Trophy, souvenir, or simple theft? Taking items from the victim in sexual homicide.

Although most people have heard the terms 'souvenirs', 'trophies', and 'mementos', discussed in books and movies on the true crimes of sexual murderers, limited research has delved into the phenomenon of theft in sexual homicide (SH). Using a sample of 762 SH cases coming from the Sexual Homicide International Database, the current study examines the crime-commission process of the pre-crime, crime, and post-crime phases of sexual homicide offenders (SHOs) who engaged in theft during a SH. Additionally, this study seeks to determine if a specific type of SHO engages in this behaviour over others. Results from the sequential logistic regression indicate that victims who are 16 years or older, were strangers to the SHO, and were sex workers were more likely to be victims of theft. Additionally, results indicate that the presence of sadism made it more likely the SHO would engage in theft from the victim and/or crime scene. Findings suggest there is a group of SHOs who engage in theft not for monetary purposes but due to the paraphilia of the offender. These findings can inform the police investigation of these crimes.

Correlates of the Dark Tetrad.

This study explored demographic, ideological, self-rating and personality traits correlates of the Dark Tetrad (DT4) which measures Narcissism (Special), Machiavellianism (Crafty), Psychopathy (Wild), and Sadism (Mean) traits. In total, 447 adults completed three tests: a bright-side, work-related, personality test (HPTI: High Performance Type Indicator), a dark-side test (Short Dark Tetrad) and a number of self-ratings. Correlations and regressions showed that all four dark traits were associated with low Adjustment (Neuroticism), but also with high Risk-Taking and Competitiveness (low Agreeableness). The various measures accounted for a third of the variance in explaining the Mean (Sadistic) score, and 40 % for Special (Narcissism). Trait Competitiveness was most closely associated with all four dark traits.

Sadism in the context of intergroup aggression.

People more readily harm members of outgroups than ingroups, often enjoying the inflicted agony. Yet it remains unclear how these malevolent tendencies towards outgroups relate to sadism. Sadists often harm others, driven by a desire to feel pleasure from their suffering. In attempt to bridge these two lines of research, this work examined relationships between sadism and aggression against ingroup and outgroup members in three studies (total N = 755) that focused on two groups with a history of conflict (i.e., the United Kingdom and the Republic of Ireland). Across all studies, British participants' sadistic tendencies were just as strongly linked to their aggression against ingroup members (i.e., British partners) as to their aggression against outgroup members (i.e., Irish partners). Despite this lack of a preference for greater outgroup aggression, they tended to enjoy outgroup aggression more than ingroup aggression, especially at its extreme levels. These findings extend works linking sadism to aggression into the domain of intergroup relations and bind together research on sadism and intergroup schadenfreude.

Anxiety, Desire, and the Object a: Lacan on Lucia Tower's "Countertransference".

Lacan's seminars are a treasure trove of innovative psychoanalytic explorations. In Seminar X, Anxiety, he takes up this Freudian theme and explores a number of interrelated ideas: castration, the difference between the sexes, two different forms of acting out, and what he terms his only original theoretical contribution: the object a and its "various incidences." The object a is described here in detail, especially in relation to Lacan's argument that analysts who are women have a freer relationship to their desire and the countertransferences it spawns than do men. Lacan discussed Lucia Tower's classic paper, "Countertransference," in light of these notions. This essay is a close reading of Lacan's close reading of Tower, whose account, he says, must be approached in all its "innocence and freshness."

Sexual violence, deviance, and the paraphilias in American psychiatry, 1952-2013.

This article explores arguments within American psychiatry from the 1950s around whether rapists were mentally ill. It analyses debates in the lead-up to the various editions of the American Psychiatric Association's (APA's) Diagnostic and Statistical Manual of Mental Disorders (DSM) from 1952 to the latest version in 2013, focussing particularly on a diagnostic category called 'Paraphilic Coercive Disorder' (PCD). Since the first DSM, American psychiatrists had routinely considered people who committed certain forms of sexual violence to be suffering from mental disorders. For example, 'Paedophilia' and 'Sexual Sadism' had always been considered valid diagnoses. However, the APA refused to pathologise non-sadistic sexual violence committed against adults. Opposition can be classified into four overlapping arguments: uncertainty about 'normal' male sexual aggression, feminist worries about 'excusing' harmful sexual behaviours, concerns about the misuse of psychiatry in courts, and the need to defend the psychiatric profession from encroachments on their 'territory' by non-medically trained psychologists, social workers, and anti-psychiatric activists.

A functionalist approach to online trolling.

