这项研究调查了婴儿期睡眠与学龄前儿童认知表现之间的前瞻性联系。 65 名婴儿的母亲在婴儿 1 岁时完成了睡眠日记，孩子在 4 岁时完成了韦克斯勒学前儿童和初级智力量表的两个子量表，指数一般认知能力和复杂的执行功能。与假设一致的是，婴儿在夜间睡眠的比例更高，他们的执行功能表现更好，但一般认知能力并没有更好。在控制了家庭社会经济地位和先前的认知功能后保持的关系。这些发现表明，成年人中记录的睡眠对于高阶认知的特殊重要性可能在生命的早期就显现出来。
This study investigated the prospective links between sleep in infancy and preschoolers' cognitive performance. Mothers of 65 infants completed a sleep diary when infants were aged 1year, and children completed two subscales of the Wechsler Preschool and Primary Scale of Intelligence at 4years, indexing general cognitive ability and complex executive functioning. Consistent with hypotheses, children getting higher proportions of their sleep at night as infants were found to perform better on executive functions, but did not show better general cognition. Relations held after controlling for family socioeconomic status and prior cognitive functioning. These findings suggest that the special importance of sleep for higher order cognition, documented among adults, may appear very early in life.
