ch. 9 Flashcards
as a motor still is learned, what happens
more efficient methods are established in the form of…
-muscle movements
-information processing
describe effort of a motor skill
as a motor skill is learned, effort reduces
-EVEN when an individual is overlearning something
-shown by physiological measures like oxygen consumption + pupil dilation
motor learning
set of PROCESSES associated with PRACTICE/EXPERIENCE leading to RELATIVELY PERMANENT changes in capability for skilled movement
can learning be observed directly
NO
how is learning observed
through changes in the CNS
-sensorimotor processing areas in the brain
-changes in pattenrns of muscular action
learning is observed based on ____
BEHAVIORAL changes
learning affects performance before/after removed
AFTER
performance/learning curve reflects internal/external state
INTERNAL
-aka amount of habit
x + y of performance curve
trials vs. performance
2 categories of experimental variables
performance
learning
Fleishman + Rich
(think RICH, crank money)
2-hand coordination task following target through movements of 2 crank angles (forward/backward + L/R) for 1-minute trials
-subjects moving L/R improved with practice
-more practice = more improvement
Bahrick, Fitts, Briggs
-men on continuous tracking task with varying width of approval (5%, 15%, 30%)
-showed that it is important to be transparent with the % leniency used in scoring
2 instances where ceiling/floor effects occur
simple tasks
certain complex tasks
how do ceiling/floor effects occur in simple tasks
learn + maxmize within a few atempts
how do ceiling/effects occur in certain complex tasks
some complex tasks are automatic + therefore hit ceiling
