Question

Quizplus · Accepted Answer

The phenomenon described in the scenario is an example of binocular disparity, which occurs because the eyes have slightly different views of the finger's position in space. When we alternate between the eyes, this difference creates the perception of the finger jumping back and forth. Option A, motion parallax, refers to the change in position of objects relative to our own movement, while option B, optic flow, is the pattern of visual motion created by objects moving through our visual field. Option D, interposition, refers to the perception of one object blocking or occluding another in our view.
