Final answer:
The degree of disparity between one's self-concept and one's actual experience is termed incongruence. Achieving congruence leads to a greater sense of self-worth and a healthy, productive life.
Step-by-step explanation:
The degree of disparity between one's self-concept and one's actual experience is termed incongruence. This concept was introduced by Carl Rogers, a humanistic psychologist. Incongruence occurs when there is a great discrepancy between our real self and ideal self. Achieving congruence, where our thoughts about our real self and ideal self are very similar, leads to a greater sense of self-worth and a healthy, productive life.
