noun
1. : the analysis and classification of mental data (as sensations and feelings) especially by introspection — contrasted with experimental psychology
2. : a modification of psychoanalysis that adds to the concept of the personal unconscious by postulating a racial or collective unconscious, that objects to a narrowly sexual interpretation of libido, and that advocates that psychotherapy be conducted in terms of the patient's present-day conflicts and maladjustments rather than in terms of his early psychosexual development
