Unit 4.4 Psychology Flashcards
(16 cards)
Frequency
The number of complete wavelengths that pass a point in a given time
Audition
The sense or act of hearing
Pitch
A tone’s experienced highness or lowness; depends on frequency
Middle ear
The chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea’s oval window
Cochlea
A coiled, bony, fluid filled tube in the inner ear. Sound waves traveling through the cochlear fluid trigger nerve impulses
Inner ear
The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs
Sensorineural hearing loss
Hear loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; also called nerve deafness
Conduction hearing loss
Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
Cochlear implant
A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
Place theory
In hearing, the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated
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
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. The gate is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in large fibers or by information coming from the brain
Kinesthesia
The system for sensing the position and movement of individual body parts
Vestibular sense
The sense of body movement and position, including the sense of balance
Sensory interaction
The principle that one sense may influence another, as when the smell of food influences its taste
Embodied cognition
In psychological science, the influence of bodily sensations, gestures, and other states on cognitive preferences and judgements
