What will be an ideal response? Title: Discuss two binocular cues we use for depth perception. Post by: mikeyp on Feb 13, 2018 Binocular cues depend on the different images presented to each eye. Retinal disparity, for example, involves the brain's ability to interpret differences in the retinal images present on each eye. These differences provide cues about how distant an object is from us. For example, closer objects produce greater disparity, whereas more distant objects produce less disparity. Convergence involves the tension
produced in eye muscles by turning both eyes inward to focus on a single image. Both eyes can be focused on a particular object, but this act produces tension in the muscles that move the eyes as the object draws closer. This tension, then, is used as a cue that indicates distance from observer to object. |
