Final answer:
Personality change, according to psychoanalytic theory, stems from alterations in the unconscious mind, which stores repressed memories and desires.
Step-by-step explanation:
Based on psychoanalytic theory, personality change is possible through changes in the unconscious mind. Psychoanalytic theory, pioneered by Sigmund Freud, suggests that our personality develops from a conflict between our biological drives and our internalized social controls. The unconscious mind, a central concept of this theory, contains repressed memories and desires that shape our behaviors and personality traits. Freud's approach emphasized the importance of resolving conflicts within the unconscious, typically originating from early childhood experiences, through therapeutic methods such as dream analysis and free association. Therefore, the correct answer to how personality change is possible according to psychoanalytic theory is B) Through changes in the unconscious mind.
