What it is

Published in French in 1889, L’Automatisme psychologique presents Pierre Janet’s clinical and experimental work on automatism and awareness. A two-volume English translation was published separately in 2021.

What it covers

Janet described total and partial automatisms and proposed ideas about psychological dissociation and subconscious activity. These are historical interpretations of observations, not established explanations of every dissociative symptom.

Historical cases and later influence

Janet discussed individual cases, including Marie, in which he used hypnosis and suggestion. Historical case reports do not by themselves establish that a recalled memory is accurate, identify a general cause of symptoms, or demonstrate treatment effectiveness.

Reading level and limits

This advanced historical work uses the clinical language and assumptions of its time. This entry draws on a library catalogue and selected later historical accounts; the complete book was not reviewed for this entry.

Paired academic and clinical scholarship

Paired work: Pierre Janet and the Breakdown of Adaptation in Psychological Trauma (Bessel A. van der Kolk and Onno van der Hart, 1989)

Reference: van der Kolk, B. A., & van der Hart, O. (1989). Pierre Janet and the breakdown of adaptation in psychological trauma. American Journal of Psychiatry, 146(12), 1530–1540.

A historical and clinical discussion of Janet’s ideas about trauma and dissociation. The paper interprets his work; it does not establish a universal mechanism or comparative superiority over other theories.

Source-mapped claims and evidence notes

Claim 1: Janet described automatism and proposed an account of psychological dissociation in clinical and experimental observations. (The library record identifies the 1889 work and makes a digitised copy available; the complete text was not reviewed for this entry.) [Source 1: Janet, P. (1889). L’automatisme psychologique: Essai de psychologie expérimentale sur les formes inférieures de l’activité humaine. Félix Alcan.]

Claim 2: In the case of Marie, Janet described using hypnosis and suggestion to alter an idea associated with a distressing experience. (A later historical discussion reports Janet’s account. A single case does not establish that a recovered memory is accurate or that a treatment is generally effective.) [Source 4: Orne, M. T., Whitehouse, W. G., Dinges, D. F., & Orne, E. C. (1988).
