Chapter 19 Flashcards
(25 cards)
Pitch
A tones experienced hoghness or lowness; depends on frequency
Fequency
The nimber of complete wavelengths that pass a point at a given time
Middle ear
The champer between the eardrum and cochlea containg three tiny bones (hammar, anvil, stirrup) that concentrate the variations of the eardrum on yhe cochleas 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 inner most part of the ear, containing the cochlea, semicircular chanals, and vestibular sacs.
Sensorineural hearing lodd
Heating loss caused by damage ti the cochleas receptor calls or to the auditory nerves; also called nerve defness
Conduction hearing loss
Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.
Cochlea implants
A device for converting sounds into electrical signals and stimulating the auditory heave through electroddes threaded into the cochlea
Place theory
Inhearing, the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated
Fequency 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.
Kinesthesis
Your sense of position and movement of your body parts
Vestibular sense
The sense of body movement and position, including the sense of balance
Great amplitude
Small amplitude
Load sounds
Soft sounds
Short wavelength
Long wavelength
High frequency- high pitched sound
Low frequency- low-pitch sound
Embodied cognition
In psychological science, the influence of bodily sensations, gestures, and other states on cognitive preference and judgment
Which theory of pitch can hear high and low pitch
High pitch- place theory
Low pitch- frequency theory
Gate control theory
That theory that the spinal cord contains a neurological “gate” is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fivers or by infomation coming from the brain
Smell
1.odor bind to receptors 2. Ofactory cells are activated and send electric signals 3. The signals are relayed via converged axons. 4. The signals are transmitted to higher regions of the brain
Vision
Source: Light wave striking the eye.
Receptors: Rods and cones in the retina.
Hearing
Source: sound waves striking outer ear
Receptors: cochlear hair cells in the inner ear
Touch
Source: pressure, warmth, cold on the skin
Receptor: skin receptors detect pressure warmth cold and pain
Taste
Source: chemical molecukes in the mouth
Receptors: basic tongue receptrs for sweet sour salty bitter and umami
Smell
Source: chemical molecukes breathed in through the nose
Receptors millions of recetors at top of nasal cavity
Body position- kinesthesis
Source: any change in position of a body part, interacting with vision
Receptors: kinesthetic sensors all over yhe body
