The sense or act of hearing
The number of complete wavelengths that pass a point in a given time
A tone's experienced highness or lowness, depends on frequency
the chamber bewteen the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window
A coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs
In hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated
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.
Conduction hearing loss
Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
Sensorineural hearing loss
Hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves; also called nerve deafness.
A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
The system for sensing the position and movement of individual body parts
The sense of body movement and position, including the sense of balance
Spinal cord gas a neurological "gate" that blocks pain signals/allows them to go to the brain. The "gate" is opened by activity of pain signals traveling up nerve fibers and is closed by activity in larger fibers or by info coming from brain.
The principle that one sense may influence another, as when the smell of food influences its taste
an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.
the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground)
The perceptual tendency to organize stimuli into coherent groups.
The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance
A lab device for testing depth perception in infants and young animals
Depth cues, such as retinal disparity, that depend on the use of two eyes.
A binocular cue for perceiving depth. By comparing images from the retinas in the two eyes, the brain computes distance--the greater the disparity (difference) between the two images, the closer the subject.
Depth cues, such as interposition and linear perspective, available to either eye alone.
An illusion of movement created when two or more adjacent lights blink on and off in quick succession
Perceiving objects as unchanging (having consistent shapes, size, lightness, and color) even as illumination and retinal images change
Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object.
In vision, the ability to adjust to an artificially displaced or even inverted visual field.
A mental predisposition to perceive one thing and not another.
the controversial claim that perception can occur apart from sensory input; includes telepathy, clairvoyance, and precognition
the study of paranormal phenomena including ESP and psychokinesis
