Foundations of mathematics and literacy: The role of executive functioning components.

The current study investigated the relations between the three cognitive processes that comprise executive functioning (EF)-response inhibition, working memory, and cognitive flexibility-and individual components of mathematics and literacy skills in preschool children. Participants were 125 preschool children ranging in age from 3.12 to 5.26years (M=4.17years, SD=0.58). Approximately 53.2% were female, and the sample was predominantly Caucasian (69.8%). Results suggest that the components of EF may be differentially related to the specific components of early mathematics and literacy. For mathematics, response inhibition was broadly related to most components. Working memory was related to more advanced mathematics skills that involve comparison or combination of numbers and quantities. Cognitive flexibility was related to more conceptual or abstract mathematics skills. For early literacy, response inhibition and cognitive flexibility were related to print knowledge, and working memory was related only to phonological awareness. None of the EF components was related to vocabulary. These findings provide initial evidence for better understanding the ways in which EF components and academic skills are related and measured. Furthermore, the findings provide a foundation for further study of the components of each domain using a broader and more diverse array of measures.

Examining the Validity of Behavioral Self-Regulation Tools in Predicting Preschoolers' Academic Achievement.

Research Findings: The current study investigated the predictive utility of teacher-rated, observed, and directly assessed behavioral self-regulation skills to academic achievement in preschoolers. Specifically, this study compared how a teacher report (the Child Behavior Rating Scale), an observer report (the Observed Child Engagement Scale), and a direct assessment (the Head–Toes–Knees–Shoulders task) relate to early math and literacy skills. The sample consisted of 247 children from 31 preschool classrooms. Trained research assistants observed a subsample of 104 children. Results indicated significant positive relationships for teacher-rated and directly assessed behavioral self-regulation for early math and literacy skills. Teacher ratings were the strongest predictors of literacy, and the direct assessment emerged as the strongest predictor of math. Observed behavioral self-regulation was not significantly related to either academic domain. Practice or Policy: Discussion focuses on the domain specificity of behavioral self-regulation assessments and the importance of utilizing multiple measurement tools when assessing behavioral self-regulation and its relations to early achievement.

A Longitudinal Assessment of the Home Literacy Environment and Early Language.

This longitudinal assessment concentrated on the relation between the Home Literacy Environment (HLE) and early language acquisition during infancy and toddlerhood. In Study 1, after controlling for SES, a broadly-defined HLE predicted language comprehension in 50 infants. In Study 2, 27 children and their primary caregivers returned for further analyses. Findings revealed that the HLE measured in infancy predicted language production in toddlerhood, and maternal redirecting behaviors measured in toddlerhood were negatively associated with expressive language. Results across both studies indicate the importance of a broadly-defined HLE (including joint attention and parent-child conversation) for language development. Taken together, these findings highlight the importance of the HLE in supporting both receptive and expressive vocabulary growth in the second and third years of life.

Evaluating the Predictive Validity of the Computerized Comprehension Task: Comprehension Predicts Production

Until recently, the challenges inherent in measuring comprehension have impeded our ability to predict the course of language acquisition. The present research reports on a longitudinal assessment of the convergent and predictive validity of the MacArthur-Bates Communicative Development Inventories: Words and Gestures (CDI: WG; Fenson et al., 1994, 1993, 2007) and the Computerized Comprehension Task (CCT; Friend & Keplinger, 2003, 2008). The CDI: WG and the CCT evinced good convergent validity; however, the CCT better predicted subsequent parent reports of language production. Language sample data in the 3rd year confirm this finding: The CCT accounted for 24% of the variance in unique word use. These studies provide evidence for the utility of a behavior-based approach to predicting the course of language acquisition into production.

Examining the relations between executive function, math, and literacy during the transition to kindergarten: A multi-analytic approach.

The present study explored the bidirectional and longitudinal associations between executive function (EF) and early academic skills (math and literacy) across 4 waves of measurement during the transition from preschool to kindergarten using 2 complementary analytical approaches: cross-lagged panel modeling and latent growth curve modeling (LCGM). Participants included 424 children (49% female). On average, children were approximately 4.5 years old at the beginning of the study (M = 4.69, SD = .30) and 55% were enrolled in Head Start. Cross-lagged panel models indicated bidirectional relations between EF and math over preschool, which became directional in kindergarten with only EF predicting math. Moreover, there was a bidirectional relation between math and literacy that emerged in kindergarten. Similarly, LGCM revealed correlated growth between EF and math as well as math and literacy, but not EF and literacy. Exploring the patterns of relations across the waves of the panel model in conjunction with the patterns of relations between intercepts and slopes in the LGCMs led to a more nuanced understanding of the relations between EF and academic skills across preschool and kindergarten. Implications for future research on instruction and intervention development are discussed.

