In this study, using the self/other adjective judgment task, we aimed to explore how people perceive themselves in comparison to various other people, including friends, strangers, and those they dislike. Next, using representational similarity analysis, we sought to elucidate how these perceptual similarities and differences are represented in brain activity and how aggressiveness is related to these representations. Behavioral ratings show that, on average, people tend to consider themselves more like their friends than neutral strangers, and least like people they dislike. This pattern of similarity is positively correlated with neural representation in social and cognitive circuits of the brain and negatively correlated with neural representation in emotional centers that may represent emotional arousal associated with various social objects. Aggressiveness seems to predispose a person to a pattern of behavior that is the opposite of the average pattern, that is, a tendency to think of oneself as less like one's friends and more like one's enemies. This corresponds to an increase in the similarity of the behavioral representation with the representation in the emotional centers and a decrease in its similarity with the representation in the social and cognitive centers. This can be seen as evidence that in individuals prone to aggression, behavior in the social environment may depend to a greater extent on the representation of social objects in the emotional rather than social and cognitive brain circuits.

Youth violence continues to be widespread. Despite numerous evidence-based programs that reduce youth violence, objective ways to identify youth in need of services is lacking. Few screening tools are available that enables practitioners or community organizations to predict who may perpetrate serious violence. The Violence Injury Protection and Risk Screen (VIPRS) is a previously validated screening tool providing a framework to address youth violence. The purpose of this study is to evaluate the psychometric properties of the VIPRS in a community sample for use in multiple settings. Youth participating in a community-focused youth violence prevention intervention served as the study subjects. Households with youth ages 10−17 were eligible to participate. Study personnel verbally asked youth survey questions and recorded answers on a laptop. Multiple measures—including risk factors for violent behavior as well as, violence and delinquency scales, were asked. Eleven hundred youth participated. Mean age was 13.3; 53% female, 26% Black, 58% Hispanic, 11% more than 1 race. Twenty percent screened positive on the VIPRS—28% male versus 13% female (p = .000). Violence-related behaviors were common: 33% were in a physical fight, 27% experienced cyberbullying victimization, and 9% perpetrated a minor assault. The VIPRS demonstrated robust criterion validity with significant correlation to multiple violence measures (0.3−0.6). Scoring positive on the VIPRS conveyed increased odds of reporting other violent behaviors, such as perpetrating physical aggression (OR: 7 [95% CI: 5.1−11.5]). Overall, the VIPRS performed well in a community sample of youth further validating its psychometric functioning while demonstrating the potential for use in settings beyond healthcare.

Researchers of aggression have classically focused on what has been previously called active aggression—the deliberate infliction of harm through the direct application of deleterious consequences. However, the counterpart to this, what was originally called passive aggression, has gone understudied, and its definition has mutated beyond its original conceptualization. The present two studies (N's 196 and 220, respectively) attempted to examine passive aggression as originally defined—the deliberate withholding of behavior to ensure that a target is harmed—and renaming it aggression by omission (ABO), in contrast to aggression by commission (ABC). These studies found that both fit within a similar nomological network of antagonism, Sadism, and trait aggression. Study 2 additionally found that both were equally affected by provocation and were considered equally harmful. These findings encourage further research into ABO to capture this construct concretely, especially in the context of common paradigms (e.g., the Taylor Aggression Paradigm, Hot Sauce, Point-Subtraction Aggression Paradigm), and trait aggression scales, which typically measure ABC.

Radicalization is a process by which individuals are introduced to an ideological belief system that encourages political, religious, or social change through the use of violence. Here we formulate an obsessive-compulsive disorder (OCD) model of radicalization that links obsessive passion (OP; one of the best predictors of radical intentions) to a larger body of clinical research. The model's central tenet is that individual differences in OCD symptom severity could shape radical intentions via their influence on OP. Across four ideological samples in the United States (Environmental activists, Republicans, Democrats, and Muslims, N_total = 1114), we found direct effects between OCD symptom severity and radical intentions, as well as indirect effects of OCD on radical intentions via OP. Even after controlling for potential individual difference and clinical confounds (e.g., adverse childhood experiences, loss of significance, and substance abuse), these relationships remained robust, implying that OCD plays a significant role in the formation of violent ideological intentions and opening new avenues for the treatment and prevention of violent extremism. We discuss the implications of conceptualizing radicalization as an OCD-like disorder with compulsive violent tendencies and ideology-related concerns.

