Final answer:
Motor learning is true to be concerned with developing and refining motor skills, not just the correctness of the movement. It involves the cooperative work of the brain, nerves, and muscles.
Step-by-step explanation:
The statement regarding motor learning is true. Motor learning is concerned with the process of acquiring and refining motor skills. It is not solely about the correctness of the movement but rather about the improvement and optimization of motor actions through practice and experience. Motor learning involves the brain, nervous system, and muscles to allow for the development of coordinated movement.
Although correctness can be a part of learning, the definition itself does not mandate that the movement must be correct, only that it improves through practice.
