22
Q

how does the cocktail party phenomenon occur ?

A

It is thought to occur because the brain has the ability to identify the spatial location of a sound and use that information to selectively attend to one particular auditory stimulus while filtering out other stimuli.

27
Q

how do the early and late theory differ ?

A

differs in the sense that it proposes that the filter or the the bottleneck occurs between stimulus identification and response selection

28
Q

what does bottleneck theory suggest ?

A

that individuals have a limited amount of attentional resources that they can use at one time

29
Q

what does PRP stand for?

A

psychological refractory period

30
Q

what is PRP?

A

refers to a delay in responding to the second of two closely spaced stimuli, when they are presented in rapid succession

31
Q

when does a PRP occur ?

A

this delay occurs because the brain is still processing the first stimulus, and it cannot fully process the second stimulus until it has completed processing the first one

32
Q

what happens in the attention as a single resource : psychological refractory period ?

A
  • delay in responding to the second of two stimuli presented in rapid succession
  • interference in selection and organization of response
33
Q

how do both stimulus’s move during the PRP attention as a single resource ?

A
  • stimulus 1 can get in
  • delay in second response
  • number 1 to go through first
34
Q

what experiment is done in regards to attention and automaticity ?

A

“putting practice to the test” (Leavitt, 1979)

35
Q

what happens during the “attention and automaticity” experiment by Leavitt ?

A

six age groups (6, 8, 10, 11, 14, 19) performing in each of four experimental conditions :
- skating only
- skating and geometric figures
- skating and stickhandling
- skating, stick handing and geometric figures

36
Q

what is a goal of the “attention and automaticity” experiment by Leavitt ?

A

to become essentially autonomic in the primary component before introducing the secondary component

37
Q

during the “attention and automaticity” experiment by Leavitt what time leads to better results ?

A

shortest time = better results

38
Q

during the “attention and automaticity” experiment by Leavitt, what are the age groups and their skill set ?

A
  • 6 to 8 = house league players
  • 10, 11 to 14 = rep players
  • 19 = OHL players
39
Q

in regards to attention and coordination what are the two phases ?

A

inphase and antiphase

40
Q

what is antiphse ?

A

refers to a particular type of coordination between two or more rhythmic movements or stimuli, in which the movements are timed such that when one is at its peak, the other is at its trough, and vice versa

41
Q

what is inphase?

A

refers to a particular type of coordination between two or more rhythmic movements or stimuli, in which the movements are timed such that they reach their peaks and troughs at the same time.

42
Q

what is studied during attention and ‘slips’ of attention ?

A

biased-competition models of attention

43
Q

what is the biased-competition models of attention?

A

seeks to explain how attention operates in the brain

44
Q

how does the biased-competition models of attention work ?

A

the model proposes that attention is a mechanism by which different sensory inputs or cognitive processes compete for representation in the brain, and that this competition is biased towards the most relevant or salient stimuli

45
Q

what are congruent global and local properties?

A
  • this paradigm focuses on using stimuli that have global and local properties that are either congruent or incongruent
46
Q

what are congruent global properties ?

A

refer to the overall shape or structure of a visual stimulus

47
Q

what are congruent local properties ?

A

refer to the individual parts or components of the stimulus.

48
Q

what is the stimulus that participants are faced with in the congruent global/local properties ?

A

stimulus = large “H” made up f a bunch of small H’s (in this ex, both global and local properties are H)

49
Q

when is a stimulus incongruent ?

A

when the global and local are different letters (a.k.a greater risk for increased number of errors)

50
Q

what type of stimulus’s do individuals take longer to identify?

A

local features for a stimulus that has incongruent global/local features

51
Q

what did Weismann et al look at ?

A

neural correlated of slips of attention

52
Q

describe what neural correlates of attentional slips mean ?

A

certain regions of the brain can tune or change the level of activity associated with sensory processing regions

53
Q

which region of the brain has more effect in regards to fine tuning and changing the level of activity associated with sensory processing regions ?

A

frontal region

54
Q

what was the particular task that Weismann et al were interested in ?

A

congruent local and global properties

55
Q

what are the three areas of reduced activation in neural correlated of attentional slips ?

A
  • inferior frontal gyrus (IFG)
  • middle frontal gyrus (MFG)
  • anterior cingulate cortex (ACC)
56
Q

describe the (IFG) in regards to neural correlated of attentional slips :

A

stimulus-triggered orientation of attention

57
Q

describe the (MFG) in regards to neural correlated of attentional slips :

A

maintaining task goals in working memory

58
Q

describe the (ACC) in regards to neural correlated of attentional slips :

A

conflict monitoring/resolution

59
Q

can you have attention without awareness ?

A

yes

60
Q

what did Ulric Neisser do ?

A
  • presented a series of 100 words
  • saw it 100x
  • 30 words has a shock associated
  • participants came back 6 months later
  • saw the sam words without the shock
  • was measuring galvanic skin response
  • words associated with shock led to increase galvanic skin response
  • demonstrated that consciousness doesn’t always need to be present
61
Q

what is galvanic skin response ?

A

measure of arousal

62
Q

what are the three default attention networks ?

A
  • posterior cingulate cortex
  • precuneus
  • middle temporal gyrus
63
Q

what does DAN stand for ?

A

default attentional network

64
Q

what does ST stand for ?

A

stimulus triggered

65
Q

which particular trials is it that are associated with reduced activity of 3 very specific regions of the brain ?

A

trials with very long reaction times
