Module 3 pt 2

Question 1

interaural level difference:

Answer 1

sound coming from one side of the body is more intense at the closest ear because of the attenuation of the sound wave as it passes through the head

Question 2

interaural timing difference:

Answer 2

small difference in the time at which a given sound wave arrives at each ear

Question 3

Ménière’s disease:

Answer 3

results in a degeneration of inner ear structures that can lead to hearing loss, tinnitus, vertigo, and an increase in pressure within the inner ear

Question 4

monaural cue:

Answer 4

one-eared cue to localize sound

Question 5

place theory of pitch perception:

Answer 5

different portions of the basilar membrane are sensitive to sounds of different frequencies (higher frequencies)

Question 6

sensorineural hearing loss:

Answer 6

failure to transmit neural signals from the cochlea to the brain

Question 7

temporal theory of pitch perception:

Answer 7

sound’s frequency is coded by the activity level of a sensory neuron (lower frequencies)

Question 8

vertigo

Answer 8

spinning sensation

Question 9

closure

Answer 9

organizing our perceptions into complete objects rather than as a series of parts

Question 10

figure-ground relationship:

Answer 10

segmenting our visual world into figure and ground

Question 11

Gestalt psychology:

Answer 11

field of psychology based on the idea that the whole is different from the sum of its parts

Question 12

good continuation:

Answer 12

we are more likely to perceive continuous, smooth flowing lines rather than jagged, broken lines

Answer 13

ability to discriminate among different figures and shapes

Question 14

perceptual hypothesis:

Answer 14

educated guess used to interpret sensory information

Question 15

proximity:

Answer 15

things that are close to one another tend to be grouped together

Question 16

similarity:

Answer 16

things that are alike tend to be grouped together

Question 17

cross modal phenomena

Answer 17

effects that concern the influence of the perception of one sensory modality on the perception of another

Question 18

double flash illusion

Answer 18

the false perception of two visual flashes when a single flash is accompanied by two auditory beeps

Question 19

integrated

Answer 19

: the process by which the perceptual system combines information arising from more than one modality

Question 20

McGurk effect:

Answer 20

an effect in which conflicting visual and auditory components of a speech stimulus result in an illusory perception

Question 21

multimodal:

Answer 21

of or pertaining to multiple sensory modalities

Question 22

multimodal perception:

Answer 22

the effects that concurrent stimulation in more than one sensory modality has on the perception of events and objects in the world

Question 23

multimodal phenomena

Answer 23

effects that concern the binding of inputs from multiple sensory modalities

Answer 24

type of sense; for example, vision or audition

Question 25

unimodal:

Answer 25

of or pertaining to a single sensory modality

Question 26

olfactory bulb

Answer 26

: bulb-like structure at the tip of the frontal lobe, where the olfactory nerves begin

Question 27

olfactory receptor:

Answer 27

sensory cell for the olfactory system

Question 28

pheromone

Answer 28

Chemical message sent by another individual

Question 29

taste bud:

Answer 29

grouping of taste receptor cells with hair-like extensions that protrude into the central pore of the taste bud

Question 30

umami:

Answer 30

taste for monosodium glutamate

Question 31

congenital insensitivity to pain (congenital analgesia):

Answer 31

genetic disorder that results in the inability to experience pain

Question 32

inflammatory pain:

Answer 32

signal that some type of tissue damage has occurred

Question 33

Meissner’s corpuscle:

Answer 33

touch receptor that responds to pressure and lower frequency vibrations

Merkel’s disk:

Answer 34

touch receptor that responds to light touch

Question 35

neuropathic pain:

Answer 35

pain from damage to neurons of either the peripheral or central nervous system

Question 36

nociception:

Answer 36

sensory signal indicating potential harm and maybe pain

Question 37

Pacinian corpuscle:

Answer 37

touch receptor that detects transient pressure and higher frequency vibration

Question 38

Ruffini corpuscle:

Answer 38

touch receptor that detects stretch

Question 39

vestibular sense:

Answer 39

contributes to our ability to maintain balance and body posture

Question 40

Answer 40

responding to mechanical stimuli, such as stroking, stretching, or vibration of the skin
