Self-concept is our total image of us, i.e. it is our total picture of our abilities and traits.
It is basically a cognitive construct that determines how we feel about ourselves and guides our actions.
According to Symonds, self-concept is the way an individual reacts to himself.
There are four aspects of self-concept, viz. How does a person perceive himself? What does he think about himself? How he values himself? and How he enhances or defends himself?
Our self-concept develops rapidly during early childhood and adolescence. It continues to form and change throughout our life span as we change.
