“…What factors do enhance group identification? Jackson and Smith (1999) found four factors of group identification: Perception of the intergroup context such as antagonism or competition (Ellemers, Doosje, Van Knippenberg, & Wilke, 1992;Ellemers, Van Rijswijk, Roefs, & Simons, 1997), attraction to the ingroup such as similarity to group members or fair treatment (Brewer & Pickett, 1999;Brewer & Kramer, 1986;Tyler, Degoey, & Smith, 1996), interdependency belief and perceived common fate (Rabbie & Horwitz, 1969;Rosenbaum, Moore, Cotton, Cook, Hieser, Shover, & Gray, 1980), and depersonalization (Postmes, Spears, Sakhel, & de Groot, 2001). In this study, we focused on attraction to ingroup and interdependency.…”
