Socialization helps people learn to function successfully in their social worlds. How does the process of socialization occur? How do we learn to use the objects of our society’s material culture? How do we come to adopt the beliefs, values, and norms that represent its non-material culture? This learning takes place through interaction with various agents of socialization, like peer groups and families, plus both formal and informal social institutions.

Social groups often provide the first experiences of socialization. Families, and later peer groups, communicate expectations and reinforce norms. People first learn to use the tangible objects of material culture in these settings, as well as being introduced to the beliefs and values of society.

The social institutions of our culture also inform our socialization. Formal institutions—like schools, workplaces, and the government—teach people how to behave in and navigate these systems. Other institutions, like the media, contribute to socialization by inundating us with messages about norms and expectations.

Our direct interactions with social groups, like families and peers, teach us how others expect us to behave. Likewise, a society’s formal and informal institutions socialize its population. Schools, workplaces, and the media communicate and reinforce cultural norms and values.
