Event-Related Potentials in the Study of Sensory Discrimination and Motor Response in Simple and Choice Reaction Tasks

Abstract
The central organization of the so-called stages of information processing and, in particular, whether such processes proceed serially or in parallel is controversial. Many investigators have considered such organization is substantially serial, although new evidence implies the existence of parallel overlapping processes in which the boundaries between the different stages of information processing are quite blurred. Such evidence derives in part from computer-assisted analysis of the brain's electrical activity.
