Some plain considerations about the neuropsychology of attention / Quelques remarques triviales sur la neuropsychologie de l'attention

Attentional processes have an effect on cerebral activities through several mechanisms: they regulate sensibility thresholds to external stimuli at various levels of signal integration (either increasing or decreasing thresholds); they activate already existing patterns of cortical activity, which anticipate external events; they inhibit or foster more or less automatized response patterns, testing whether ongoing cerebral activities are linked to environmental events or only to imaginary events. Then the teacher's task is to offer new situations or informations, but which may be sufficiently anticipated for the child to have time and ability to compare and update his anticipations according the suggested reality.
