How do families help or hinder the emergence of early executive function?

Staying self-regulated in the classroom: The role of children's executive functions and situational factors

BACKGROUND

Self-regulation is crucial for children's learning and development. Several studies have explored children's inter-individual differences in self-regulation, but little is known about sources of intra-individual variation.

AIMS

This study addressed the variability of children's self-regulation across typical classroom situations and how this might be associated with children's executive functions (EFs).

SAMPLE

The study included 148 children (54.7% girls; Mage = 56.73 months).

METHODS

Self-regulation was assessed with an observational measure in teacher-led and child-led activities within naturalistic classroom settings. Children's EFs were assessed with direct assessments at the start and end of the school year.

RESULTS

Linear mixed-effect models showed that children demonstrated higher levels of self-regulation in child-led in comparison with teacher-led activities. Children with higher levels of EFs at the start of the school year showed less variation across teacher-led and child-led activities in comparison with children with lower levels of EFs. Regarding other aspects of the classroom context, neither the group size in which the activity took place nor which school subject it was focused on were associated with children's self-regulation. However, in teacher-led activities the type of interaction involved in the activity and the type of task influenced children's self-regulation.

CONCLUSION

These results suggest that children who start school with higher levels of EFs are more able to adapt to different situations, highlighting the importance of fostering these skills in early childhood. In turn, children with lower levels of EFs may need additional support from teachers to remain self-regulated across different contexts.

Linking caregiving quality during infancy to brain activity in early childhood and later executive function

There is no relationship more vital than the one a child shares with their primary caregivers early in development. Yet many children worldwide are raised in settings that lack the warmth, connection, and stimulation provided by a responsive primary caregiver. In this study, we used data from the Bucharest Early Intervention Project (BEIP), a longitudinal study of institutionally-reared and family-reared children, to test how caregiving quality during infancy is associated with average EEG power over the first 3.5 years of life in alpha, beta, and theta frequency bands, and associations with later executive function (EF) at age 8 years. The sample comprised 189 children (129 institutionally-reared; 60 family-reared) who contributed data on observed caregiving quality during infancy (baseline; average age of 22 months), resting EEG power at baseline, 30, and 42 months, and performance-based data on a series of EF tasks at 8 years. Using Bayesian estimation, observed caregiving quality at baseline was marginally linked with higher average alpha and beta power, and lower theta power, from baseline to 42 months. In turn, higher average beta power and lower average theta power were marginally associated with higher EF at 8 years. In indirect effects models, higher caregiving quality at baseline was associated with higher EF at 8 years, with a marginal indirect effect through average theta power from baseline to 42 months. Variation in the quality of the early caregiving environment may be associated with later executive function, which is partially underpinned by individual differences in brain activity during early childhood. RESEARCH HIGHLIGHTS: Examined associations between caregiving quality during infancy, brain activity during early childhood, and executive function during mid-childhood in sample of never-institutionalized and institutionally-reared children. Significant associations between higher quality caregiving during infancy and higher executive function during middle childhood. Marginal associations between caregiving quality during infancy and brain activity during early childhood. Marginal associations between brain activity during early childhood and executive function during mid-childhood.

Promoting toddlers' self-regulation and healthy eating habits among families living in poverty: A randomized controlled trial of Recipe 4 Success

The Recipe 4 Success preventive intervention targeted multiple factors critical to the health and well-being of toddlers living in poverty. This randomized controlled trial, which was embedded within Early Head Start home visits for 12 weeks, included 242 racially and ethnically diverse families (51% girls; toddler mean age = 2.58 years; data collected 2016-2019). Compared to parents in usual practice home visits, parents in Recipe 4 Success displayed greater sensitive scaffolding of toddlers' learning and more responsive food parenting practices (Cohen's d = .21-.30). Toddlers in Recipe 4 Success exhibited greater self-regulation and had healthier eating habits (Cohen's d = |.16-.35|). Results highlight the value of Recipe 4 Success in promoting parent and toddler behavior change that could have life-long benefits.

Preschool Children with Hearing Loss: Social Communication and Parenting Stress

Studies on parenting stress (PS) in parents of children with hearing loss (HL) have found relationships between child behavior, language skills and parenting stress. The role of early social communication skills has not been researched before. The aim of this cross-sectional study was to investigate the relationship between child behavior, social communication and PS. The study was performed in a subgroup of a total population sample from the AChild (Austrian Children with Hearing Impairment-Longitudinal Databank) study. Preschool children (n = 81) with all degrees of HL and average cognitive functioning and their families were included, and the Parenting Stress Index (PSI) was used. Through factor component analysis, compound scores for externalizing/internalizing problem behavior and hyperactivity were analyzed. Although mean PS was not elevated, the proportion of those with elevated scores was higher compared with the norm population. There was a strong correlation between child behavior problems and PS (strongest correlation: externalizing problem behavior r = 0.643; p < 0.001). All three problem behaviors accounted for 49.7% of the variance in PS. An indirect effect of social communication on PS was almost completely mediated by problem behavior (especially hyperactivity). The importance of social communication development with respect to problem behavior and PS is highlighted.

Systems that support hearing families with deaf children: A scoping review

BACKGROUND

Over 90% of deaf children are born to hearing parents who have limited knowledge about deafness and require comprehensive support and information to support and communicate with their deaf child. However, little is known about the systems that support hearing families with deaf children. We performed a scoping review to provide an overview of current literature on the topic.

METHODS

The protocol of the scoping review was prepared using the PRISMA statement guidelines for scoping reviews. Relevant search terms were used to identify eligible studies following discussion with the study's steering group. Databases searched were CINAHL, Medline, ProQuest Central and ASSIA, as well as grey literature from relevant journals and online sources. Included were studies published from 2000 to 2021 and available in English.

RESULTS

A search of databases identified 1274 articles. After excluding duplicates, screening titles and abstracts and full texts, 65 papers matched the identified inclusion criteria. Results included 1 RCT, 7 comparative studies, 6 literature reviews, 4 PhD theses, and 47 further empirical studies.

