Self-esteem and clarity of the self-concept.

This article examines the association between evaluative and knowledge components of the self. Four studies tested the hypothesis that the self-concepts of low-self-esteem (LSE) people are characterized by less clarity or certainty than those of high-self-esteem (HSE) people. LSE Ss exhibited less extremity and self-reported confidence when rating themselves on bipolar trait adjectives (Study 1), less temporal stability in their trait ratings over a 2-month interval (Study 2), less congruence between their self-concepts and their subsequent perceptions of situation-specific behavior and memory for prior behavior (Study 3), and less internal consistency, lower self-rated confidence, and longer reaction times when making me/not me responses to pairs of opposite traits (Study 4). Alternative accounts of the results and the implications of self-concept clarity for understanding the pervasive impact of self-esteem on behavior are discussed.