Online trolling is often linked to sadism and psychopathy. Yet, little research has assessed why people high in these traits seek online environments to achieve their nefarious goals. We employ a functionalist approach to examine whether people high in sadism and psychopathy are motivated to seek the affordances of online environments (e.g., anonymity) to reveal their malevolent self-aspects by engaging in trolling behavior. A sample of 515 university undergraduates (Mage = 20.47) read vignettes depicting trolling incidents and rated the acceptability of the perpetrators' actions and whether they had ever written similar comments. Participants then completed measures of psychopathy, sadism, and toxic anonymous motivations. We find that toxic anonymous motivations partially mediate the relationship between psychopathy and sadism, and online trolling. Whereas trolling is often understood through its underlying personality traits, toxic motivations to seek anonymity may be a more proximal predictor of who is likely to troll online.

Sadism and Personality Disorders.

PURPOSE OF REVIEW: Sadistic pleasure-the enjoyment of harm-infliction to others-can have devastating interpersonal and societal consequences. The goal of the current review is to illuminate the nomological net of traits related to sadism. We aim to achieve an understanding of the current empirical status on the link between sadism and personality disorders, psychopathy, the Dark Triad, and basic personality traits in clinical and community-based samples. RECENT FINDINGS: The field is dominated by self-report studies on the Dark Triad with convenience samples. The link with DSM personality disorders has hardly been empirically studied. Existing evidence shows that sadism is most strongly related to increased psychopathic personality traits. Sadism can originate both from the interpersonal, affective, and behavioural basis of dark personality traits. There are diverging ideas on the differential status between sadism, psychopathy, and other dark traits. Research is needed on the causal impact of the broader range of personality disorders on sadism, in more diverse samples, including behavioural assessments of sadistic pleasure, as well as on the interplay of such personality traits with situational and affective aspects, and victim attitudes.

Exploring Substance Abuse and the Dark Tetrad in Health Sciences and Non-Health Sciences Students.

Substance abuse can be used as a coping strategy to manage stress related to academic activities and is a risk-taking behavior that is also associated with people with higher levels of the Dark Tetrad personality traits. Our study aimed to investigate the association between substance abuse and the Dark Tetrad in students in health and non-health sciences fields. Our sample was composed of 174 college students between 18 and 58 years old (M = 25.60; SD = 9.14). Students completed self-report psychopathy, narcissism, Machiavellianism, sadism, and substance use scales. Results suggest that men consumed more substances and scored higher on the Dark Tetrad than women. Also, when comparing fields, men from health sciences tended to score higher on dark personality traits. These results emphasize the potential risk factors associated with dark personality traits and the consumption of licit and illicit substances by college students, highlighting the need for further studies with this population and the impact of these behaviors and characteristics on future professional practice.

Everyday Sadism as a Predictor of Rape Myth Acceptance and Perception of Harassment.

The #MeToo movement has stressed the need to understand why individuals who witness sexual violence may or may not take action. However, prevention programs usually fail to address the association between personality traits and attitudes, perception, and behavior in the context of sexual violence. To improve prevention programs' effectiveness, it is vital to understand how personality traits might interfere with willingness to engage in bystander intervention. This study aims to explore the relationships between Everyday Sadism, perception of harassment, Rape Myths and gender in a sample of 177 participants recruited online. Analyses revealed significant gender differences, with men endorsing more Rape Myths, perceiving less harassment, and being more sadistic. Gender and everyday sadism emerged as significant predictors of perception of harassment. In the case of Rape Myths, age emerged as an additional predictor. These results have several implications, ranging from expanding our knowledge of the influence of everyday sadism on factors known to modulate bystander behaviors as well as informing and shaping the development of prevention programs.

Cannibalism-overview and medicolegal issues.

Cannibalism, the consumption of another by an individual of the same species, is a widespread practice amongst many animal groups. Human cannibalism or anthropophagy, however, is less common but has been found in many diverse groups ranging from hominids to Crusaders and soldiers in World War II. Although the existence of human cannibalism has been vigorously debated in recent times, it seems clear that well-described cases have occurred. The motivation for consuming human tissues may be (1) nutritional, (2) ritual and (3) pathological. A case of alleged cannibalism involving one of the victims of the so-called Snowtown serial killings in South Australia, Australia, is reported with an analysis of the history and features of cannibalism. Forensic problems may occur in accurately identifying remains that have been cannibalized; however, if ritualistic, serial and/or sadistic homicides are encountered, cannibalism should be considered, particularly if body parts are missing.

Emotional intelligence in incarcerated sexual offenders with sexual sadism.

Emotional intelligence (EI) is defined by the ability to perceive, manage, and reason about emotions in oneself and others. Studies have reported deficits in EI abilities among certain antisocial populations such as individuals with psychopathy, and enhanced performance among sexual offenders. Despite EI's relevance to offending behaviour, the association between EI and paraphilic offending has been under-studied. We examined the association between EI, sexual offending, and sexual sadism in 80 incarcerated men with sexual offenses and 207 incarcerated men with non-sexual offences. EI was assessed using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Sadism was measured using the Severe Sexual Sadism Scale (SeSaS). Results showed that SeSaS scores were positively associated with Strategic EI (the ability to understand and manage emotions), but were not significantly related to Experiential EI. This may reflect core characteristics of sexual sadism including domination and manipulation, challenging the prevalent notion that higher EI is invariably positive.

