in psychology, the correspondence of inner experiences and the expression of emotions, that is, the ability of the personality to act sincerely, openly expressing one’s feelings. The concept was introduced and popularized by the American psychologist Carl Rogers — one of the creators of humanistic psychology. Rogers believed that when a person returns to themself the suppressed and denied parts of one’s Self, restoration of mental health occurs. To be congruent, that is, to be oneself, and not such as a person would like to seem, — is a sign of psychological health.
