Factors affecting response timeSlide2
Influences on reaction time
Experience
Experienced player will be able to
anticipateBe in position to hit an attacking shot in badmintonGet to a loose ball first in footballTypes of anticipationEffector anticipationA feel for the way the pitch plays (practicing on clay courts before French open)Perceptual anticipationGaining a prior knowledge of an opponent (watching a video of an opposing sides short corners)Receptor anticipationPicking up information during the game through changes in stance/grip (grip of cricket bowlers)Normal delivery In-swingerSlide3
Influences on reaction time
Stimulus intensity
Performers tend to react faster to something which is loud or bright.
Use of orange ball when snow covers football pitchGenderMen have faster reactions than women but lose them at a quicker rateAge reduces reaction times of both gendersFitnessReaction times will be quicker if a player has trained to improve their physical fitnessReduces response timePerformance enhancing drugsCan improve reaction timeFamous start by Ben Johnson at 1988 Seoul OlympicsSlide4
Stimuli are processed along a single nerveBrain can only process one stimulus at a timeStimuli must wait for the one before
it
can be dealt with
Think about cars waiting at a road junctionCauses a bottleneck at nerve Stimulus 1 Stimulus 2Single channel hypothesisSlide5
Psychological refractory period
Psychological refractory period (PRP) is based on single-channel
hypothesis
It suggests that, if a second stimulus is presented before first stimulus is processed then an unavoidable delay will occur.The delay occurs because the second stimulus must wait for the first to be processed even if it is no longer validBall clipping the net in tennis and changing directionBall deflected off a defender and past goalkeeper
A dummy pass in rugby
Trick plays in American footballPRP is used to create time for yourself to perform the skill you desire or to create space Present two stimuli in quick succession so there is no time to deal with first stimuli before second is presented
