Adolescent sleep and working memory performance

摘要: Several studies have reported a link between poor adolescent sleep and academic achievement. Evidence suggests that particular intellectual abilities are integral in achievement may be susceptible to loss. One such ability is working memory. The aim of the present study was investigate loss memory performance. A total 143 adolescents (aged 13–18 years, mean age = 14.9 ± 1.4 43% boys) volunteered for study. All participants completed an online questionnaire tasks letter-number sequencing operation span task. Participants were grouped into sufficient sleepers (i.e. more than 9 h; n 43), borderline (8 57) insufficient (less 8 h sleep; based on their self-reported time school nights. reporting performed worse both task (both P 0.03; medium large effect sizes) compared with sleepers, but not sleepers. No other significant differences groups found. Compared groups, going bed later (P < 0.0001), taking longer fall asleep 0.0001) experiencing greater daytime sleepiness 0.05). These findings suggest nights optimum Future experimental needed support current study’s findings.
