Motor learning: retention, transfer, and feedback

Distinguish performance from learning

A movement may improve during a session because the person warmed up, received continuous feedback, or learned how to satisfy the immediate instruction. Those changes can be useful. They do not by themselves demonstrate a durable skill.

Motor-learning research distinguishes acquisition during practice from retention after a delay and transfer to another context.[1] For rehabilitation, that distinction asks whether an improved chair rise remains available tomorrow and whether it helps with another chair at home.

Choose the task you want to carry over

Break a difficult task down when that makes practice manageable, but return to the whole activity. A supported hinge can help introduce a movement. Lifting a shopping bag also requires grip, load choice, object position, and decisions about the environment. The isolated drill covers only part of that task.

Define what success means: reach a shelf, rise with less hand support, change direction while walking, or carry an object to another room. A visually tidy repetition is not automatically the outcome the person values.

Vary one relevant condition

Keep the variation appropriate to current capacity. A change in chair height, object location, or sequence can be enough. Unsafe balance disturbances or unnecessary distractions do not make a session more scientific.

Understand blocked and interleaved practice

Blocked practice repeats one version before moving to the next: AAA, BBB, CCC. Interleaved practice switches among versions: ABC, BCA, CAB. Switching can make practice feel less smooth because the person must repeatedly retrieve or adapt the solution.

A systematic review compared random-order practice with blocked practice and found an average transfer advantage for random practice. The studies varied considerably, and results in applied settings were less certain than laboratory findings.[2] Random order is one form of interleaving; the predictable ABC sequence above illustrates switching, not the precise schedule used in every study. Choose the amount of variation around the learner and the activity.

Try the movement with less prompting

Use a cue that directs attention toward the relevant action. For some people, an instruction about moving an object is clearer than several body-part instructions. For others, a specific positional cue helps introduce the task. Keep the cue that improves understanding and performance, and assess whether it remains necessary.

Ask the learner to describe the task in their own words. Then observe a later attempt with less prompting. This gives more information about independence than repeating a coached performance at the end of the same session.

Keep a practice record

Write down the task, support, cue, immediate result, and later result separately. Add one relevant transfer situation. When the skill disappears later, examine the task demands and feedback conditions before concluding that the person is weak, unmotivated, or “moving wrong.”
