Self-system (also referred to as self-dynamism) was a personality concept created by Harry S. Sullivan that he believed served to minimize the tension of anxiety. The self-system was defined as a unique collection of experiences that was used to describe one's own self. For the most part, Sullivan claimed that the self-system was the result of appraisals provided by caregivers during early childhood.〔Ewen, Robert B. (2010).“Harry Stack Sullivan: The Interpersonal Theory of Psychiatry.” In ''An Introduction to Theories of Personality. Psychology Press''. 7th Edition. pp. 141-145. ISBN 978-1-84169-746-8〕 Sullivan considered the self-system as a major structure in personality development that could appear as early as 6 months of age. The positive reinforcement a child received during mid-infancy would not only prompt the development of the self-system, but also act as preparation for societal expectations. == Sullivan's self-system == In order for the self-system to develop, Sullivan affirmed that "good me" and "bad me" personifications must first form. These personifications are organized perceptions that are account of certain experiences. The "good me" personification consists of experiences that are rewarded, which a child would sense a noticeable decrease of anxiety. The "bad me" personification on the other hand consists of experiences that are punished and cause greater anxiety to a child. These personifications then fuse into what Sullivan called the self-system. Furthermore, Sullivan emphasized that the self-system was the product of two additional factors: # The exploration of an infant's own body: Sullivan provided thumb sucking as an example of the exploration a child has during mid-infancy. The very act of thumb sucking would help differentiate the infant from himself or herself and others. # The appraisals from caregivers: Sullivan believed that interpersonal relationships were vital in personality development and specifically in the formation of the self-system. Therefore the type of appraisals a child receives will determine the kind of self-dynamism they will develop. 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 system」の詳細全文を読む スポンサード リンク
