Final answer:
Adult thinking progresses through stages of conformity, autonomy, and individuality, with each stage representing a deeper level of self-concept and personal growth within the context of social roles and expectations.
Step-by-step explanation:
Adult thinking and the development of self-concept progress through stages of conformity, autonomy, and individuality. During adolescence, as described by Erikson's theory of psychosocial development, individuals focus on defining their personal identity, which involves exploring different roles and sometimes adopting values aligned or in conflict with parental expectations. In early adulthood, after forming a secure sense of self, adults are ready to build intimate relationships, extending beyond achieving independence to forming connections with others while expressing their individuality.
As adults mature, they often transition from seeking acceptance and complying with group norms—conformity—to asserting their independence, or autonomy. With further maturation and experiences, adults can reach a level of individuality, where they maintain their personal beliefs and values even when they differ from societal expectations or group norms. This progression embodies the socialization process and the complex changes in social roles and expectations throughout the life span.
