PSYCH 2 Lecture Notes - Lecture 8: Color Constancy, Ear Pick, 3D Film
Document Summary
Represents ability to see objects in 3d even though image that strikes retina is 2d. Visual cliff: test of early 3d perception. Most infants refuse to crawl over visual cliff. Binocular cues: cues for depth perception that use both eyes. Brain calculates distance by comparing images from retinas in 2 eyes. Monocular cues: for depth perception that uses 1 eye. Perceived as unchanging even as retina images change.

Sound waves: from environment into the brain. Tiny bones in middle of ear pick up vibrations and transmit to cochlea (coiled fluid-filled tube in inner ear) Ripples in fluid bend hair cells lining surface which trigger impulse in nerve cells. Axons from these nerve cells transmit signal to auditory cortex. Sound waves strike one ear sooner and more than other. Ex. think how owls use this for prey.
