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.
