Abstract: The study examined whether motor set, along with perceptual set, produces precortical short-latency poststimulus effects in the visuo-motor system. Eighteen subjects participated in a spatial selective attention paradigm developed by Eason, Harter, and White in 1969. Spots of light were presented concomitantly 30 degrees peripherally in the right and left visual fields. The stimuli were presented either as a single flash or as two flashes (doublets). Subjects were required to make one of three types of responses to the doublets presented in the relevant field: (1) an eye movement, (2) a foot lift response, or (3) silent counting. VERs were recorded at frontal and parietal areas of each hemisphere.
