Effects of self-control and instructor-control feedback on motor learning in individuals with cerebral palsy.

★ The Verdict

Letting kids with CP choose when they hear performance feedback helps them keep dart-throwing skill better than teacher-set schedules.

✓ Read this if BCBAs working on motor goals with school-age clients who have CP or similar motor disorders.
✗ Skip if Clinicians focused only on language or social skills with no motor component.

01Research in Context

01

What this study did

Hemayattalab (2014) asked boys with cerebral palsy to practice dart throwing. Each boy got one of three feedback plans. Some chose when they heard how close the dart landed. Others heard feedback only when the teacher picked. A third group got no feedback at all.

The boys threw darts for several days. Later the team tested who still hit the target best without any help.

02

What they found

The boys who picked their own feedback times kept the best aim later. They hit closer to the bull’s-eye on both the next-day test and a new target test. The teacher-controlled group did worse, and the no-feedback group did worst.

Letting the learner choose when to hear results helped the skill stick.

03

How this fits with other research

Gardner et al. (1977) saw the same boost with adults learning blood-pressure control. When adults chose when they heard the beep, they raised or lowered pressure 10–15 % and kept the skill after feedback stopped. Rasool shows the self-control trick also works for kids with CP and a motor task.

Wheatley et al. (1978) paired simple beeps with small prizes to calm hyper kids or wake up sluggish ones. Rasool adds that the timing choice, not the prize, is the active piece.

Robinson et al. (2011) used mCIMT-BiT to help young kids with CP use their weaker arm more. Both studies used random assignment and kept gains for weeks, but Rasool used feedback timing while B used arm restraint. Together they show different levers can lock in motor gains.

Why it matters

You can give clients the remote. Ask, “Do you want to know how you did now or after the next throw?” This tiny choice costs nothing and may double how well the skill stays. Try it in any motor goal: throwing, balancing, or using a utensil. One question, big payoff.

03Original abstract

In this study we investigated the effects of "self-control and instructor-control feedback" on motor learning in individuals with cerebral palsy (CP). For this reason 22 boy students with CP type I (12.26±3.11 years of age) were chosen. They were put into self-control feedback, instructor-control feedback and control groups. All participants practiced dart throwing skill for 5 sessions (4 blocks of 5 trails each session). The self-control group received knowledge of results (KR) feedback for half of their trials whenever they wanted. The instructor-control group received KR feedback after half of both their good and bad trails. The control group received no feedback for any trails. The acquisition test was run immediately at the end of each practice session (the last block) and the retention and transfer tests were run 24h following the acquisition phase. Analyses of variance with repeated measures and Post hoc tests were used to analyze the data. According to the results of this study, individuals with CP have the ability of acquiring and retaining a new motor skill. Also, it was found that self-control feedback is effective than instructor-control feedback on learning of a motor task in individuals with CP as in the average population. These findings show that rules regarding feedback also apply to people afflicted with CP.
