Practice with sleep makes perfect: sleep-dependent motor skill learning
Controlled motor-sequence experiment showing ~20% faster performance after a night of sleep versus no significant change after an equivalent waking interval; improvement correlated with stage 2 NREM sleep, especially late-night stage 2.
Design
- Within-subject motor skill paradigm comparing 12 h intervals containing sleep vs wake
- Outcome: speed of sequential finger movements with accuracy preserved
Headline result (abstract)
- ~20% increase in motor speed without loss of accuracy after sleep; wake interval showed no significant gain
- Correlation: overnight performance gain associated with amount of stage 2 NREM, particularly late in the night
Evidence hygiene
- Laboratory motor-learning task—supports sleep scheduling rationale for skill athletes/students but is not a clinical insomnia treatment trial.
