“…Multiple other mechanisms explaining specifically primary (but not secondary) transfer effects of positive contact have been identified. These comprise affective variables such as different intergroup emotions (e.g., anger: Barlow et al, 2019;disgust and admiration: Cernat, 2011;fear: Kauff et al, 2017;Seger et al, 2017) and numerous cognitive processes (e.g., knowledge about the outgroup: Brown & Hewstone, 2005); social norms (perceptions of how ingroup members think and act: Christ et al, 2014;Paterson et al, 2019;Turner et al, 2008;Wang et al, 2019); inclusion of the other in the self (perceived closeness between the self and outgroup: Page-Gould et al, 2010;Turner et al, 2008); self-disclosure (disclosure of personal information about self to other: Frølund Thomsen, 2012;Turner, et al, 2007); dehumanization or infrahumanization (denying elements of humanness to outgroups: Prati & Loughnan, 2018;Stathi et al, 2017); perceived importance of and satisfaction with contact (Frias-Navarro et al 2020;van Dick et al, 2004); perceived outgroup heterogeneity (perception of similarity between outgroup members: Čehajić et al, 2008); stereotypes of outgroup warmth and competence (Kotzur et al, 2019;Zingora et al, 2020); and metastereotypes (beliefs about the stereotypes that outgroup members hold about their group: Mazziotta et al, 2011). It is plausible to expect many of these processes (e.g., emotions, social norms, outgroup evaluations) to generalize from primary to secondary outgroups and thus underlie not only the primary but also secondary transfer effects.…”
