Models of Identity Development explore how individuals form their sense of self over time. One well-known model is Erik Erikson's psychosocial development theory, which outlines eight stages, each characterized by a specific conflict that must be resolved for healthy identity formation. This model emphasizes the role of social relationships and experiences in shaping identity throughout life. Another influential model is James Marcia's identity status theory, which categorizes identity development into four statuses: identity diffusion, identity foreclosure, identity moratorium, and identity achievement. These statuses reflect the degree of exploration and commitment individuals experience as they navigate their identities, highlighting the dynamic nature of identity formation during adolescence and beyond.
