Answer:
The answer is symbolic interactionism.
Explanation:
In sociology, the symbolic interactionist perspective states that society creates meaning through a series of "symbols". For example, a person might watch the news and create a symbolic image of another country, even if the person hasn't actually visited the place.
This theory explains that the shared meanings in a society shape individual behavior. In this passage, the mother is concerned because she believes groupthink will afect her son's perception of what is socially acceptable.
