Executive function (EF) and effortful control (EC) are two similarly defined constructs implicated in self-regulation. Recent debates have questioned whether EF and EC may in fact represent a single construct, and they have undergone scrutiny regarding construct independence. Efforts to differentiate them have further queried whether one may in fact precede the other in early childhood. In a cohort-sequential study of 191 typically developing 4-to-7 year olds (97 girls, 59.7% White), confirmatory factor analysis supported the correlated yet separable two-factor structure of EF and EC with partial scalar invariance across preschool and school-age groups. Longitudinal multi-group modeling was then used to identify predictive pathways between EF, EC, and psychopathology. For both developmental groups, EF predicted externalizing behaviors one year later while EC did not directly predict behavioral outcomes. Internalizing behaviors were found to be highly stable and predictable over time and across age; however, externalizing behaviors significantly predicted internalizing behaviors one year later in the school-age group but not the preschool group. These findings have implications for the measurement of EF and EC in early childhood, as well as the development and prediction of internalizing and externalizing behaviors across the transition to school.

Parents' use of harsh discipline and inductive discipline are theorized to change normatively across the transition from early to middle childhood (ages 5-7 years), with harsh discipline decreasing and inductive discipline increasing. Importantly, within-person support for these changes is lacking. Additionally, these changes are argued to be driven by improvements in children's cognitive and social abilities, including inhibitory control. The present study examined within-family bidirectional relations between parents' (primarily mothers') harsh discipline, inductive discipline, and children's inhibitory control across the transition to middle childhood. Participants were 118 4-, 5-, and 6-year-olds and their primary caregivers. At two time points, separated by 12 months, parents completed a questionnaire about their use of harsh and inductive discipline, and children completed a battery of inhibitory control tasks. A latent change score model was used to examine within-family bidirectional relations. More inductive discipline at Time 1 was related to a decline in harsh discipline over the year for parents of 5- and 6-year-olds, but not 4-year-olds. Harsh discipline at Time 1 was not related to change in inductive discipline. Parental discipline was not related to the change in children's inhibitory control, nor was inhibitory control related to the change in parental discipline. Relations between inductive discipline and change in harsh discipline provide within-person support for expectations of normative change in parents' discipline strategies across the transition to middle childhood. Further research examining when parents of 4-year-olds make this transition and predictors of change in parental discipline will inform research of normative trajectories of parental discipline.

Prenatal stress has a significant, but small, negative effect on children’s executive function (EF) in middle and high socioeconomic status (SES) households. Importantly, rates and severity of prenatal stress are higher and protective factors are reduced in lower SES households, suggesting prenatal stress may be particularly detrimental for children’s EF in this population. This study examined whether prenatal stress was linked to 5-year-old’s EF in a predominantly low SES sample and child sex moderated this association, as males may be more vulnerable to adverse prenatal experiences. Participants were 132 mother-child dyads drawn from a prospective prenatal cohort. Mothers reported on their depression symptoms, trait anxiety, perceived stress, everyday discrimination, and sleep quality at enrollment and once each trimester, to form a composite prenatal stress measure. Children’s EF was assessed at age 5 years using the parent-report Behavior Rating Inventory of Executive Function - Preschool (BRIEF-P) Global Executive Composite subscale and neuropsychological tasks completed by the children. Mixed models revealed higher prenatal stress was associated with lower BRIEF-P scores, indicating better EF, for females only. Higher prenatal stress was associated with lower performance on neuropsychological EF measures for both males and females. Results add to the limited evidence about prenatal stress effects on children’s EF in low SES households.

Objective: Children born very preterm (VPT; gestational age [GA] <31 weeks) have robust school readiness difficulties relative to children born full-term (FT; GA ≥37 weeks). This study examined whether four aspects of parental well-being and behavior—distress, harshness, responsiveness and positive control, and cognitive stimulation—were linked to school readiness in a sample of children born VPT <31 weeks GA and whether these characteristics similarly impact VPT and FT children.Methods: Parents of 4-year-olds born VPT (n = 55) and FT (n = 38) reported on parental distress, behavior, and cognitive stimulation. Children’s cognition, executive function, motor skills, preacademic abilities, and behavior were assessed via neuropsychological tests and parent-report questionnaires.Results: For both groups of children, higher psychological distress and harshness were associated with more behavior problems, and more cognitive stimulation was associated with higher scores on tests of cognitive, motor, and preacademic abilities. More parental distress was associated with lower cognitive ability only for children born VPT and more harshness was associated with lower preacademic skills only for children born FT.Conclusions: Identifying modifiable family factors associated with school readiness in children born VPT is essential for informing family-based interventions to improve school readiness in this population. Findings suggest that distress, harshness, and cognitive stimulation may be reasonable targets for interventions to improve school readiness in children born VPT.

This study examined the remote learning activities children born very preterm (VPT; gestational age ≤ 30 weeks) received, compared with children born full term (FT; gestational age ≥ 37 weeks), during the COVID-19 pandemic. Parents of 5- to 6-year-olds born VPT ( n = 33) and FT ( n = 33) reported on the provision, frequency, and duration of teacher-provided live instruction, educational materials, and homework; and parent-provided educational materials. More kindergarten children born VPT received small group instruction and fewer received large group instruction than FT children. Preschoolers born VPT engaged in parent-provided learning apps, educational videos, and reading activities less frequently or for shorter durations than FT children. Findings suggest that while teachers generally implemented remote learning similarly for children born VPT and FT, parents did not. Children born VPT are at higher risk for educational problems and may benefit from more intensive school- and home-based educational interventions to help offset the impact of school closures.

