Document Summary
Motor learning practical contexts: relatively permanent change in the control elements of the nervous system that occurs as a result of practice and not attributed to maturation, not directly observed or measurable, performance is measured instead. Measuring motor behaviour: performance, measuring movement or outcome (eg. error rate, number of correct responses, number of goals, time, kinematics, muscle activity) Neurophysiological changes with learning: plasticity, brain is highly malleable, changes in synapse efficiency and connections, changes in cortical representation. Factors affecting learning: feedback, effective practice requires feedback of the movement to promote learning, knowledge of results (kr, knowledge of performance (kp, both internal and external sources, all feedback is useful, practice, type of practice. Length of rest intervals (mass vs distributed: variable (multiple tasks) vs constant (one task, repetitive (blocked) vs variable (random) Important that feedback is: compared to previous performances, specific to activity/skill being performed and to the performer.
