[Cerebral psychophysiologic study of the processes brought into action by physical context modifications in the short-term recognition of images].
The study of P300 waves and reaction times during the acquisition and recognition of simple symbolic pictures (Signoret's test) shows the extent of "contextual effect" in visual short-term recognition. These results support the "encodage spécifique" theory according to which contextual changes between acquisition and restitution reduce memory efficiency.
