Which description best defines serial motor skills?

• A. Discrete movements that are tied together (obstacle course)
• B. Information is received from all sensory systems during and after the task
• C. Requires ongoing monitoring of the environment
• D. Performed in a stable and predictable environment

Answer: (A)

Serial motor skills are sequences of discrete movements performed in a specific order to complete a task. Each element has a clear start and end, but the actions must be executed in a prescribed sequence to produce the overall action. An obstacle course illustrates this well: you navigate multiple distinct movements in a set order to finish the course, rather than just a single action or a continuously flowing motion.

This description captures what makes serial skills unique—the linking of discrete components in a defined sequence to achieve a goal. Choices that emphasize sensory processing, constant environmental monitoring, or a stable environment describe performance conditions or feedback aspects rather than the structural nature of the skill itself.
