3 o8 PSYCHOLOGY 



Revault D'ALLONES (whose name is known to students 

 of general Psychology for his work on " Attention" and 

 "Les troubles de 1'intelligence"). At the clinic for mental 

 diseases at the Salpetriere are J. VOISIN, J. SEGLAS, whose 

 investigations relate chiefly to Hallucinations, and 

 P. CHASLIN. 



At the College de France is Pierre JANET (Experimental 

 Psychology), a giant among scientists, who of contem- 

 porary French psychologists is by far the best known to 

 American students. He first demonstrated subconscious 

 perception of sensory stimulations applied to anaesthetic 

 tactile and visual areas; and, more fully than any other 

 investigator, he has analyzed the various forms of amnesia. 

 In his " L ' Automatisme psychologique " (1889) and 

 various recent publications in the "Journal de Psych- 

 ologic normale et pathologique " and other periodicals, 

 he has, on experimental grounds, developed the theory 

 of hysteria in its numerous manifestations, such as 

 double personality, automatic writing, phobias, etc., as 

 phenomena of dissociated processes independent of per- 

 sonal consciousness. These processes he conceives as 

 expressions of residua of early experiences; systematized 

 or organized residua which do not directly affect con- 

 sciousness, but which are, nevertheless, intelligent, in 

 the sense that, in the conditions of experiment, they lead 

 to suitable adaptations of behavior. It is thus that the 

 scientific imagination of Janet and his collaborators 

 carries us into an experimental psychology that reaches 

 back of the data of the introspection of normal conscious- 

 ness.
