Personality develops through the process of socialization and is influenced by biological, environmental, cultural, and social factors. It is shaped from childhood through interactions with family, peers, school, work, religion, and media. Socialization involves learning social norms and developing a self-concept through roles and role performance within social groups. The family is the primary socializing agent, though socialization is a lifelong process as individuals take on new roles and statuses over their lifespan.
