1
Q

Define ‘response time’

A

= time taken from the onset of a stimulus to the completion of a task

reaction time + movement time

Q

What does a faster response time mean

A

faster repsonse = more time the player has to execute the skill

  • when skills are open/unpredictable, it is important to make decisions quickly
  • allows player to quickly adapt to changing situaitions

Q

define ‘reaction time’

A

= the time taken from the onset of the stimulus to the onset of a response
- no movement
- a fraction of a second

Q

What is ‘choice reaction time’?

A

= more than one stimulus to choose from, and maybe more than one repsonse to make
- slower response

Q

Give an emaple of hcoice reaction time

A
  • midfiled in hockey has lots of choices to make & needs to reposnd quickly
  • netball = lots of options to pass (who/how/where)

Q

Factors affecting reaction time.

A
  • age
  • gender
  • stimulus intensity (louder bang=faster reaction)
  • height (taller=slower reaction time)
  • arrousal levels
  • important cues
  • body language/position
  • anticipation

Q

Is the relationship between choices & reaction time linear?

A

the relationship is not linear, because players/opponents will get used to the options

Q

Explain the ‘single channel hypothesis’

A
  • stimuli can only be processed one at a time

2nd, 3rd, 4th … stimuli must wait

Q

What effect does the single channel hypothsis have on reponse time?

A

reponse time is increased, because the 2nd stimulus in delayed

Q

What is the pyschological refractory period?

A

= a delay when a 2nd stimulus is presented before the first has been processed

  • the lull time between finsihing processing stimulus 1, and processing/making a decision for stimulius 2

Q

Use a diagram to represnt psychological refractory period

A

S1———–|———–R1
S2————|————-R2
|———| = psychological
refractory period

17
Q

What could the perfromer do during the PRP?

A

A performer could freeze for a split second, becasue they need to sort out the conflicting information

18
Q

How can you use the PRP to your advantage?

A

You can use multiple stimuli agaisnt the opposition to dealy their response/increase their reaction time

e.g:
- fake/dummy pass
- fake body language (satdnign as if you would do a short serve in badminton, but hitting the shuttlecock long)
- clipping the net, so the ball bounces off in an unexpected direction

19
Q

Define ‘Anticipation’

A

= pre-judging a stimulus

20
Q

What are the 2 types of aniticipation?

A
  • spatial
  • temporal
21
Q

Define ‘spatial anticipation’

A

= where and what is going to happen

22
Q

Define ‘temporal anticipation’

A

= when it is going to happen

23
Q

What could correct anticicaption lead to?

A

if anticipation is correct, then repsonse time could be reduced

24
Q

Why does correct anticipation decrease reposne time?

A

The infromation processing process has sped up, then the information has been processed before the action has actually happened. So the movement aspect of the reposne can happen immediatly.

25
Q

What does incorrect anticipation cause?

A

Increased repsonse time

26
Q

Why does incorrect anticipation lead to increased reposne time?

A

If the stimulus presensted is NOT the one predicted by the perfromer, then there will be a delay whilst the actual stimulus is processed.
- this is because the actaul stimulus is acting as a 2nd stimulus, linkign to the single channel hypothesis &pschologuival refractory peirod

27
Q

How to improve anticipation

A

Experience
- allows perfromer to recognise stimuli/process information befroe the action occurs

28
Q

How can a perfromer prevent opponents from anticipating their actions?

A
  • being unpredictable
  • randomising actions
  • disguising actions
29
Q

What factors help a player with anticipating the action of their opponent?

A
  • infroamtion from environment
  • singals/cues from opponent
  • body language
  • sound/communication
  • position of opponent
30
Q

How can you improve response time?

A

1) mental practice
2) Training to specific stimuli
3) Learning to focus and concerntrate
4) Improving fitness
5) Anticipation

31
Q

Improving reposne time:
explain mental pracitce

A
  • going over the task in mind prior to the execution of actions
  • repsponse preperation time is improved
  • action can be predicted
  • closed and serail skills
32
Q

Improving reposne time:
explain training to specific stimuli

A
  • helps the memory system
33
Q

Improving reposne time:
explain focus and concerntraion

A
  • stimulus can be pciked up earlier
  • coaches can make stimuli more intense to enahcne concerntaion
34
Q

Improving reposne time:
explain improving fitness

A
  • imporves reaction time, speed & power
35
Q

Improving reposne time:
explain anticipation

A
  • helps predict the stimulus
    done correctly = decreased response time
    done incorrectly = increased rsponse time
