Module 19-21 Flashcards
(28 cards)
an organized whole
gestalt
the organization of the visual field into objects that stand out from their surroundings
figure-ground
the perceptual tendency to organize stimuli into coherent groups
grouping
the ability to see objects in three dimensions, allows us to judge distance
depth perception
a laboratory device for testing depth perception
visual cliff
depth cues that depend on the use of two eyes
binocular cues
a binocular cue for perceiving depth
retinal disparity
depth cues available to either eye alone
monocular cues
an illusion of movement created when two or more adjacent lights blink on and off in quick succession
phi phenomenon
perceiving objects as unchanging even as illumination and retinal images change
perceptual constancy
perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object
color constancy
in vision, the ability to adjust to an artificially displaced or even inverted visual field
perceptual adaptation
the sense or act of hearing
audition
the number of complete wavelengths that pass a point in given time
frequency
a tones experienced highness or lowness
pitch
the chamber between the eardrum and cochlea containing the hammer, anvil and stirrup
middle ear
a coiled, bony, fluid filled tube in the inner ear
cochlea
the innermost part of the ear
inner ear
hearing loss caused by damage to the cochlea receptors cells or to the auditory nerves
sensorineural hearing loss
hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
conduction hearing loss
a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
cochlear implant
in hearing, the theory that links the pitch we hear with the place where the cochleas membrane is stimulated
place theory
the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone
frequency theory
the theory that the spinal cord contains a neurological gate that clocks pain signals or allows them to pass on to the brain
gate-control theory
