Negative feedback in motor control is about keeping movement on target by constantly comparing what you’re doing with what you intend to do and making corrections to minimize error. It’s a feedback-driven, closed-loop process that reduces deviations from the desired state as you perform a task or after practice bouts. For example, if your hand starts drifting while reaching for something, sensory information senses the mismatch and your nervous system tweaks the movement to bring it back toward the target. This ongoing error-correcting action enhances accuracy and consistency, and it’s not limited to beginners—skilled performance also relies on these corrections. The other ideas—amplifying errors, increasing variability, or being limited to early learning—don’t describe what negative feedback does best in motor control.
