The present study compared discriminations of differences in speed to differences in temporal frequency and examined the role of directionally selective mechanisms in such discriminations. In measuring the contrast dependence of speed and temporal frequency discriminations two different techniques were used to reduce the role of directionally selective mechanisms. The first was the virtual elimination of directional selectivity in the visual cortex of cats by stroboscopic rearing. The second… CONTINUE READING
