M8 Open-Loop Control & Motor Programs & GMP Flashcards
A surgical procedure that involves cutting one or more of an animal’s dorsal roots, preventing nerve impulses from the periphery from traveling to the spinal cord
Deafferentation
A control mechanism that produces mainly genetically defined actions such as walking
Control pattern generator
After deafferentation, monkeys were still able to make limb positioning movements, but the movements were not as __
Accurate
Which of the components are involved in open-loop control?
Effector, Executive
Which of the following is NOT TRUE about open-loop control systems?
Open-loop control systems include feedback as a component
What was the main finding of the Henry & Rogers (1960) experiment that provides support for motor program theory?
As response complexity increased, reaction time increased
What term defines the point at which the muscle commands have been sent and can no longer be retrieved or modified?
Point of No Return
A type of system control in which instructions for the effector system are determined in advance and run off without feedback
Open loop control
A prestructured set of movement commands that defines the essential details of skilled action, with minimal (or no) involvement of sensory feedback
Motor program
The concern that simple program theories cannot account for the production of novel, unpracticed movements
Novelty problems
The concern that simple program theories would require an almost limitless storage capacity for nearly countless different movements
Storage problem
Circuits in the spinal cord that are capable of producing oscillations
Control pattern generator
What can be done to examine open loop control?
Interrupt flow of sensory information
