Attention and Performance Flashcards

1
Q

What is attention?

A

1) An ability - focus on one of many incoming stimuli
2) Intentional - done on purpose and controlled
3) Is limited - attend to one thing means you lack attention to everything else

A

Lose information along the way

Countless stimuli enter in parallel

A

actions are emitted in serial fashion (3/sec)

Q

Why do we need attention?

A

Because we receive about 45GB of info/ sec

Need to filter out useless information and focus on what is relevant

Q

What is the stroop effect?

A

Competition between the response to the colour word and the ink colour
-shows parallel processing and that streams compete

Q

What is the cocktail party effect?

A

Engrossed in one conversation in a noisy environment but automatically hear your name
-Shows parallel processing and that streams of info are being processed without explicit attention

Q

What is inattention blindness?

A

When our attention is absorbed by one stimulus stream and as a result we are “blind” to other info

Q

What is sustained attention?

A

After a period of time the task of concentrating on a single target of our attention becomes a progressively more difficult chore

Q

What are the limits in response selection?

A

It is difficult to perform two very different tasks at the same time
Depends on whether the tasks are controlled or automatic

Q

Why do fakes work?

A

One person chooses to initiate
The other has to identify an react- when the programming is wrong there is interference when you try to stop and start another action.

Q

What are the limits of movement?

A

Not a limit of identification
Not a limit of selection
But a limit of programming

16
Q

What is psychological refractory period (PRP)?

A

The delay in responding to a second of two closely spaced stimuli

17
Q

What is the double stimulation paradigm?

A

Interested in the stimulus onset asynchrony
Once you have started the programming response to the first stimulus you cannot program a response to the second stimuli that is greater than 100ms later.

18
Q

What is grouping when talking about the double stimulation paradigm?

A

Both stimuli detected as a single event and organize a single, more complicated action

19
Q

Testing the psychological refractory period (PRP)

A

Response is slowest to probes close to movement onset
Response also slows close to end of movement
Response to probe slowed down by any movement, more by small target movements

20
Q

What are conclusions about the PRP?

A

Action demands attention
Different actions demand different amounts of attention
Some phases of action demand more attention than other phases

21
Q

Where to focus attention during programming?

A

Internal focus: Own moving body and execution of movements

External focus: on external target like specific target of movement

22
Q

What is arousal?

A

The level of activation of the central nervous system

23
Q

What is anxiety?

A

Uneasiness or distress about future uncertainties; a perception of threat

24
Q

What is the inverted U-principle?

A

The relationship of arousal and anxiety effecting performance

25
Q

What is the “zone”

A

The region of arousal that give optimal performance

26
Q

What happens if you have high-trait-anxiety?

A

You perform better under low arousal

27
Q

What is narrow range of optimality?

A

When you have a small range when you perform the best

28
Q

How are fine motor skills effected?

A

Perform better with low arousal

29
Q

How are gross motor skills effected?

A

Performance is better with higher arousal

30
Q

What is perceptual narrowing?

A

The narrowing of attentional focus as arousal goes up

31
Q

What is cue-utilization hypothesis?

A

Explanation of low/high arousal effects on performance

32
Q

What happens with a wide perceptual field?

A

Process lots of stimuli but not in great detail

33
Q

What happens with narrow perceptual field?

A

Can be inefficient because each stimuli get processed too much

34
Q

What does it mean to choke?

A

When performers change their normal routine or fail to adapt to changing situation resulting in failed performance
