q3 i? Neither acute nor weekly sleep parameters were associated with response times or accuracy on the Posner cue-target task, and the ≤7 h vs >7 h rest groups did not differ. → Stefansdottir 2020

q3 · i? · associational · r3

Null result from linear regressions in 160 adolescents adjusted for ADHD, videogame use, and valid-cue baseline measures; the authors suggest "the task lacked complexity, the variability of free-living sleep parameters was too high, or both", noting the 9-minute task may have been too short.

"Surprisingly, we found no associations between response times on the visual attention task and sleep parameters measured the night prior to cognitive testing or over the entire week (Table 5)"

• Weekly average sleep measures show no association with working memory performance in older adolescents — related
• N-back response time increases and accuracy decreases with cognitive load, and Posner cue conditions differ in speed and accuracy trade-offs — related
• Shorter time in bed the night before testing is associated with slower 3-back response times in older adolescents — related
• Adolescents with 7 hours or less total rest time show longer 3-back response times, both acutely and averaged over the week — related
• Older adolescents show high night-to-night variability in free-living sleep duration, which may obscure sleep-cognition associations — related
• Experimental sleep restriction causally extends adolescent sleep-loss effects beyond sleepiness to attention and learning — related
• Five nights of sleep restriction cause lower quiz performance in a simulated classroom among adolescents — related
• Sleep and consolidation support semantic memory development, suggesting delayed school start times may benefit memory — related
• Polysomnographic sleep parameters did not differ between afternoon- and evening-trained groups and did not correlate with memory consolidation measures — related
• Sleep the night before cognitive testing resembles weekly averages except for an earlier mid-sleep time — related
• A 30-minute rest and a full night's sleep each add small further gains in mental multiplication output, with accuracy unchanged — related