CONCLUSION

There is limited quality evidence on what supports hearing parents with deaf children. It is evident that further studies are needed to ensure comprehensive support is accessible and effective for hearing parents of deaf children.

The association between working memory, teacher-student relationship, and academic performance in primary school children

Introduction

Early relationships with teachers play an important role in children's development and significantly influence students' cognitive and academic performance. Studies suggest that working memory (WM) is a strong predictor of academic achievement, especially of reading and arithmetic outcomes. The associations between teacher-student relationship (TSR) quality, children's WM skills and their academic performance have been reported in numerous observational studies. However, the potentially bidirectional and temporal nature of the relationships between these constructs is understudied.

Methods

The purpose of this study was to investigate the relationships between primary school children's WM and TSR by applying a cross-lagged design and measuring these constructs at three time points throughout the academic year. More exploratively, this study investigated how WM and TSR bidirectionally relate to children's academic performance.

Results

The findings of this study revealed a temporal relationship between WM and TSR: between WM-related problems in the classroom at baseline and conflict at 3-month follow-up, and between closeness at 3-month follow-up and WM-related problems in the classroom at 5-month follow-up. Moreover, the findings showed a bidirectional relationship between arithmetic performance and WM-related problematic behaviour.

Discussion

This study highlights that relationships between the teacher and students play an important role in supporting students' cognitive and academic development. Importantly, this study suggests that children with WM problems may benefit from interventions that focus on improving their relationships with teachers. Additionally, the findings propose that interventions targeting WM may also have positive effects on children's academic performance.

Does the Frontal Brain Electrical Activity Mediate the Effect of Home Executive Function Environment and Screen Time on Children's Executive Function?

Executive functions play an important role in various developmental aspects of children; however, environmental factors influencing individual differences in children's executive function and their neural substructures, particularly in middle childhood, are rarely investigated. Therefore, the current study aimed to investigate the relationship between the home executive function environment (HEFE) and screen time with the executive function of children aged 8-12 years by employing the mediating variables of alpha, beta, and theta waves. The parents of 133 normal children completed Barkley Deficits in Executive Functioning, HEFE, and Screen Time Scales. Alpha, beta, and theta brain waves were also measured. Data were examined using correlational and path analysis. The results suggested a positive and significant relationship between home executive functions and the executive functions of children. Furthermore, the results indicated an inverse and significant relationship between screen time and executive function. The results also proved the mediating role of alpha, beta, and theta brain waves in the relationship between screen time and the children's executive function. Environmental factors (such as home environment and screen time) affect the function of brain waves and, thus, the daily executive function of children.

Does parental autonomy support mediate the relation between parent and infant executive function? A study of mothers and fathers in the Netherlands and China

Parenting skills, such as Autonomy Support (AS), have been proposed as a potential mechanism explaining the intergenerational contiguity of Executive Function (EF). However, few studies have focused on mothers and fathers among non-Western families. The current study investigated the role of maternal and paternal AS in the relation between parental EF and infant EF at 14 months of age among 123 Dutch and 63 Chinese first-time mothers and fathers and their infants. Multiple-group structural equation models were built for mothers and fathers separately with country as a grouping variable. Results showed that parental AS did not mediate the relation between parent EF and infant EF at 14 months. Mean-level differences were found in parental AS, maternal EF, and infant inhibition across countries, while no country differences were found in the relation between parent EF, AS and infant EF. Our findings suggested that individual differences in early EF may not be stable enough to be reliably predicted from parental factors across the Netherlands and China.

Advancing Educational Research on Children’s Self-Regulation With Observational Measures

Self-regulation is crucial for children’s development and learning. Almost by convention, it is assumed that self-regulation is a relatively stable skill, and little is known about its dynamic nature and context dependency. Traditional measurement approaches such as single direct assessments and adult reports are not well suited to address questions around variations of self-regulation within individuals and influences from social-contextual factors. Measures relying on child observations are uniquely positioned to address these questions and to advance the field by shedding light on self-regulatory variability and incremental growth. In this paper, we review traditional measurement approaches (direct assessments and adult reports) and recently developed observational measures. We discuss which questions observational measures are best suited to address and why traditional measurement approaches fall short. Finally, we share lessons learned based on our experiences using child observations in educational settings and discuss how measurement approaches should be carefully aligned to the research questions.

[Formula: see text]Parental interaction style, child engagement, and emerging executive function in fetal alcohol spectrum disorders (FASD)

Children with fetal alcohol spectrum disorders (FASD) are known to experience cognitive and neurobehavioral difficulties, including in areas of executive function and social skills development. Interventions for these challenges have focused on a number of areas, including parent-based training. Despite the general consensus that specific parenting styles consistent with an "authoritative" - warm but firm - parenting approach may influence behavioral self-regulation, it is not known what specific parental interaction styles are associated with child engagement and emerging executive function in this population. The current study used an observation-based behavioral coding scheme during parent-child play interactions and associated parent report-based executive function measures in children with FASD. Here, we demonstrate that parental interaction styles with increased responsive/child-oriented behavior and parental affect are associated with higher levels of child play engagement, while parental interaction that has increased achievement-orientation is associated with higher levels of emerging executive function in children with FASD. These findings help inform future studies on behavioral targets in parent-based training programs and highlight the importance of considering certain parental interaction styles during parent-child play.

Effects of Maternal and Child Lifetime Traumatic Stress Exposures, Infant Temperament, and Caregiving Quality on Preschoolers' Executive Functioning

We examined effects of maternal and child lifetime traumatic stress exposures, infant temperament, and caregiving quality on parent ratings of preschoolers' executive functioning (EF). Maternal lifetime trauma was associated with preschoolers' EF problems; this association was mediated by greater child trauma exposure. Infant temperament was associated with EF abilities, particularly among females. Among males, infant extraversion/surgency mediated the association of maternal lifetime trauma with poorer child EF. Caregiving quality was negatively associated with maternal and child trauma exposures but did not predict child EF. Findings have implications for interventions to identify children at risk for poor EF and optimize outcomes.

