What is the process through which a person develops the ability to perform and refine a task called?

The correct choice for this question is motor learning, as it specifically refers to the cognitive process involved in acquiring and improving skills related to movement. Motor learning encompasses the understanding of how movements are practiced, retained, and refined over time through experiences and feedback. It involves complex interactions between perception, cognition, and action, which help individuals adjust their movements to perform tasks more effectively.

Skill acquisition, on the other hand, is often a broader term that can refer to the overall process of learning a skill but does not emphasize the cognitive development aspect as distinctly as motor learning. Physical training focuses more on the conditioning and physical requirements to enhance performance, while technique development deals with the specific methods or strategies used to improve the execution of skills. Thus, the focused nature of motor learning makes it the most accurate term for the process of developing and refining performance abilities.
