Question 1: volley principle

Answer:

refinement of the frequency theory; it suggests that receptors in the ear fire in sequence, with one group responding, that a second, third, and co on, so that the complete pattern of firing corresponds to the frequency of the sound wave

Question 2: decibel

Answer:

unit of measurement for the loudness of sounds

Question 3: hue

Answer:

the aspect of color that corresponds to names such as red, green, and blue

Question 4: optic nerve

Answer:

the bundle of axons of ganglion cells that carries neural messages from each eye to the brain

Question 5: additive color mixing

Answer:

the process of mixing light of different wavelengths to create new hues

Question 6: ground

Answer:

background against which a figure appears

Question 7: feature detectors

Answer:

specialized brain cells that only respond to particular elements in the visual field such as movement or lines of specific orientation

Question 8: autokinetic illusion

Answer:

the perception that a stationary object is actually moving

Question 9: bipolar cells

Answer:

neurons that have only one axon and one dendrite; in the eye, these neurons connect the receptors on the retina to the ganglion cells

Question 10: afterimage

Answer:

sense experience that occurs after a visual stimulus has been removed

Question 11: trichromatic theory

Answer:

the theory of color vision that holds that all color perception derives from three different color receptors in the retina (usually red, green, and blue receptors)

Question 12: motion parallax

Answer:

monocular distance cue in which objects closer that the point of visual focus seem to move in the direction opposite to the viwer's moving head, and objects beyond the focus point appear to move in the same direction as the viewer's head

Question 13: pupil

Answer:

a small opening in the iris through which light enters the eye

Question 14: monocular cues

Answer:

visual cues requiring the use of one eye

Question 15: lens

Answer:

the transparent part of the eye inside the pupil that focuses light onto the retina

Question 16: iris

Answer:

the colored part of the eye

Question 17: subtractive color mixing

Answer:

the process of mixing pigments, each of which absorbs some wavelengths of light and reflects others

Question 18: vestibular senses

Answer:

the sense of equilibrium and body position in space

Question 19: trichromats

Answer:

people who have normal color vision

Question 20: golgi tendon organs

Answer:

receptors that sense movement of the tendons, which connect muscle to bone

Question 21: amplitude

Answer:

the magnitude of a wave; in sound, the primary determinant of loudness

Question 22: figure

Answer:

entity perceived to stand apart from the background

Question 23: pitch

Answer:

auditory experience corresponding primarily to frequency of sound vibrations, resulting in a higher or lower tone

Question 24: light adaptation

Answer:

decreased sensitivity of rods and cones in bright light

Question 25: retinal disparity

Answer:

binocular distance cue based on the difference between the imagegs cast on the two retinas when both eyes are focused on the same object

Question 26: hammer, anvil, stirrup

Answer:

the three small bones in the middle ear that relay vibrations of the eardrum to the inner ear

Question 27: hertz (Hz)

Answer:

cycles per second; unit of measurement for the frequency of sound waves

Question 28: monaural cue

Answer:

cue to sound location that requires just one ear
