the ability of the body to adapt to an environment by filtering out distractions

Answer 3

the tendency of animals and humans to see familiar objects as having standard shape, size, color, or location regardless of changes in the angle of perspective, distance, or lighting

Question 4

Phi Phenomenon

Answer 4

an optical illusion in which stationary objects shown in rapid succession, transcending the threshold at which they can be perceived separately, appear to move

Question 5

Monocular Cues

Answer 5

the way each eye individually takes in information

Question 6

Interposition

Answer 6

a type of monocular cue in which one object partially obscures or covers another object, giving the perception the object that is partially covered is farther away

Question 7

Retinal Disparity

Answer 7

the depth perceived between two objects as each eye individually receives them

Question 8

Binocular Cues

Answer 8

dept cues that require the use of both eyes

Question 9

Depth Perception

Answer 9

the ability to see objects in 3d

Question 10

Closure

Answer 10

the illusion of seeing an incomplete stimulus as though it were whole

Question 11

Figure Ground

Answer 11

the ability to differentiate an object from its background

Question 12

Olfactory Nerve

Answer 12

nerve that enables your sense of smell

Question 13

Auditory Nerve

Answer 13

transmits hearing impulses from the ear to the brain

Question 14

Selective Attention

Answer 14

the focusing of a conscious awareness on a particular stimulus (the cocktail party effect)

Question 15

Sensory Interaction

Answer 15

occurs when various senses work together

Question 16

Young Helmholtz Theory

Answer 16

trichromatic color theory - there are three different retinal color receptors (red, green, and blue)

Question 17

Opponent Theory

Answer 17

opposing retinal processes enable color vision (color blindness)

Question 18

Parallel Processing

Answer 18

simultaneous processing of several aspects of a problem simultaneously

Question 19

Blind Spot

Answer 19

the point where the optic nerve leaves the eye since there are no receptor cells located there

Question 20

Feature Detector

Answer 20

nerve cells in the brain that respond to specific features (shapes, angles, movement)

Question 21

Super Cell Clusters

Answer 21

teams of cells that respond to complex patterns

Question 22

Fovea

Answer 22

central point in the retina where the eye’s cones cluster

Question 23

Change Blindness

Answer 23

failing to notice changes in an environment

Question 24

Gate Control Theory

Answer 24

spinal cord contains neurological “gate” that prevents or allows pain signals to pass through (typically one at a time)

Question 25

Vestibular Sense

Answer 25

monitors the body’s position in relation to gravity

Question 26

Kinesthesis

Answer 26

sensing the position and movement of individual body parts

Question 27

Amplitude

Answer 27

tall amplitude = bright colors and loud sounds
short amplitude = dull colors and soft sounds

Question 28

Conductive Deafness

Answer 28

caused by damage to the cochlea’s receptor cells in the middle ear (hearing aids can be used)

Question 29

Sensorineural Deafness

Answer 29

caused by damage to the auditory nerve (disease or loud sounds)

Question 30

Place Theory

Answer 30

recognizes the place on the cochlea that is generating a neural signal (high frequency at beginning and low frequency at end)
*high pitches

Question 31

Frequency Theory

Answer 31

the rate of nerve impulses traveling up the auditory nerve matches frequency and helps us sense pitch
*low pitches

Question 32

Inner Ear

Answer 32

transforms vibrations into electrical impulses that travel along the auditory nerve to the brain

Question 33

Middle Ear

Answer 33

transmits sounds from the outer ear to the inner ear

Question 34

Outer Ear

Answer 34

collects sound waves and channels them into the ear canal

Question 35

Cochlea

Answer 35

plays a key role in hearing and auditory transduction (inner ear)

Question 36

Stirrup

Answer 36

helps the conduction of sound vibrations to the inner ear (in the middle ear)

Question 37

Anvil

Answer 37

transmits vibrations from the malleus to the stapes (three small bones in the middle ear)

Question 38

Hammer

Answer 38

helps in the transmission of sound waves

Question 39

Ear Drum

Answer 39

sends vibrations to the inner ear

Question 40

Frequency

Answer 40

the number of waves that pass a fixed place in a given amount of time

Question 41

Pitch

Answer 41

frequency of a sound wave

Question 42

Decibel

Answer 42

measure of sound intensity

Question 43

Lens

Answer 43

transparent structure behind the pupil that changes shape to focus images on the retina

Question 44

Hue

Answer 44

determined by wavelength distance from peak to peak

Question 45

Wavelength

Answer 45

short = high frequency (blue and high pitched)
long = low frequency (red and low pitched)

Question 46

Weber’s Law

Answer 46

to perceive as different, two stimuli must differ by a constant minimum percentage

Question 47

Priming

Answer 47

exposure to stimulus that establishes a relationship to a second stimulus

Question 48

Absolute Threshold

Answer 48

minimum stimulation needed to detect a particular stimulus 50% of the time

Question 49

Intensity

Answer 49

determines brightness and loudness by the height of peaks in wavelengths

Question 50

Bottom-Up Processing

Answer 50

stimulus begins with the sense receptors and works up to the level of the brain and mind

Question 51

Top Down Processing

Answer 51

higher level mental processes that draw on out experience and expectations

Question 52

Prosopagnosia

Answer 52

complete sensation in the absence of perception
