Communication verbale et pathologie post-traumatique : interactions conversationnelles avec une patiente souffrant de lésions bifrontales

Abstract : Pervasive social maladaptation in a patient (AB) suffering from bilateral orbitofrontal lesions due to traumatic head injury is observed during conversations. The patient chats with her mother (M), then with 2 familiar neuropsychologists (NPS). In the control situation, one of the NPS chats with M. The speech acts and their properties are analysed according to the theory of the illocutionary logic (Searle et Vanderveken, 1985) as applied to the conversational interactions by Trognon and Ghiglione (1993) and adapted to our case. The comparisons of the speakers in each of the three experimental conversations show that the patient uses more often assertive and direct speech acts when her partners use directive ones, either direct (questions) or indirect (orders or requests). The patient allows for less success when the directive acts are indirect than when they are direct ; but once success is allowed, satisfaction follows in most cases. The acts of the partners are more often directive when they speak to the patient than when they talk together ; their satisfactions are balanced when they speak together but both get more satisfactions when they talk to the patient. The result may be interpreted according to a pathology of the supervisory attentional system (SAS) as conceptualized by Shallice and Bugess (1991) : the assertive and direct speech acts as well as the success of the satisfied acts could be managed with little control of the supervisory attentional system (SAS) when indirect acts which imply complex operations of inference could need more cognitive ressources of the SAS. The conversational behavior of the patient may be related to a dysfunction of the SAS due to the bilateral orbitofrontal lesions.
