Jody's horse looks just as black in the brilliant sunlight as it does in the dim light of the stable.This illustrates what is known as

A) interposition.
B) accommodation.
C) brightness constancy.
D) continuity.

Brightness constancy refers to the ability of our visual system to perceive an object as having a constant color and brightness despite changes in the lighting conditions. In this case, the horse appears just as black in both bright sunlight and dim stable light because our visual system is able to adjust for the changes in lighting and maintain the perception of constancy. Interposition refers to when one object overlaps another, accommodation refers to the adjustment of the lens in the eye to focus on objects at different distances, and continuity refers to the tendency for objects to be perceived as continuous even when they are partially obscured. None of these concepts are relevant to this scenario.
