Document Summary
Rapid motor actions leave little time for corrections based on sensory feedback. Producing rapid, complex mvt requires a clearly organized plan. Biggest thing is there is no feedback mechanism (but not 100% gone) or comparator. S id: what info is available and more relevant. Response programming: planning and generating chosen response i. e. in baseball, when batter makes decision about when to swing, the decision is made and they are committed with little time to modify the action (all or none) Rmas with minimum feedback (open-loop) executive: processes sensory info, selects and programs appropriate response (stages of info processing) Effector: component of peripheral motor system that generates desired motor response (mp sc motor periphery) Control using pre-structured motor command with minimal role of visual/proprioceptive feedback from motor periphery: rmas minimize (not eliminate) contributions from sensory feedback. Two ways to operate: slow movement, long duration dominated by feedback processes, very fast or brief actions dominated by open-loop.
