Confusion about confusion: Édouard Toulouse’s dementia test, 1905–20 (2019)

unapi

Psychiatrist Édouard Toulouse (1865–1947) is known today for his 1896 psychometric study of the novelist Émile Zola, and his contributions to mental hygiene, sexology, eugenics, and labour efficiency in inter-war France. This paper examines research undertaken in Toulouse’s Laboratory of Experimental Psychology at the Villejuif asylum near Paris. In 1905, Toulouse created a test that could differentiate between dementia and mental confusion, a test that could aid in the classification of patients at the overcrowded Villejuif facility. By 1920, however, the test’s early promise was undercut by unforeseen, ‘machinic’ resistance that emerged in the experimental process. This case study demonstrates the non-linear nature of scientific practice and limits of even the most innovative asylum reforms in this period.
