Week 7 Flashcards
What is a motor learning process
- a set of events or occurances that lead to a product or state of change
-largely assumed
Relatively permanent change
-change of state that is not readily reversible
Learning
-should have some lasting effect
-you are a different person
-some underlying change that is stable
Hebbian processes
-neurons that fire together, wire together
-the more common pathways fire, greater chances they will fire in this pattern again
Activation in networks can be observed by?
-looking at outputs (electrical energy)
-looking at energy consumption (bloodflow)
Functional connectivity analysis
-examines the time series of FMRI data in different brain regions
-examines strength of these relationships with regions of interest
-measure conductivity of blood flow between one area to another
Functional connectivity and learning
-some studies have shown that functional connectivity can predict motor learning
Adaptation
-the trial to trial modification based on error feedback
-person must de-adapt after the behaviour
-show an after effect
-transient change
How to measure adaptation
-aquisition tests
How to measure learning
-retention and transfer tests
Different types of performance curves
-linear
-negatively accelerated
-positively accelerated
-sigmoid (S)
Factors affecting performance
-between participants variability
-within-person variability
-ceiling effects
-floor effects
Ceiling and floor effects
-its much harder to improve your score in gymnastics from a 9 to a 10 than from a 5 to a 6
-also much harder to reduce score in golf when your stroke number is high not low
Retention tests
-testing participant on same task after a time interval
Transfer tests
-testing participant on new variations of the practiced task
