Quality of Center Child Care and Infant Cognitive and Language Development

The relations between quality of center-based child care and infant cognitive and language development were examined in a sample of 79 African-American 12-month-old infants. Both structural and process measures of quality of child care were collected through interviews with the center director and observation of the infant classroom. Results indicated that quality of infant care positively correlated with scores on standardized assessments of cognitive development ( Bayley Scales of Infant Development ), language development (Sequenced Inventory of Communication Development), and communication skills (Communication and Symbolic Behavior Scales). In addition, quality of care in child care centers and at home was positively related. Analyses that adjusted for this association between quality of care at home and in child care suggested that the process measure of quality of child care independently related to the infant's cognitive development, and one structural measure, the infant-adult ratio, independently related to the infant's overall communication skills. Neither child nor family factors was found to moderate the association between child care quality and infant development. These findings, in conjunction with the growing child care literature, suggest that researchers and policymakers should focus on how quality of child care can be improved to enhance, not impair, infant development.     

The relation of child care to cognitive and language development. National Institute of Child Health and Human Development Early Child Care Research Network

Children from 10 sites in the United States were followed from birth to age 3 to determine how experiences in child care relate to cognitive and language development (Ns varied between 595 and 856, depending on the assessment). Multiple assessments of family and child care environments and of cognitive and language competence were collected. Analyses that adjusted for maternal vocabulary score, family income, child gender, observed quality of the home environment, and observed maternal cognitive stimulation indicated that the overall quality of child care, and language stimulation in particular, was consistently but modestly related to cognitive and language outcomes at ages 15, 24, and 36 months. The effect sizes for high (top quartile) versus low (bottom quartile) quality ranged from .18 to .48. After adjusting for child care quality, cumulative experience in center-based care was associated with better outcomes than was participation in other types of care. The amount of time children spent in care was not related to outcomes. Children in exclusive maternal care did not differ systematically from children in child care. Tests for lagged relations of earlier child care experiences to later performance (adjusting for current child care) showed that language stimulation predicted subsequent cognitive and language performance 9 to 12 months later. Although children in center care at age 3 performed better than children in other types of care, earlier experience in child care homes was associated with better performance at age 3 than was experience in other types of care. The relations of child care variables to outcomes did not vary consistently as a function of family income, quality of home environment, child gender, or ethnic group.     

Caregiver–child verbal interactions in child care: A buffer against poor language outcomes when maternal language input is less

Recent research has suggested that high quality child care can buffer young children against poorer cognitive and language outcomes when they are at risk for poorer language and readiness skills. Most of this research measured the quality of parenting and the quality of the child care with global observational measures or rating scales that did not specify the exact maternal or caregiver behaviors that might be causally implicated in the buffering of these children from poor outcomes. The current study examined the actual language by the mother to her child in the home and the verbal interactions between the caregiver and child in the child care setting that might be implicated in the buffering effect of high quality childcare. The sample included 433 rural children from the Family Life Project who were in child care at 36 months of age. Even after controlling for a variety of covariates, including maternal education, income, race, child previous skill, child care type, the overall quality of the home and quality of the child care environment; observed positive caregiver–child verbal interactions in the child care setting interacted with the maternal language complexity and diversity in predicting children's language development. Caregiver–child positive verbal interactions appeared to buffer children from poor language outcomes concurrently and two years later if children came from homes where observed maternal language complexity and diversity during a picture book task was less.     

Parental contribution to child’s early language and interest in books

The relationships between parents’ age, education, literacy activities and shared reading with the child and children’s language skills and early interest in books were examined in a longitudinal study of 108 children. Parents reported on their children’s lexical and grammatical development by using the MacArthur Communicative Development Inventories (the CDIs) at the ages of 14 and 24 months. The Bayley Scales of Infant Development were administered to the children in a laboratory setting at 24 months. Information on parental background variables was obtained through a questionnaire before the children’s birth. Book reading habits were inquired when the children were 2 years of age. Mothers’ education, literacy activities and shared reading with the child were shown to be more strongly associated with the 2-year-olds’ lexical and grammatical skills than were those of father. A corresponding association to parental background variables emerged regardless of whether parental report data or scores on the structured test were employed as the child language measure. Shared reading with the father was found to be linked to children’s early interest in books. The children who exhibited greater interest in books were likely to be read to by mothers and fathers more frequently than other children. These children also had larger vocabularies than did children with low interest in books. The role of endogenous and exogenous variables in explaining children’s language skills and early book reading interest are discussed.     

