Final answer:
The central feature of personality suggested by Carl Rogers is the self-concept, which includes our thoughts about our real self and ideal self, with congruence playing a key role in overall well-being.
Step-by-step explanation:
Carl Rogers suggested that the self-concept is a central feature of personality. According to Rogers, self-concept encompasses our thoughts and feelings about ourselves. It is defined by two categories: the ideal self, which is the person you wish to be, and the real self, which is the person you actually are. Rogers posited that a high level of congruence, or similarity, between the ideal self and the real self leads to a greater sense of self-worth and a more productive life. Moreover, the concept of congruence refers to a state of being where our thoughts about our real and ideal selves are very similar, reflecting an accurate self-concept. Parents contribute to this by providing unconditional positive regard, which fosters a supportive environment for developing a healthy self-concept.
