Association of need for cognition with judgments of height, weight, and body fat covariation.
559 college students, assessed for Need for Cognition, judged whether height, weight, and body fat were correlated using judgment probes that controlled for framing and conditional format. A principal components analysis of Need for Cognition scores identified two factors underlying the scale, which may be important in judgment outcome. In addition, judgments about correlations among height, weight, and body fat were similar to those of previous studies. Furthermore, the hypothesis that Need for Cognition would be related to the tendency to judge a negative correlation between height and body fat, i.e., a possible illusory correlation, was confirmed. Results are discussed relative to the Elaboration Likelihood Model of Persuasion.
