Reaction Time and Effectiveness

Reaction Time
1. This is the time from the stimulus occurring to the performer starting to move in response to it
Movement Time
1. This is the time taken from starting the movement to completing it
Response Time
1. This is the time from the stimulus occurring to the completion of the movement
Factors Affecting Reaction Time
1. Sensory System receiving the system
  1. Type of sense being used
2. Body Temperature
  1. If we're cold reaction will be slower
3. Personality
4. Gender
  1. Males have quicker reaction times
5. Age
  1. Reaction time gets quicker until around 20ish
6. Levels of Alertness/ Arousal/ Motivation
  1. Optimum levels are needed to react quicker
Single Channel Hypothesis ^
1. Choice Reaction Time !
  1. Occurs when there is more that one stimuli and/or more than one response. Occurs in many supporting situation
2. Theory states that when we receive many stimuli from the environment, the brain can only deal with one stimuli at a time.This one piece has to be dealt with before the next piece can be dealt with
Factors Affecting Response Time
1. Levels of Arousal/ Motivation
  1. Coach has to ensure the performer is at the appropriate level of arousal/motivation for the activity
2. Practice
  1. The more often the stimulus is responded to the shorter the reaction time becomes If enough practice has been done the response will become automatic and require little attention
3. Experience
  1. Enhances awareness of a particular stimuli occurring
4. Stimulus-Response compatibility
  1. If you're normally make the same response it will be quicker
5. Warm Up
  1. Ensuring the cardio-respiratory, vascular and neurotransmitter systems are adequately prepared
6. Cue detection
  1. Analysing the opponents play to anticipate what they are going to do
7. Concentration
  1. Simple reaction only focus on 1 stimuli
Hicks Law
1. Important implications in what we always try to:
  1. Disguise our intentions and therefore increase the number of possible alterations that our opponents will have to select from. This will inc. their reaction time
  2. Pick up cues as to our opponents intended response as this reduces the number of alternatives and therefore reduces our reaction time
Anticipation
1. Strategy in reducing both types of reaction time
  1. Spatial
    1. Predicting what will happen
  2. Temporal
    1. Predicting when it will happen
Psychological Refractory Period [PRP]
1. Negative side of anticipation
2. If we anticipate something and get it wrong then our reactions are slower
3. If we detect a stimulus and are processing info when a second stimulus arrives, we cannot attend the second until the first is proceessed
  1. This delay makes our reaction time longer and the delay is known as the psychological refractory period (PRP)
