In psychology, the term identity crisis (coined by psychologist Erik Erikson) means the failure to achieve ego identity during adolescence.〔Kendra Cherry, (Identity Crisis - Theory and Research )〕〔(Schultz, 216)〕 The stage of psychosocial development in which identity crisis may occur is called the Identity Cohesion versus Role Confusion stage. During this stage (that is, adolescence), adolescents are faced with physical growth, sexual maturation, and integrating ideas of themselves and about what others think of them.〔(Schultz, 215-216)〕 Adolescents therefore form their self-image and endure the task of resolving the crisis of their basic ego identity. Successful resolution of the crisis depends on one’s progress through previous developmental stages, centering on issues such as trust, autonomy, and initiative.〔 ==Concept== (詳細はErikson's own interest in identity began in childhood. Born Ashkenazic Jewish, Erikson felt that he was an outsider. His later studies of cultural life among the Yurok of northern California and the Sioux of South Dakota helped formalize Erikson's ideas about identity development and identity crisis. Erikson described those going through an identity crisis as exhibiting confusion.〔 They often seem to have no idea who or what they are, where they belong or where they want to go. They may withdraw from normal life, not taking action or acting as they usually would at work, in their marriage or at school. They may even turn to negative activities, such as crime or drugs, as a way of dealing with identity crisis. To someone having an identity crisis, it is more acceptable to them to have a negative identity than none at all.〔 Erikson felt that peers have a strong impact on the development of ego identity during adolescence. He believed that association with negative groups such as cults or fanatics could actually "redistrict" the developing ego during this fragile time. The basic strength that Erikson found should develop during adolescence is fidelity, which only emerges from a cohesive ego identity. Fidelity is known to encompass sincerity, genuineness and a sense of duty in our relationships with other people.〔 Erikson described identity as "a subjective sense as well as an observable quality of personal sameness and continuity, paired with some belief in the sameness and continuity of some shared world image. As a quality of unself-conscious living, this can be gloriously obvious in a young person who has found himself as he has found his communality. In him we see emerge a unique unification of what is irreversibly given—that is, body type and temperament, giftedness and vulnerability, infantile models and acquired ideals—with the open choices provided in available roles, occupational possibilities, values offered, mentors met, friendships made, and first sexual encounters."〔(Erikson, 730)〕 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「identity crisis」の詳細全文を読む スポンサード リンク
