Week 5

Question 1

left and right of the fovea

Answer 1

left - left visual field
right - right visual field

Question 2

outside of the eyeballs near the temples

Answer 2

temporal hemiretina

Question 3

inner edge close to nose

Answer 3

nasal hemiretina

Question 4

any object on the left

Answer 4

hits the temporal hemiretina of the right eye but the nasal hemiretina of the left
opposite occurs for the right

Question 5

lateral geniculate nucleus (LGN)

Answer 5

bundle of nerves in thalamus

Question 6

thalamus

Answer 6

place where all the info coming in goes first, before being sent out

Question 7

left side of space

Answer 7

goes to the right side & vice versea

Question 8

each spot in the visual cortext

Answer 8

corresponds to different areas of the retina, corresponds to different areas in space
different cells in visual cortex correspond with different areas of space

Question 9

corpus callosum

Answer 9

hemispheres connected by band of fibres
looks white cause there’s lots of myelinated axons

Question 10

hemispheres

Answer 10

process info in slightly different ways

Question 11

two ways of seeing depth

Answer 11

biocular cues - rely on both eyes
monocular cues - rely on only one eye

Question 12

retinal disparity

Answer 12

used to work out whether something is further or closer than disparity
perceived depth increases with increasing disparity

Question 13

uncrossed disparity

Answer 13

object farther than fixation

Question 14

crossed disparity

Answer 14

object closer than fixation

Question 15

3D glasses, VR

Answer 15

one version goes to the left, one to the right, you get disparity, brain treats it as depth

Question 16

vergence

Answer 16

another bionuclar cue
closer to the eye & vergence grows, you can use it to work out how far away something was

Question 17

monocular cues

Answer 17

eg art - flat surface, still feel depth
linear perspective
relative height and relative size
texture gradient
aerial perspective
interposition/occlusion
light/shade/shadow

Question 18

motion parallax

Answer 18

everything behind a point we’ve on will feel like it’s moving with us

Question 19

bottom up processing

Answer 19

data driven
using incoming information to drive perception

Question 20

top down processing

Answer 20

conceptually driven
using our knowledge or experience to drive perception

Question 21

auditory stimulit

Answer 21

misheard song lyrics
uses top down processing to try and work out what they’re saying

Question 22

ambiguous images/bistable images

Answer 22

one or another - not both
one version of reality at a time
have more than one perceptual interpretation

Question 23

controlled processes

Answer 23

require attention

Question 24

automatic processes

Answer 24

don’t require attention

Question 25

reading vs constructing ideas

Answer 25

automatic vs controlled processing

Question 26

feature integration theory

Answer 26

attention is necessary so that we can find the features of our world

Question 27

automatic processes vs reflexes

Answer 27

used to require effort but now can do without really thinking

Question 28

advantages of automaticity

Answer 28

long retentive tasks, streamlining, less effort, dual tasking, efficient, survival

Question 29

disadvantages of automaticity

Answer 29

bad habits, lack of control, outside awareness, error-prone, dangerous if not appropriate

Question 30

dichotic listening

Answer 30

one voice in one ear, one voice in the other - try to 'shadow it'/repreat it back

Question 31

people notice

Answer 31

change voice male to female change from forward to backwards

Question 32

people didn't notice

Answer 32

english to german any of the content

Question 33

Broadbent's filter theory

Answer 33

attention narrows the flow of information into awareness based on physical characteristics

Question 35

priming

Answer 35

already thinking down a certain path

Question 36

MacKay

Answer 36

subliminal perception: memory being influenced without their awareness

Question 37

Deutsch & Deutsch Late selection model

Answer 37

we process everything for meaning but only selected information makes it into our awareness

Question 38

early selection

Answer 38

filter stuff out fast

Question 39

load theory

Answer 39

attention is a flexible pool of resources low vs high perceptual load

Question 40

primary task demanding

Answer 40

no resources left to do anything else early selection no distraction

Question 41

primary task easy

Answer 41

leftover capacity late selection distraction

Question 42

K or N

Answer 42

low perceptual load & high perceptual load condition with distractor and no distractor

Question 43

high load

Answer 43

no capacity for distractions, early selection

Question 44

low load

Answer 44

excess capacity for distraction, late selection

Question 45

ADHD

Answer 45

tradeoff between things that break through and how much attention you allocate for things high or low - hyper vigilance, not processing anything else - top-down attention Or everything is competing
