The McCollough effect: Influence of several kinds of visual stimulation on decay rate

Abstract

An experiment was conducted to determine whether the decay rate of the McCollough effect could be differentially influenced by the type of visual stimulation that followed its induction. After acquiring this effect, Os were exposed to achromatic gratings, homogeneous chromatic fields, natural visual stimulation, or complete darkness. Exposure to achromatic gratings caused a marked fading of the effect; the other types of stimulation were associated with similar and much less rapid decay. © 1974 Psychonomic Society, Inc.
