Aggressive Behavior最新文献

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.

Early childhood relationships with teachers, parents, siblings, and peers are foundational factors for later social functioning. High rates of childhood aggression have been associated with negative developmental consequences, however, the associations between child aggression on the quality of these formative relationships have not been studied extensively. In a sample of young children attending preschool (N = 114, Mage = 46.27 months, SD = 9.94, 40% girls), this study investigated associations between early childhood relational and physical aggression and the quality of concurrent teacher-child and parent–child closeness and conflict, sibling relationship quality, and positive peer interactions and peer rejection. Early childhood relational and physical aggression was associated with negative teacher–child relationships, and this was true for boys and girls. Differential patterns of prediction were found for relational and physical aggression on the other relationship variables. Relational aggression strongly predicted more positive peer interactions, whereas physical aggression predicted fewer positive peer interactions and greater peer rejection. Early childhood relational aggression predicted higher levels of teacher-child closeness, whereas physical aggression predicted lower levels of teacher–child closeness and fewer positive sibling interactions. These findings challenge common perceptions that aggression is negatively associated with relationship quality. Notably, relational aggression relative to physical aggression may be associated with some favorable relationship outcomes. We did not find support for an additive model of aggression whereby children who were both relationally and physically aggressive (co-morbid) were at higher risk for negative relationship quality. Implications of these findings for future research and prevention and intervention are discussed.

How do daily fluctuations in aggression relate to daily variability in affect and self-esteem? Although research has examined how trait aggression relates to affect and self-esteem, state aggression has received little attention. To this end, we had 120 US undergraduates participate in a 14-day daily diary study where they responded to state-level measures of aggression, affect, and self-esteem. Crucially, we used multifaceted state measures of both aggression (anger, hostility, verbal aggression, physical aggression) and affect (positive vs. negative, activated vs. deactivated). Multilevel models revealed that daily anger and hostility related positively to daily negative affect and negatively to daily positive affect. Similarly, daily anger and hostility related negatively to daily self-esteem. In contrast, daily verbal and physical aggression were largely unrelated to daily affect and self-esteem; however, unexpectedly, daily physical aggression related positively to daily positive activated affect, but only when controlling for the other daily aggression domains. Overall, daily attitudinal aggression measures—anger and hostility—related to daily affect and self-esteem in theoretically consistent ways, whereas daily behavioral aggression measures—verbal and physical aggression—did not. Our findings support expanding the General Aggression Model to incorporate state-level processes.
