It is well known that the characteristics of nighttime sleep is strongly linked to cognitive abilities in daytime. However, studiesinvestigating the influence of poor-sleep characteristics on pre-adolescent children's cognitive abilities are relatively few. Thepresent study aimed at investigating the influence of night-time sleep characteristics on pre-adolescent children's cognitiveabilities by utilizing objective indicators. To achieve this goal, we analyzed the relation between attentional control ability measuredby standardized behavioral task and nighttime sleep characteristics quantified by actigraph measurement. The results revealeda significant correlation between ability of executive attention and total sleep time, i.e. total length of uninterruptedsleep. To be more specific, focal attention of children with long total sleep time was more easily distracted by goal-irrelevantinformation than that of children with short total sleep time, which indicates that sub-component of attentional controlsubserved by prefrontal cortex is particularly susceptive to sleep characteristics. The implication of this findings are discussedin the context of previous studies on the relation between children's nighttime sleep characteristics and their cognitive functions.
