Sample
Synthesis
Population
N/A (synthesis of prior cognitive-load studies).
Design
Names and organizes the expertise-reversal effect as a form of the redundancy effect. Grade-D synthesis; foundational for the ATI framing.
Key findings
The canonical statement that methods effective for novices (worked examples, direct guidance) lose effectiveness and can backfire as expertise rises — instruction must be tailored to prior knowledge. A review, not primary evidence.
Genetic confound
Prior-knowledge interaction, not ability/g.
Replication notes
Cite for mechanism (redundancy) and ATI framing, not effect sizes.