Relationships between Depression and Executive Functioning in Adolescents: The Moderating Role of Unpredictable Home Environment

Although researchers have explored the link between depression and executive functioning (EF), the influence of early-life environmental and relational instability on this association has not been comprehensively assessed in adolescents. This cross-sectional study examined whether unpredictability of home environment in childhood moderated the relationship between depression and EF in adolescents. Participants were 138 adolescents aged 13 to 17 years (72% female; 47.8% White; 47.1% Hispanic). Diagnostic status (major depression versus healthy control) and depression severity were assessed using psycho-diagnostic interviews and self-reports from parents and adolescents. Participants also completed the Questionnaire of Unpredictability in Childhood (QUIC). EF was assessed using self-report (Behavior Rating Inventory of Executive Function, Second Edition; BRIEF2) and a battery of performance-based measures. Results showed that QUIC scores moderated the relationship between depression and BRIEF2 scores, such that high unpredictability was associated with poorer EF for adolescents exhibiting low depression severity. Participants with the highest levels of depression exhibited the poorest EF ratings, regardless of childhood unpredictability. Unpredictability was moderately associated with performance-based measures, but did not interact with depressive symptoms to predict complex performance-based EF. Recommendations include assessing for unpredictable childhood environment and acknowledging this risk factor for poor EF in youth with sub-threshold depression. Treatment implications are discussed with respect to family systems/parenting interventions, as mildly depressed adolescents growing up in unstable homes may be vulnerable to EF difficulties. Further, this study adds to the EF measurement literature by examining associations between self-report and performance-based EF instruments in a diverse sample of adolescents.

Relationships Among Maternal Interactive Behaviors, Preschoolers’ Hot and Cool Executive Function, and Conscience

Objectives: Preschoolers’ conscience refers to a concept revolving around moral emotion, cognition and behavior. This study investigates the relationships among preschoolers’ conscience, hot and cool executive function, and maternal interactive behaviors. Furthermore, it examines the mediating role of preschoolers’ executive function in the relationship between maternal interactive behaviors and preschoolers’ conscience.Methods: Participants comprised 220 mothers and teachers engaging with preschoolers. Data were collected during the COVID-19 period. Therefore, a research process, which suited the changing operations of day-care centers and kindergartens due to social distancing, was adopted. The mothers answered questionnaires on preschoolers’ conscience and maternal interactive behaviors, and the teachers on hot and cool executive function. Obtained data were analyzed using correlations, multiple regression, hierarchical regression, and bootstrapping.Results: Results revealed that the preschoolers’ conscience was significantly related to maternal interactive behaviors and preschoolers’ hot and cool executive function. The preschoolers’ executive function mediated the effect of maternal interactive behaviors on their conscience. Specifically, the plannning and organizing of the executive function fully mediated the relationship between maternal efficient interactive behaviors and preschoolers’ internalized conduct. The bootstrapping result suggested that the indirect effect is statistically significant.Conclusion: This study explored an area of morality that is less researched and incorporated the importance of executive function into it. Additionally, the results confirmed the mediating effect of preschoolers’ executive function on their conscience. The results obtained are expected to help organize activities for developing morality.

Assessing the validity and reliability and establishing norm values for a selective attention test in a Turkish sample of 6–14-year-old participants

Selective attention is a cognitive skill that allows an individual to focus on a particular input for further processing while simultaneously suppressing irrelevant or distracting information. In this study, we have developed a new test to assess selective attention-the Cognitive Skills Assessment of Minerva (CSM) Selective Attention Test-and have established selective attention norm values for Turkish individuals aged 6-14 years. This new online selective attention assessment test includes the flanker task. We employed split-half reliability to prove the reliability of the test. Based on the analysis, there was no significant difference between the groups, indicating that the test is reliable. We used criterion-related validity (congruent validity) analysis to evaluate the CSM Selective Attention Test. The correlation between the results of the new test and the Eriksen Flanker Test showed that the new test is valid. Finally, we conducted a comprehensive norm study with 2,297 participants aged 6-14 years from 12 different regions and schools in Turkey. According to the analysis of variance, age but not gender is a distinguishing factor for selective attention. We subsequently established norm values for each age group. The findings also show that the CSM Selective Attention Test provides reliable results across all samples and populations aged 6-14.

A Hierarchical Integrated Model of Self-Regulation

We present a hierarchical integrated model of self-regulation in which executive function is the cognitive component of the model, together with emotional, behavioral, physiological, and genetic components. These five components in the model are reciprocally and recursively related. The model is supported by empirical evidence, primarily from a single longitudinal study with good measurement at each level of the model. We also find that the model is consistent with current thinking on related topics such as cybernetic theory, the theory of allostasis and allostatic load, and the theory of skill development in harsh and unpredictable environments, referred to as “hidden talents.” Next, we present literature that the integrative processes are susceptible to environmental adversity, poverty-related risk in particular, while positive social interactions with caregivers (e.g., maternal sensitivity) would promote self-regulatory processes or mitigate the adverse effect of early risk on the processes. A hierarchical integrative model of self-regulation advances our understanding of self-regulatory processes. Future research may consider broader social contexts of the integrative self-regulation system, such as neighborhood/community contexts and structural racism. This can be an integral step to provide children with equitable opportunities to thrive, even among children living in socioeconomically and psychosocially disadvantaged environments.

Chaos during the COVID-19 outbreak: Predictors of household chaos among low-income families during a pandemic

OBJECTIVE

The objective of this study was to explore whether household chaos measured during the COVID-19 pandemic is predicted by prepandemic parental and household characteristics.

BACKGROUND

The COVID-19 pandemic has dramatically altered children's home environments and routines due to stay-at-home orders, school closures, and economic shocks. These disruptions have been especially challenging for low-income families who have limited resources and have been disproportionately affected by the pandemic. Household chaos, which captures routines, organization, stability, noise, and crowding in the home, is a documented threat to parent functioning and positive child development. The pandemic has likely exacerbated household chaos, especially for low-income families.

METHOD

Data come from a larger, ongoing study of low-income children and their parents in Tulsa, Oklahoma; this analysis relies on data from the subset of low-income parents who responded to surveys when their children were in kindergarten (in 2018-2019) and during the pandemic, when their children were in first grade (n = 335). We use multivariate ordinary least squares regression models to test whether household chaos measured during the pandemic is predicted by prepandemic parental and household characteristics.

