Identity and Self constitutes a central sociological and social psychological domain focusing on how individuals develop, perceive, and express their unique sense of who they are, and how this understanding is shaped by social interactions and broader societal influences. This area examines the self as a social construct, exploring the processes through which individuals become self-aware and form their personal identity (self-identity), encompassing their conscious perceptions, thoughts, feelings, and beliefs about themselves. Key concepts include George Herbert Mead's theory of the social self, which differentiates between the "I" (the spontaneous, acting self) and the "me" (the socialised self, reflecting internalised societal perspectives, including those of significant others and the generalised other). This domain also delves into various facets of identity, such as gender identity, sexual orientation, personality, and the impact of social roles, experiences, and social groups (in-groups, out-groups) on self-concept. It explores how individuals manage their self-presentation through impression management and face-work in social interactions.
