D) convergence

Question

Quizplus · Accepted Answer

Binocular rivalry occurs when the brain cannot fuse the different images from the two eyes into a single percept. Instead, the brain alternately suppresses one image and then the other, resulting in a conscious percept that appears to switch back and forth between the two images. Accommodation refers to the ability of the lens to adjust its shape to focus on objects at different distances, while binocular disparity refers to the slight differences in the location of the same object on the two retinas due to the slightly different angles from which each eye views the object. Convergence refers to the inward turning of the eyes as they focus on nearby objects.