RESULTS

Prepandemic parental depression and household chaos were significantly predictive of chaos during the pandemic, even after accounting for household demographics.

IMPLICATIONS

The current study highlights pandemic-induced elevations in parental distress and household chaos among low-income families. Results will provide valuable direction to policymakers, educators, and parents on how best to offset negative impacts of the COVID-19 pandemic on family functioning and child development.

Maternal education and Siblings: Agents of cognitive development in kindergarten

In this study (n = 1000, M_{age at K1entry} = 53.4 months, SD = 3.4; 53% females), we investigated the contributions of the family socioeconomic status (SES; maternal education and an income-related measure) and number and age of siblings to the development of children's math, reading, and working memory (WM) updating skills over the kindergarten years. Results from a multivariate multilevel growth curve model showed that children from more disadvantaged SES backgrounds already had a multifaceted developmental lag at kindergarten entry. Maternal education was the aspect of SES that more clearly affected the child's cognitive development; the mother's education predicted children's math, reading, and WM-Updating skills at kindergarten entry as well as the rate of development of reading skills over the kindergarten years. Independently of SES status, children with more siblings also showed poorer reading and math skills than those in one-child families at kindergarten entry. We also found that both older and younger siblings affected, negatively, children's reading skills before they attended kindergarten-which suggests that the development of reading skills is more responsive to environmental factors during the first years than other aspects of the child development. The findings underscore the independent role of siblings upon entry to kindergarten, and the enduring role of maternal education even after children are exposed to formal schooling.

The Impact of Household Chaos and Dietary Intake on Executive Function in Young Children

Children's executive functions (EFs) emerge over time and can be shaped by household environments and dietary intake. However, there is a lack of knowledge about how these factors influence EFs in children aged 18-24 months. This study tested a model exploring the relations between parent-reported dietary intake, household chaos, and child EF. The sample consisted of 294 families participating in the STRONG Kids2 birth cohort study of nutrition and child health. Caregivers completed the Food Frequency Questionnaire (FFQ), the Confusion, Hubbub, and Order Scale (CHAOS), and the Behavior Rating Inventory of Executive Function^®-Preschool Version (BRIEF-P) to assess model variables. Regression analyses revealed a significant and independent association between assorted snacks and processed foods and two EF subscales. There were also significant associations between household chaos and each EF subscale. There was no significant moderation effect. These findings suggest that family households characterized by dysregulation are associated with children's EF difficulties during early childhood and that the role of unhealthy dietary intake in child EF should be explored further. Future longitudinal studies that include multi-method approaches are needed to document the mechanisms through which household chaos impacts child EF over time.

The role of infant attention and parental sensitivity in infant cognitive development in the Netherlands and China

Infant attention and parental sensitivity are important predictors of later child executive function (EF). However, most studies have investigated infant and parent factors in relation to child EF separately and included only mothers from Western samples. The current study examined whether both infant attention at 4 months and parental sensitivity at 4 and 14 months were related to infant EF (i.e., inhibition, working memory, and cognitive flexibility) at 14 months among 124 Dutch and 63 Chinese first-time mothers and fathers and their infants. Findings revealed that parental sensitivity at 4 months was not correlated with infant EF abilities at 14 months. However, infant attention at 4 months was significantly related to 14-month working memory, but not to inhibition and cognitive flexibility. Maternal sensitivity at 14 months was significantly related to 14-month inhibition, but not to working memory and cognitive flexibility). No country differences were found in the relation among 4-month infant attention, parental sensitivity, and EF outcomes. Results show that both infant and parent factors are associated with early EF development and that these correlates of early EF skills may be similar in Western and non-Western samples.

Prenatal mother-father cortisol linkage predicts infant executive functions at 24 months

The present study investigated associations between prenatal mother-father cortisol linkage and infant executive functions. Data come from an international sample (N = 358) of predominantly white and middle- to upper-class first-time parents. During late pregnancy, parents collected diurnal salivary cortisol samples and reported on levels of psychological stress. At 24 months, children completed a battery of executive function tasks. Parent cortisol linkage was operationalized as the time-dependent, within-dyad association between maternal and paternal diurnal cortisol. Results indicated that prenatal linkage was positively related to infant executive functions, suggesting that stronger mother-father cortisol linkage was associated with higher executive function scores. Additionally, this relation was moderated by paternal average cortisol levels such that executive function scores were lower when fathers had higher average cortisol levels and linkage was weak. This association suggests that elevated paternal cortisol amplifies the negative relation between lower cortisol linkage and lower infant executive function scores. Importantly, these findings were observed while controlling for observational measures of caregiving and self-report measures of psychosocial functioning and infant social-emotional behavior. These results suggest that prenatal linkage of mother's and father's stress physiology plays a potentially important part in programming and regulating infant neurocognitive development.

Effects of household chaos and parental responsiveness on child executive functions: a novel, multi-method approach

Background

Executive functions can be adversely affected by contextual risks in the home environment including chaos and parenting challenges. Furthermore, household chaos negatively influences parenting practices. Few studies, however, have examined the role of parenting in the association between household chaos and child executive functions.

Methods

Using a sample of 128 school-aged children (mean = 61.9 months, SD = 2.0, range 58–68 months) and their mothers, the present study examined direct and indirect effects (via parental responsiveness) of household chaos on child executive functioning. Multi-measures were used including performance-based assessments, behavioural observations, questionnaires, and video-home tours.

Results

Household chaos had both a direct effect on child executive functions (β = − .31, 95% CI [− .58, − .04]) and an indirect effect (β = − .05, 95% [− .13, − .01]) via parental responsiveness. Further, the indirect effect was only significant for household instability.

Conclusion

These findings indicate that parental responsiveness may be compromised by household chaos, with implications for the executive functions of school-aged children. Preventative strategies are needed to improve the stability in the home and strengthen parenting practices.

