What is the culture pattern approach to personality?

The culture pattern approach proposes that individual psychology is shaped by cultural practices rather than determining them; culture itself is an organized system of beliefs, rituals, and institutions that molds individuals to fit its values. People whose personalities do not align with their culture’s norms may be rejected, labeled as deviant, or even punished.

Those whose temperaments do not conform may be labeled as sinners, criminals, dissidents, or mentally ill. This perspective highlights a one-way influence — culture shaping personality rather than the reverse.

What is the interactionist approach to culture and personality?
