TL;DR

Subjects were presented with two gratings with different spatial frequencies and they were asked to discriminate one from the other, finding that at high spatial frequencies, discrimination deteriorates when differences of subjective contrast are eliminated.

Abstract

Subjects were presented with two gratings with different spatial frequencies and they were asked to discriminate one from the other. Their ability to discriminate between the gratings was found to depend primarily on the ratio of their spatial frequencies over a wide range of absolute frequency. At high spatial frequencies, discrimination deteriorates when differences of subjective contrast are eliminated.
