Pierre Janet’s L'Automatisme psychologique, originally published in 1889, is one of the earliest and most important books written on the study of trauma and dissociation. Here it is made available, in two volumes, in English for the first time, with a new preface by Giuseppe Craparo and Onno van der Hart. Catalepsy, Memory, and Suggestion in Psychological Automatism, the first volume, examines three aspects of trauma and dissociation. Janet first explores catalepsy and analogous states, including comparing catalepsy to somnambulism, then discusses somnambulism, memory, and forgetting. Finally, Janet considers suggestion, amnesia, and distraction, as well as considering characteristics of suggestible individuals. Janet’s work is an unsurpassed experimental study of human actions in their simplest and most rudimentary forms, and a fundamental contribution to our understanding of trauma-related dissociation. This seminal work will be of great interest to researchers and students of psychoanalysis, philosophy, and modernism, as well as psychotherapists and psychoanalysts working with clients who have experienced trauma. It is accompanied by Subconscious Acts, Anesthesias, and Psychological Disaggregation in Psychological Automatism: Partial Automatism.

Pierre Janet’s L'Automatisme Psychologique, originally published in 1889, is one of the earliest and most important books written on the study of trauma and dissociation. Here it is made available, in two volumes, in English for the first time, with a new preface by Giuseppe Craparo and Onno van der Hart. The second volume, Subconscious Acts, Anesthesias, and Psychological Disaggregation in Psychological Automatism, covers four main topics. Beginning with an examination of subconscious acts, Janet first assesses partial catalepsies, subconscious acts, and posthypnotic suggestions, then proceeds to a consideration of anesthesias and simultaneous psychological existences. This is followed by discussion of several forms of psychological disaggregation, including spiritism, impulsive madness, hallucinations, and possessions. Finally, Janet considers elements of mental weakness and strength, from misery to judgement and will. Janet’s work, with its many descriptions of dissociative actions and the dissociative personality, will help clinicians and researchers to develop insight in trauma-related dissociation, and to become more adapt at relating to their patients’ dissociative actions. This seminal work will be of great interest to researchers and students of psychoanalysis, philosophy, and modernism, as well as psychotherapists and psychoanalysts working with clients who have experienced trauma. It is accompanied by Catalepsy, Memory, and Suggestion in Psychological Automatism: Total Automatism.

This second edition of the award-winning original text brings together in one volume the current thinking and conceptualizations on dissociation and the dissociative disorders. Comprised of ten parts, starting with historical and conceptual issues, and ending with considerations for the present and future, internationally renowned authors in the trauma and dissociation fields explore different facets of dissociation in pathological and non-clinical guises. This book is designed to be the most comprehensive reference book in the dissociation field and aims to provide a scholarly foundation for understanding dissociation, dissociative disorders, current issues and perspectives within the field, theoretical formulations, and empirical findings. Chapters have been thoroughly updated to include recent developments in the field, including: the complex nature of conceptualization, etiology, and neurobiology; the various manifestations of dissociation in clinical and non-clinical forms; and different perspectives on how dissociation should be understood. This book is essential for clinicians, researchers, theoreticians, students of clinical psychology psychiatry, and psychotherapy, and those with an interest or curiosity in dissociation in the various ways it can be conceived and studied.

The Marquis de Puységur, Artificial Somnambulism, and the Discovery of the Unconscious Mind presents the first full English translation of a foundational text in the history of psychodynamic thinking, and provides a contextual explanation of its contemporary significance. Written by Puységur in 1784, Memoirs to Serve the History and Establishment of Animal Magnetism describes the author’s exploration and discovery of “artificial somnambulism,” a state that reveals insights into the subconscious mind. Building on the healing techniques of Franz Anton Mesmer, Puységur kept detailed notes on his practice with patients, including their names, symptoms, and follow-up information, providing a unique insight into his process. The full text of this original publication is presented here, complemented by a historical introduction and editor’s notes. The Marquis de Puységur, Artificial Somnambulism, and the Discovery of the Unconscious Mind will be of great interest to academics and scholars of psychoanalysis, psychotherapy, and the history of psychology, hypnosis, and mental health. It will also appeal to practicing clinicians.
