Anticipation of Relevant Stimuli and Evoked Potentials: A Reply to Naatanen

Abstract
Naatanen's comments on Donchin and Cohen's study of selective attention seem to derive from a failure to appreciate the relationship between the negative shifts in cortical potentials reported by Naatanen, and Grey Walter's CNV. Naatanen's assertion that slow negative cortical shifts reflect generalized cortical activation is discussed.
