Subject and technical command
Check command of the actual literature: working memory training transfer limits, spaced retrieval, HRV or EEG biofeedback, sleep and aerobic exercise effects on BDNF. Ask which claims they refuse to make.
Evidence to listen for
- Knows the material or discipline well beyond the level they teach
- Holds the qualifications, licences, or certifications required, and they are current
- Can answer an unexpected question honestly rather than bluffing
- Keeps learning in their own field
Five-point scoring guide
Knowledge barely ahead of the learners; bluffs when asked something unexpected.
Adequate on the syllabus only; gaps show under questioning.
Solid command of the material for the level taught.
Depth well beyond the taught level; comfortable being asked anything.
Cites specific studies and meta-analyses, distinguishes near from far transfer, and openly names where evidence for brain training is weak.