Contributions of Parenting Quality and Coparenting Relationship Quality to the Development of Child Executive Functioning

Executive functioning (EF) skills contribute positively to mental and physical health across the lifespan. High-quality parenting is associated with better child EF. However, research has largely focused on the contributions of mothers' parenting and failed to apply a family systems perspective to more comprehensively consider the consequences of parenting quality and coparenting relationship quality for the development of children's EF. This study examined the independent and joint contributions of mothers' observed parenting, fathers' observed parenting, and supportive coparenting during infancy to children's attention in toddlerhood (26 months) and aspects of EF (i.e., inhibitory control and impulsivity) at 7.5 years of age. Data came from a study of 166 families who participated in a larger longitudinal study. Assessments were conducted at 9-months postpartum (n = 158), 26-months postpartum (n = 114), and when children were 7.5 years of age (n = 100). Results indicated statistically significant associations between fathers' parenting quality at 9-months postpartum and greater child inhibitory control at 7.5 years of age. Mothers' parenting quality at 9-months postpartum was associated with better child attention in toddlerhood. Supportive coparenting was not directly associated with toddler or child EF. However, supportive coparenting moderated the association between fathers' parenting quality and child impulsivity, such that the adjusted effect of fathers' parenting on child impulsivity was negative when supportive coparenting was high. Findings highlight the importance of considering the development of child EF within a family systems framework.

The interplay between early social interaction, language and executive function development in deaf and hearing infants

In this article, we review the influence of early social interaction on the development of executive function and language in infants. We first define social interaction, executive function and language and show how they are related in infant development. Studies of children born deaf are used to illustrate this connection because they represent cases where there has been a disruption to early social interaction and the development of intersubjectivity. Unlike other groups, the disturbance to development is known to be largely environmental rather than neuro-biological. This enables us to more accurately tease apart those impacts on EF that are associated with social interaction and language, since the potential confounds of disordered cognitive development are largely controlled for. The review offers a unifying model for how social, cognitive and linguistic development work together in early human development.

Home Language Environment and Executive Functions in Mexican American and Chinese American Preschoolers in Head Start

Research Findings

Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46) or Chinese American (CA, N = 44) low-income families enrolled in Head Start preschool programs, parents reported on their HLE (home language balance, home English/heritage language activities) and children's EF (inhibitory control and attention shifting) was measured by cognitive tasks. Findings showed preschool-aged DLLs in low-income immigrant families received more heritage language exposure relative to English language exposure at home. Several demographic variables (parental education, per capita income, DLL group, child age of English acquisition, child generation, child English receptive vocabulary) were related to various aspects of HLE. Controlling for covariates, the amount of heritage language activities at home was uniquely and positively related to children's attention shifting.

Practice or Policy

The findings underscore the importance of incorporating language background considerations when designing intervention programs that target HLE and EF in low-income DLLs.

Dogs' insensitivity to scaffolding behaviour in an A-not-B task provides support for the theory of natural pedagogy

Executive function plays a critical role in regulating behaviour. Behaviour which directs attention towards the correct solution leads to increased executive function performance in children, but it is unknown how other animals respond to such scaffolding behaviour. Dogs were presented with an A-not-B detour task. After learning to go through gap A to obtain the reward, the barrier was reversed, and the dogs had to inhibit their learned response and enter through gap B on the opposite side. Failure to do so is known as the perseveration error. In test trials, dogs taking part in one of two scaffolding conditions, a pointing condition, where the experimenter pointed to the new gap, and a demonstration condition, where the experimenter demonstrated the new route, were no less likely to commit the perseveration error than dogs in a control condition with no scaffolding behaviour. Dogs' lack of responsiveness to scaffolding behaviour provides little support for suggestions that simple social learning mechanisms explains scaffolding behaviour in humans. Instead, our results suggest that the theory of natural pedagogy extends to the development of executive function in humans. This suggests that human children's predisposition to interpret ostensive-communicative cues as informative may be an innate, species-specific adaptation.

Parents' Views on Play and the Goal of Early Childhood Education in Relation to Children's Home Activity and Executive Functions: A Cross-Cultural Investigation

The present study investigated the cross-cultural variations in parents' views on the role of play in child development and the primary purpose of preschool education from Ethiopia and Hungary. It also examined the cross-cultural variations in preschoolers' executive functions (EF), the frequency of their engagement in home activities, and the role of these activities in the development of EF skills. Participants included 266 preschoolers (Ethiopia: 139 of which 44.6% boys; M _age = 63.83 months; SD = 7.68 months; Hungary: 127 of which 48% boys; M _age = 62.06 months; SD = 9.37 months) with their parents (Ethiopia: 45.32% male; M_age = 36.66 years; SD = 7.14 years; Hungary: 13.18% male; M _age = 37.71 years; SD = 5.97 years). The independent samples t-test showed that Ethiopian parents view fostering academic skills for preschooler significantly more important than their Hungarian counterparts do. We also found that while Ethiopian parents hold the belief that academic and cognitive development is the major purpose of preschool education, Hungarian prioritize social-emotional development and entertainment. Additionally, preschoolers in Ethiopia were reported to engage in academic and arts and crafts activities after preschool significantly more frequently than their Hungarian counterparts. On the contrary, preschoolers in Hungary were found to engage in fine-motor activities, solitary play, sports and other physical activities significantly more frequently than their Ethiopian counterparts. No significant differences were found in EF skills between preschoolers from Ethiopia and Hungary. Results from hierarchical regression analyses showed that, after accounting for age and SES, preschoolers' frequency of pretend play and their parents' play support beliefs were found to be small to medium-sized predictors of inhibitory control skills in both samples. However, children's frequency of having breakfast at home was another significant predictor in the Ethiopian sample only. The frequency of participation in arts and crafts and other fine-motor activities were found to be important predictors of preschoolers' visual-spatial working memory skills in the Ethiopian and the Hungarian samples, respectively. We also found that, after controlling for SES, parental play support was an important factor associated with preschoolers' shifting skills only in the Hungarian sample. Based on the findings, we made important conclusions.

