Psychiatric Studies gathers writings on descriptive and experimental psychiatry that Jung published between 1902 and 1905, early in his career as a psychiatrist. The book opens with a study that foreshadows much of his later work and is indispensable to all serious students of his psychiatric career. This is his medical-degree dissertation, "On the Psychology and Pathology of So-called Occult Phenomena," a detailed analysis of the case of an adolescent girl who professed to be a medium. This volume also includes papers on cryptomnesia, hysterical parapraxes in reading, manic mood disorder, simulated insanity, and other subjects.
