Abstract

This paper is devoted to an investigation of the parameters that specify the spatial adjustment of visual mechanisms sensitive to contrast modulation. The bands for tuning to the spatial frequency, phase, and orientation of the envelope were determined. The masking paradigm was used to solve this problem. It is found that band-pass tuning applies to all the indicated parameters. The width of the transmission bands in the problem of detecting contrast modulation proved to be somewhat wider than for the mechanisms that are sensitive to brightness modulation.
