Document Summary

Binocular cues - retinal disparity (eyes are 2. 5 inches apart). Convergence things far away, eyes are relaxed. Hearing - inner ear muscle: higher noise = contract. Proprioception mice raised upside down would accommodate over time, and flip it over. Light adaptation, pupils constrict, rods and cones become desensitized to light) and upregulation (dark adaptation, pupils dilate) 2 vs. 2. 05 lb weight feel the same. 2 vs. 2. 2 lb weight difference would be noticeable. The threshold at which you"re able to notice a change in any sensation is the just noticeable difference (jnd) So now take 5 lb weight, in this case if you replace by 5. 2 weight, might not be noticeable. But if you take a 5. 5 lb it is noticeable. I = intensity of stimulus (2 or 5 lb), delta i = jnd (0. 2 or 0. 5). Weber"s law is delta i to intensity is constant, ex. 2/2 = . 5/5 = . 1: delta i/i = k (weber"s law)
