Rentsch and Heffner conducted research on the dimensions of selfconcept.
When they asked 20 questions to 200 university students, they found eight categories by which the participants defined themselves.
Some of the categories were concerned with personal attributes, such as interpersonal characteristics (e.g. I am a student), interest (e.g. I like dancing), personal beliefs (e.g. I am against child abuse), and self-awareness (e.g. I don’t get angry without a valid reason).
Others referred to the social environments such as ascribed characteristics (e.g. I am a citizen of India) or social differentiation (e.g. I am from another country).
Although our answers to specific questions related to self-concept can be different, the overall organization of self-concept is common for all.
