Which term describes sending a motor plan to the brain, comparing with prior performance, and detecting potential errors before/after execution?

Feed-forward praxis captures the anticipatory side of movement planning. It involves forming a motor plan and using prior experiences to predict how that plan will unfold, comparing it with what has worked before to prevent errors before they occur and to refine the action as it unfolds. This means the brain is not just issuing a command to the muscles, but actively forecasting the sensory consequences and adjusting commands in advance based on stored memories of successful executions. While ideation is about generating the initial concept of the movement and execution is carrying it out, feed-forward praxis centers on anticipating and preventing mistakes through predictive planning and comparison with past performance. Sensory feedback after movement still plays a role, but the distinctive feature here is the proactive, predictive control that helps detect and minimize errors before (and as) movement happens. For example, when learning a new tool-use task, you use past attempts to anticipate grip, force, and timing, adjusting your plan before you act to reduce errors.
