“…For example, gender (Verkuyten, Masson, & Elffers, 1995;Yee & Brown, 1988), ethnicity (Davey & Norburn, 1980;Verkuyten et al, 1995) and age (Yee & Brown, 1988) all appear to be important in children's social categorization. Children, like adults, have also been found to distinguish others on the basis of body-type (Powlishta, Serbin, Doyle, & White, 1994), whether or not they are able-bodied (Maras, 1993), and with respect to personal attributes (Bennett, Dewberry, & Yeeles, 1991). This research has typically relied on methods which involve presenting children with stimuli, such as photographs representing members of different social categories, and requiring that they sort them into what they take to be homogeneous groupings.…”
