Lecture 2 MCML Flashcards
What is an attractor well?
A well ingrained movement pattern that is hard to change
What are the 4 components about a movement that make up a schema stored in memory
- Initial movement conditions
- Parameters or general knowledge of motor program
- Knowledge of results
- Sensory consequences of movment
Classical conditioning vs Operant conditioning
Classical- associating 2 different stimulus
Operant- includes reward or punishment
Procedural learning vs Declarative Learning
Procedural learning- tasks can be preformed without attention
Declarative learning- can be recalled
What are the 3 stages of Fitts and Posners motor learning
Cognitive stage- processing of task (many errors)
Associative stage- selection of best strategy, less errors
Autonomous stage- minimal attention required
What is the systems 3-stage model for motor learning
Novice
Advanced
Expert
In each stage you unlock more degrees of freedom
Newell’s theory of learning as exploration
Perception has a perscriptive role: the understanding of goals and movements
Perception has a feedback role: knowledge of reformance and knowledge of results
Can learning be measured directly
no
Intrinsic vs extrinsic feedback?
Intrinsic- from within the person
extrinsic- comes from with outside the person and supplements the intrinsic feedback
Knowledge of results is ________ feedback
extrinsic feedback
What is better for motor learning: Massed/blocked OR distributed practice
distributed
What is better for motor learning: Constant or variable practice
variable
What is better for motor learning: contextual interference or lack of contextual interference
contextual interference
What is good for motor learning: Mental practice? Physical Guidance?
Mental practice- good
physical guidance- bad
Compensation vs Recovery
Compensation: Alternative strategy used
Recovery: Acheiving function through original process
The act of ____________ itself may be the primary reason that motor deficits remain
______________ is when a patient learns not to use the affected limbs
Compensating
Learned non-use
How the patient looks practicing skills in a clinical setting is called
preformance
What are the two regulatory conditions of tasks?
Stationary: fixed terrain
Motion: Supporting surfaces, objects, or people
As movement variability decreases, a movement becomes more automtic and is called a ___________ skill
As movement variability increases, new movement patterns are generated to match situation, called an __________ skill
closed
open
What requires more information processing demands: tasks that require transporting the body, or tasks that involve stabilizing the body
transporting
Complexity increases from upper left to lower right
