Document Summary

Patients who have suffered damage to the occipital-parietal pathway have difficulty reaching in the correct direction to retrieve the toothbrush. Objects that block another object are closer to you. As things are farther from you, they become more fuzzy/blurry. Top-down and bottom-up processing: top-down, some degree of knowledge of the world, bottom-up, things that happen on the retina. When a something appears larger, they are closer. As things are farther away they will eventually disappear. When there are many things, when things appear closer together we assume they are farther away. Texture gradient becoming finer and finer: less defined &separate from one another. When something is higher in the sky we assume it is closer. When something is lower on the ground we assume it is closer. Things move faster as they are closer to you. Two eyes (stereopsis: each perceives the scene at a slight different angel. Retinal disparity is a powerful indicator of depth.