Mixed-Age Interactions in Family Child Care

Preschool-age children's experiences within the mixed-age setting of family child care homes and the influences of these experiences on development were examined. Development variables included social and cognitive play, and receptive and expressive language. Consistent with Vygotsky's developmental theory, children's interactions with mixed-age peers were more powerful predictors of development than the mere availability of mixed-age peers. Interactions with older peers were associated with more complex cognitive play behaviors. Interactions with younger and same-age peers were associated with less complex social and cognitive play and lower receptive language scores. Characteristics of the child care setting appeared to moderate children's behavior in the mixed-age environment. Children in higher quality family child care homes with responsive caregivers were less likely to interact with younger children. No evidence was found of different developmental outcomes across developmental domains for older versus younger children.

Threshold analysis of association between child care quality and child outcomes for low-income children in pre-kindergarten programs

Over the past five decades, the federal government and most states have invested heavily in providing publicly-funded child care and early education opportunities for 3- and 4-year-old children from low-income families. Policy makers and parents want to identify the level or threshold in quality of teacher–child interaction and intentional instruction related to better child outcomes to most efficiently use child care to improve school readiness. Academic and social outcomes for children from low-income families were predicted from measures of teacher–child interactions and instructional quality in a spline regression analysis of data from an 11-state pre-kindergarten evaluation. Findings suggested that the quality of teacher–child interactions was a stronger predictor of higher social competence and lower levels of behavior problems in higher than in lower quality classrooms. Further, findings suggested that quality of instruction was related to language, read and math skills more strongly in higher quality than in lower quality classrooms. These findings suggest that high-quality classrooms may be necessary to improve social and academic outcomes in pre-kindergarten programs for low-income children.     

Literacy skills in children with cochlear implants: the importance of early oral language and joint storybook reading

The goal of this study was to longitudinally examine relationships between early factors (child and mother) that may influence children's phonological awareness and reading skills 3 years later in a group of young children with cochlear implants (N = 16). Mothers and children were videotaped during two storybook interactions, and children's oral language skills were assessed using the "Reynell Developmental Language Scales, third edition." Three years later, phonological awareness, reading skills, and language skills were assessed using the "Phonological Awareness Test," the "Woodcock-Johnson-III Diagnostic Reading Battery," and the "Oral Written Language Scales." Variables included in the data analyses were child (age, age at implant, and language skills) and mother factors (facilitative language techniques) and children's phonological awareness and reading standard scores. Results indicate that children's early expressive oral language skills and mothers' use of a higher level facilitative language technique (open-ended question) during storybook reading, although related, each contributed uniquely to children's literacy skills. Individual analyses revealed that the children with expressive standard scores below 70 at Time 1 also performed below average (<85) on phonological awareness and total reading tasks 3 years later. Guidelines for professionals are provided to support literacy skills in young children with cochlear implants.     

Diversity, child care quality, and developmental outcomes

It is widely accepted that high quality child care enhances children’s cognitive and social development, but some question whether what constitutes quality care depends on the child’s ethnic and cultural background. To address this question, secondary analysis of data from the two largest studies of child care experiences in the United States, Cost, Quality, and Outcomes Study and the NICHD Study of Early Child Care, tested whether standard measures of child care quality were less reliable or valid for African-American and English-speaking Latino children than for white children. Widely used measures of child care quality showed comparably high levels of reliability and similar levels of validity for white, African-American, and Latino children. Analyses tested whether cognitive and social skills were related to child care quality, the match between child’s and caregiver’s ethnicity, and the match between the mother’s and caregiver’s beliefs about child-rearing. Results indicated children from all three ethnic groups showed higher levels of cognitive and social skills on standardized assessments shown to predict school success when caregivers were sensitive and stimulating. Children’s skills were not consistently related to whether the child’s and caregiver’s ethnicity matched or whether the mother’s and caregiver’s beliefs about child-rearing were similar. These two large studies suggest that children from all three ethnic groups benefit from sensitive and stimulating care on child outcomes related to school success. The results are interpreted as indicating that the global dimension of quality may be reflected in very different types of practices that reflect cultural differences.     

The early developmental competencies and school readiness of low-income,immigrant children: Influences of generation,race/ethnicity,and national origins

Though much valuable research has been conducted on the academic achievement of school-age immigrant youth, less is known about the early developmental competencies of immigrant children during the preschool years. This study describes the school readiness of 2194 low-income children receiving subsidies to attend child care with emphasis on how nativity status (generation), race/ethnicity, and national origins might be related to children's preparedness for kindergarten. The Learning Accomplishment Profile–Diagnostic (LAP-D) was used to measure cognitive and language skills, while teacher-report on the Devereux Early Childhood Assessment (DECA) measured socio-emotional protective factors and behavior concerns. Results demonstrate that variation does exist in school readiness according to nativity-based factors. First- and second-generation immigrants lagged behind children in non-immigrant families in cognitive and language skills but excelled by comparison in socio-emotional skills and behavior. In many cases, first-generation immigrant children showed more advanced development than second-generation immigrant children, providing some evidence in the early years for an immigrant advantage. The present study raises awareness regarding some of the strengths immigrant children demonstrate from a very young age—strengths that can be built upon to encourage their later success and academic achievement.     

Determinants of child outcomes in a cohort of children in the Free Pre-School Year in Ireland, 2012/2013

The study analyses determinants of child outcomes in a cohort of children who participated in the Free Pre-School Year. Child outcomes are measured through a before-and-after assessment of children using the Early Development Instrument. The sample comprises 448 children in 70 early years centres. There are three main findings. First, children with more or better skills at the beginning of the study period tended to have more or better skills at the end of this period, and vice versa, indicating that the broad parameters of a child's progress during the Free Pre-School Year have already been set by the child's development during previous years. Second, child and family characteristics are the largest set of measured influences on child outcomes by comparison with the pre-school system, with social class being the single biggest influence. Third, there were significant skill gaps between children at the start of the Free Pre-School Year which remained unchanged or widened during the year. The main conclusion is that the measures required to improve child outcomes in pre-school need to extend well beyond the confines of the early years sector to include all influences, especially family and social class influences, on child development and need to begin at the start of the child's life.     

Social Risk and Protective Child,Parenting, and Child Care Factors in Early Elementary School Years

Objective. African American children exposed to multiple social risk factors during early childhood often experience academic difficulties, so identification of protective factors is important. Design. Academic and school behavior trajectories from kindergarten through third grade were studied among 75 African American children who have been followed prospectively since infancy to test hypothesized protective factors: quality of home and child care environments during early childhood, child language and social skills at entry to kindergarten, and school characteristics. Results. Children exposed to multiple risks in early childhood showed lower levels of academic and social-emotional skills from kindergarten through third grade. Parenting mediated the association with risk. Children's language skills, parenting, and child care quality serve as protective factors in acquisition of mathematics skills and reduction in problem behaviors during the first 4 years of primary school for African American children facing multiple risks. Attending a school with a higher proportion of children from low-income families might predict increasing numbers of problem behaviors over time. Conclusions. Exposure to social risk in early childhood negatively predicted academic achievement and adjustment during early elementary school for African American children, in part through associations between exposure to social risk and less responsive and stimulating parenting. Furthermore, the negative associations between risk and academic outcomes were substantially weaker when children had more responsive and sensitive parents or child care providers or entered school with stronger language skills.     

The quality of toddler child care and cognitive skills at 24 months: Propensity score analysis results from the ECLS-B

Over half of the toddlers in the US experience routine nonparental care, but much less is known about early care than about preschool care. This study analyzed 2-year-old child care and child outcome data from the nationally representative ECLS-B sample of children born in 2001. At two-years of age, 51% of children experienced exclusive parental care, 18% relative care, 15% family child care, and 16% center care. More children in nonparental care were in medium quality care (61%) than in high quality (26%) or low quality (13%) care. Low-income children were more likely than non-low income children to be cared for by their parents and, when in care, were more often in lower quality care. The impact of toddler care quality on cognitive skills was estimated using propensity score adjustments to account for potential selection confounds due to family and child characteristics. Children's cognitive scores were higher in high or medium quality care than in low quality care, but no evidence emerged suggesting that poverty moderated the quality effects. Nevertheless, this suggests that increasing the proportion of low-income children in high quality care could reduce the achievement gap because low-income children are very unlikely to experience high quality care.     

Effects of home environment and center-based child care quality on children's language,communication, and literacy outcomes

This study examined the joint effects of home environment and center-based child care quality on children's language, communication, and early literacy development, while also considering prior developmental level. Participants were 95 children (46 boys), assessed as toddlers (mean age = 26.33 months; Time 1) and preschoolers (mean age = 68.71 months; Time 2) and their families. At both times, children attended center-based child care classrooms in the metropolitan area of Porto, Portugal. Results from hierarchical linear models indicated that home environment and preschool quality, but not center-based toddler child care quality, were associated with children's language and literacy outcomes at Time 2. Moreover, the quality of preschool classrooms moderated the association between home environment quality and children's language and early literacy skills – but not communication skills – at Time 2, suggesting the positive cumulative effects of home environment and preschool quality. Findings further support the existence of a detrimental effect of low preschool quality on children's language and early literacy outcomes: positive associations among home environment quality and children's developmental outcomes were found to reduce substantially when children attended low-quality preschool classrooms.     

The play and language behavior of mothers with and without dyslexia and its association to their toddlers' language development

The play and language behavior of mothers with (n = 49) and without (n = 49) specific reading disabilities (RD) was investigated during play with their 14-month-old children. The contribution of maternal behavior to the language development of their children was examined. The children's receptive and expressive language skills were assessed longitudinally at 14, 18, and 30 months, using the MacArthur Communicative Development Inventories and the Reynell Developmental Language Scales. Children with and without familial risk for RD did not differ from each other in any play or language measures at these ages. No group differences were found for mothers' manifestations of nonsymbolic play and language. However, the typically reading (TR) mothers produced significantly more symbolic play and language in play interactions with their child than did the mothers with RD. The correspondence between mother-child symbolic play and maternal play-related language was also higher for the TR group than it was for the RD group. The mothers' symbolic play did not show any relation to their children's language development, but their expressions of symbolic language did show a relationship. The mothers' child-directed symbolic language contributed significantly toward the comprehension skills of 14- and 18-month-olds in the RD group. This association, however, was lower at 30 months, at which point it was reliably present for the first time in the TR group.     

Motor Skills and Executive Function Contribute to Early Achievement in East Asia and the Pacific

Research Findings: This study examined the contributions of motor skills and executive function (EF) to early achievement. Participants were 7,797 children (3,889 girls) between 36 and 72 months of age from 6 countries in East Asia and the Pacific. Fine and gross motor skills, EF, language and literacy achievement, and mathematics achievement were evaluated using the East Asia-Pacific Early Child Development Scales, a tool that assesses child development in 7 domains. Children’s caregivers provided demographic information. There were 3 salient findings. First, gross and fine motor skills predicted both language and literacy and mathematics achievement. Second, in general, fine motor skills contributed more to the prediction of early achievement than gross motor skills. However, there were no differences between the contributions of fine and gross motor skills to the prediction of early language and literacy in Papua New Guinea or early mathematics in Timor-Leste. Third, EF partially mediated the relation between both early achievement and gross and fine motor skills in the overall sample, Cambodia, and Timor-Leste and fully mediated the association of gross motor skills and early achievement in China, Mongolia, Papua New Guinea, and Vanuatu. Practice or Policy: Implications of the findings for early childhood education are discussed.     

Does Higher Quality Early Child Care Promote Low‐Income Children’s Math and Reading Achievement in Middle Childhood?

Higher quality child care during infancy and early childhood (6–54 months of age) was examined as a moderator of associations between family economic status and children's ( N  = 1,364) math and reading achievement in middle childhood (4.5–11 years of age). Low income was less strongly predictive of underachievement for children who had been in higher quality care than for those who had not. Consistent with a cognitive advantage hypothesis, higher quality care appeared to promote achievement indirectly via early school readiness skills. Family characteristics associated with selection into child care also appeared to promote the achievement of low-income children, but the moderating effect of higher quality care per se remained evident when controlling for selection using covariates and propensity scores.     

Socioeconomic status,parent report of children’s early language skills,and late literacy skills: a long term follow-up study among Chinese children

Previous research on the longitudinal prediction of literacy development has focused mainly on the relationship between early cognitive/language skills and late literacy skills. The present study aimed to test the reliability of a number of measures reported by parents as compared to measuring cognitive and language skills in predicting subsequent reading achievement. Two hundred sixty-two Chinese children were administered four cognitive and language skills over three years at the preliterate stage. Additional information on children’s family socioeconomic status (SES), children’s early language skills, familial reading performance and habits, and familial handedness based on the observations of parents was collected. Performance on these variables in relation to subsequent literacy skills at 11 years of age was examined. SES and children’s early language skills significantly predicted subsequent literacy skills. Even with a number of cognitive and language skills statistically controlled, parental reports of children’s early language skills still contributed to reading comprehension. Poor readers defined at 11 years of age had lagged behind in early language skills, as well as family reading performance and habits, as compared to typically developing readers. These findings suggest that SES and parental estimates of children’s early language skills are useful for predicting children’s subsequent reading achievement.
