Although peer norms significantly influence adolescents' aggressive behaviors, little research compares their effects in online and offline contexts. Specifically, online contexts differ from traditional ones by enabling anonymity and amplifying behavior visibility. These characteristics could alter norm perceptions, reducing or increasing…

This longitudinal study investigated whether classroom norm salience toward aggression moderated the association between parental education and children's overt aggressive behavior development from third to sixth grade of elementary school. Children (N = 1,205, 51% girls) from 46 Dutch elementary schools were annually followed from third to sixth…

The impact of aggressive humor on workplace dynamics has been extensively examined; however, its implications for university students remain underexplored. Drawing on frustration--aggression theory, this study aims to uncover the consequences of peer-aggressive humor and its relationship with cyberbullying behavior. We employed a 2 (peer…

This exploratory study aims to broaden students' models of cyber-aggression behavior, with the Theory of Planned Behavior (TPB) by including additional constructs, namely cyber health, to predict youth cyber-aggression actions. The self-administered questionnaire was used to collect data from 291 students intentionally, aged 15 to 21 at secondary…

This study examined variations in the development of classroom aggression popularity norms, as well as the role of homeroom teachers' aggression beliefs and students' perceptions of teachers' support as predictors of such variations. To achieve this goal, a sample of 63 classrooms were assessed at four time points during a school year, in nine…

For decades, research summarizing educational outcomes has indicated significant disparities, which continue to impact the academic achievement and wellbeing of Black students in Ontario. These concerns are further amplified due to the lack of disaggregated educational data, making it difficult to outline and address disparities for specific…

The goal of this study was to examine behavioral norm effects in 2 peer contexts (classroom, school) on adolescent substance use (tobacco, alcohol, cannabis) and aggressive behaviors (bullying, physical fighting). Participants were 5,642 adolescents (M[subscript age] = 14.29 years, SD = 1.26; 49% boys). There were 3 hypotheses. First, behavioral…

This study examines behavioral norms, moral judgments, and social approval of participant roles in classroom physical, verbal, and relational bullying, including a relatively new reporter role (where nothing is done during the bullying but there is subsequent reporting to a teacher). A sample of 1,131 Secondary 1 (mean age = 12 years 7 months) and…

The purpose of the present study was to examine the relation between narcissistic orientations (grandiose sense of self-importance, interpersonal exploitation, and narcissistic rage) and relational aggression (self-satisfactory and punishment type) and the mediating effects of guilt feelings toward and perceived classroom norms against relational…

Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the…

The phenomenon of harassment in Russian universities creates an environment that can be both threatening to the individual and a source of poor performance by the work group.

The School Normative Context entails two new…
