symbolic interactionism

Explanation:

Symbolic interactionism is a school of thought in sociology that explains social behavior in terms of how people interact with each other via symbols; in this view, social structures are best understood in terms of such individual interactions. Symbolic interactionism was developed by thinkers such George Herbert Mead and Herbert Blumer in the 20th century. Mead believed that one's self develops through social interactions. Moreover, how people communicate and interact with each other depends on how they interpret factors such as language, actions, and statuses (potential symbols). For example, one might interpret a handshake as either a friendly greeting or cool farewell, depending on context (the symbolism of a handshake varies). Sometimes symbols change; long hair in males once symbolized rebellion, but now does not.
