Motor Control and Learning Part 2
Hick Hyman law
time it takes for a person increases as the amount of possibilites increases
reaction time- time between the onset of stimulus and the start of the response
movement time - time it takes to complete the onset of a movement
response time - time it take to process information then make a response
simple reaction - single stimulus
choice reaction
affected by age, gender, height, LOA
time = movement time + processing speed x log2(n)
movement
speed
accuracy
distance
fits law - haste makes waste
movement time from strat to finish
distance part body part travels
time - more difficult the task. more time it takes
slower movements
rapid + forceful
maximize accuracy
focus of attention
what an athelete is thinking about
internal - focusing on movement
interferes with automatic movement
external - outside of the body
benefical
practice variability
variety of skills and practice conditions
intra skil
interskill
variations of same skill
improves adaptabiity
using different skills together
improved learning through cognitive effort required
three stage of motor learning
associative
cognitive
autonomous
beginners - rely on working memory
decreased reliance on memory
required deliberate practice
minimal cognitive effort
improved anticipation and decison making
explicit v implicit
explicit
coached focused
implicit
little to no instruction
less break down under pressure
increase rsistance to fatigue
