Trait Approach Motivation Relates to Dissonance Reduction

Over 50 years of work on cognitive dissonance theory has suggested that dissonance reduction is a motivated process. However, no research has unambiguously demonstrated the direction of this motivation—whether it is approach or avoidance oriented. The action-based model of dissonance proposes that dissonance reduction is an approach-related process that assists in the implementation of decisions. It follows from the action-based model that approach-related personality traits should be related to greater dissonance reduction. The current research tested this idea. Study 1 found that trait behavioral approach sensitivity (BAS) related to more spreading of alternatives (more liking for the chosen over the rejected decision alternative) following a difficult decision. Study 2 found that BAS related to attitudes being more consistent with recent induced compliance behavior. This research therefore suggests that dissonance reduction is an approach-motivated process.
