Q

What are the 3 ways behaviorism lost its hold on psychology?

A
  1. “cognitive maps” rather than learned sequences
    - ex. coming up with different routes even if you’ve never used them
  2. Verbal behavior
    - kids say things they’ve never heard, use incorrect grammar
  3. Misbehavior of Organisms
    - behavior reflects evolution, not simply learning or reinforcement

31
Q

A

false

32
Q

T/F:

cognition uses only top-down processes

A

false- uses both top-down and bottom-up processes

33
Q

What are the two theories for object and pattern recognition?

A

template matching model, feature analysis theory,

34
Q

What is the template matching model?

A

Claims a stimulus must be compared with a set of specific patterns (templates in memory) - like a stencil, miniature copies

35
Q

What are the problems with template matching model?

A 
size matching
orientation matching (alignment)
configuration matching
memory load (huge # of templates required)
incomplete figures
36
Q

What are the 4 steps of the feature analysis theory?

A
  1. register sensory input
  2. detect features
  3. compare detected features to stored info (memory)
  4. decide on best match
37
Q

What is evidence for feature analysis theory?

A

letters have distinctive features
confusion errors - C vs. G vs. H
“feature detectors” in visual cortex - cells that respond most strongly to one feature
results of some visual search tasks - like trying to find your car in the parking lot

38
Q

What are some problems with feature analysis theory?

A
  1. strictly bottom-up theory, but top-down is important

2. global (Gestalt) effects - not holistic, don’t involve detection of pieces

39
Q

What are complexity effects?

A

when we make features more complex and the task gets easier

40
Q

What is the word superiority effect?

A

letters are identified more quickly and accurately when they appear as part of a word

41
Q

What are context effects?

A

you will categorize things differently based on context alone, not features
ex. A 13 C, 12 13 14

42
Q

What is a perceptual set?

A

a readiness to perceive things in a certain way, usually due to expectations
ex. pictures of animals > rat
pictures of heads > man

43
Q

What is subjective contour?

A

illusory contour - background color/lighting makes you see different images

44
Q

What three words could be used to describe attention?

A

conscious, selective, limited

45
Q

What are the three benefits of attention?

A

accuracy, speed, memory

46
Q

What gets your attention?

A

Goal-directed selection

Stimulus-driven capture

47
Q

What is goal-directed selection?

- what type of processing does it take?

A

top-down processing, intentionally deploy attention to specific objects or spatial regions

  • voluntary and requires effort
  • can have long duration, required for vigilance (sustained attention in monitoring low-frequency events)
  • featural distinctiveness: easier if something sticks out
48
Q

What is stimulus-driven capture?

A

bottom-up “surprise”

  • involuntary, rapid response
  • quickly dissapates
  • abrupt onset
  • change
49
Q

What is the “Cocktail-party phenomenon?”

A

we have the ability to selectively attend one conversation, but not to several at once

50
Q

Dichotic Listening Technique

A

came from people listening to 1 story while reading another do not comprehend both

51
Q

What is shadowing?

A

repeating message immediately and accurately

52
Q

What are the + and - of attended (shadowed) message?

A

+ often easy to shadow one message

- couldn’t follow 1 of 2messages presented to the same ear unless presented with the same voice and loudness

53
Q

What are the + and - of unattended (unshadowed) message?

A
  • could report almost nothing about ‘rejected’ message
    + could notice if sex of speaker was changed or if voice was replaced by a tone in the middle
  • didn’t notice language changes like English to German
    + often notice their name in unattended message (we can notice physical properties, but not meaning
54
Q

What are the theories of selective attention?

A
  1. Filter (bottleneck)
  2. Neisser’s 2-stage model
  3. Feature integration
55
Q

What is the Filter (bottleneck) theory of attention?

A

assume limited capacity ‘CPU’ - one process at a time

- sensory inputs are selected on basis of physical properties (loudness, pitch)

56
Q

What are the problems with the filter theory of attention?

A
  1. how do we switch “channels” if we’re unaware of the content (meaning) of unattended inputs (how do we hear our name in unattended conversation)
  2. words in unattended messages can intrude on shadowed message if they fit (left and right ear different sentences)
57
Q

What is Neisser’s 2 stage model of attention?

A

proposed that attention/perception involved both

  • preattentive (rapid & parallel) processes
  • attentive (controlled & serial) processes
58
Q

What is the feature integration theory?

A

Triesman - current theory of attention and pattern recognition that involves 2 successive processes

  • feature detection
  • focused attention (feature integration)
59
Q

(Feature Integration Theory)

What is feature detection?

A

“distributed attention”

  • automatic and rapid parallel process of detecting features (breaking it down into parts)
  • certain features are more salient than others (color; orientation)
  • supports “global attention” - can segregate scenes into discrete areas, select targets for later ID, and monitor for salient and unexpected events
    ex. go to supermarket for avocado, search for avocado-like features
60
Q

(Feature Integration Theory)

What is Focused Attention?

A

Feature integration

  • required to identify objects and correctly detect combos of features
  • requires serial processing and time
  • can be influences by stored knowledge (ex bananas are yellow)
    ex. put together which features go with which (avocados are green and round)
61
Q

What evidence supports the Feature Integration Theory?

A
  1. pop-out research: targets that differ from surrounding distractors by a single dimension are spotted effortlessly and detection time does not depend on # of distractors
    - ex. at a football game see someone on away side wearing orange
  2. illusory conjunction - “binding problem,” insufficient attention
    - incorrect impression about features that go together
    ex. seeing what you expect to see, fruit: red banana, yellow apple - will report normal color
62
Q

What is inattentional blindness?

A

unattended events/objects are not consciously registered

  • often go unnoticed
    ex. gorilla basketball video
63
Q

What is change blindness?

A
  • brief blanks cannot be seen
  • gradual change often missed (ex. rock appearing in scenery video)
  • “lost” person asks for directions, helper staring at map doesn’t notice when “lost” person switches
64
Q

What is attentional blink?

A

when 2 targets are presented in rapid sequence, later target is often missed

65
Q

What is mindless reading

A

Reading without attention

66
Q

What is divided attention and dual-task performance?

- what are the effects

A

We think we can multitask, but we can’t

  • pseudo-multitasking
  • performance decrements noticed on both tasks
  • insufficient practice
67
Q

Many well-practiced skills are ___ - seem to require no effort or attention

A

automatic

Ex. reading

68
Q

What are the three main factors that affect dual-task performance?

A
  1. practice
  2. task similarity
  3. task difficulty
69
Q

What is the cognitive unconscious?

A

some cognition occurs without conscious awareness

70
Q

What is blindsight? (cognitive unconscious)

A

vision without awareness

  • patients w/brain damage couldn’t see part or all of visual field, yet they are able to respond appropriately
  • can answer questions about what’s in front of them
71
Q

What are “automatic” processes?

A

ex. driving a long way but not realizing where you’ve gone/what you’ve seen

72
Q

What is subliminal perception?

A

behavior and physio responses can be influence by stimuli below threshold of awareness
ex. movie theaters slipping in clip of popcorn

73
Q

What are four responses of subliminal perception?

A
  • responses in dichotic listening tasks - bank interpreted as river or money depending on ear
  • very brief of low intensity stimuli, or masked stimuli can have effects
  • effects seem limited to weak but significant changes in arousal, positive or negative affect and other non-specific responses
  • subliminal perception of complex messages ex rock music
