Motor Control Theories Flashcards
(14 cards)
Proprioceptive/Exteroceptive feedback
Movement-produced feedback
A reference of correctness against which feedback is compared to define an error
Comparator
GMP plus Parameters
closed-loop control
System that carries out the act
Effector system
GMP plus Parameters but no time
open-loop control
Executive system
Decides and Prepares the act
Where is the “Comparator” in humans?
Cerebellum
Motor program, Spinal cord, and muscles.
Effector system
Stimulus identification, Response selection, and Movement programming.
Executive system
- A set of instructions that structures the skill in advance and allows it to be run off as a unit w/o online modifications.
- Organized in the motor programming stage.
- Reflects motor memory for a particular class of actions
- Solves Storage and Novelty problems
General Motor Program (GMP)
- A set of instructions that structures the skill in advance and allows it to be run off as a unit w/o online modifications.
- Organized in the motor programming stage.
- Reflects motor memory of a specific movement
Simple Motor Program
anticipated sensory consequences of the movement that should be received if the movement is correct.
Feedforward
Invariant features
Fundamental features of a skill (class); the pattern that characterizes kill.
The proportion of the amount of time required by each component of a skill is FIXED regardless of total duration of the movement performed,
Relative Timing (Rhythm)
