TEMPORAL MECHANISMS ASSOCIATED WITH INFORMATION PROCESSING BY THE VISUAL SYSTEM
Abstract
The response of the visual system to complex intermittent stimulation was investigated. The stimuli consisted of repeatedly alternating trains of square-wave pulses. Both the number and period of the pulses is the two alternating trains were varied under more than 450 experimental conditions. Criterion measurements of fusion were obtained for each of two observers for all conditions. The stimulus waveforms at threshold were analyzed, and the frequency andAMPLITUDE OF THE FUNDAMENTAL OBTAINED. Analysis was facilitated by use of an IBM 7070 computer. The resultant data were plotted in the form of amplitude-sensitivity curves for the two observers, and were found to be consistent with the view that the visual system operates as a lowpass filter.
