When do self-discrepancies have specific relations to emotions? The second-generation question of Tangney, Niedenthal, Covert, and Barlow (1998)

Self-discrepancy theory (E. T. Higgins, 1987) hypothesizes that actual-idea l discrepancies are uniquely related to dejection emotions, whereas actual- ought discrepancies are uniquely related to agitation emotions. A review of the literature testing this hypothesis supports an affirmative answer to t he question "Is there an effect?" However, as the results of J. P. Tangney, P. M. Niedenthal, M. V. Covert, and D. H. Barlow's (1998) study indicate, the predicted unique relations are not always found. Their article contribu tes to the development of self-discrepancy theory by shifting attention to the second-generation question "When is there an effect?" Four variables th at moderate the likelihood of finding unique discrepancy-emotion relations are discussed in the present article: the magnitude of a self-discrepancy, the accessibility of a self-discrepancy, the applicability and relevance of a self-discrepancy in a current context, and the importance of a self-disc repancy to the person.
