Q

describe the idea of attention being a pool

A

attention is like a the water in a pool
1. the way the attentional resources (water) are allocated define how we use attention
2. that water is limited
-to get water back must stop doing a task or get more efficient at it

Q

what is the stroop effect and give an example and why

A

illustrates how the atuomaticity of reading can interfere with our perfance
-difficulty naming a physical colour when it is used to spell the name of another colour
-process both colour and writing letters in parallel which creates conflict when it comes to response selection

Q

what is the cocktail party effect in this class

A

if you are having your own conversation and there is a seperate convo going on near you, you are able to focus on what the people you are talking to are saying and ignore what others are saying
-however, if you hear a word in relavince to you, for example your own name, it will catch your attention
-even though not consciously listening, if someone says something relevant to you, you hear it (procces info in parallel)

Q

when is interence between tasks the most obvious and what stage of the informatino process does this happen in

A

when performaer must perform 2 actions simultaneously
-response selection cause they require that hcoices be made among several possible alternative responses

25
automatice info processing is thought to be the result of what
an enormous amount of rpactice
26
what is the benefit of automaticity
processing info in parallel, quickly, and without interference from other processing tasks -ability to attend to other aspects of performance -effective when environement is stable and predictable (closed skills)
27
What is a disadvantage of automaticity
will perform the expected movement when it may not always be the best choice -not effective when environment changes often (open skill) -so many more patterns are possible - would have to develop automatic response to all of them (possible but with practice)
28
when is automaticity most effective
in closed skills where envionrment is mostly predictable
29
what is the double stimulation paradigm give example
subject is required to respond with separate responses to each of 2 stimuli presented very closely in time -respond to a tone by lifting right hand -very short time following the tone -light appears, and respond by lifting left hand
30
what is stimulus onset asynchrony
duration of between the 2 stimuli in a double stimulation paradigm
31
what is the single channel hypothesis
argues that processing of a first stimulus and response completely blocks the processing of a second stimulus and response until such time that the processing of the first response and stimulus has been completed
32
what are you looking for whne using a double stimulus paradigm
interested in how long it takes to respond to second stimulus
33
in the double sitmulation paradigm, there is usually a delay to the response of the second stimuli becuase of what
due to interference with movement programming -single channel hypothesis
34
what is critical in psychological refractory period and why
stimulus onset asynchrony -it determines if and how long response will be delayed
35
when does grouping of 2 sitmuli happen and what is it
when 2 stimuli appear really close together in time - 30-40ms of stimulus onset asynchrony -processing them as if they were one
36
what is psychological refractory period
delay in responding to the second of 2 closely spaced stimuli
37
what is the bottleneck theory
processing that happens during movement/response programming -can only organize and initiate one action at a time -any other action must wait until stage has finished initiating
37
what type of processing happens at each stage of information processing
stimlus identificaiton -lots of parallel processing response selection -mix of automatic and controlled processing response programming: cereal processing
38
what is an explanation for the psychological refractory period
the bottleneck theory in response programming stage
39
when is the bottleneck theory delay the largest and why
when the time between stimuli (stimulus onset asynchrony) is short -at this time, the mvoement must be emitted before the stage can begin to generate second response
40
what happens when the stimulus onset asynchrony is very short, say less than 40ms
grouping -motor system responds to second stimulus in a very different way
41
what are 2 methods that can be used for studying how attention demanding a task is
-double stimulus paradigm -probe task
42
what does the probe task inlcude and describe how it would go
primary task and secondary task -while subject performs primary task, researcher would probe hte attention demanded in this main task by presenting a secondary task -subject must respond to this task as rapidly as possible, either manually or vocally -RT would measure the delay in responding to the probe
43
when using the probe task technique the researcher would use the RT to the probe as a measure of what
the attention demanded by the primary task
44
in the probe task, the more attention demanding the primary task is, this would result in what type of response to the probe
slower
45
in probe task technique, the secondary task is usually what type of stimulus
discrete
46
what is the problem for probe techniques when it comes to responding manually to the probe
this can produce specific interference effects with a manual primary task -nature of the reposnse to probe was incompatible with movement require for primary taks -attention demands assessed by delay in probe RT contaminated by compition between movement requirements
47
when is there less competition between movement requirements
when responses require movement from things that are not associated with each other, for ecample moving limbs and making noise
48
what is internal focus of attention
focusing on our body movements
49
what is external focus of attention
focusing on result or goal of our actions
50
when does choking occur
when performers change their normal routine, or fail to adapt to a changing situaiton and fail in their performance -using pathways havent practiced using yet
51
in almost all situations, what results in more skilled performance, external or internal focus of attention
external
52
cell phone law is very based on what view of attention
output modality -cant do 2 thigns at once if require same output modality -for example, cant look at phone while driving cause need to look at road -but can talk on phone while driving
53
what is the problem with the cellphone law
elements of response selection and programming regardless of whether using different ouput modalities require our attentional resources -response seleciton will be delayed even without a structural interference
54
what is the inverted u principle
represents an early view of the relatioship between arousal and performance -increasing arousla level generally inhances performance, but only to a certain point until it -quality peaks at some intermediate value of arousal
55
what is the idea behind the updated inverted u
takes into account that the relationship between arousal levels and performance is not that straight forward -different people performa better under higher or lower amounts of stress -depends on individual an dtask
56
whats another word for tunnel vision
perceptual narrowing
57
what does tunnel vision allow
the performer to devote more attention to those stimuli that are immediately most lilkely and relevant
58
tunnel visino can be responsible for what
inattention blindness -so focused on one thing you miss other things around you
59
which stages does the hands free law of driving believe is affected
response programming
60
explain the study we talked about in class about novel warning systems and what were the results
STUDY -2 types of warning sytems: tactile from seat belt and auditory from speakers -9 conditions : none, simple and complex convo with either no warning, tactile or auditory RESULTS -Tactile RT faster then no warning signal -auditory RT no better than no warning
61
physiologically, the results of the study about novel warning systems makes sense how
both visual and auditory info must go through cortex in order for us to respond -tacticle info can mae use of networks and responses before it travels to cortex (faster route)
62
based on the experiment we talked about in class about novel warning signals, complex conversations always caused RT to be what
increased
