Identity formation is the process by which individuals develop a sense of self and understanding of who they are. It involves the exploration and integration of various aspects of one's personality, values, beliefs, and experiences to create a cohesive sense of identity. This process typically occurs during adolescence and young adulthood, but can continue throughout the lifespan. Identity formation is influenced by a variety of factors, including social interactions, cultural norms, personal experiences, and self-reflection. Researchers in this area seek to understand how individuals develop a sense of identity, how it influences their behavior and decision-making, and how it can change over time.
