Which motor learning element contributes MOST to retention of a motor skill?

• A. Performance under variable conditions
• B. Manual contact to guide the patient
• C. Summary knowledge of results
• D. Practice of the motor skill

Answer: (D)

Retention of a motor skill hinges on practicing the movement itself enough to build a stable motor memory and an automatic pattern of control. Repeated practice strengthens the neural pathways that govern the action, refines the motor program, and reduces cognitive load during performance. This consolidation makes the skill durable over time and across opportunities to perform it again, even after a break. Actions like performing under variable conditions help with adapting the skill to new contexts, which is valuable for transfer, but the most direct driver of long-term retention is simply continuing to practice the skill itself. Guidance or manual support can sometimes make learning easier in the moment, but it can also create reliance on external help and limit active problem solving, which may hinder retention when guidance is removed. Finally, providing summary knowledge of results supports motivation and awareness but doesn’t achieve the same depth of memory consolidation as actual, repeated practice of the movement.