Household Chaos, Parental Responses to Emotion, and Child Emotion Regulation in Middle Childhood

Parents' responses to children's negative emotional states play a key role in the socialization of emotion regulation skills in childhood. Much of the prior research on child ER has focused on early development using cross-sectional designs. The current study addresses these gaps by using a longitudinal design to examine individual differences of ER at two times points in middle childhood. We examined the development of children's ER by testing hypotheses about the interplay of parent response to emotions and household chaos in the prediction of individual differences in children's ER. Participants were the mothers of children at 6 and 9 years of age among 224 families in a socioeconomically diverse sample that was part of an ongoing longitudinal study. Mothers completed questionnaires regarding themselves, their children, and their home environment. Mothers' reports of better child ER at both time points were positively associated with mothers' more supportive responses and negatively associated with mothers' less non-supportive responses, as well as lower household chaos. Chaos statistically moderated the link between non-supportive parental responses to emotion and child ER, but only at 6 years of age. The strength of the link between child ER and non-supportive parental responses to emotions was strong only at lower levels of household chaos. At the beginning of middle childhood, family processes linking parent responses to child emotions and children's developing ER may not function at higher levels of household chaos.

Patterns of growth in executive functioning during school years: Contributions of early mother-child attachment security and maternal autonomy support

Executive functioning (EF) undergoes marked developmental improvements during the early school years. Given the crucial role of EF in learning and school adjustment, it is important to document the factors that bolster the development of executive competence, especially during a period of growth. Although substantial evidence suggests that parent-child relationships relate to EF, few longitudinal studies have examined the parental antecedents of EF developmental trajectories during the school years. Accordingly, this multiyear longitudinal study (N = 102) explored the respective roles of early mother-child attachment security and maternal autonomy support in the prediction of patterns of growth in working memory, cognitive flexibility, and planning skills across Grades 2 to 4. Multilevel growth curve analyses revealed a unique positive relation between attachment security and all EF skills, whereas autonomy support was mainly independently associated with initial planning performance. These findings provide further suggestion for a global contribution of secure attachment relationships to children's executive competence and highlight the importance of supporting children's autonomy to foster the emergence of more complex EF abilities such as planning. This study also supports the relevance of considering multiple aspects of parent-child relationships to delineate how early caregiving experiences contribute to children's EF development.

An East-West contrast in executive function: Measurement invariance of computerized tasks in school-aged children and adolescents

Existing cross-cultural findings related to school-aged children's executive function (EF) from studies using computerized tasks highlight both an East-West contrast (East > West) and potential methodological confounds (e.g., contrasting levels of computer fluency). Capitalizing on two recent data sets, this multisite study of 1,311 children living in mainland China (n = 453; M_age = 11.89 years, SD = 0.87), Hong Kong (n = 371; M_age = 12.21 years, SD = 0.99), and the United Kingdom (n = 487; M_age = 11.91 years, SD = 0.93) tested measurement invariance of a computerized EF-task battery prior to investigating cultural contrasts in mean levels of EF efficiency scores. Our models established partial scalar invariance across sites. Latent factor means were substantially lower for British children than for their counterparts from either mainland China or Hong Kong, with a significant but smaller contrast between the latter two groups. Within the Chinese sample, self-reported computer use was unrelated to variation in children's performance on online tests of EF, indicating that peripheral effects of task modality are unlikely to explain the between-culture differences in EF task performance.

Associations between Subjective and Objective Measures of the Community Food Environment and Executive Function in Early Childhood

The present study utilized a cross-sectional design to assess whether two indicators of the community food environment, parent perceptions of the community food environment (i.e., as assessed by parent reports of access to, availability, and affordability of foods) and limited food access (via census data), were related to executive function in preschool children. Children were recruited during the 2014–2015 academic year from Head Start and community-based preschools (N = 102) and children’s executive function ability was tested using the Head–Toes–Knees–Shoulders task. Multiple linear regression analysis was used, as well as adjusted standard errors to account for clustering at the classroom level. Parent reports of their food environment were significantly related to children’s executive function, such that children living in higher quality community food environments had better executive function. In contrast, limited food access using census data was not significantly related to executive function. The results suggest that parent reports of the community food environment in early childhood may contribute to young children’s cognitive outcomes more so than being in a limited food access area, as these data may not represent individual behaviors or capture the variability of the accessibility and affordability of healthy foods. Policy makers should consider correlations between the food environment and early executive functioning when developing new community health/wellness legislation.

Characteristic Executive Dysfunction for High-Functioning Autism Sustained to Adulthood

The comprehensiveness and severity of executive dysfunction in high-functioning autism (HFA) spectrum disorder have not reached a unified conclusion especially in patients in adulthood. Clarifying this issue is critical for guiding clinical diagnosis and targeted intervention. The primary objective of the present meta-analysis was to study the characteristics of executive function (EF) in adults with HFA compared to typically developing (TD) adults, by taking five key components into consideration, including inhibition, working memory, flexibility, planning, and fluency. The PubMed and Embase databases were searched to identify peer-reviewed studies that compared EF in adults with and without HFA from 1980 to November 2018. Hedges' g effect sizes were computed to measure the primary outcome. Moderators like age, sex, and diagnostic tools were controlled using meta-regressions. Forty-two studies satisfying the selection criteria were included, which resulted in a large sample size of 2419 participants. A moderate overall effect size for reduced EF across domains was found in adults with HFA, compared with TD (g = 0.57, 95% confidence interval 0.47-0.66). Subsequently, a broad executive dysfunction was found in adults with HFA in this study (flexibility [g = 0.69], planning [g = 0.64], inhibition [g = 0.61], working memory [g = 0.48], fluency [g = 0.42]), with the predominated impairment on flexibility and planning. Taken together, these results provide evidence for the executive dysfunction hypothesis and may assist in the clinical diagnosis and targeted intervention, suggesting the necessity of sustained intervention on EF for individuals with HFA from childhood to adulthood. LAY SUMMARY: The meta-analysis explored the characteristics of EF in adults with high-functioning autism (HFA) comparing to typically developing controls. Moderate effect sizes for reduced EF across domains were found in adults with HFA, with the flexibility and planning being the most predominately impaired. A comprehensive measurement of EF in adults with HFA has important clinical implications for the diagnosis, treatment, prognosis, and a fundamental understanding for developmental trajectory of these patients.

