Feedforward Control

Shrink Definition

Feedforward control is planning and launching a movement based on prediction, before any feedback arrives, rather than reacting to it. Fast actions like a tennis swing happen too quickly to correct mid-flight, so the brain predicts and pre-programs them. It complements feedback, which adjusts slower movements. Skilled performance relies heavily on good prediction.

Plain language

Planning a movement by prediction before any feedback arrives.

Shrink Insight

Fast skill runs on prediction, because feedback arrives too late.

Why it matters

It explains how fast, skilled movements work when feedback is too slow. It highlights the role of prediction in skill.

Common misunderstanding

People think all movement is guided by reacting to feedback. Fast actions rely on feedforward prediction, since feedback comes too late to help.

Shrink Perspective

Skill anticipates as much as it reacts.

Shrink Reflection

Which quick actions do I complete before I could react to them?

Shrink Step

For fast skills, train prediction and preparation, not just reaction.

Shrink Minute

Notice a quick action you complete before you could react to it.

Shrink Takeaway

Fast skill is predicted, not reacted.
