Perception

Answer 2

The process of organizing and interpreting sensory information

Question 3

Question 7

Fovea

Answer 7

Central region of the retina

Question 8

Perceptual Constancy

Answer 8

The perception of objects as being of constant size, shape, color, etc in spite of physical differences in the retinal image of the object

Question 9

Answer 9

The identification of separate objects in a visual array

Question 10

Optical Expansion

Answer 10

A depth cue in which an object occludes increasingly more of the background, indicating that the object is approaching

Answer 11

The difference between the retinal image of an object in each eye that results in two slightly different signals being sent to the brain

Question 12

Stereopsis

Answer 12

The process by which the visual cortex combines the differing neural signals caused by binocular disparity, resulting in the perception of depth
