|Schizophrenia Major Depression||Other: pain tests|
The objective is to search for behavioral non verbal indicators of pain during experimentally induced pain (pressure application, ischemia induction).
Included subjects are subjected to experimental pain tests : pressure application (160 kPa) with an algometer to determine the pain with Visual Analogic Scale (VAS), and ischemia induction to determine the time needed to feel pain with an intensity equivalent to 3 with the VAS.
Subjects are filmed during experimentation to identify the corporal mobility signs, facial expression signs and sonorous signs associated to pain stimulation.
Neurophysiological measures complete these observations : surface electromyogram, heart rate measure, blood pressure.
