Visual Cliff and Perception
|
-Presents infants with illusion of a large drop-off... willingness to cross is related to crawling experience.
-Novice = just crawls, no facial expression of fear. -1 mth experience = fear of heights |
|
Cues for Depth Perception
|
1. Optical Expansion
2. Binocular Disparity and Stereopsis 3. Pictorial/Monocular cues |
|
Optical Expansion
|
-Visual image of an object increases in size as the object comes toward us, occludes more of the background
-Expands symmetrically?.. coming for us = duck. -Babies cant duck. 1 mth = blink |
|
Binocular Disparity
|
-Two eyes, retinal image is not the same.
-Closer object = greater disparity, Further away = lower disparity. |
|
Stereopsis
|
-Cortex computes degree of disparity between differing neural signals, produces perception of depth
