Subclaims¶

q3 i? Among 160 adolescents, rest duration the night before cognitive testing was negatively associated with 3-back response time (β = −0.22, p = 0.005), the only association surviving false-discovery-rate correction. → Stefansdottir 2020

q3 · i? · associational · r2

Linear regression analysis in 160 adolescents adjusted for ADHD diagnosis, weekly videogame use, and 1-back response time; the printed standardized beta was β = −0.22 [−0.38, −0.07] (p = 0.005), described as an "inverse correlation between total rest times the night prior to the cognitive task and 3-back response times".

"determined that only the association between rest duration the night before cognitive testing and 3-back response time (p = 0.005) fell below the critical p value of 0.006"

Discussion¶

Related Claims¶

• Sleep the night before cognitive testing resembles weekly averages except for an earlier mid-sleep time — related
• Adolescents with 7 hours or less total rest time show longer 3-back response times, both acutely and averaged over the week — related
• Free-living sleep measures show no association with visual attention task performance in older adolescents — related
• Weekly average sleep measures show no association with working memory performance in older adolescents — reports the opposite
• Older adolescents show high night-to-night variability in free-living sleep duration, which may obscure sleep-cognition associations — related
