motor control Flashcards
What are the three factors for movement?
Individual, task, environment
What is the degrees of freedom problem?
Choosing among equivalent solutions and then coordinating the many muscles and joints involved in a movement
Individual’s perception on movement involves?
Both peripheral sensory mechanisms and higher level processing that adds meaning to afferent information
What is the principle of self organization?
When individual parts come together, its elements behave collectively in ordered way- no need for higher center
What is the control parameter?
A variable that regulates changes in the behavior of the entire system
Performance vs learning?
Performance- temporary change in motor behavior
Learning- relatively permanent change in behavior
What is the closed loop theory?
Sensory feedback from ongoing movement is compared with the stored memory of the intended movement
What is the open loop theory?
The execution of preprogrammed movements without perceptual feedback
What is intrinsic feedback?
Via the various sensory systems
What is extrinsic feedback?
Come from the external resource
