response time Flashcards
reaction time
time taken between the onset of a stimulus to onset of a response
e.g time it takes hearing the gun to pushing off the blocks
movement time
time taken to complette a task
e.g time ebtweeen pushing off blocks to crossing finishing tape
repsonse tiem
time taken from the onset of a stimulus to the completed task
e.g time taken to hear gun and hitting the finishing tape
response time=movement time + reaction time
simple reaction time
one specific reponse to one stimulus
e.g hearing gun product fast reponse as only having to think about one thing
choice reaction time
choosing from numerious stimuli
response time is slower as more to think about
e.g in team games passing to right player
hicks law
reaction time increases as the number of choices increases
single channel hypothesis
only one stimulus can be processed at a time
second stimulus must wait until first has been processed
psychological refractory period
a delay caused by the second stimulus is presnted before the first has been processed
perfomer may freeze to sort out conflicting info
how can they use the delay(psychological refractory period) to their advnatge when playing sport
decieve their oppont to force a delay in their response
e.g performing a dummy pass in team game or using fake body langauge to fool opponent
anticipation
pre-judging a stimulus
wher perfomrer guesses what is going to happen before it happens
temporal anticipation
pre-judging WHEN a stimuli is goign to happen
spatial anticipation
pre-judging WHERE and WHAT the stimuli is going to be
correnct anticiaption imporves response time
what ways can a coach use to impprve performers response time
use mental practice. going over task in mind means the action be predicted and made quicker
train to the speciic stimulus in game
learn to focus and conectrate during the game. so that stimulus is picked up early
imporving fitness imporves reponse time
