The aim of the present study was to test environmental and cognitive variables as possible cross-domain predictors of early literacy and numeracy skills. One hundred forty-eight preschool children (mean age = 64.36 months ± 3.33) were enrolled in the study. The battery included a home literacy and home numeracy questionnaire, measures and…

Background: The facilitating role of sleep for language learning is well-attested in adults and to a lesser extent in infants and toddlers. However, the longitudinal relationship between sleep patterns and early vocabulary development is not well understood. Methods: This study investigates how measures of sleep are related to the development of…

This study investigates whether young heritage speakers, either simultaneous or sequential bilinguals, have limited vocabulary knowledge in their family language compared to matched monolingual counterparts and, if so, what factors help to account for this difference. These factors include age, age at emigration, length of emigration, frequency of…

This study investigated the role of parental support and selected family variables in the first (L1) and second language (L2) vocabulary development of Japanese heritage language (JHL) high school students in the United States. Eighty-two JHL students ages 15-18 from eight hoshuukoo (i.e., supplementary academic schools for Japanese-speaking…

This study explored effects of Spanish oral language skills (vocabulary and syntax) on the development of English oral language skills (vocabulary, morphology, semantics, syntax) and reading comprehension among 156 bilingual Latino children in second through fifth grade whose first language was Spanish and whose second language was English. Using…

Models of irregular word reading that take into account both child- and word-level predictors have not been evaluated in typically developing children and children with reading difficulty (RD). The purpose of the present study was to model individual differences in irregular word reading ability among 5th grade children (N = 170), oversampled for…

This study investigated the potential interrelationship between parental (maternal) and expert assessments of the expressive and receptive language skills of 12- to 18-month-old children. The language activities of 27 children were monitored by their mothers (MCDI scale: Lyytinen, 2000. "Varhaisen kommunikaation ja kielen kehityksen…

The Modified Checklist for Autism in Toddlers (M-CHAT) is a 23-item questionnaire used in primary screening of Autism Spectrum Disorder (ASD). The current studies examine the concurrent validity of the M-CHAT in its ability to predict 18-month-olds' performance on theory of mind and word learning tasks. In Experiment 1, infants' understanding of…

We examined the impact of television viewing at ages 3 and 4 on vocabulary and at age 5 on executive functioning in the context of home learning environment and parental scaffolding. Children (N = 263) were seen in the lab when they were 3 years old and then again at ages 4 and 5. Parents completed measures assessing child television viewing and…

The present paper was written under the auspices of the interdisciplinary research group "Educational Processes, Competence Development, and Selection Decisions at Preschool and Primary School Age (BiKS)" (FOR 543), funded by the German Research Foundation (DFG). The surveys were conceptualised and supervised as part of the developmental…

The majority of early education programs promote children's learning through a mix of experiences in child- and teacher-managed contexts. The current study examined time spent in child- and teacher-managed contexts and the nature of children's experiences with teachers in these contexts as they relate to children's skill development. Participants…

Research Findings: Multitiered instructional frameworks are becoming a recommended approach for enhancing prevention and intervention efforts targeting early literacy and language skills. However, few studies to date have studied the feasibility of tiered oral language interventions before kindergarten; therefore, this pilot study explored the…

Findings on the relation of maternal verbal teaching strategies to children's effortful control (EC; i.e., self-regulation) are limited in quantity and somewhat inconsistent. In this study, children's EC was assessed at 18, 30, and 42 months (ns = 255, 229, and 209, respectively) with adults' reports and a behavioral measure. Mothers' verbal…

We examined the applicability of the Home Literacy Model in an orthographically transparent language (Greek). Seventy Greek children were followed from kindergarten until grade 4. In kindergarten they were tested in non-verbal intelligence, vocabulary, phonological sensitivity, rapid naming, and letter knowledge. The parents of the children also…
