Eye movements during discrimination of simultaneously presented random textures pairs, differing in increasing mutual transitional probability, were recorded. Increase of difference in the "grain" between images resulted in reduction of crossing eye movements, while the number of saccadic eye movements within each image prior crossing eye movements decreased only slightly. The mean fixation time did not change at all. The principal factor determining the latencies of discrimination was the number of crossing eye movements. The schematized process of discrimination covering several steps is suggested.
