Theories of Motor LearningAssumptions Clinical Implications Limitations
Adams Closed Loop Theory - Closed Loop - Sensory feedback is used for the - Perform same exact mvmt repeatedly to - Can’t explain accurate performance of
ongoing production of skilled mvmt one accurate end point open loop mvmts made in absence of
- Slow mvmts - Increase practice Increase learning sensory feedback
- Relies on sensory feedback (Sherrington) - Errors produced during - May be impossible to store separate
- Blocked Practice learningincrease strength of incorrect perceptual trace for every single mvmt
- Errors = Bad! Needs to be accurate! perceptual trace - Variability of mvmt may improve
- Memory trace - initiation of mvmt motor performance of task
- Perceptual trace - built up over a period of
practice & is the reference of correctness.
- Improvements = Increased capability of
performer to use the reference in closed loop
Schmidt’s Schema Theory - Open Loop - Optimal learning task practiced under - Differences b/w children & adults w/
