Does extended mimicry result then in a loss of self-identity (or maybe lowered self-esteem)?

Does mimicry result in loss of self-identity? Research suggests that social exclusion increases mimicry, perhaps as a means to illicit integration back into the group. Does extended mimicry result then in a loss of self-identity (or maybe lowered self-esteem)? Possibly also question if inclusion gained from mimicry post-exclusion will result in lowered tendencies to mimic subsequent  behaviors. The actual research question is pretty open-ended, but should relate to the course (Social Psychology of the Unconscious), and generally Social Psychology.

Proposal should include:
– Introduction (~2 pages), should be able to answer how I arrived at the research question, the current state of existing research on this question, and the importance of answering this question.
– Methodology (~1 page), clear and concise methods, existing paradigms should be either referenced or used.
– Prediction of results (~1.5 pages), link to predictions of theories, and display consistency of results with predictions, no requirement to include actual statistics
– Discussion (~1.5 pages), including theoretical and practical implications of the predicted results.

Attached are 2 papers as a basis for mimicry as an affirmative response to social exclusion (Lakin & Chartrand, 2013), and costs of mimicry for the mimickee (Kot & Kulesza, 2016).
