Sensory Processing and Perception

Question 1

Weber’s Law

Answer 1

pertains to the being able to detect a signal and the degree which you can recognize

Question 2

absolute threshold refers to

Answer 2

minimum need to stimulate a sensory neuron– signal enough to induce an action potential

Question 3

pathway of outer ear

Answer 3

pinna–> external auditory canal–>tympanic membrane–>ossicle–>membrane labyrinth

Question 4

pathway of middle ear

Answer 4

malleus–>incus–>stapes

Question 5

pathway of inner ear

Answer 5

eustachian tube–> bone labyrinth oval window–>perilymph–>basilar membrane–>round window–>vestibularocochlear

Question 6

sound is processed by the brain

Answer 6

vestibulocochlear–> medial genicular–> nuc (thalamus)—>auditory cortex–>superior olivary–>inferior colliculi

Question 7

what is the organ of corti

Answer 7

hearing apparatus that rests on the basilar membrane (endolymph and perilymph)

Question 8

Is the meissner corpuscle and merkel’s disk

Answer 8

somatosensory nerves that response to deep pressure and texture and vibrations

Question 9

auditory pathway for a prosthetic hearing system

Answer 9

organ of corti–>thalamus (medial geniculate nucleus)–>auditory cortex

Question 10

what is the purpose of the superior olives

Answer 10

determine sound localization (brain stem)

Question 11

what is the purpose of inferior colliculus

Answer 11

startle reflex as wekk as the vestibulo ocular reflex

Question 12

what is the function of rods and cones

Answer 12

cones– precision, detail and color
rods- black and white, and motion

Question 13

magnocellular vs parvocellular

Answer 13

neurons that help detect motion vs. neurons that help perceive shape and detail of stationary objects

Question 14

difference between monocular cues and binocular cues

Answer 14

monocular cues can be perceived with one eye

binocular cues are required with both eyes

Question 15

signal detection theory

Answer 15

predict when an how signals will be recognized ( hit miss rejection and false positive)

Question 16

sarif-whorf theory

Answer 16

those speaking different languages have different cognitive process (linguistic relativity)

Question 17

Gestalt’s Principle

Answer 17

similarity, continuation, closure, proximity, figure/ground, and symmetry & order

Question 18

figure-ground Gestalt’s Principle

Answer 18

see image as being in background or foreground

Question 19

sensory adaptation

Answer 19

change in sensitivity to the stimulus

Question 20

what is the network that extends through the brainstem that is responsible for alertness and awakeness

Answer 20

reticular formation

Question 21

focal point Gestalt’s Principle

Answer 21

items that are unique will standout first

Question 22

proximity Gestalt Principle

Answer 22

we perceive objects close together in groups
