Final answer:
Carl Rogers emphasized achieving congruence between the real and the ideal self through honest self-acceptance to maximize self-actualization and achieve a greater sense of self-worth.
Step-by-step explanation:
Carl Rogers, a humanistic psychologist, believed that for individuals to reach their full potential and maximize their self-actualization, they need to accept information about themselves as honestly as possible. According to Rogers, achieving congruence between our real self and our ideal self is key to self-worth and a productive life. This is done through a process of self-examination and personal growth, where an honest acceptance of who we are leads to high congruence and thereby a greater sense of self-worth. This contrasts with his notion of incongruence, where a discrepancy between the ideal and the real self can cause maladjustment. Therefore, improving congruence through unconditional positive regard and self-determination results in healthier psychological development.
