Socialization is the lifelong process by which individuals learn the norms, values, and behaviors appropriate within their culture. It occurs through both formal and informal social agents like family, peers, and institutions. Primary socialization happens in early life as infants learn language and cognition from family. Secondary socialization continues through life as people are socialized by peers and formal institutions like schools. Anticipatory socialization prepares individuals for future roles, while re-socialization involves discarding old behaviors and adopting new ones during life transitions. Socialization ensures the continuity of culture across generations.