Residential Mobility, Inhibitory Control, and Academic Achievement in Preschool

Research Findings: The present study investigated the direct effects of residential mobility on childrens inhibitory control and academic achievement during the preschool year. It also explored fall inhibitory control and academic skills as mediators linking residential mobility and spring achievement. Participants included 359 preschool children (49% female) studied in the fall and spring of the preschool year (73% were enrolled in Head Start). Residential mobility was significantly and negatively associated with fall inhibitory control and fall math and literacy. Significant indirect effects of mobility were found for spring math and literacy through inhibitory control and fall achievement. Specifically, the negative relation between mobility and spring math and literacy was partially explained by lower scores on fall inhibitory control and academic skills. Practice or Policy: The current study contributes to the existing literature by specifying pathways linking frequent moves and achievement for young children. Policy implications are discussed.

A Pilot Evaluation of the "Positive Action" Prekindergarten Lessons.

There is a definite need for effective intervention programmes that address the social–emotional, character and healthy development of preschool children. Strong social-emotional skills are necessary for successful transitions to formal schooling and for healthy developmental trajectories. The Positive Action (PA) programme has a long history of effectiveness in schools (K-12) and communities, but has only recently developed lessons for preschool settings. The current study reports the results of the first evaluation of these lessons. Children were randomly assigned to classrooms/instructors who had previously decided to offer PA lessons or not. Instructors in both PA and control classrooms rated childrens behaviour at pretest and immediate post-test. Results suggest that the PA prekindergarten lessons are effective at improving childrens skills and behaviours across all of the domains that the programme addresses.

Professional Development Scholarships Increase Qualifications of Diverse Providers

Efforts to improve school readiness call for improvements in the professional qualifications of the early childhood workforce. It is critically important that these efforts are inclusive of a diverse workforce. Providers from diverse ethnic and linguistic backgrounds make up a sizable portion of the early childhood workforce, yet diversity continues to be disproportionally concentrated among providers with lower qualifications. This study examines the effect of a state-wide scholarship program on increasing qualifications for nondegree-seeking providers from diverse groups caring for children in early childhood settings. Data from two components of Oregon’s Quality Rating and Improvement System for early care and education were linked with individual provider identification numbers (N = 1,783): the Oregon Child Care Professional Development Registry (PD Registry) and the state-wide Betty Gray Scholarship Program. Findings revealed that providers from ethnic and linguistic minority backgrounds had lower qualifications, on average, but also accessed scholarships at elevated rates. Scholarships were associated with modest increases in professional qualifications for all groups of providers but did not reduce the gap in qualifications between providers from minority and nonminority backgrounds. Implications for teacher educators who deliver training and/or education to providers are discussed. Directions for future research and programming related to qualifications of early childhood providers are also presented.

Exploring cross-cultural variations in the development of executive function for preschoolers from low and high socioeconomic families:

This study investigated cross-cultural variation in the development of executive functioning (EF) across the preschool period for United States and Chinese children from low and high socioeconomic families using a longitudinal design. Participants included 216 preschool children (n = 125 from the US; n = 91 from Shanghai and Jiangxi, China). On average, children were approximately 4 years old. In the US sample, 56% were female, and in the Chinese sample, 54% were female. Results from multi-level models varied slightly with regard to specific EF domains, but generally indicated that Chinese children experienced greater gains in EF during the preschool period compared to US children. Cross-cultural differences in EF growth did not vary by socioeconomic status. These findings highlight cultural variability in the development of EF and provide a foundation for additional research exploring factors that may help explain differential growth in EF for Chinese children compared to US children during the preschool period.

Self-regulation as a correlate of weight status in preschool children

ABSTRACT The primary aim of this study was to examine associations between executive functioning (EF) and child weight status (categorized from body mass index [BMI] percentiles) in a sample of preschool children. Participants included 80 preschool children (mean age = 4.17 years, female = 52%). Hierarchical regression analyses as well as analysis of covariance were used to test hypotheses. Overall, results indicated that children with higher EF scores (on a composite score of three underlying EF components) had lower BMI percentiles and were more likely to be categorized as normal weight. Follow-up analyses revealed that only one individual EF component, cognitive flexibility, was significantly related to BMI percentile and weight status. Although the study sample was relatively small, findings suggest that this relation needs to be explored more in depth to understand how and why it is related and how that relation may be affected by intervention.
