- sensory interactions
- the principle that one sense may influence another, as when the smell of food influences the taste
- frequency theory
- 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
- audition
- the sense of hearing
- sensory restriction
- includes loss of a sense such as sight, resulting in increase perception in other senses
- inner ear
- the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs
- loudness
- the preception of the amplitude of a sound wave, the precption of the amplitude of a sound wave
- Basilar membrane
- a membrane in the cochlea that supports the Organ of Corti
- conduction hearing loss
- hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
- pinna
- the outer ear
- hair cells
- vibrate sending a signal to the auditory nerve
- place theory
- in hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated
- the cocktail party effect
- the ability to attend selectively to only one voice among many
- frequency
- the number of complete wavelengths that pass a point in a given time
- sensorineural hearing loss
- hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves
- middle ear
- the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window
- selective attention
- the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect
- timbre
- the complexity of the sound
- organ of corti
- the hearing organ of the inner ear
- kinesthesis
- the system for sensing the position and movement of individual body parts
- Gate-control theory
- the theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows them to pass on to the brain
- pitch
- a tone's highness or lowness; depends on frequency
- cochlea
- a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
- vestibular sense
- the sense of body movement and position, including the sense of balance