Intimate partner aggression (IPA) is a costly and incompletely understood phenomenon. Negative urgency, the tendency to act impulsively in response to negative affect, is predictive of IPA perpetration. Mindfulness, by virtue of its emphasis on nonreactivity to negative affect, is an opposing force to urgent tendencies that may mitigate the negative urgency-IPA link. Yet, no research to date investigates the interactive effects of negative urgency and mindfulness on IPA perpetration. Two studies were conducted that measured and manipulated multiple facets of mindfulness alongside measures of negative urgency and tendencies of IPA perpetration (combined N = 508 undergraduate students in monogamous intimate relationships). Counter to our preregistered predictions, we found that negative urgency's association with greater IPA perpetration increased at higher levels of mindfulness. These findings suggest that mindfulness may not be a protective factor against IPA perpetration for individuals higher in negative urgency, but rather may serve as a risk factor.

The study examined the relationship between mistrust and aggression from childhood to adulthood. The participants resided in Portugal and were tested during middle childhood (Mage = 7.5, SD = 0.81 years, n = 445, 240 male), preadolescence (Mage = 11.92, SD = 0.96 years, n = 431, 200 male), mid-adolescence (Mage = 14.70, SD = 0.91 years, n = 326, 201 male), late adolescence (Mage = 18.14, SD = 1.19 years, n = 410, 216 male), and adulthood (Mage = 26.56, SD = 1.13, years, n = 417, 197 male). Mothers reported the participants' mistrust during childhood and preadolescence on items from the Child Behavior Checklist. Aggression was assessed by standardized self-report measures at each age period. It was found that mistrust was associated with aggression during preadolescence and predicted changes in aggression to mid-adolescence and adulthood. The findings supported the conclusion that mistrust during preadolescence predisposes individuals to show aggression later in the life course.

The purpose of the current research was to test the dual processes involved in predicting cyberbullying perpetration in a sample of US parent−child dyads. The Barlett Gentile cyberbullying model (BGCM) posits how positive cyberbullying attitudes mediate the relationship between anonymity perceptions and cyberbullying perpetration; however, less is known about (a) whether this mediated link is significant for youth and adults alike, (b) if the strength of the relationships in the BGCM differ between youth and adults, and (c) the role of child (or parent) perceptions of their parent's (or child's) cyberbullying behavior has on cyberbullying. Two hundred US parent−child dyads completed measures to assess cyberbullying perpetration, cyberbullying attitudes, cyberbullying perceptions, and anonymity perceptions. Results showed support for BGCM postulates for parents and adolescents; however, the mediated relationship was stronger for youth than adults. Moreover, cyberbullying perceptions correlated strongly with cyberbullying attitudes and cyberbullying perpetration. Results are discussed in terms of theory and intervention applications.

Exposure to hate speech (HS) leads to desensitization of listeners. Yet, most evidence of this process has been obtained using self-report measures. In this paper, we examined desensitization to HS using an unobtrusive, psychophysiological measure. In an experimental electrocardiogram study (N = 56), we observed heart rate (HR) deceleration after reading comments that contained HS. This suggested a substantive psychophysiological reaction of participants to hateful comments. However, such HR deceleration was not observed among participants preexposed to HS. People exposed to hateful comments thus appeared to show different HR responses to HS compared to people who were not previously exposed to such comments. Consequently, not only does frequent exposure to HS influence an individual's beliefs as observed in earlier studies, but it also impacts psychophysiological reactions to derogatory language.

Previous studies have established relationships between the Dark Tetrad traits and sexual violence and its acceptance through myths about this type of violence. Sexual violence is positively associated with machismo, with sexist beliefs having been found to be linked with the Dark Tetrad and with the acceptance of sexual violence. Using a community sample comprising 362 adults between the ages of 18 and 70 (M = 35.6, SD = 14.3) and three self-report measures, this cross-sectional study aimed to explore the mediating role of sexual machismo in the relationship between each of the Dark Tetrad traits and the acceptance of sexual violence, both in the overall sample and by gender, as well as whether a significant variance in this acceptance is explained by the “dark” traits, sexual machismo, and gender. In the regression, sexual machismo (the male) gender, and only Machiavellianism were uniquely associated with the acceptance of sexual violence, and sexual machismo partially mediated the associations between the Dark Tetrad and the acceptance of sexual violence. These findings indicate that being male and higher in sexism is more closely linked with the acceptance of sexual violence than most Dark Tetrad traits. Moreover, the associations between the Dark Tetrad, sexual machismo, and the acceptance of sexual violence were stronger in men, consistent with the notion that these traits facilitate a “male” exploitive mating strategy, which likely also extends to victim-blaming and positive attitudes about sexual violence more broadly. Lastly, the results emphasize the pervasiveness of beliefs about male superiority over women and its relationship with victim-blaming even in women.
