The self-discrepancy theory states that people compare themselves to internalized standards called "self-guides". These different representations of the self can be contradictory and result in emotional discomfort. Self-discrepancy is the gap between two of these self-representations. The theory states that people are motivated to reduce the gap in order to remove disparity in self-guides.〔Orellana-Damacela, L.E., Tindale, T.S., & Suarez-Balcazar, Y. (2000). Decisional and behavioral procrastination: How they relate to self-discrepancies. Journal of Social Behavior and Personality, 15, 225–238.〕 Developed by Edward Tory Higgins in 1987, the theory provides a platform for understanding how different types of discrepancies between representations of the self are related to different kinds of emotional vulnerabilities. It maintains close ties to a long-standing tradition of belief-incongruity research. Higgins sought to illustrate that internal disagreement causes emotional and psychological turmoil. Before, many theories such as the self-inconsistency theory,〔Lecky, P. (1961). Self-consistency: A theory of personality. New York, NY Shoe String Press〕 the cognitive dissonance theory,〔Festinger, L. (1957) A theory of cognitive dissonance, Stanford, CA: Stanford University Press〕 and the imbalance theory (e.g., Heider, 1958), had done just that; however, Higgins aspired to predict and define what distinct emotions the cognitive imbalances would result in. Previous self-imbalance theories had recognized only positive or negative emotions, in a general sense, associated with the belief inconsistency. The self-discrepancy theory was the first to improve on these generalizations and assign specific emotions and affects to the disparity. It asserts two cognitive dimensions from which various self-states are measured: domains of the self and standpoints of the self.〔Higgins, E. T. (1987). Self-discrepancy; A theory relating self and affect, Psychological Review, 94, 319-340.〕 The theory proposes how a variety of self-discrepancies represents a variety of types of negative psychological situations that are associated with different kinds of discomfort (p. 319).〔 A primary goal of the Self-Discrepancy Theory is to help aid in predicting which types of incongruent ideas will cause such individuals to feel different kinds of negative emotions (p. 319).〔 The structure of the theory was built based on three ideas: to distinguish among the different kinds of discomfort felt by those people holding incongruent ideals experienced, to relate the different possible kinds of emotional vulnerabilities felt by the different types of discrepancies that people may have for the self, and to consider the role of both the availability and accessibility to the different discrepancies that may potentially have in influencing the kind and type of discomfort they are most likely to experience. Also, the theory suggests that individuals are motivated to reach a goal of where the self-concept matches the appropriate self-guides (p. 321).〔 ==Domains of the self== The theory postulates three basic domains of the self: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-discrepancy theory」の詳細全文を読む スポンサード リンク
