Information processing in motor learning and control Flashcards
What is the underlying basis of the OPTIMAL theory of motor learning?
Factors that underlie intrinsic motivation affect performance and learning (build confidence)
What are the 3 variables in the OPTIMAL theory?
- enhance expectancy
- learner autonomy
- external focus of attention
What is an example of enhanced expectancy-perceived task difficulty?
Active people, with your experience, usually do well on this task
What is an example of enhanced expectancy-definitions of success?
putting in a big circle and small circle. small circle individuals do better
What is an example of enhanced expectancy-social comparative feedback?
subjects receive their own score and then you tell them
“The average score on this test was 20% worse then yours”
People you tell this to will do better than if you told them they did poorly.
What are the two ways you can provide autonomy to your patient?
- Allowing self controlled use of assistive devices
- Allowing incidental choices: have choices available for them to think about
T or F
A combination of enhanced expectancies, autonomy support, and external focus will make for a more accurate performance.
True
What is the correct order of movement planning?
Stimulus identification
response selection
response execution
What is response selection?
Compare choices from existing motor memory stores
What is response execution?
- muscles to perform the task
- onset of muscle action
- muscle contraction force
What is reaction time?
The time period btw onset of a signal and initiation of required movement
Typical reaction time
1-200 milliseconds
What reaction time has one signal, one movement?
Simple reaction time (go)
What reaction time has more than one signal, different response to each signal?
Choice RT (stop light)
What reaction time has more than one signal, one response?
Discrimination RT (big stars)
