sexual identity. Adolescents become curious about the roles they will play in the adult world as they transition from childhood to adulthood. Initially, they are apt to experience some role confusion—mixed ideas and feelings about the specific ways in which they will fit into society—and may experiment with a variety of behaviors and activities (e.g. tinkering with cars, baby-sitting for neighbors, affiliating with certain political or religious groups). Eventually, Erikson proposed, most adolescents achieve a sense of identity regarding who they are and where their lives are headed. The teenager must achieve identity in occupation, gender roles, politics, and, in some cultures, religion. This is not always easy, however. The teenager must seek to find their place in this world and to find out how they can contribute to the world. Erikson is credited with coining the term "identity crisis". He describes identity crisis as a critical part of development in which an adolescent or youth develops a sense of self. Identity crisis involves the integration of the physical self, personality, potential roles and occupations. It is influenced by culture and historical trends. This stage is necessary for the successful development of future stages. Each stage that came before and that follows has its own 'crisis', but even more so now, for this marks the transition from childhood to adulthood. This passage is necessary because "Throughout infancy and childhood, a person forms many identifications. But the need for identity in youth is not met by these." This turning point in human development seems to be the reconciliation between 'the person one has come to be' and 'the person society expects one to become'. This emerging sense of self will be established by 'forging' past experiences with anticipations of the future. In relation to the eight life stages as a whole, the fifth stage corresponds to the crossroads: What is unique about the stage of Identity, is that it is a special sort of synthesis of earlier stages and a special sort of anticipation of later ones. Youth has a certain unique quality in a person's life; it is a bridge between childhood and adulthood. Youth is a time of radical change—the great body changes accompanying puberty, the ability of the mind to search one's own intentions and the intentions of others, the suddenly sharpened awareness of the roles society has offered for later life. Adolescents "are confronted by the need
