【明報專訊】The theory of "Self-concept", proposed by American psychologist Carl Rogers, is about one's perception of themselves, which includes their evaluation of their manners when dealing with people, their abilities and their values. According to Rogers, our self-concept is established during our puberty. A self-concept is made up of the "ideal self" (the person he or she wants to be) and the "actual self" (his or her image of himself or herself at the moment). A person has a better self-concept when his or her ideal self and actual self match, and a poorer self-concept when there is a great discrepancy between them. Those with a better self-concept have a higher chance of self-actualisation.
