Syllabus: How Does Practice Build Skill?
Use the feedback manipulation to examine the challenge framework's prediction that a practice condition can have different effects for different learners. Distinguish accuracy from consistency and randomized feedback allocation from the comparison between ages.
A question to consider. What does the no-feedback retention test add, and what further comparison would be needed before recommending one feedback schedule for all children?
Why this reading
Feedback that helps one learner may burden or support another differently. This experiment compares children and young adults under different feedback schedules, with later tests that help separate success during practice from what remains when guidance is removed.
Before you read
The task requires matching a timed movement pattern with a lever. Participants receive numerical and graphical information about their movement. Retention tests performance after a delay; reacquisition examines performance when practice and feedback resume. Accuracy concerns closeness to the target, while consistency concerns variation across attempts.
Read for
- Reconstruct allocation to full or reduced, progressively faded feedback within each age group. Keep that experimental comparison separate from the nonrandomized comparison between ages.
- Follow the transition from practice to the next day's no-feedback test and then to practice with feedback. Identify what changes at each transition.
- Compare accuracy and consistency separately. Decide which results support a feedback effect and which support an interaction with the learner group.
Consider afterwards
- A learner struggles after feedback is withdrawn but quickly improves when it returns. What additional comparison would distinguish dependence on guidance from rapid relearning?
Editorial context
The study included 20 children and 20 young adults on one laboratory task. Reduced feedback was associated with poorer retention in the children; the adult advantage concerned consistency rather than accuracy. This does not establish a universal rule that children need constant feedback or identify age's causal mechanism. The 2022 feedback meta-analysis supplies a broader, uncertain evidence base against which to assess recommendations from an individual experiment.
