Final answer:
Mead's theory elucidates how a child develops a sense of self, starting from simple imitation, moving through role-play, and culminating in the understanding of society's generalized other.
Step-by-step explanation:
George Herbert Mead's theory of social development is centered on how individuals develop a sense of self through social interactions. According to Mead, the process of self-development unfolds through various stages. In the preparatory stage, children engage in imitation without the ability to see from others' perspectives. The subsequent play stage sees children beginning to adopt the roles of others, understanding their perspectives by engaging in role-play, which is foundational for socialization. Eventually, children comprehend the idea of the generalized other, which is the set of societal norms and expectations they use to evaluate themselves and others, culminating in a developed 'self'.
