Document Summary

Psyc 212 lecture 9 february 8th. Vision 6: space and binocular vision ii/ vision 7: perceiving movement. Monocular to binocular cues: two types of cues that fall between monocular and binocular cues: (1) has to do with accommodation one of the functions of the lens is to focus the image on the retina. Divergence: ability of the two eyes to turn outward, often used to focus on objects that are further away. An advantage that comes with frontal vision is binocular summation: the (cid:272)o(cid:373)(cid:271)i(cid:374)atio(cid:374) (cid:894)o(cid:396) (cid:862)su(cid:373)(cid:373)atio(cid:374)(cid:863)(cid:895) of sig(cid:374)als f(cid:396)o(cid:373) ea(cid:272)h eye in ways that make performance on many tasks better with both eyes than with either eye alone. This is the main reason that drove evolution to generate organisms to have frontal vision. Frontal vision was also accompanied by binocular disparity: the differences between the two retinal images of the same scene.
