define self-identity
Definition of Self-Identity. Self-identity, or self-concept, is one's concept of oneself, including the perceptions one has about one's abilities, flaws, status, and worth. Sociologists study how self-identity develops, especially in relation to social factors. One influential view of self-identity is that of George Herbert Mead, who argued that a person does not begin life with a self, but rather develops a self (and self-consciousness) by interacting with others.
