Syntes: Lo, Bennion & Chee 2016 — post-learning sleep restriction and prioritization (SLEEP-008)

Källa: https://doi.org/10.1111/jsr.12424 (Journal of Sleep Research 25:664–672). OA (CC BY).

Metadata

• ID: SLEEP-008
• Tier: RCT
• N / design: 56 adolescents (15–19), parallel groups; encoding then 7 nights × 5 h vs 9 h TIB
• Population: adolescents
• Subject: Sleep restriction can attenuate prioritization benefits on declarative memory consolidation

Finding

1. Prose passage with half the content highlighted (prioritized); free recall initially, after 1 week of sleep opportunity manipulation, and at 6 weeks.
2. No main effect of group on recall (F(1,43) = 1.13, P = 0.29); authors: no significant differences in memory performance at any time point between SR and control for HL, nHL, or total content.
3. Prioritization benefit grew from immediate to 1 week for control (t(25) = 2.47, P = 0.021, d = 0.99) but not SR (t(29) = 1.45, P = 0.16, d = 0.26); three-way interaction ns.
4. Authors note consistency with Voderholzer et al. 2011 (post-learning multi-night restriction null on consolidation).

Limits

• Post-encoding consolidation design (not pre-learning encoding restriction).
• Boarding/protocol setting; Singapore adolescents; N moderate.
• Outcome is free recall of a prose passage with a prioritization manipulation, not classroom factual learning after short sleep before encoding.
