Experiments on Motor Learning in Patient Populations Show That

Experiments on motor learning in patient populations show that:

A) Functional tasks cannot be performed well unless the underlying movements are first practiced in isolation in preparation for the task.
B) When learning to regain fast movements (gait,reaching) ,patients should first master the movements at a slow speed and then speed up in a smooth,controlled manner.
C) Patients with poor expressive memory may still learn motor tasks with practice.
D) Patients learning standing balance tasks do so more effectively if they focus on their body and their movements,rather than on features of the external world.
