Which type of motor task has a beginning and an end?

• A. Discrete
• B. Serial
• C. Continuous
• D. Open

Answer: (A)

A key idea here is that discrete motor tasks have a clearly defined start and finish. The action is brief and self-contained, beginning when you initiate the movement and ending when the movement is completed—think of a single reach-and-grasp, a quick throw, or pressing a button. In contrast, continuous tasks flow for an extended period without a natural stopping point, so there isn’t a distinct beginning and end within the movement itself. Serial tasks are made up of several discrete actions linked in sequence, so while each component has a start and end, the overall task spans multiple steps. Because the question asks for a task with a definite start and end, the discrete type best fits.
