Figure-ground
36

Grouping
37

Depth perception
38
- a laboratory device for testing depth perception in infants and young animals
Visual cliff
39
- depth cues, such as retinal disparity, that depend on the use of two eyes
Binocular cues
40
- a binocular cue for perceiving depth: by comparing images from the retinas in two eyes, the brain computes distance (the greater the disparity between two images, the closer the object)
Retinal disparity
41
- depth cues, such as interposition and linear perspective, available to either eye alone
Monocular cues
42
- an illusion of movement created when two or more adjacent lights blink on and off in quick succession
Phi phenomenon
43
- perceiving objects as unchanging (having consistent shapes, size, brightness, and color) even as illumination and retinal images change
Perceptual constancy
44
- perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object

- in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch
Frequency theory
57
- the theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain / the “gate” is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain
