Effects of foster care intervention and caregiving quality on the bidirectional development of executive functions and social skills following institutional rearing

Institutional rearing negatively impacts the development of children's social skills and executive functions (EF). However, little is known about whether childhood social skills mediate the effects of the foster care intervention (FCG) and foster caregiving quality following early institutional rearing on EF and social skills in adolescence. We examined (a) whether children's social skills at 8 years mediate the impact of the FCG on the development of EF at ages 12 and 16 years, and (b) whether social skills and EF at ages 8 and 12 mediate the relation between caregiving quality in foster care at 42 months and subsequent social skills and EF at age 16. Participants included abandoned children from Romanian institutions, who were randomly assigned to a FCG (n = 68) or care as usual (n = 68), and a never-institutionalized group (n = 135). At ages 8, 12, and 16, social skills were assessed via caregiver and teacher reports and EF were assessed via the Cambridge Neuropsychological Test Automated Battery. Caregiving quality of foster caregivers was observed at 42 months. FCG predicted better social skills at 8 years, which in turn predicted better EF in adolescence. Higher caregiver quality in foster care at 42 months predicted better social skills at 8 and 12 years, and better EF at 12 years, which in turn predicted 16-year EF and social skills. These findings suggest that interventions targeting caregiving quality within foster care home environments may have long-lasting positive effects on children's social skills and EF.     

Parents’ early book reading to children: Relation to children's later language and literacy outcomes controlling for other parent language input

It is widely believed that reading to preschool children promotes their language and literacy skills. Yet, whether early parent–child book reading is an index of generally rich linguistic input or a unique predictor of later outcomes remains unclear. To address this question, we asked whether naturally occurring parent–child book reading interactions between 1 and 2.5 years‐of‐age predict elementary school language and literacy outcomes, controlling for the quantity of other talk parents provide their children, family socioeconomic status, and children's own early language skill. We find that the quantity of parent–child book reading interactions predicts children's later receptive vocabulary, reading comprehension, and internal motivation to read (but not decoding, external motivation to read, or math skill), controlling for these other factors. Importantly, we also find that parent language that occurs during book reading interactions is more sophisticated than parent language outside book reading interactions in terms of vocabulary diversity and syntactic complexity.     

Cumulative risk disparities in children's neurocognitive functioning: a developmental cascade model

The current longitudinal study examined the role of cumulative social risk on children's theory of mind (ToM) and executive functioning (EF) across early development. Further, we also tested a cascade model of development in which children's social cognition at 18 months was hypothesized to predict ToM and EF at age 4.5 through intermediary language skills at age 3. We then examined whether this developmental mechanism varied as a function of social risk status. Participants were 501 children recruited when they were newborns, at which point eight psychosocial risk factors were assessed and combined into a metric of cumulative social disadvantage. Families were followed up at 18 months, at which point four social‐cognitive skills were assessed using developmentally sensitive tasks: joint attention, empathy, cooperation, and self‐recognition. Language was measured at age 3 using a standardized measure of receptive vocabulary. At age 3 and 4.5, EF and ToM were measured using previously validated tasks. Results showed that there were notable cumulative risk disparities in overall neurocognitive skill development, and these effects became more differentiated over time. Support was also found for a developmental mechanism wherein the effect of social cognition at 18 months on ToM and EF in the preschool period operated specifically through children's receptive language ability at age 3. This pathway functioned similarly for children with both low‐ and high‐risk backgrounds. These results extend previous findings by documenting the role of cumulative social disadvantage on children's neurocognition and the pathways that link key neurocognitive abilities across early development.     

Multilingual assessment of early child development: Analyses from repeated observations of children in Kenya

In many low‐ and middle‐income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a child's development, underscoring the importance of test translation and adaptation. To examine differences in vocabulary development by language of assessment, we adapted and validated instruments to measure developmental outcomes, including expressive and receptive vocabulary. We assessed 505 2‐to‐6‐year‐old children in rural communities in Western Kenya with comparable vocabulary tests in three languages: Luo (the local language or mother tongue), Swahili, and English (official languages) at two time points, 5–6 weeks apart, between September 2015 and October 2016. Younger children responded to the expressive vocabulary measure exclusively in Luo (44%–59% of 2‐to‐4‐year‐olds) much more frequently than did older children (20%–21% of 5‐to‐6‐year‐olds). Baseline receptive vocabulary scores in Luo (β = 0.26, SE = 0.05, p < 0.001) and Swahili (β = 0.10, SE = 0.05, p = 0.032) were strongly associated with receptive vocabulary in English at follow‐up, even after controlling for English vocabulary at baseline. Parental Luo literacy at baseline (β = 0.11, SE = 0.05, p = 0.045) was associated with child English vocabulary at follow‐up, while parental English literacy at baseline was not. Our findings suggest that multilingual testing is essential to understanding the developmental environment and cognitive growth of multilingual children.     

A parent intervention with a growth mindset approach improves children's early gesture and vocabulary development

Socioeconomic disparities in children's early vocabulary skills can be traced back to disparities in gesture use at age one and are due, in part, to the quantity and quality of communication children are exposed to by parents. Further, parents' mindsets about intelligence contribute to their interactions with their children. We implemented a parent gesture intervention with a growth mindset component with 47 parents of 10‐month‐olds to determine whether this approach would increase parents' use of the pointing gesture, infants' use of pointing, and child vocabulary growth. The intervention had an effect on parent gesture such that by child age 12‐months, parents who received the intervention increased in their pointing more than parents in the control condition. Importantly, the intervention also had a significant effect on child gesture use with parents. There was no main effect of the intervention on child vocabulary. Further, the effect of the intervention on pointing was stronger for parents who endorsed fixed mindsets at baseline, and had an added benefit of increased vocabulary growth from 10–18 months for children of those parents who endorsed fixed mindsets. Incorporating growth mindset approaches into parenting interventions is encouraged.     

Mentoring Relationship Quality and Maltreated Children's Coping

Coping strategies are believed to protect against the harmful effects of maltreatment on children's psychosocial outcomes. Caregivers are thought to be critical in helping children develop adaptive coping strategies, yet many maltreated children have poor and/or insecure relationships with their parents. A quality relationship with a caring, non‐parental adult (e.g., a mentor), however, may be one strategy to promote healthy coping among maltreated children. Children (N = 154) in this study participated in a mentoring and skill‐based program for maltreated preadolescents placed in foster care. Hierarchical regression was used to assess the association between children's reports of their relationship with their mentor at the end of the intervention and four coping strategies (i.e., Active, Support‐seeking, Avoidance, and Distraction) 6 months following the intervention, while accounting for baseline coping strategies and other demographic factors. Above and beyond the covariates, better mentoring relationship quality was associated with children's greater use of Active and Distraction coping 6‐month post‐intervention. Mentoring relationship quality was not significantly associated with children's Avoidance or Support‐seeking coping. The findings suggest that mentoring programs may be a fruitful approach to improving vulnerable children's coping skills. Healthy coping is hypothesized to protect against the harmful effects of maltreatment and to promote resilience in the face of multiple stressors (Banyard & Williams, 2007 ; Boxer & Sloan‐Power, 2013; Cicchetti & Rogosch, 2009). It remains unclear, however, how best to promote positive coping among maltreated children, who are disproportionately exposed to numerous adverse childhood experiences (Raviv, Taussig, Culhane & Garrido, 2010). Theories of coping emphasize the importance of coping socialization through quality parent–child relationships (Kliewer et al., 2006; Skinner & Wellborn, 1994 ). Unfortunately, many maltreated children are exposed to poor quality and/or inadequate caregiving (Baer & Martinez, 2006), which may place them at risk for engaging in unhealthy or inappropriate forms of coping. It is reasonable to expect that positive relationships with other non‐parental adults (e.g., mentors) would affect coping behaviors given the positive impact that quality relationships have on a myriad of emotional and behavioral child outcomes (DuBois, Portillo, Rhodes, Silverthorn & Valentine, 2011; Keller & Pryce, 2012; Thomson & Zand, 2010 ). Because children in foster care often transition in and out of schools and home environments, a quality relationship with a mentor (a consistent presence in the child's life) may be well suited to promote healthy coping strategies.     

Improving mother–child interaction in low‐income Turkish–Dutch families: A study of mechanisms mediating improvements resulting from participating in a home‐based preschool intervention program

This study examined whether the effects on cognitive and language outcomes of a recently developed home‐based educational intervention program, Opstap Opnieuw, for 4–6‐years‐old disadvantaged children could be explained by improved mother–child interaction. The present sample (n=30) was drawn from a larger sample of Turkish–Dutch families (n=181) for which in a previous study significant effects of Opstap Opnieuw were found on children's (first) language and cognitive pre‐math skill, 5 months after the program ended. The present study focused on two facets of interaction quality as possible mediators of these program effects: the mean cognitive distancing level of mothers' communication and instruction behaviour as an indicator of the cognitive and verbal stimulation provided, and the degree of cooperation as an indicator of mothers' social‐emotional support to their children. Both measures were based on systematic observation of mother–child interaction during sorting tasks. Participation in the program appeared to improve mothers' social‐emotional support behaviour substantially, but not their cognitive distancing behaviour. For Turkish (first language) vocabulary, about half of the program effect appeared to be mediated by the improved social‐emotional support. For cognitive pre‐mathematical skills, two‐thirds of the program effect appeared to be mediated by improved social‐emotional support. Mothers' cognitive distancing was moderately‐strongly related to children's vocabulary development, but did not mediate program effects. Some implications of the results are discussed.

THE MAGIC OF PLAY: LOW‐INCOME MOTHERS’ AND FATHERS’ PLAYFULNESS AND CHILDREN'S EMOTION REGULATION AND VOCABULARY SKILLS

Using data from a diverse sample of low‐income families who participated in the Early Head Start Research Evaluation Project (n = 73), we explored the association between mothers’ and fathers’ playfulness with toddlers, toddler's affect during play, and children's language and emotion regulation at prekindergarten. There were two main findings. First, fathers’ playfulness in toddlerhood was associated with children's vocabulary skills in prekindergarten whereas mothers’ playfulness was related to children's emotion regulation. Cross‐parental effects were found only for mothers. The association between mothers’ playfulness and children's vocabulary and emotion regulation was strengthened when fathers engaged in more pretend play and when children were affectively positive during the play. These findings show that playfulness is an important source of variation in the vocabulary and emotion regulation of children growing up in low‐income families. They also point to domain‐specific ways that mothers and fathers promote children's regulatory and vocabulary skills, and highlight the importance of children's positive engagement in play.     

Bilingualism alters children's frontal lobe functioning for attentional control

Bilingualism is a typical linguistic experience, yet relatively little is known about its impact on children's cognitive and brain development. Theories of bilingualism suggest that early dual‐language acquisition can improve children's cognitive abilities, specifically those relying on frontal lobe functioning. While behavioral findings present much conflicting evidence, little is known about its effects on children's frontal lobe development. Using functional near‐infrared spectroscopy (fNIRS), the findings suggest that Spanish–English bilingual children (n = 13, ages 7–13) had greater activation in left prefrontal cortex during a non‐verbal attentional control task relative to age‐matched English monolinguals. In contrast, monolinguals (n = 14) showed greater right prefrontal activation than bilinguals. The present findings suggest that early bilingualism yields significant changes to the functional organization of children's prefrontal cortex for attentional control and carry implications for understanding how early life experiences impact cognition and brain development.     

Supporting early oral language skills for English language learners in inner city preschool provision

Background. A significant number of children now enter formal education in England with reduced levels of proficiency in oral language. Children who come from disadvantaged backgrounds and who are English language learners (ELL) are at risk of limited oral language skills in English which impacts on later educational achievement. Aims. This paper reports the development of a theoretically motivated oral language intervention, Talking Time, designed to meet the needs of preschool children with poor language skills in typical preschool provision. Sample. One hundred and forty‐two 4‐year‐old children attending three inner city preschools in a disadvantaged area of London, England. Method. This is a quasi‐experimental intervention study comparing children exposed to Talking Time with children exposed to a contrast intervention and children receiving the statutory early years curriculum. Measures were taken of both targeted and non‐targeted language and cognitive skills. Results. Data were analysed for the ELL. The intervention had a significant effect on vocabulary, oral comprehension, and sentence repetition but not narrative skills. As predicted, there were no effects on the skills which were not targeted. Conclusions. Regular evidence‐based oral language interactions can make significant improvements in children's oral language. There is a need to examine the efficacy of more intensive interventions to raise language skills to allow learners to access the curriculum.     

Effects of early institutionalization on the development of emotion processing: a case for relative sparing?

We tested the capacity to perceive visual expressions of emotion, and to use those expressions as guides to social decisions, in three groups of 8‐ to 10‐year‐old Romanian children: children abandoned to institutions then randomly assigned to remain in ‘care as usual’ (institutional care); children abandoned to institutions then randomly assigned to a foster care intervention; and community children who had never been institutionalized. Experiment 1 examined children's recognition of happy, sad, fearful, and angry facial expressions that varied in intensity. Children assigned to institutional care had higher thresholds for identifying happy expressions than foster care or community children, but did not differ in their thresholds for identifying the other facial expressions. Moreover, the error rates of the three groups of children were the same for all of the facial expressions. Experiment 2 examined children's ability to use facial expressions of emotion to guide social decisions about whom to befriend and whom to help. Children assigned to institutional care were less accurate than foster care or community children at deciding whom to befriend; however, the groups did not differ in their ability to decide whom to help. Overall, although there were group differences in some abilities, all three groups of children performed well across tasks. The results are discussed in the context of theoretical accounts of the development of emotion processing.     

Joint Book Reading and Receptive Vocabulary: A Parallel Process Model

The purpose of the present study was to understand the reciprocal, bidirectional longitudinal relation between joint book reading and English receptive vocabulary. To address the research goals, a nationally representative sample of Head Start children, the Head Start Family and Child Experiences Survey (2003 cohort), was used for analysis. The children were aged 3–4 years at programme entry. The mothers' average age at programme entry was 39 years old. A parallel process model was utilized to examine the growth factors of joint book reading and receptive vocabulary in parallel. Three significant findings emerged: (1) initial levels of English receptive vocabulary and joint book reading positively covaried; (2) English receptive vocabulary and joint book reading were positively and reciprocally related to each other; and (3) slopes for joint book reading and English receptive vocabulary negatively covaried. Results suggest that joint book reading can support and scaffold Head Start children's English receptive vocabulary. Reciprocally, Head Start children's English receptive vocabulary appears to predict the extent to which they engage in joint book reading at home. Moreover, the frequency of joint book reading decreases as the children demonstrate higher levels of English receptive vocabulary. Copyright © 2015 John Wiley & Sons, Ltd.     

Once a French Speaker,Always a French Speaker? Bilingual Children's Thinking About the Stability of Language

Despite early emerging and impressive linguistic abilities, young children demonstrate ostensibly puzzling beliefs about the nature of language. In some circumstances monolingual children even express the belief that an individual's language is more stable than her race. The present research investigated bilingual children's thinking about the relative stability of language and race (Kinzler & Dautel, 2012). Five‐to six‐year‐old bilingual children were asked to judge whether a target child who varied in race (White or Black) and language (English or French) would grow up to be an adult who maintained the target child's race or her language. Similar to many monolingual children, a heterogeneous group of bilingual children on average chose the language‐match. Yet French‐English bilingual children were relatively more likely to choose the race‐match, especially when tested in their non‐dominant language. Specific experience with relevant languages, and communicating in a non‐dominant language, may contribute to children's developing metalinguistic success and their thinking about social categorization.     

The effects of early foster care intervention on attention biases in previously institutionalized children in Romania

Children raised in institutions experience psychosocial deprivation that can negatively impact attention skills and emotion regulation, which subsequently may influence behavioral regulation and social relationships. The current study examined visual attention biases in 8‐year‐old children who were part of the Bucharest Early Intervention Project (BEIP). Relations among attention biases and concurrent social outcomes were also investigated. In early childhood, 136 children abandoned at birth or shortly thereafter into institutional care were randomized to receive a high‐quality foster care intervention or care‐as‐usual within the context of the Bucharest Early Intervention Project (BEIP). At 8 years of age, 50 care‐as‐usual, 55 foster care, and 52 community controls performed a behavioral dot‐probe task, and indices of attention biases to threat and positive stimuli were calculated. Concurrent data on social behavior were collected. Children placed into the foster care intervention had a significant attention bias toward positive stimuli, while children who received care‐as‐usual had a significant bias toward threat. Children in the foster care intervention had a significantly larger positive bias when compared to the care‐as‐usual group. A positive bias was related to more social engagement, more prosocial behavior, less externalizing disorders, and less emotionally withdrawn behavior. The magnitude of positive bias was predicted by age of placement into foster care among children with a history of institutionalization. An attention bias towards positive stimuli was associated with reduced risk for behavioral problems amongst children who experienced early psychosocial deprivation. Research assessing attention biases in children experiencing early environmental stress may refine our understanding of the mechanisms underlying risk for later psychiatric and social disorders and inform prevention efforts.     

From terrible twos to sassy sixes: The development of vocabulary and executive functioning across early childhood

Across the early childhood period of development, young children exhibit considerable growth in their executive functioning (EF) and vocabulary abilities. Understanding the developmental trajectory of these seemingly interrelated processes is important as both early vocabulary and EF have been shown to predict critical academic and socio-emotional outcomes later in childhood. Although previous research suggests that EF and vocabulary are correlated in early childhood, much of the existing longitudinal research has focused on unidirectional relations among preschool child samples. The current large-scale study, therefore, sought to examine whether children's vocabulary and EF abilities are bidirectionally related over time across four measurement waves in early childhood (i.e., at ages 2, 3, 4, and 6). At each timepoint, children's vocabulary skills were positively correlated with their concurrent EF abilities. After controlling for child sex and maternal education status, the best-fitting, cross-lagged panel model was a unidirectional model whereby children's early vocabulary scores predicted their later EF performance at each timepoint. Although age 2 EF significantly predicted age 3 vocabulary size, this association was no longer significant after accounting for maternal education status. Our results illustrate that vocabulary size plays an important role in predicting children's later EF performance across various timepoints in early childhood, even after controlling for children's initial EF scores. These findings have important implications for intervention research as fostering early vocabulary acquisition may serve as a possible avenue for improving EF outcomes in young children.

Research Highlights

• Children's vocabulary size is positively correlated with their concurrent executive functioning skill at ages 2, 3, 4, and 6
• Young children's early vocabulary scores predict their later EF performance across measurement waves, even after controlling for initial EF skill
• There is stability in children's relative vocabulary size and executive functioning performance over time in early childhood

     

Postnatal trajectories of maternal depressive symptoms: Postpartum antecedents and differences in toddler adjustment

Infants are uniquely vulnerable to maternal depression's noxious effects, but few longitudinal studies have tried to identify discrete postnatal trajectories of maternal depressive symptoms (MDS) beginning in infancy. This study extends evidence of heterogeneous change in postnatal MDS by examining their cross-contextual antecedents in infancy and their consequences for children's early behavior problems and language skills in late toddlerhood. A community sample of mother–child dyads (N = 235, 72% Caucasian) was assessed when children were 7, 15, and 33 months old. Mothers reported their socioeconomic status (SES), social support, marital relationship quality, family dysfunction, parenting stress, and infants’ functional regulatory problems at 7 months postpartum, and children's internalizing and externalizing symptoms at 33 months. Children completed a receptive vocabulary assessment at 33 months in the lab. Latent class growth analysis identified three postnatal MDS trajectory classes that fit the data best: low-decreasing, moderate, and increasing. Psychosocial measures at seven months postpartum primarily predicted membership to these postnatal trajectory classes, which subsequently differed in children's internalizing, externalizing, and receptive vocabulary in late toddlerhood, controlling for family SES and functional regulatory problems in infancy. We discuss salient antecedents and consequences of postnatal depression for mothers and their offspring.     

The Development of Internal State Language during the Third Year of Life: A Longitudinal Parent Report Study

Children's talk about the mind has been scarcely studied in non‐English speakers. For this reason, this longitudinal study documents age‐related changes in German‐speaking children's internal state language. At 24, 30 and 36 months, children were administered general language tests and their internal state vocabulary levels were obtained via parental report. The developmental transition from a vocabulary rich in physiological, perceptual and desire terms to a vocabulary rich in a wider range of mental concepts confirmed previous research with French‐speaking and English‐speaking children and research in children's internal state comprehension. Further, children's category scores proved to be developmentally stable. Finally, with increasing age, children's category scores became more specifically related to each other, independent of general language skills. The results are discussed in regard to the universality of children's talk about the mind. Copyright © 2012 John Wiley & Sons, Ltd.     

ANS acuity and mathematics ability in preschoolers from low‐income homes: contributions of inhibitory control

Recent findings by Libertus, Feigenson, and Halberda (2011) suggest that there is an association between the acuity of young children's approximate number system (ANS) and their mathematics ability before exposure to instruction in formal schooling. The present study examined the generalizability and validity of these findings in a sample of preschoolers from low‐income homes. Children attending Head Start (N = 103) completed measures to assess ANS acuity, mathematics ability, receptive vocabulary, and inhibitory control. Results showed only a weak association between ANS acuity and mathematics ability that was reduced to non‐significance when controlling for a direct measure of receptive vocabulary. Results also revealed that inhibitory control plays an important role in the relation between ANS acuity and mathematics ability. Specifically, ANS acuity accounted for significant variance in mathematics ability over and above receptive vocabulary, but only for ANS acuity trials in which surface area conflicted with numerosity. Moreover, this association became non‐significant when controlling for inhibitory control. These results suggest that early mathematical experiences prior to formal schooling may influence the strength of the association between ANS acuity and mathematics ability and that inhibitory control may drive that association in young children.     

Early lexical development of children raised in institutional care in Russia

Children abandoned to institutions display a host of developmental delays, including those involving general cognition and language. The majority of published studies focus on children over 3 years of age; little is known about whether these delays may be detected earlier when children undergo rapid lexical development. To investigate the early language development of children raised in institutional settings in the Russian Federation, we compared a group of children in institutional care (n = 36; 8–35 months) to their age-matched peers raised in biological families, who have never been institutionalized (n = 72) using the Russian version of the CDI. The results suggest that institutionalization is associated with pronounced delays in children's early language development with large and robust effect sizes. Among children with a history of institutionalization, these delays are also associated with difficulties in Daily Living skills, communication, and socialization.
