Explanation
Peer groups are social groups whose members share similar characteristics such as age, educational background, lifestyle, or social status. Peer groups play an important role in processes of socialization, identity formation, conformity, and social learning.
Especially during adolescence and early adulthood, peer groups often become highly influential because individuals increasingly orient themselves toward friends and social networks rather than exclusively toward family or formal institutions.
Peer groups may shape:
- norms and values,
- language and communication styles,
- consumer behavior and lifestyles,
- political attitudes,
- risk-taking behavior,
- and forms of deviance or conformity.
In criminology, peer groups are particularly important in learning theories of crime. Approaches such as Differential Association Theory and Social Learning Theory argue that criminal behavior may be learned, reinforced, and normalized within peer networks.
Peer groups may therefore function both as sources of social support and as environments in which deviant behavior is encouraged or rewarded.
Theoretical Reference
Peer groups are associated with socialization theory, learning theories of crime, symbolic interactionism, youth sociology, and subcultural theory.
