Winner of th 2023 American Board and Academy of Psychoanalytic and Psychodynamic Psychology (ABAPPP) Annual Award!This book aims to integrate different psychoanalytic schools and relevant research findings into an integrated psychoanalytic theory of the mind.A main claim explored here, is that a revised and expanded ego psychology constitutes the strongest foundation not only for a unified psychoanalytic theory, but also for the integration of relevant research findings from other disciplines. Sophisticated yet accessible, the book includes a description of the basic tenets of ego psychology and necessary correctives and revisions. It also discusses research and theory on interpersonal understanding, capacity for inhibition, defense, delay of gratification, autonomous ego aims and motives, affect regulation, the nature of psychopathology; and the implications of a revised and expanded ego psychology for approaches to treatment.The book will appeal to readers who are interested in psychoanalysis, the nature of the mind, the nature of psychopathology, and the implications of theoretical formulations and research findings for approaches to treatment. As such, it will also be of great value on graduate and training courses for psychoanalysis.
