Spanking and parental verbal aggression during early childhood: Association with later academic achievement and the mediating role of executive function

Abstract 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 2010–2011 ( n = 11,421) to examine the associations between early childhood exposure to spanking and parental verbal aggression and subsequent academic achievement. We also investigated the mechanism for these associations by exploring the mediating role of executive function within those associations. Findings revealed that spanking and parental verbal aggression in kindergarten and first grade were negatively associated with reading and math scores in fifth grade, controlling for demographics and initial academic performance. Executive function (i.e., inhibitory control, cognitive flexibility and working memory) accounted for more than half (50%–57%) and more than one fourth (24%–31%) of the total effects of spanking and verbal aggression on academic achievement, respectively. Findings provide important evidence for early intervention programs aiming to promote children's academic achievement and executive function by interfering or preventing harsh discipline. Highlights We examined the pathway from spanking and verbal aggression in early childhood to academic achievement in later school years through executive function. Path analysis results show executive function was a significant mediator in the negative associations between academic achievement in fifth grade and early exposure to spanking and aggression. Besides avoiding harsh parenting, intervention programs to support child academic achievement could also target promoting executive function development.
