Final answer:
The term for a person's self-concept based on identification with social groups is social identity. This concept is integral to understanding personal and cultural identity elements.
Step-by-step explanation:
The part of a person's self-concept based on their affiliation with certain social groups in society is referred to as social identity. This concept is vital in understanding how individuals define themselves concerning various groups, whether that's by ethnicity, culture, or shared interests. For instance, someone may identify with being a part of a religious group, an ethnic community, or a professional organization. Social identity ties deeply into one's cultural identity as well, shaped by factors like family upbringing, language, and geographical location. It's these components and affiliations that collectively forge our sense of who we are, which encompasses our personal identity and group identity.
For example, someone may identify themselves as a member of a certain religion or political party, and this identification with the group shapes their self-concept and influences their behavior and attitudes. Social identity can be important for individuals in terms of providing a sense of belonging, validation, and support from others who share similar values, beliefs, or experiences.
