Final answer:
Charles Horton Cooley introduced the concept of 'the looking glass self,' which explains the development of an individual's identity through the perception of how others view them. George Herbert Mead expanded upon Cooley's work, emphasizing the role of social interaction in forming the self, introducing notions such as 'significant others' and 'generalized others.'
Step-by-step explanation:
The concept that Charles Horton Cooley termed to describe how an individual's self and identity are developed through social interaction is known as the looking glass self. This idea posits that we form our self-image through the way we believe others perceive us. George Herbert Mead further expanded on the notion by focusing on the development of the self through social interaction. Mead introduced the concept of significant others and generalized others to help explain how we internalize the views of society and particular individuals during the process of self-development. The self is not a static entity, but rather a dynamic structure continuously shaped and reshaped through social relations and interactions.
