Step-by-step explanation:
Self-concept, as explained by the middle-range theory, states that it is our thoughts and feelings about ourselves. According to Carl Rogers, our self-concept is divided into two categories: the ideal self and the real self. The ideal self is the person we would like to be, while the real self is the person we actually are. Rogers emphasized the importance of achieving congruence between these two selves, which leads to a greater sense of self-worth and a healthy, productive life. Parents can facilitate their children's positive self-concept development by providing them with unconditional positive regard.
