Cyclopean vision

Show Summary Details

Preview

Images in the two eyes may be superimposed or juxtaposed to produce a perceptual effect not visible to either eye. Any such effect is known as a cyclopean effect. Stereoscopic vision is a cyclopean effect but there are many others, such as cyclopean figural effects, cyclopean motion, and cyclopean acuity. Another issue of cyclopean vision discussed in this chapter is how stimuli moving in different directions in the two eyes are unified into an impression of cyclopean motion in one direction. Another issue is how we combine the two images of an object to produce a coherent sense of the object’s direction. The chapter ends with a discussion of whether we are aware of which eye is seeing a stimulus presented to only one eye. This is known as utrocular discrimination.

Keywords: cyclopean vision; cyclopean motion; binocular direction; utrocular discrimination
