Response, reaction and movement time

Cards (9)

  • Reaction Time definition
    The time from the stimulus to the initiation of response
  • Movement Time definition
    From the initiation of the response to the completion of the action
  • Response Time Definition
    Time from the stimulus detection to the completion of the movement
  • Response Time Equation
    Reaction Time + Movement Time = Response Time
  • Hick's Law
    • The more choices the athlete has, the more information that needs processing, the longer it takes to process the information, so the slower the reaction time, thus slower response time
    • Athletes with more info struggle with selective attention
  • PRP
    • Psychological Refractory Period
    • Refers to the period of time during which the response to a 2nd stimulus is significantly slowed because a 1st stimulus is still being processed
    • Is a 0.2-0.3 second delay
  • PRP's affect on reaction/response time
    • Reaction is slowed down because the 1st stimulus having to be cleared before the 2nd can be processed
    • If a performer can fake a movement, the opponent will be unable to clear the 1st stimulus in time
  • Feedback is most effective when: ACE IT
    • Accurate
    • Concise
    • Easily understood
    • Immediate
    • Truthful
  • How to improve/reduce reaction time
    • Regular practise
    • Intensity stimulus
    • Verbal cues
