Question

Quizplus · Accepted Answer

Adapting to a vertical grating of 1 cycle/degree specifically reduces the sensitivity to other gratings of the same orientation and spatial frequency, making a 1 cycle/degree vertical grating of near threshold contrast appear to have less contrast. This is due to the orientation and spatial frequency specificity of the adaptation effect in the visual system.
