WebGOAL-DERIVED CATEGORIES 149 1 Tversky (1977), in his contrast model of similarity, posited that the frame of reference or context of judgment can alter similarity judgments. Whereas Tversky emphasized the “local” context of the stimulus set itself, our re- search focused on how the perceiver’s salient goals can frame perceptions.
