Response time Flashcards
Reaction time
Time taken from onset of a stimulus to the onset of a response
Movement time
Time taken to complete a task
Response time
The time taken from the onset of stimulation to the completion of the task
Response time equation
Reaction time + Movement time
Simple reaction time
One specific response to a specific stimulus
Fast reaction time as only 1 stimulus to process
(Gun shot)
Choice Reaction time
Choosing from lots of stimuli takes longer so response slower
In team games, play may need to choose a number of responses once correct stimulus chosen
Hicks Law
Reaction time increases as number of choices increase
Can be used to advantage to keep opposition guessing
Reaction time will decrease as player becomes familiar with environment so rate is non linear
Single channel hypothesis
Stimuli can only be processed one at a time
Any further stimuli must wait until the first has been processed
Delaying in processing helps explain hicks law
Psychological Refractory Period
A delay when a second stimulus is presented before the first has been processed
Performer may appear to freeze for a split second to sort out conflicting info
Can be used to advantage - fake pass
Anticipation
When a performer tries to pre judge a stimulus
Predict what is going to happen
Use body language cues
Can be found out by researching opposition
Types of anticipation and their difference
Temporal - Pre judging WHEN stimulus occurs
Spatial - Pre judging WHERE stimulus will occur and WHAT it is
Can improve response time
Info processed before movement happens
Improving response time methods
Mental practise
Train specific stimulus
Learn to focus to anticipate stimulus - make stimulus intense
Improve fitness - plyometric for power, interval for speed
