Motor learning involves learning new muscular coordination through practice. There are two main types of learning - verbal learning which involves words and concepts, and motor learning which involves muscles. Motor learning, also called skill learning, is learning coordinated responses that can be performed proficiently, such as playing the piano, driving a car, or swimming. Motor learning occurs through practice and involves gradual improvement from initial stages that require conscious effort to later stages where skills can be performed without conscious thought. Examples of motor skills include both discrete skills involving a single movement and continuous skills involving repetitive movements.
