Activité électrodermale spontanée et variations de l’état affectif

Abstract
The systematic recording of spontaneous electrodermal activity (EDA) on 23 normal subjects during 5 15-min sessions and the self-rating of anxious and/or depressive moods (Q-sort forced choice) shows a positive linear relationship between spontaneous EDA and anxious mood despite a low covariation between those two variables. The same relationship is found with a lower degree of confidence in depression. A greater EDA is observed in the rare pattern of ‘depression higher than anxiety’, than in the opposite case. The discussion of the results deals with the parallelism between a physiological continuum and affective states.