Serial sexual murder by juveniles and the role of sexual sadism: An international study.

This is a descriptive study of 21 cases of serial sexual murder by children and adolescents spanning nearly the past century and a half. No earlier cases worldwide were identified. Each of these youth committed two or more sexual homicides prior to age 18. Their psychopathological, psychosocial, crime scene behaviors, and offender-victim relationship characteristics are presented. Additionally, the role of sexual sadism and its measurement using the SADSEX-SH rating scale is addressed. Nearly all of the sample had conduct disorder, a paraphilic disorder, and sadistic fantasies, and two-thirds had sexual sadism disorder. Family dysfunction, serious school problems, and average or above IQ levels were typical. Their modus operandi generally reflected predatory behavior and direct contact methods of killing were most common. Two case reports are provided to illustrate the breadth and complexity of these offenders. Juvenile Serial Sexual Homicide is an extremely rare but persistent phenomenon. Prognostic implications and future research directions are discussed.

Childhood Trauma Predicts Sadistic Traits and Violent Behavior in Incarcerated Youth.

Childhood trauma exposure is prevalent among incarcerated youth and associated with antisocial traits and behavior. It has been proposed as a risk factor for the development of sadistic traits, which has been shown to predict future violence in youth. Using regression analyses, we examined the association between self-report and expert-rated measures of childhood trauma, sadistic traits (i.e., verbal, physical, vicarious sadism), and violence (i.e., homicide and non-homicide violent acts) in 54 incarcerated juveniles. Expert-rated (but not self-report) severity of physical abuse was associated with physical and vicarious sadistic traits. Other trauma types (e.g., emotional or sexual abuse) were not significantly associated with sadistic traits. Physical abuse coupled with vicarious sadistic traits conferred the highest risk of non-homicide violence. The findings support and clarify links between childhood trauma, sadistic traits, and violent behavior in youth, and are distinct from those found in other antisocial profiles.

Strangulation in sexual homicide: Is it opportunity, victim's vulnerability or sadism?

Although most homicides involve the use of a weapon, some offenders still prefer killing with their own hands, using strangulation. In fact, when disaggregating the various types of homicides, sexual homicide offenders appear as having a preference for "personal weapon" to kill the victim. Personal weapons, such as strangulation, asphyxiation, and beating, are the most commonly used killing methods in sexual homicide. Using a sample of 451 cases of sexual homicide of adult female, the current study examines three hypotheses as to why strangulation is the method of choice to kill in sexual homicide: 1) weapon of opportunity, 2) victim's vulnerability, and 3) sexual sadism. Results from logistic regressions and artificial neural network analysis show that all three hypotheses are supported, sexual homicide offenders using strangulation being less likely to target a victim with a strong build, to bring and use a weapon. However, strangulation is more likely to be used to kill the victim when the offender is characterized with sadism. Implications of the findings are discussed in light of our understanding of the crime-commission process involved in sexual homicide.

Is "sadistic pleasure" a contrived process of signaling one's antagonism?

OBJECTIVE: Sadistic pleasure presumably incorporates processes that support an authentic enjoyment of others' pain. However, antagonism confirmation theory, grounded in social-psychological theorizing on identity maintenance and the notion of ego-syntonicity, suggests that individuals higher in sadism report greater pleasure in response to others' pain because such reports are immoral responses that confirm their self-views. This alternative conception has yet to be tested. METHOD: In two preregistered experiments (total N = 968), participants completed measures of sadism, read about situations involving others' pain, and rated their pleasure. We manipulated the extent to which pleasure from others' pain could be used to signal morality or antagonism. RESULTS: We found that relatively sadistic people indicated greater pleasure across the studies but, like relatively non-sadistic people, they altered their pleasure ratings to signal greater morality or less antagonism. CONCLUSIONS: The findings fail to support antagonism confirmation theory, but they support recent perspectives on sadism that suggest that sadistic people may occasionally care about seeming moral (or not seeming antagonistic) and that sadism may be somewhat ego-dystonic in this respect.

Development and validation of Chinese form Short Dark Tetrad (C-SD4).

