D)opponent process

Question

Quizplus · Accepted Answer

Retinal disparity refers to the slight difference between the images received by the left and right eye. In random-dot stereograms, two slightly different images are presented to each eye, with the dots within each image being randomly distributed. The brain integrates the two images to create the perception of depth, based on the differences in position of the dots in each image. This is known as stereopsis, and is a powerful cue for depth perception in humans. Therefore, the best choice is A) retinal disparity.
