Which statement describes motor programmes in relation to open and closed-loop perspectives?

• A. Motor program is structured the same way as open loop but its commands are changed by the need to correct errors.
• B. Motor programs cannot be altered during execution.
• C. Motor programs are only used in closed loop.
• D. Motor programs replace perception.

Answer: (A)

When we think about motor programmes, they are preplanned sequences of motor commands that allow a rapid, well-timed action to be produced with minimal ongoing conscious control after initiation. That mirrors the open-loop idea, where once the program starts, the movement unfolds largely without relying on real-time feedback. But the programme framework isn’t rigid; when sensory feedback indicates an error, the commands within the programme can be adjusted to correct the movement. This combination—a prestructured plan that can be modulated by feedback to fix errors—best describes how motor programmes relate to open and closed-loop perspectives. The other statements don’t fit: motor programmes aren’t fixed and unchangeable during execution, they aren’t used only in closed-loop, and they don’t replace perception.
