Volume 11 begins with a timely assessment of self psychology and intersubjectivity theory, with original contributions by Carveth, Trop, and Powell, and a critical commentary by P. Ornstein. Clinical studies span the transferences, the complementarity of individual and group therapy, the termination phase, and multiple personality disorder. A special section of dying and mourning encompasses women professionals and suicide, the self psychology of the mourning process, and the selfobject function of religious experience with the dying patient. The volume concludes with theoretical and applied studies of personality testing in analysis, writer’s block, The Guilt of the Tragic Man, and the historical significance of self psychology. A testimony to the evolutionary growth of self-psychology, The Impact of New Ideas will be warmly welcomed by readers of the Progress in Self Psychology series.
