The ability to adjust to changed sensory input is called

A) retinal disparity.
B) accommodation.
C) perceptual adaptation.
D) shape constancy.

Perceptual adaptation refers to the brain's ability to adjust to altered sensory input, such as when wearing glasses that correct for astigmatism or when walking in a tilted environment. Retinal disparity refers to the slight difference in the visual field of each eye that allows for depth perception. Accommodation refers to the ability of the lens of the eye to change shape to focus on near or far objects. Shape constancy refers to the ability to perceive an object as maintaining its shape even when viewed from different angles.
