Unit 3 Flashcards
altering one’s existing schemas, or ideas, as a result of new information or new experiences
accomodation
your sense of hearing
audition
the point at which the optic nerve leaves the eye
blind spot
a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
cochlea
caused by damage to the system that conducts sound waves to the cochlea
conduction hearing loss
a type of photoreceptor that distinguishes colors and detects fine details in well-lit conditions
cones
transparent, protective outer layer of the eye that bends light waves to assist in proper focus.
cornea
nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
feature detectors
a small indentation at the center of the retina that contains the highest concentration of cones.
forvea
the number of complete wavelengths that pass a certain point in one second.
frequency
the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone; enabling us to sense its pitch
frequency theory
the spinal cord contains a “gate” that controls whether pain signals get sent to the brain or not
gate-control theory
the dimension of color that is determined by the wavelength of light
hue
the amount of energy in a light or sound wave which we perceive as brightness or loudness
intensity
a piece of muscle tissue that sits behind the cornea and helps the eye adjust how much light enters
iris
