Among those who have broken off from Freud, after having been associated with him, are Stekel, Jung, and Adler. Stekel has published ten volumes of case histories which are valuable for the beginner who needs to acquire a sense of what sort of thing the human mind is capable. The other two are of more theoretical importance. Jung’s _Psychological Types_ is of the most immediate interest to social scientists, although his speculations about the “racial unconscious” are suggestive. Alfred Adler’s standpoint is set out in his _Individual Psychology_. His circle in Vienna publishes a journal. An excellent manual is _The Structure and Meaning of Psychoanalysis_ (New York, 1930), by William Healy, Augusta F. Bronner, and Anna Mae Bowers. The psychoanalytical movement can be placed in the general perspective of medical psychology by referring to such a manual as William A. White’s _Outlines of Psychiatry_ or Bernard Hart’s _Psychopathology_. There are excellent books in German on medical psychology by Kronfeld, Birnbaum, Schilder, Kretschmer, and many others. The general movements in the field can be followed in the _American Journal of Psychiatry_ or the _Journal of Nervous and Mental Diseases_, the latter of which is edited by William A. White and Smith Ely Jelliffe, who also supervise the well-known series of books, usually translations, called the “Nervous and Mental Disease Monograph Series.” Pierre Janet’s _Psychological Healing_ reviews the general history of psychopathology. Among the innumerable articles and books which undertake to appraise the clinical and normal implications of psychoanalysis, the symposium edited by Hans Prinzhorn may be chosen, _Krisis der Psychoanalyse_ (Leipzig, 1928), Band I (the projected second volume will not appear). Otto Rank, who has likewise broken with Freud, is publishing a series of books on the psychoanalytical interview which promises to serve as a bridge between the general theory and the objective studies of the interview situation which are in progress in America. On the special problem of personality and character types, the volume by A. A. Roback, _The Psychology of Character_, may be instanced as a very comprehensive guide to the literature. His _A Bibliography on Personality_ is also available. An acute analysis of typologies was offered by O. Selz before the German experimental psychologists in 1923. See the following: Selz, O. “Über die Personlichkeitstypen und die Methoden ihrer Bestimmung,” _Bericht über den VIII. Kongress für experimentelle Psychologie_. Jena, 1924. Klüver, H. “An Analysis of Recent Work on the Problem of Psychological Types,” _Journal of Nervous and Mental Diseases_, LXII, No. 6 (December, 1925).
