Q

template theory

A
  • requires a huge number of templates to account for all variation
  • works well in constrained environments
  • calculates correlation between template and input

Q

search asymmetry

A
  • Easy to find a tilted line against vertical ones, harder to find a vertical line against tilted ones
  • Easy to find a vertical line against tilted ones
  • Tells us what the features are
  • Easier to find the “tilt” than the “not tilt” indication that a feature we use is “tilt” not “absence of tilt” (gap not absence of gap)

Q

structural theory

A

Our mental models of objects are made up of components called geons

17
Q

is it easier to identify objects when geons are intact or distrupted

A

intact

18
Q

geon distruption task

A
  • Every other edge or line is deleted to create complementary images (images contain different geons)
    You see complete geons essentially so can identify object faster
19
Q

are some things hard to distinguish based on geons?

A

yes

apple vs. orange

20
Q

are faces special?

A

probably
hollistic not feature processing
we are highly specialize

21
Q

support for faces being special

A

inverted faces

composite face effect

22
Q

opposite of prosopagnosia

A

super recognizers

23
Q

overall how do we recognize objects

A

features
templates
geons

24
Q

word recognition

A

example of object recognition

25
Q

how to study reading

A

reduce stimulus presentation effect

26
Q

what do they use to test reading

A

tachistoscope

27
Q

how to measure reading

A

recognition threshold (ms)
percentage recognized
word frequency

28
Q

repetition priming

A
  • viewing a word once greatly helps you read it the next time
  • priming is like a warm up for your brain
  • has a much bigger affect on low frequency words
29
Q

context effects

A

context helps us to recognize objects, and change what we perceive

30
Q

context effects bottom up processing

A

its not all putting features together

31
Q

context effects top down processing

A

context, knowledge about the world matters too

32
Q

word superiority effect

A

it is easier to perceive a letter when it is part of a word than when it is presented on its own

33
Q

is reading just putting individual letters together

A

no people are actually more accurate when the letter was presented in a whole world, than by itself

34
Q

reading error

A

tend to misread less common sequences as more common one (over-regularization)

35
Q

feature net

A

each detector has its own baseline activation level (resting level)

36
Q

word frequency

A

higher frequency words are recognized faster (higher baseline levels)

37
Q

repetition priming

A
  • The current activation level of a word node is still active above baseline when the corresponding stimulus word is repeated hence it takes relatively less additional activation energy and less time for this word node to reach threshold the second times
  • Baseline itself may be affected only after LOTS of encounters
38
Q

well-formedness

A

faster to read well formed strings

39
Q

recover from errors in sensory and perceptual processing

A

The same mechanisms that lead to misperceptions, also allows us to recover from errors in sensory and perceptual processing

40
Q

robust pattern recognition

A

mechanisms help to explain the word superiority effect as well

41
Q

proofreading

A 
writing primes you
read slow
read backwards
take a break from paper
input misperceived
