Abstract
Do unconscious stimuli modify processes that are typically associated with consciousness? This question is of particular interest in schizophrenia in which there is both impairments of implicit processes and abnormalities of conscious processes. For instance patients have difficulties to initiate a strategy or to feel in control of their actions. For this purpose, we wanted to know to what extent the choice of a task set or the feeling of control over the action could be influenced by unconscious cues. We conducted two studies in healthy subjects showing that unconscious stimuli can influence the preparation of a task set. However, we have shown that there are limitations to these unconscious influences: the processing of unconscious stimuli must be uninterrupted for some time, and it is modulated by attentional mechanisms. Our third study analyzed the effect of subliminal distortions of the haptic feedback (tactile and kinesthetic) on motor adaptation and on the conscious sense of control over the action. We have shown that the feeling of control was modulated by subliminal distortions of the haptic feedback. Unconscious influences have an impact on conscious processes, but in limited and controlled circumstances.

Cette question est d’un intérêt particulier dans la schizophrénie où il existe à la fois des anomalies de processus implicites et des anomalies de processus conscients, comme par exemple, initier une stratégie ou se sentir en contrôle de son action. Pour réaliser des études chez les patients, nous devions savoir dans quelle mesure le choix d’une stratégie ou le sentiment de contrôler son action sont soumis à des influences non conscientes. Nous avons réalisé deux études chez le sujet sain montrant qu’un stimulus non conscient peut influencer la préparation d’une stratégie. Cependant, il existe des limites à ces influences non conscientes : le traitement du stimulus non conscient ne doit pas être interrompu trop tôt, et des filtres attentionnels le modulent. Notre troisième étude a analysé l’effet de distorsions subliminales du retour haptique (tactile et kinesthésique) sur l’adaptation motrice et sur le sentiment conscient de contrôler son action. Nous avons montré que le sentiment de contrôler l’action était modulé par des distorsions du retour haptique, même quand celui-ci est subliminaire. Les influences non conscientes ont un impact sur les processus habituellement conscients, dans des circonstances limitées et contrôlées.</abstract></profileDesc></hal></record>Pour manipuler ce document sous Unix (Dilib)
