The expectancy-based illusory correlation (EB; Hamilton & Rose, 1980), the distinctiveness-based illusory correlation (DB; Hamilton & Gifford, 1976) and the intuitive analysis of covariance (lAC; Schaller & O'Brien, 1992) paradigms have been proposed as explanations of stereotype formation. Meanwhile, essentialism of the target groups (Yzerbyt, Judd, & Comeille, 2003), in-group membership (Schaller & Maass, 1989) and cognitive load of the stimulus materials (Mullen & Johnson, 1990) have been proposed to moderate this relationship. In addition, moderators unique to each paradigm (expectancy strength in the EB paradigm, Hamilton & Rose, 1980; attribute valence in the DB paradigm, Johnson, Mullen, Carlson, & Southwick, 2001; and constraint strength in lAC paradigm, Cordray & Shaw, 1978) have been proposed to moderate this relationship. Essentialism was operationalized as the naturalness or artificiality of the groups employed in the stimulu erials. In-group membership was operationalized as the assigimient of participants to one of the presented target groups. Cognitive complexity was operationalized as the number of stimulus sentences, the duration of the stimulus presentation and the verbal complexity of the stimulus sentences. Expectancy strength was operationalized as the judged strength of association between each attribute and the corresponding target group. Attribute valence was operationalized as the judged valence of the attributes used to describe the distinct/minority group in the stimulisis sentences Constraint salience was operationalized as the judged potential impact of the constraining variable on the outcome variable. For the first time, a meta-analytic integration of previous research on these three paradigms was conducted.
