q3 i? No weekly sleep parameter (rest time, sleep time, efficiency, WASO, or variability) was associated with n-back response times or accuracies at p < 0.05. → Stefansdottir 2020

q3 · i? · associational · r2

Null result from the same linear regression models in 160 adolescents; the authors suggest a floor effect, since "over 88% averaged less than the recommended 8 h time-in-bed over the week", and compensatory night-to-night variation may have obscured associations.

"Next, we examined the association between working memory and weekly averages of sleep parameters and found no associations with p values below 0.05 (Table 4)"

Related Claims¶

• Sleep the night before cognitive testing resembles weekly averages except for an earlier mid-sleep time — related
• Older adolescents show high night-to-night variability in free-living sleep duration, which may obscure sleep-cognition associations — related
• Adolescents with 7 hours or less total rest time show longer 3-back response times, both acutely and averaged over the week — reports the opposite
• Free-living sleep measures show no association with visual attention task performance in older adolescents — related
• Five nights of sleep restriction cause lower quiz performance in a simulated classroom among adolescents — related
• Shorter time in bed the night before testing is associated with slower 3-back response times in older adolescents — reports the opposite
• 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
• Experimental sleep restriction causally extends adolescent sleep-loss effects beyond sleepiness to attention and learning — related
• A 30-minute rest and a full night's sleep each add small further gains in mental multiplication output, with accuracy unchanged — related
