Final answer:
Mead's spontaneous aspect of the self is known as the 'I', which operates alongside the 'me', or the organized attitudes of others. The 'I' is part of Mead's theory that the self develops through social interactions and stages, essential for individuals to take the perspective of others and form their identity.
Step-by-step explanation:
Mead's spontaneous, unsocialized, unpredictable, and impulsive aspect of the self, referred to in the question, is known as the 'I'. In George Herbert Mead's theory, the 'I' represents the part of the self that is the spontaneous and less socialized response to the 'me', which consists of the organized set of attitudes of others that the individual assumes. Mead's conceptualization of the 'I' and 'me' forms the basis of his understanding of the self, which develops through social interaction and is comprised of both the predictable patterns of social behavior and the spontaneous, unpredictable individual reactions.
Mead believed in the development of self through stages, such as the preparatory, play, and game stages, where individuals learn to take the perspective of the 'other'—a crucial element in the formation of the self. Interestingly, he observed that without social interaction, people like Danielle would struggle to develop a 'self' because they are unable to see themselves from someone else's viewpoint, displaying the importance of social experiences in the shaping of one's identity.
