Brightness constancy is most clearly facilitated by
A) proximity.
B) interposition.
C) relative luminance.
D) retinal disparity.

Question

Quizplus · Accepted Answer

Brightness constancy refers to our ability to perceive an object as having a consistent level of brightness even as the amount of light it reflects changes due to changes in illumination. Relative luminance is the property that allows us to compare the brightness of different objects and determine which is brighter or darker than the other. Therefore, relative luminance facilitates brightness constancy. Proximity, interposition, and retinal disparity are related to depth perception, not brightness constancy.
