“…Previous studies on the effect of ostracism on aggression have mainly focused on controlled processes in aggression, using self-report measures to assess aggressive tendencies or behaviors (e.g., Wirth, 2010, unpublished; Stenseng et al, 2014, Study 1; Wakim, 2015, unpublished; Poon et al, 2016, Study 2) and related moderating and mediating variables. For instance, aggressive response to ostracism may depend on factors such as: control deprivation (Warburton et al, 2006), rejection sensitivity (Ayduk et al, 2008), general just-world beliefs (Poon and Chen, 2014), nature exposure (Poon et al, 2016), and emotional-impulsive readiness for aggression (Rajchert et al, 2017). Further, DeWall et al (2009) demonstrated that the link between peer rejection and aggression is mediated by a hostile cognitive bias, and Reijntjes et al (2011) also supported this conclusion based on a study of early adolescence.…”