The aims of this study were to identify the aspects of school readiness that best distinguish very preterm (VPT) preschoolers from full-term (FT) controls, determine the extent to which readiness problems in the VPT group reflected global cognitive weaknesses or more specific deficits, and identify distinct profiles of readiness problems. Fifty-three VPT (gestational age ≤ 30 weeks) 4-year-olds were compared to 38 FT (gestational age ≥ 37 weeks) controls on measures of global cognitive ability, executive function, motor skills, early literacy and numeracy, and psychosocial functioning. Latent class analysis (LCA) was also conducted to identify individual readiness profiles. The VPT group had the most pronounced difficulties on tests of spatial and nonverbal cognitive abilities, executive function, motor skills, phonological processing, and numeracy. The VPT group also had sex-related difficulties in processing speed, social functioning, and emotion regulation. These differences were evident in analyses of both continuous scores and rates of deficits. The VPT group’s difficulties in motor skills, and VPT females’ difficulties in social functioning and emotion regulation, were evident even when controlling for global cognitive ability. LCA suggested four profiles of readiness, with the majority of the VPT group assigned to profiles characterized by relative weaknesses in either cognitive abilities or psychosocial functioning or by more global readiness problems. The findings support the need to evaluate multiple aspects of school readiness in VPT preschoolers and inform efforts to design more targeted early educational interventions.

Child genotype is an important biologically based indicator of sensitivity to the effects of parental behavior on children’s executive function (EF) in early childhood, birth to age 5. While evidence for gene × parental behavior interactions on children’s early EF is growing, researchers have called the quality of evidence provided by gene × environment interaction studies into question. For this reason, this review comprehensively examined the literature and evaluated the evidence for gene × parental behavior interactions on children’s early EF abilities. Psychology and psychiatry databases were searched for published peer-reviewed studies. A total of 18 studies met inclusion criteria. Twenty-nine of 89 (33%) examined interactions were significant. However, a p-curve analysis did not find the significant interactions to be of evidential value. A high rate of false positives, due to the continued use of candidate gene and haplotype measures of child genotype and small sample sizes, likely contributed to the high rate of significant interactions and low evidential value. The use of contemporary molecular genetic measures and larger sample sizes are necessary to advance our understanding of child genotype as a moderator of parental effects on children’s EF during early childhood and the biopsychosocial mechanisms underlying children’s EF development during this critical period. Without these changes, future research is likely to be stymied by the same limitations as current research.

Child genotype is an important biologically based individual difference conferring differential sensitivity to the effect of parental behavior. This study explored dopaminergic polygenic composite×parental behavior interactions in relation to young children’s executive function. Participants were 135 36-month-old children and their mothers drawn from a prospective cohort followed longitudinally from pregnancy. A polygenic composite was created based on the number ofCOMT, DAT1,DRD2, andDRD4alleles associated with increased reward sensitivity children carried. Maternal negative reactivity and responsiveness were coded during a series of structured mother–child interactions. Executive function was operationalized as self-control and working memory/inhibitory control. Path analysis supported a polygenic composite by negative reactivity interaction for self-control. The nature of the interaction was one of diathesis-stress, such that higher negative reactivity was associated with poorer self-control for children with higher polygenic composite scores. This result suggests that children with a higher number of alleles may be more vulnerable to the negative effect of negative reactivity. Negative reactivity may increase the risk for developing behavior problems in this population via an association with poorer self-control. Due to the small sample size, these initial findings should be treated with caution until they are replicated in a larger independent sample.

Although there is substantial evidence that socioeconomic status (SES) predicts children's executive function (EF), the mechanisms underlying this association are poorly understood. This study tested the utility of two theories proposed to link SES to children's EF: the family stress model and the family investment model. Data came from the Midwestern Infant Development Study (N = 151). To measure SES, parental education and income were assessed during pregnancy, and income was also assessed when children were 6 and 36 months old. Children's EF, operationalized as working memory/inhibitory control (WMIC) and self‐control, was assessed at 36 months of age, along with potential mediators including maternal psychological distress, harsh parenting, and cognitive stimulation. Using structural equation modeling, we tested simultaneous pathways from SES to EF: (a) via maternal psychological distress to harsh parenting (family stress model) and (b) via cognitive stimulation (family investment model). Of the SES measures, lower education predicted poorer WMIC directly and indirectly via greater maternal psychological distress. Lower education also predicted poorer self‐control via greater maternal psychological distress. This effect was partially suppressed by an indirect path from lower education to better self‐control via greater psychological distress and increased harsh parenting. Cognitive stimulation did not act as a mediator. Income was not directly or indirectly associated with EF. These findings provide partial support for the family stress model and suggest that family functioning is an important proximal mechanism for children's EF development. This study also highlights the importance of considering SES as a multidimensional construct.
