PSYC 4365 Lecture Notes - Lecture 18: Random Dot Stereogram, Horopter, Stereoblindness
Document Summary
Binocular vision and stereopsis: vieth m ller circle: the location of objects whose images fall on geometrically corresponding points in the two retinas, horopter: the location of objects whose images lie on the corresponding points. The vieth m ller circle and the horopter are technically different, but for our purposes you may consider them the same. Figure 6. 25 bob is still gazing at the red crayon: objects on the horopter are seen as single images when viewed with both eyes. If visible in both eyes, stimuli falling outside of panum"s fusional area will appear diplopic. Images in front of the horopter are displaced to the left in the right eye and to the right in the left eye: uncrossed disparity: the sign of disparity created by objects behind the plane of the horopter. Images behind the horopter are displaced to the right in the right eye and to the left in the left eye.
