AS PE Motor Control
AQA AS PE Open & Closed Loop Control
Term | Definition |
---|---|
Skilful play within a game relies on effective information processing. According to Adam's closed loop theory, two pieces of information called traces are used to control movement. Name these two traces. | Memory trace and Perceptual trace |
Describe how the memory trace (MT) and perceptual trace (PT) are used to produce skilled movement. | MT-initiates movement MT-based on experience PT-controls current movement Learning involves development of PT through feedback. Traces compared-Match-movement continues/Mismatch-corrections (during performance) Adjusted MT = new motor programme |
What are the characteristics of an open loop control system? | Pre-planned/well learnt movement/ without conscious control Once initiated no modification No feedback during movement/only after movement Very quick/limited time/ballistic movements Carried out in a stable environment/closed skills. |
Explain why an open loop control system is not applicable to all types of skills. | Too many stored movements required for memory capacity Not all environments are stable Cannot accommodate new skills Cannot accommodate flexible movement pattern Not applicable to open skills Many skills have time for feedback during performance |
