Summary
Numerous factors can influence the processing of pain message: the affective or emotional, the sensorial and the cognitive components. Interindividual variations at the emotional and cognitive levels may interfere with the pain message and the consecutive behavior. Some modifications in these components are observed in psychiatric troubles, but their influences on the behavior to pain have not been studied, although they have been studied in some populations characterized as non communicating, with obvious cognitive degradations (subject with dementia, older, newborns,…).In an other study in course, the past pain experience is explored in relation to results to experimental pain tests, emotional and anxious characteristics. This present pilot study aims at studying the infra-verbal behavioural signs during experimentally induced pain in subjects with schizophrenia, major depression, and controls.
