Ch06: Psychodynamic Theory — Freud & Defense Mechanisms(精神动力学理论)

Preparatory Mindset

Freud's psychodynamic theory underpins the psychodynamic therapy approach. The exam tests: three levels of consciousness (unconscious, preconscious, conscious), three-part personality structure (id, ego, superego), psychosexual stages, defense mechanisms, and the techniques of psychodynamic therapy (free association, dream analysis, interpretation, resistance, transference). The Week 16 questions confirm these are heavily tested.

Exam mindset: know the basic defense mechanisms (repression, projection, denial, transference, rationalization, isolation, displacement, sublimation, intellectualization, reaction formation, regression) — pairing each with an example. Freudian slip = parapraxis.

Topic Summary

Freud's psychodynamic theory describes the mind in three levels of consciousness (unconscious, preconscious, conscious) and three personality structures — id (pleasure principle, primary process), ego (reality principle, mediates drives and reality), and superego (moral conscience, internalized standards). Personality develops through psychosexual stages (oral, anal, phallic, latency, genital), with fixation leading to adult character patterns. Defense mechanisms (10 core: repression, projection, denial, displacement, sublimation, reaction formation, rationalization, intellectualization, isolation, regression) protect the ego from anxiety. Psychodynamic therapy techniques include free association, dream analysis (manifest vs. latent content), interpretation, resistance, transference (patient → therapist), and countertransference (therapist's response). The Oedipus/Electra complex drives superego formation in the phallic stage. Modern psychodynamic approaches (object relations, self psychology, attachment) emphasize early relationships and the therapeutic alliance, with brief psychodynamic therapy now evidence-based for common disorders.
