Fewer and less gross errors. Capability to detect and identify own errors. Can do other task at same time. Appropriate movement pattern. Changes during learning Rate of improvement follows negative acceleration curve.
Beginners freeze degrees of freedom on certain limbs.
Begin new skill with preexistent preferred coordination pattern. EMG patterns show changes in muscles used to perform skill. Movement becomes more efficient. Displacement is first kinematic goal achieved followed by velocity and acceleration. Vision become more focused and applicable.
