Abstract

Amplitude characteristics of visually evoked potentials to alphanumeric and checkerboard stimuli were examined in this experiment. Subjects, 17 male college students, were exposed to a series of trials consisting of the presentation of seven successive stimuli-a warning stimulus (WS) followed by a first triplet of three identical stimuli (stimulus positions 1-3) and a second triplet of another three identical stimuli (position 4-6). A subject's task was either to report the numbers presented (verbal task) or match the checkerboard patterns (non-verbal task) in the two triplets. Each stimulus was illuminated by two 20 μs discharges of xenon tubes with the interval of either 25 or 50 ms. Analysis of occipital P260 amplitudes revealed significant differences between WS and position 1 for both alphanumeric and checkerboard stimuli when the interval between two 20 μs discharges was 50 ms but not when it was 25 ms. These findings indicated that there may be a critical interval between 25 and 50 ms which is effective in producing task specific perceptual activities at position 1.
