the fifth of Erikson’s eight stages of psychosocial development, marked by an identity crisis that occurs during adolescence. During this stage, the individual may experience a psychosocial moratorium, a period of time that permits experimentation with social roles. The individual may “try on” different roles and identify with different groups before forming a cohesive, positive identity that allows him or her to contribute to society; alternatively, the individual may identify with outgroups to form a negative identity or may remain confused about his or her sense of identity, a state Erikson calls identity diffusion. See also identity status model.
