In development in stacked position, which progression step is the hardest?

• A. Feedback (easiest)
• B. Demonstrate
• C. Capacity with feedback
• D. Capacity (hardest)

Answer: (D)

The idea being tested is how motor performance becomes more demanding as cues and support are removed. In stacked-position development, you move from showing the action (the learner sees how it’s done), to practicing with ongoing feedback (you guide and correct as they go), to performing with capacity (the learner can do it with only minimal or no external prompts). The hardest step is capacity—doing the task independently, without feedback or prompts, requires accurate motor control, self-monitoring, and the ability to maintain the correct pattern on your own. The earlier stages are easier because demonstrations and feedback provide guidance that supports achieving the movement.
