Abstract
Previous studies have shown that motion perception is degraded when the visual stimulus is stroboscopically illuminated. The present experiment indicated that the accuracy in discrimination of the orientation of an intermittently presented stationary grating is unaffected by flicker rate. In addition, the orientation aftereffect induced by successive display of a tilted and vertical grating is independent of the flicker rate of each stimulus. These results indicate that mechanisms engaged in neural representation of contour information are not conjointly sensitive to the rate of temporal intermittency within the visual display.
