title: Local and distal factors in visual grating induction.
abstract: When a uniform test field is surrounded by luminance or chromatic gratings, a grating is induced in the test field. The perceived spatial frequency and orientation of the induced grating can be different from the frequency and orientation of the inducing gratings. Local edge effects are the factors primarily responsible for visual grating induction. Distal parts of the inducing stimulus affect only the amplitude of the induced modulation.
