The influence of mood on the search for supporting versus conflicting information: dissonance reduction as a means of mood regulation?

Focusing on similarities between the mood regulation approach and dissonance theory, this article addresses the interplay between dissonance and mood by examining how individuals search for information after making a decision while under the influence of positive versus negative mood. Study 1 suggested that negative mood increased the preference for consonant over dissonant information after decisions, whereas positive mood led to a more balanced information search. In Study 2, participants in negative mood rated consonant information as more pleasant and dissonant information as more annoying than participants in positive mood. In addition, the results suggested that mood regulation processes took place. In Study 3, the findings from Study 1 were replicated with a paradigm in which higher stakes were involved.