The Role of Executive Functions in Socioeconomic Attainment Gaps: Results From a Randomized Controlled Trial

The socioeconomic attainment gap in mathematics starts early and increases over time. This study aimed to examine why this gap exists. Four-year-olds from diverse backgrounds were randomly allocated to a brief intervention designed to improve executive functions (N = 87) or to an active control group (N = 88). The study was preregistered and followed CONSORT guidelines. Executive functions and mathematical skills were measured at baseline, 1 week, 3 months, 6 months, and 1 year posttraining. Executive functions mediated the relation between socioeconomic status and mathematical skills. Children improved over training, but this did not transfer to untrained executive functions or mathematics. Executive functions may explain socioeconomic attainment gaps, but cognitive training directly targeting executive functions is not an effective way to narrow this gap.

Perception of Caregiving During Childhood is Related to Later Executive Functions and Antisocial Behavior in At-Risk Boys

Executive functions are considered essential for effective navigation in the social world. Parental responsiveness is a critical ingredient for normative social development and, as such, may be connected with the development of executive functions. Disruption of this development may, in turn, lead to maladaptive and antisocial behaviors. The purpose of this study was to evaluate the nature of the connections among perceived patterns of caregiving experienced in childhood, executive functions, and antisocial behaviors in at-risk adolescents. Seventy-one adolescent boys were recruited from two high-schools for adolescents who were not deemed suitable for regular schooling due to behavioral and emotional issues. Executive functions were tested using a computer-administered neuropsychological battery (CANTAB), and maternal parenting experiences and antisocial behaviors were assessed using retrospective and current questionnaires. Structural equation modeling (SEM) approach was employed to examine whether executive functions mediated the relationship between children's perceived patterns of maternal care and subsequent development of antisocial behaviors. Although maternal care had a significant direct effect on executive function (standardized coefficient = .49, p = .03) and antisocial behavior (standardized coefficient = .53, p = .05), SEM demonstrated no mediating relationships among these variables. Instead, maternal care predicted unique variance in both executive functions (standardized coefficient = .61, p = .02) and antisocial behavior (standardized coefficient = .51, p = .05). This study suggests a link between the experience of childhood caregiving and adolescent executive functions and delinquency and highlights the importance of early parenting interventions to aid executive function development. Such early interventions could potentially enhance long-term pro-social behavior.

Parenting and Children's Executive Function Stability Across the Transition to School

When children transition to school between the ages of 4 and 6 years, they must learn to control their attention and behavior to be successful. Concurrently, executive function (EF) is an important skill undergoing significant development in childhood. To understand changes occurring during this period, we examined the role of parenting in the development of children's EF from 4 to 6 years old. Participants were mother and child dyads (N = 151). Children completed cognitive tasks to assess overall EF at age 4 and age 6. At both time points, mothers and children completed interaction tasks which were videotaped and coded to assess various parenting dimensions. Results indicated that children with high EF at age 4 were more likely to have high EF at age 6. In addition, results suggested that higher levels of positive parenting across the transition to school promote stability of individual differences in EF.

Improvement of Planning Skills in Children With Autism Spectrum Disorder After an Educational Intervention: A Study From a Mixed Methods Approach

The literature confirms that individuals with autism spectrum disorder (ASD) have planning deficits. However, few interventions have targeted these deficits. The aims of this study were to: (1) show that the mixed methods approach can be useful in studying planning skills of children with ASD during and after an educational intervention; (2) assess whether the planning skills of two groups of children with ASD improved during the intervention and if this progress was maintained 1 month after completing the intervention. The groups were formed depending on each child’s severity level (SL) of ASD according to DSM-5: SL1 (requiring support) and SL2 (requiring substantial support). Each group was composed of four children. In the framework of mixed methods, we used observational methodology, which is considered as mixed methods in itself because it integrates qualitative and quantitative elements. A nomothetic/follow-up/multidimensional observational design was used. Planning skills manifested by children during the intervention were codified, as well as the scaffolding behaviors provided by the educational specialist. These skills and behaviors were also coded in one session, which took place 1 month after the intervention. Coded data of each group were submitted to prospective and retrospective lag sequential analysis. This informed of the sequential structure of planning skills performed by children in interaction with the educational specialist at the beginning and at the end of the intervention, as well as 1 month later after the intervention. The comparison of the patterns obtained in these three temporal moments allowed us to know the improvement of the two groups in the use of planning skills. Results showed that both groups improved their autonomous use of planning skills. However, SL1 group used successfully and autonomously complex planning skills, while SL2 group were unable to achieve this gain. SL2 group progressed in autonomy, but only using basic planning skills. Both groups can further improve their use of planning skills; therefore, the intervention should be adjusted to their characteristics and temporarily extended. These findings contribute to the, as yet, little studied field of intervention and assessment of planning skills in children with ASD using a mixed methods approach.

Comparing Executive Functioning in Children and Adolescents With Fetal Alcohol Spectrum Disorders and ADHD: A Meta-Analysis

Objective: Fetal alcohol spectrum disorders (FASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are associated with a range of neurocognitive impairments. Executive functioning deficits are a hallmark feature of both disorders. Method: The present meta-analysis was undertaken to disentangle the behavioral phenotype of FASD and ADHD by quantitatively differentiating executive functioning differences between these two groups. The current meta-analysis reviews 15 studies comparing children and adolescents with FASD and ADHD to typically developing (TD) samples, on a variety of executive function measures. Results: Results indicate that when compared with TD samples, FASD and ADHD samples demonstrate significant executive function deficits (d = 0.82 and d = 0.55, respectively). In addition, FASD samples experience significantly greater deficits when compared with ADHD samples (d = 0.25). Results were moderated by IQ and socioeconomic status. Conclusion: These findings further our understanding of the cognitive differences between FASD and ADHD samples and have the potential to influence future basic research, assessment, and intervention.

