Wynn Schwartz, Ph. D., is a clinical and experimental psychologist and research psychoanalyst. He is a professor of psychology at the Massachusetts School of Professional Psychology and on the faculty of Harvard Medical School and the Harvard Extension School. He has been a professor at Wellesley College and has taught at the Boston Psychoanalytic Society and Institute and the Massachusetts Institute of Psychoanalysis. He maintains a psychotherapy practice in Boston. Dr. Schwartz has been interested in clarifying fundamental aspects of the subject matters of psychotherapy, psychoanalysis, dreaming and hypnosis. His published work has been both conceptual and experimental. Some of his experimental studies have focused on dreaming and problem representation and dreaming and memory, and others on hypnosis and episodic memory. As a student of Descriptive Psychology, Dr. Schwartz has been especially concerned with theory-free, pre- empirical formulations of what he believes are central subject matters for psychology, such as the concepts of action and responsibility, the range of the possible phenomena that are covered by the term "hypnosis", the limits and nature of psychotherapy, and the concept of "person".
