Visually emitted potential and attentional processes.
Visually emitted potentials were recorded during a series of 450 stimulations with a frequency of 1 per second, during which 10% were voluntarily omitted by the experimenter, either regularly or at random. The recordings summed up here show the presence of a potential emitted in the form of a late positive wave (350 ms) preceded by a negative wave (200 ms) when the subject mentally counted the omissions (regular or random). This leads us to believe that the subject's attention is more determinant than the random distribution of omissions.
