Work by day and sleep by night, do not sleep too little or too much: Effects of sleep duration, time of day and circadian synchrony on flanker-task performance in internet brain-game users from teens to advanced age.

摘要: Research elucidating the effects of sleep and circadian rhythm on cognitive performance is advancing, yet many important questions remain. Using flanker-task scores from a large internet sample (N = 48,881) with repeated measures linked prior-night self-reported duration, we analysed relationship between time day task performance, chronotype synchrony in participants aged 15-80 years. Results indicate peak at 7 hr habitual point to variable effect deviation duration depending users' age. Time-of-day were notable for steady decline up until 01:00 hours-02:00 hours group as whole, which was accounted by nighttime deterioration trials requiring inhibitory executive functioning, particularly older subjects. Analyses did not demonstrate an advantage playing self-identified chronotype. strengthen findings indicating inverted U-shaped across broad spectrum age groups. These underscore importance daytime tasks function, especially elderly people. Findings highlight utility large-scale data contributing science.