Enhancing Executive Functions Through Social Interactions: Causal Evidence Using a Cross-Species Model

It has long been theorized that humans develop higher mental functions, such as executive functions (EFs), within the context of interpersonal interactions and social relationships. Various components of social interactions, such as interpersonal communication, perspective taking, and conforming/adhering to social rules, may create important (and perhaps even necessary) opportunities for the acquisition and continued practice of EF skills. Furthermore, positive and stable relationships facilitate the development and maintenance of EFs across the lifespan. However, experimental studies investigating the extent to which social experiences contribute causally to the development of EFs are lacking. Here, we present experimental evidence that social experiences and the acquisition of social skills influence the development of EFs. Specifically, using a rat model, we demonstrate that following exposure to early-life adversity, a socialization intervention causally improves working memory in peri-adolescence. Our findings combined with the broader literature promote the importance of cultivating social skills in support of EF development and maintenance across the lifespan. Additionally, cross-species research will provide insight into causal mechanisms by which social experiences influence cognitive development and contribute to the development of biologically sensitive interventions.

Maternal Language and Child Vocabulary Mediate Relations Between Socioeconomic Status and Executive Function During Early Childhood

This article examined longitudinal relations among socioeconomic risk, maternal language input, child vocabulary, and child executive function (EF) in a large sample (N = 1,009) recruited for a prospective longitudinal study. Two measures of maternal language input derived from a parent-child picture book task, vocabulary diversity (VOCD), and language complexity, showed variation by socioeconomic risk at child ages 15, 24, and 36 months. Maternal VOCD at child age 24 months and maternal language complexity at child age 36 months mediated the relation between socioeconomic risk and 48-month child EF, independent of parenting sensitivity. Moreover, 36-month child vocabulary mediated the relation between maternal language input and child EF. These findings provide novel evidence about mechanisms linking socioeconomic risk and child executive function.

The role of the visual association cortex in scaffolding prefrontal cortex development: A novel mechanism linking socioeconomic status and executive function

Socioeconomic status (SES) is associated with executive function (EF) and prefrontal cortex (PFC) development. However, understanding of the specific aspects of SES that influence development of EF and the PFC remains limited. We briefly review existing literature on proposed mechanisms linking SES with EF. Then, we present a novel conceptual model arguing that early cognitive stimulation shapes EF and PFC development. We propose that cognitive stimulation drives lower-level sensory and perceptual processes that may impact EF and PFC development through reciprocal connections between the ventral visual stream and PFC. We argue that caregivers guide attention and associative learning, which provides children the opportunity to regulate attention and gain semantic knowledge. This experience in turn allows for opportunities to train the PFC to resolve conflict between stimuli with overlapping features and engage in increasingly complex computations as visual processing systems develop; this may lay the groundwork for development of EF. We review existing evidence for this model and end by highlighting how this conceptual model could launch future research questions.

Executive functions are cognitive gadgets

Many psychologists and neuroscientists still see executive functions as independent, domain-general, supervisory functions that are often dissociated from more "low-level" associative learning. Here, we suggest that executive functions very much build on associative learning, and argue that executive functions might be better understood as culture-sensitive cognitive gadgets, rather than as ready-made cognitive instincts.

Clinical and cost-effectiveness of teen online problem-solving for adolescents who have survived an acquired brain injury in the UK: protocol for a randomised, controlled feasibility study (TOPS-UK)

INTRODUCTION

Paediatric acquired brain injury is a leading cause of mortality in children in the UK. Improved treatment during the acute phase has led to increased survival rates, although with life-long morbidity in terms of social and emotional functioning. This is the protocol for a feasibility randomised controlled trial with an embedded qualitative study and feasibility economic evaluation. If feasible, a later definitive trial will test the effectiveness and cost-effectiveness of an online intervention to enhance problem solving ability versus treatment as usual.

METHODS AND ANALYSIS

Twenty-five adolescents and their families identified by primary or secondary care clinicians at participating UK National Health Service Trusts will be recruited and individually randomised in a 1:1 ratio to receive the online intervention or treatment as usual. Participants will be followed up by online questionnaires 17 weeks after randomisation to capture acceptability of the study and intervention and resource use data. Qualitative interviews will capture participants' and clinicians' experiences of the study.

ETHICS AND DISSEMINATION

This study has been granted ethical approval by the South West-Exeter Research Ethics Committee (ref 17/SW/0083). Results will be disseminated via peer-reviewed publications and will inform the design of a larger trial.

“How Do We Solve This Task?”

Abstract. The study examines (a) whether gestational age relates to parental scaffolding (SCA), when controlling for child cognitive development, parenting stress, and socioeconomic status, and (b) how SCA links to parent–child problem-solving performance. The sample included 142 parents with a full-term or preterm 2-year-old toddler (corrected age). Parents’ SCA during one of two (randomly assigned) problem-solving tasks was rated on five scales (use of SCA means, cognitive support, metacognitive support, transfer or responsibility, contingency management). The results suggest that gestational age is positively related to parents’ transfer of responsibility and metacognitive support. The effects decrease, however, once covariates are controlled for. Regarding the problem-solving performance, direct effects were observed from parents’ cognitive and metacognitive support, transfer of responsibility, and contingency management. The data also confirm an indirect effect of parents’ use of SCA means on the problem-solving performance, partially mediated via parents’ cognitive support. Implications for the design of interventions are discussed.

Prenatal Risk Predicts Preschooler Executive Function: A Cascade Model

Little research has considered whether prenatal experience contributes to executive function (EF) development above and beyond postnatal experience. This study tests direct, mediated, and moderated associations between prenatal risk factors and preschool EF and IQ in a longitudinal sample of 1,292 children from the Family Life Project. A composite of prenatal risk factors (i.e., low birth weight, prematurity, maternal emotional problems, maternal prepregnancy obesity, and obstetric complications) significantly predicted EF and IQ at age 3, above quality of the postnatal environment. This relationship was indirect, mediated through infant general cognitive abilities. Quality of the postnatal home and child-care environments did not moderate the cascade model. These findings highlight the role of prenatal experience as a contributor to individual differences in cognitive development.
