procedures remains weak.     

Creativity and Ethics: The Relationship of Creative and Ethical Problem-Solving

Students of creativity have long been interested in the relationship between creativity and deviant behaviors such as criminality, mental disease, and unethical behavior. In this study we wished to examine the relationship between creative thinking skills and ethical decision-making among scientists. Accordingly, 258 doctoral students in the health, biological, and social sciences were asked to complete a measure of creative processing skills (e.g., problem definition, conceptual combination, idea generation) and a measure of ethical decision-making examining four domains: data management, study conduct, professional practices, and business practices. It was found that ethical decision-making in all four of these areas was related to creative problem-solving processes with late-cycle processes (e.g., idea generation and solution monitoring) proving particularly important. The implications of these findings for understanding the relationship between creative and deviant thought are discussed.     

Of Rats and Women: Fetal Sexuality and Hybrid Agency

This paper investigates the way in which the sexuality of women has been posited in relation to rats as experimental subjects, exploring the stakes of a scientific debate that takes the social world of female sexuality as its focus and as a political problem. Studies that purport to understand female sexuality by investigating rat behavior rely on problematic assumptions about sovereign agents motivating sexual behavior. Such studies also aim to do away with so-called deviant sexual behaviors and, as a consequence, gay people. Theories of agential realism and hybridity serve as counterforces to these inherently repressive perspectives by insisting on the multiple determinations of sexuality and subjectivity among women.
