1

amblyopia

loss of visual abilities in a weaker eye

2

Strabismus

lack of coordination of movement in both eyes

3

kinesthetic sense

receptor cells in muscles tell us if we are moving and in what direction

4

vestibular sense

located in the semicircular canals of the ear telling body position

5

3 gestalt grouping laws

proximity, closure, and similarity

6

What is depth perception

relies on two types: binocular and monocular

7

what is convergence

a binocular cue that is the tendency of the eyes to move toward each other as we focus on an object up close

8

binocular disparity

different images of objects are cast on the retinas of each eye

9

monocular cues

cues from one eye, 2 dimensional

10

gestalt principles are by what process?

top down

11

visual agnosia

damage to the what pathway

12

prosopagnosia

form of visual agnosia in which people cannot recognize faces

13

vision path in the brain

visual info leaves retina, travels to superior colliculus to thalamus to primary visual cortex in the occipital lobe

14

opponent process theory suggests and explains what

colours are processed in opposite pairs and explain after images. If you stare at green too long you can't see red

15

What three structures analyze colour in antagonistic opponent pairs?

ganglion cells, thalamus and visual cortex

16

What does trichromatic theory suggest

there are three different sensors for colour and each type responds to a different wave length

17

what is electromagnetic radiation?

a stimulus for light

18

what is tinnitus

ringing in the ear

19

What is amusia

tone deafness, inability to distinguish between pitch

20

path of hearing in the brain

cochlea to brainstem to thalamus to auditory cortex to auditory associated areas in the cortex

21

3 ways we adapt to noise

muscle contractions, hair cells becoming less sensitive and attention (cocktail party effect)

22

two major causes of deafness

conductive (blockage or break in hearing process) or nerve (damage or malformation of hair cells or auditory nerve)

23

frequency

pitch of sound

24

amplitude

loudness

25

familial dysaitonomia

inability to detect pain or temperature

26

endorphins and enkephalins are

natural pain killers

27

cingulotomy

destruction of the cingulate cortex

28

gate control theory

patterns of neural activity can actually close a gate that prevents messages from reaching parts of the brain where they are perceived as pain

29

anosmia

inability to smell

30

ageusia

inability to taste
