Abstract
Two studies were conducted to test a model of the distinctiveness-based ill usory correlation (IC) phenomenon that suggests there are two components op erating with ICs: cognitive memorial, and affective. In Expt 1 (N = 118), t wo stimulus arrays were developed that were equivalent in regards to valenc e (good or bad extremity) but differed in regards to the affect dimension ( high or low emotional intensity). Consistent with predictions drawn from th e proposed model, the magnitude of the IC effect was higher in the high emo tional intensity than in the low emotional intensity condition, but only si gnificantly so on the measures (estimation and general evaluation) that hav e been hypothesized to be most sensitive to the affective component. In Exp t 2 (N = 52), the affective qualities were matched and the valence properti es varied in two stimulus arrays. As predicted, the IC effect differed sign ificantly between conditions only on the measure (assignment) thought to be most sensitive to the memorial component. The results are discussed in ter ms of the implications of the findings for the proposed mechanisms of illus ory correlation.
