psych 4-3

process of creating meaningful patterns from raw sensory information.

apparent movement caused by flashing lights in sequence, as on theater marquees.

auditory experience corresponding primarily to frequency of sound vibrations, resulting in a higher or lower tone.

theory that pitch is determined by the location of greatest vibration of the basilar membrane.

small opening in the iris through which light enters the eye.

a specialized cell that responds to a particular type of energy.

lining of the eye containing receptor cells that are sensitive to light.

binocular distance cue based on the difference between the images cast on the two retinas when both eyes are focused on the same object.

receptor cells in the retina responsible for night vision and perception of brightness.

the vividness or richness of a hue.

structures in the inner ear particularly sensitive to body rotation.

experience of sensory stimulation.

tendency to see an object as the same shape no matter what angle it is viewed from.

perception of an object as the same size regardless of the distance from which it is viewed.

A psychological experience created by the brain in response to changes in air pressure that are received by the auditory system.

changes in pressure caused when molecules of air or fluid collide with one another and then move apart again.

combination of two retinal images to give a three-dimensional perceptual experience.

receptors that sense muscles stretch and contraction.

apparent movement that results from flashing a series of still pictures in rapid succession, as in a motion picture.

the process of mixing pigments, each of which absorbs some wavelengths of light and reflects others.

structures on the tongue that contain the receptor cells for taste.

monocular cue to distance and depth based on the fact that the higher on the horizontal plan an object is, the farther away it appears.

the quality or texture of a sound caused by overtones.

perceptual analysis that emphasizes the perceiver’s expectations, concept memories, and other cognitive factors, rather than being driven by the characteristics of the stimulus.

transformation of one form of energy into another – especially the transformation of stimulus information into nerve signals by the sense organs.

Theory of color vision that all color perception derives from three different color receptors in the retina (usually red, green, and blue receptors).

people who have normal color vision.

sacs in the inner ear that are responsible for sensing gravitation and forward, backward, and vertical movement.

sense of equilibrium and body position in space.

the tiny part of the electromagnetic spectrum to which our eyes are sensitive.

the ability to distinguish fine details.

location of receptors for pheromones in the roof of the basal cavity.

refinement of frequency theory; receptors in ear fire in sequence, one group, then another, etc., complete pattern of firing corresponds to the frequency of sound.

the different energies represented in the electromagnetic spectrum.

the principle that the just noticeable difference for any given sense is a constant proportion of the stimulation being judged.
