PSYCH QUIZ
Question | Answer |
---|---|
frequency | the number of complete wavelengths that pass a point in a given time (for example, per second). |
pitch | a tone’s experienced highness or lowness; depends on frequency. |
middle ear | the chamber between 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. |
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 | hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; the most common form of hearing loss, also called nerve deafness. |
conduction hearing loss | a less common form of 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 | the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated. |
frequency theory (also called temporal theory) | 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. |
olfaction | the sense of smell. |
kinesthesia | our movement sense—our system for sensing the position and movement of individual body arts. |
vestibular sense | our sense of body movement and position that enables our sense of balance. |
sensory interaction | the principle that one sense may influence another, as when the smell of food influences its taste. |
embodied cognition | the influence of bodily sensations, gestures, and other states on cognitive preferences and judgments. |
