APA Dictionary of Psychology

a variation of cognitive dissonance theory in which cognitive dissonance is considered particularly likely to occur when an inconsistency involves some aspect of the self. This perspective differs from self-affirmation theory in that dissonance can be reduced only by resolving the specific inconsistency that gave rise to the discomfort; it does not allow for the possibility that dissonance can be reduced by affirming some other aspect of the self. [originally proposed by U.S. psychologist Elliot Aronson (1932–  )]
