hits the temporal hemiretina of the right eye but the nasal hemiretina of the left

Q

each spot in the visual cortext

A

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

Q

retinal disparity

A

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

Q

3D glasses, VR

A

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

Q

vergence

A

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

Q

monocular cues

A

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

Q

bottom up processing

A

data driven
using incoming information to drive perception

20
Q

top down processing

A

conceptually driven
using our knowledge or experience to drive perception

21
Q

auditory stimulit

A

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

22
Q

ambiguous images/bistable images

A

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

23
Q

controlled processes

A

require attention

24
Q

automatic processes

A

don’t require attention

25
Q

reading vs constructing ideas

A

automatic vs controlled processing

26
Q

feature integration theory

A

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

27
Q

automatic processes vs reflexes

A

used to require effort but now can do without really thinking

28
Q

advantages of automaticity

A

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

29
Q

disadvantages of automaticity

A

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

30
Q

dichotic listening

A

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

31
Q

people notice

A

change voice male to female
change from forward to backwards

32
Q

people didn’t notice

A

english to german
any of the content

33
Q

Broadbent’s filter theory

A

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

34
Q
A
35
Q

priming

A

already thinking down a certain path

36
Q

MacKay

A

subliminal perception: memory being influenced without their awareness

37
Q

Deutsch & Deutsch Late selection model

A

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

38
Q

early selection

A

filter stuff out fast

39
Q

load theory

A

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

40
Q

primary task demanding

A

no resources left to do anything else
early selection
no distraction

41
Q

primary task easy

A

leftover capacity
late selection
distraction

42
Q

K or N

A

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

43
Q

high load

A

no capacity for distractions, early selection

44
Q

low load

A

excess capacity for distraction, late selection

45
Q

ADHD

A

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
