Focusing of conscious awareness on a particular stimulus and blocking out all other stimuli.

 The system for sensing the position and movement of individual body parts.

 Retinal receptors that detect black, white, and gray and that work best in dim light.

Perceiving objects as unchanging, even as illumination and retinal images change

Diminishing sensitivity to a constant, unchanging stimulus.

Theory that links the pitch we hear to the rate of the cochlea’s hair cell vibrations.

Principle that one sense may influence another.

The minimum difference between two stimuli required for detection 50% of them time.

Below one’s absolute threshold for conscious awareness.

A mental predisposition to perceive one thing and not another.

The sense or act of hearing

Theory that the retina contains three different color receptors – red, green and blue.

The process of organizing and interpreting sensory information.

Our tendency to integrate pieces of info into meaningful wholes

A process that begins with the sensory receptors and works up to the brains integration of sensory information.

constructs perceptions from sensory input by drawing on your experience and expectations

The minimum stimulus energy needed to detect a stimulus 50% of the time.

Below ones absolute threshold for conscious awareness.

The minimum difference between two stimuli required for detection 50% of the time.

A mental predisposition to perceive one thing and not another.

The controversial claim that perception can occur apart from the sensory inputs.

The distance from the peak of one light or sound wave to the peak of the next.

The amount of energy in a light or sound wave, which influences what we perceive as brightness of loudness.

The dimension of color that is determined by the wavelength of light

The eyes clear, protective outer layer, covering the pupil and iris

The adjustable opening in the center of the eye where the light enters

A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening

The transparent structure behind the pupil that changes shape to help focus images on the retina

The light sensitive inner surface of the eye, containing receptor rods and cones plus layers of neurons that begin the processing of visual information.

(1.) The process by which the eyes lens changes shape to focus on near or far objects

The nerve that carries neural impulses from the eye to the brain

The point at which the optic nerve leaves the eye

The central focal point in the retina, around which, the cones cluster

Perceiving objects as unchanging even as illumination and retinal images change

The theory that the retina contains three different color receptors - one most sensitive to red, one to green, and one to blue - which when stimulated in combination can produce the perception of any color

The theory that opposing retinal processes (red-green; blue-yellow; white-black) enable color vision. For Example some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green

The organization of the visual field into objects that stand out from their surroundings.

An illusion of movement created when two or more adjacent lights blink on and off in quick succession

Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelength reflected by the object

The number of completed wavelengths that pass a point in a given time

A tones highness or lowness depending on frequency

The chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea's oval window

A coiled, bony, fluid filed tube in the inner ear

The part of the ear containing the cochlea, semi-circular canals, and vestibular sacs

hearing loss caused by damage to the cochlea's receptor cells or the auditory nerves; the most common form of hearing loss.

A less common form of hearing loss, caused by damage to the mechanical system that conducts soundwaves to the cochlea

The theory that the spinal cord contains a neurological gate that blocks pain signals or allows them to pass on to the brain.

The sense of smell

Our system for sensing the position and movement of individual body parts

Our sense of gravity and balance

The principle that one sense may influence another.
