“…Although there are contexts in which positive sanctioning of aggressive behavior is evident, such that peer group norms promote or reward aggressive behavior, for example, when highly aggressive peer groups reinforce continued aggression (e.g., Kuppens et al, 2008;Thomas et al, 2006) or when popular adolescents use relational aggression to further their status (e.g., Cillessen & Rose, 2005;Juvonen et al, 2003;Rodkin et al, 2006), in early adolescent peer groups, aggressive behavior is often negatively sanctioned. Indeed, a diverse body of literature has supported that aggressive behavior is associated with peer victimization and rejection (e.g., Bass et al, 2016;Ostrov, 2010;Santo et al, 2017;Velasquez et al, 2010Velasquez et al, , 2016. Moreover, social regulation of aggressive behavior is seen across age groups and cultures (e.g., Bass et al, 2016;Ostrov & Godleski, 2013;Santo et al, 2017;Velasquez et al, 2016), demonstrating a relatively universal peer group dynamic.…”
