“…Previous research has demonstrated that when the intergroup comparative context is salient perceivers self-categorize by self-stereotyping (Hogg & Turner, 1987;Simon, Glassenbayer, & Stratenwerth, 1991;Simon & Hamilton, 1994;Simon, Pantaleo, & Mummendey, 1995;Spears, Doosje, & Ellemers, 1997) assigning the same traits to the self and the ingroup (Cadinu & Rothbart, 1996;Study 1;Clement & Krueger, 2000Gramzow, Gaertner, & Sedikides, 2001;Krueger & Zeiger, 1993;Mullen, Dovidio, Johnson, & Copper, 1992;Otten, 2002, Smith, & Henry, 1996; and will tend to perceive both the ingroup and the outgroup to be more homogenous (Ellemers & van Knippenberg, 1997;Haslam, Oakes, Turner, & McGarty, 1995). Self-stereotyping is an expression of differentiation from outgroups, therefore it seems reasonable to draw a parallel here with research on behavioral contrast to outgroups.…”
