Abstract
We argue that probability effects on P300 amplitude are the product of an automatic frequency detector not subject to voluntary control and relatively inaccessible to consciousness. ''Expectancies'' related to P300 therefore appear to be passive, perceptual ones. If probability-b ased expectancies do become conscious, they are inversely related to P 300, supporting the view of Donchin & Coles (1988).
