Retinal disparity is necessary for the process of
A) brightness sensitivity.

D) stereopsis.
E) blue-yellow color vision.

Question

Quizplus · Accepted Answer

Retinal disparity refers to the difference in the images projected on the right and left retinas, which is a crucial cue for depth perception and the ability to perceive objects in three dimensions. This process is known as stereopsis, and is essential for tasks such as judging distances, catching objects, or navigating through space. Therefore, D) stereopsis is the best choice for the process that relies on retinal disparity. The other options are not directly related to retinal disparity, as brightness sensitivity and negative afterimages involve the activity of photoreceptor cells, relative retinal size relates to the size of objects and their distance, and blue-yellow color vision is mediated by different types of cone cells in the retina.
