Primary use / Purpose:
Cacioppo and Petty created the Need for Cognition Scale in 1982. The original scale included 34 questions. Two years later, Cacioppo and Petty collaborated with Chuan Feng Kao to shorten the scale to the 18-item format. The 18-item Need for Cognition Scale has been used in several settings. Investigators have used the scale to examine (a) the relationship between students’ need for cognition and their academic performance (Sadowski & Gulgoz, 1992a, 1996; Tolentino, Curry, & Leak, 1990), (b) how one’s need for cognition and religious views impact satisfaction with one’s life (Gauthier, Christopher, Walter, Mourad, & Marek, 2006), (c) how jurors’ need for cognition influences their legal decisions (Bornstein, 2004), and (d) how college students’ need for cognition influences their self-reported satisfaction with their lives as a whole (Coutinho & Woolery, 2004).
Based on previous research, the Need for Cognition Scale appears to be a valid and reliable measure of individuals’ tendencies to pursue and enjoy the process of thinking—that is, of their "need for cognition" (Cacioppo & Petty, 1982; Cacioppo, Petty, Feinstein, & Jarvis, 1996; Cacioppo et al., 1984; Sadowski, 1993; Sadowski & Gulgoz, 1992b). Need for Cognition scores are not influenced by whether an individual is male or female, or by differences in the individual’s level of test-taking anxiety or cognitive style (the particular way that an individual accumulates and merges information during the thinking process). In general, scores on the Need for Cognition Scale also are not impacted by whether or not the individuals are trying to paint a favorable picture of themselves (Cacioppo & Petty, 1982).
