In this registered report, we evaluated how sleep is related to school functioning. Using data from the Future of Families and Child Wellbeing Study (N = 3002), we evaluated a series of structural equation models evaluating whether sleep at age 5 has a direct or indirect effect on academic achievement, executive function and classroom behaviour at…

Spanking and parental verbal aggression are potentially toxic stressors that can negatively affect children's academic achievement by disrupting mental skills like executive function. Yet little empirical evidence has been provided for this mediating pathway. This study used data from the Early Childhood Longitudinal Study Kindergarten Cohort of…

Executive attention, the attention necessary to reconcile conflict among simultaneous attentional demands, is vital to children's daily lives. This attention develops rapidly as the anterior cingulate cortex and prefrontal areas mature during early and middle childhood. However, the developmental course of executive attention is not uniform among…

Structural equation models were used to examine pathways from maternal depression and early parenting to children's executive function (EF) and externalizing behaviours in the first nationally representative study to obtain direct assessments of children's kindergarten EF skills (i.e., the Early Childhood Longitudinal Study Kindergarten Class of…

Using data from the Early Childhood Longitudinal Study Kindergarten Class of 2010-2011 (n = 11,000), this study examined the developmental outcomes of 5-year-old children in multigrade classrooms (combined prekindergarten and kindergarten classrooms serving 3-, 4-, and 5-year-olds) compared with those of 5-year-olds attending kindergarten-only…

Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is…

Children showing poor executive functioning may not fully benefit from learning experiences at home and school and may lag behind in literacy skills. This hypothesis was tested in a sample of 276 kindergarten children. Executive functions and literacy skills were tested at about 61?months and again a year later. In line with earlier studies,…

The effects of low income on children's adjustment might be accounted for by disruptions to hypothalamic-pituitary-adrenal (HPA)-axis activity and to the development of effortful control. Using longitudinal data and a community sample of preschool-age children (N?=?306, 36-39?months) and their mothers, recruited to over-represent low-income…