The Short Dark Tetrad (SD4) was developed as a brief measure of the Dark Tetrad, which comprises narcissism, Machiavellianism, psychopathy, and sadism. Previous research suggests the possibility of cultural differences in these traits in Western and Eastern cultures. We developed and validated the Chinese form of SD4 (C-SD4) cross four studies in a large sample (total N = 3181) to assist in solving problems caused by these differences. In study 1, we adjusted the item pool on the basis of the original form of SD4. In Study 2, we trimmed the scale to generate a 28-item version of C-SD4 and examined correlations with Big-5. In study 3, we examined the internal structure, measurement invariance, and criterion validity of the C-SD4. In study 4 we examined C-SD4 test-retest reliability and compared item content to standard measures. This package of studies suggests that the C-SD4 is a reliable and valid measure of the Dark Tetrad in Chinese participants.

Non-angry aggressive arousal and angriffsberietschaft: A narrative review of the phenomenology and physiology of proactive/offensive aggression motivation and escalation in people and other animals.

Human aggression typologies largely correspond with those for other animals. While there may be no non-human equivalent of angry reactive aggression, we propose that human proactive aggression is similar to offense in other animals' dominance contests for territory or social status. Like predation/hunting, but unlike defense, offense and proactive aggression are positively reinforcing, involving dopamine release in accumbens. The drive these motivational states provide must suffice to overcome fear associated with initiating risky fights. We term the neural activity motivating proactive aggression "non-angry aggressive arousal", but use "angriffsberietschaft" for offense motivation in other animals to acknowledge possible differences. Temporal variation in angriffsberietschaft partitions fights into bouts; engendering reduced anti-predator vigilance, redirected aggression and motivational over-ride. Increased aggressive arousal drives threat-to-attack transitions, as in verbal-to-physical escalation and beyond that, into hyper-aggression. Proactive aggression and offense involve related neural activity states. Cingulate, insular and prefrontal cortices energize/modulate aggression through a subcortical core containing subnuclei for each aggression type. These proposals will deepen understanding of aggression across taxa, guiding prevention/intervention for human violence.

I'm Offering You My Pain: Priming COVID-19 Salience Increases Everyday Sadism.

The COVID-19 pandemic and its link to the emergence of everyday sadism is a matter of public concern worldwide. However, previous studies are nearly silent regarding the causal relationship between the two variables. We address this gap by theorizing that exposure to information about coronavirus can increase sadistic behavior by inducing state boredom. We conducted three complementary controlled experiments, which comprised multiple participants populations (N = 784, student and community samples) and measurement techniques of sadism, to test our theoretical perspective. Based on self-report measures, Study 1 found that Chinese university students who were exposed to a reminder of COVID-19 exhibited a higher level of everyday sadism than participants in the control condition. Study 2 replicated this finding in a more generalized population. Additionally, results revealed that state boredom mediated this effect. Moving beyond subjective self-report data in Studies 1 and 2, Study 3 assessed a different behavioral operationalization of sadistic tendencies, namely, shredding worms. As expected, priming COVID-19 salience has an immediate, statistically significant influence on sadistic behavior in impactful real-world contexts. Overall, these findings suggest that the COVID-19 pandemic not only has grave effects on economy and society, but has implications for the malevolent side of human nature.

I enjoy hurting my classmates: On the relation of boredom and sadism in schools.

Schools can be a place of both love and of cruelty. We examined one type of cruelty that occurs in the school context: sadism, that is, harming others for pleasure. Primarily, we proposed and tested whether boredom plays a crucial role in the emergence of sadistic actions at school. In two well-powered studies (N = 1038; student age range = 10-18 years) using both self- and peer-reports of students' boredom levels and their sadistic tendencies, we first document that sadistic behavior occurs at school, although at a low level. We further show that those students who are more often bored at school are more likely to engage in sadistic actions (overall r = .36, 95% CI [0.24, 0.49]). In sum, the present work contributes to a better understanding of sadism in schools and points to boredom as one potential motivator. We discuss how reducing boredom might help to prevent sadistic tendencies at schools.

The Third Backdoor: How the DSM Casebooks Pathologized Homosexuality.

This study argues that institutional psychiatry's pathologizing stance on homosexuality persisted after 1973, when the American Psychiatric Association removed homosexuality from the Diagnostic and Statistical Manual of Mental Disorders. It persisted not only through the well-known diagnoses of "ego-dystonic homosexuality" and "gender identity disorder of childhood," but also through case studies published in four editions of the DSM Casebooks (1981, 1989, 1994, 2002), the APA publications advertised as a "learning companion to the Diagnostic and Statistical Manual." These publications contained harmful and false homosexual stereotypes, associating gay men with child abuse, violence, and sexual sadism; associating homosexuality with mental disturbance while failing to similarly mark heterosexuality or bisexuality; associating psychopathology with gay social contexts while failing to similarly mark non-gay social contexts. This study provides evidence that the DSM Casebooks portrayed homosexual women and bisexuals as invisible, and homosexual men as narcissistic, predatory, and dangerous.
