Decision making and Response time Flashcards
1
Q
What is the response selection stage?
A
- deciding how to respond
- need to decide what movement to make
- ball coming towards me…should i catch it? if so how?
2
Q
What is the translation process?
A
- decision making
- until one stimulus has had a decision made about it, another cannot be acted upon (SCH)
- decision making can be improved by: practice, highlighting relevant cues
3
Q
Reaction time
A
- it’s genetically determined and influenced by the uncertainty of stimulus to performer
- refers to time taken to make a decision
4
Q
Movement time
A
- time taken from when movement is initiated to the point when movement is complete
- determined by muscle fibre type, level of learning of motor programme involved
5
Q
Response time
A
- time from stimulus being given to the end of the result
- Response time = reaction time + movement time
6
Q
What are the 2 types of reaction time?
A
- Simple RT: one stimulus w/ only one correct response -> e.g. reacting to starting gun by running down the track towards finish line
- Choice RT: several stimuli, which may have a number of responses or one stimulus w/ a number of responses
7
Q
What affects reaction time?
A
- age/gender
- fatigue
- intensity of stimulus
- probability of stimulus occuring
- presence of warning signal
- intensity of warning signal
- temperature
- previous experience
- body size
- anticipation
8
Q
Hicks Law on choice reaction time
A
- “cjpoce reaction time is related to the amount of info that must be procesed to resolve uncertainty about various possible stimuli response alternatives”
9
Q
What can players do to improve RT?
A
- concentrate on cue/selective attention
- relevant practice
- optimum arousal levels
- anticipation
- mental rehearsal
- improve movement time/fitness
- increase intensity of stimulus
