This study assessed the utility of a brief assessment (the Peabody Picture Vocabulary Test-4th Edition; PPVT4) as a proxy for verbal IQ (VIQ) in large-scale studies of autism spectrum disorder (ASD). In a sample of 2,420 proband with ASD, PPVT4:IQ correlations were strong. PPVT4 scores were, on average, 5.46 points higher than VIQ; 79% of children…

This study identified patterns of classroom and family experiences and developmental outcomes for young children in segregated early education. This study is based on data from a high-quality early education program serving young children from low-income households in 19 schools across the U.S. The sample included 1,521 children during the…

Research Findings: A social validity measure was used to examine 56 bilingual preschool teachers' perceptions and acceptability of an interactive shared book reading vocabulary intervention implemented in English with Spanish-speaking preschool children (N = 334) in a dual language program model. Social validity outcomes indicated that bilingual…

The current study investigates how second language (L2) listening comprehension is associated with three dimensions of L2 vocabulary knowledge: size, depth, and fluency. Vocabulary knowledge tests administered to 290 participants measured L2 auditory vocabulary size, depth, and fluency. Afterward, participants took an International English…

We assessed the simple view of reading as a framework for Grade 3 reading comprehension in two ways. We first confirmed that a structural equation model in which word recognition, listening comprehension, and reading comprehension were assessed by multiple measures to inform each latent construct provided an adequate fit to this model in Grade 3.…

This study examined benefits of connecting meaning, speech, and print in vocabulary learning for kindergarten English learners. Students screened eligible with limited English proficiency were randomly assigned to two instruction conditions. Both groups received direct instruction in high frequency root words. One condition featured added…

Background: Although a large body of research has investigated teachers' reading-related knowledge and associated pedagogical practices, comparatively little is known about these factors in parents. Therefore, the present study examined the association between parental reading-related knowledge and feedback during child-to-parent reading. Methods:…

We examined the relations between teachers' use of comments during book reading sessions in preschool classrooms and the vocabulary growth of children with low and moderately low language ability. Using data from a larger randomized controlled trial, we analyzed comments defined as utterances that give, explain, expand, or define. Comments were…

Research Findings: This article examines whether time spent in free choice and teacher-directed activity settings within preschool was associated with indicators of school readiness and the extent to which children's learning was associated with the quality of teachers' behavior within these settings. Participants were 325 preschool teachers and…

In this study, we explore the interconnectedness between children's creativity, social play, and language abilities. The participants were 225 (109 girls, 116 boys) preschool children, from diverse European American, African American, and Hispanic ethnic heritages. We assessed the children in three ways. First, each child completed the Goodenough…

The purpose of this study was to investigate whether the relation between morphological awareness on reading comprehension is moderated by multisyllabic word reading ability in fifth-grade students ("N" = 169, 53.7% female, 65.2% minority status, 69.2% free/reduced lunch status), oversampled for poor reading skill, when controlling for…

Play is a significant aspect of preschool curricula. We report two studies that examine the effects of play-related variables: length of free play, type of language instructional approach, degree of structure of free play, and amount of teacher involvement in communication with peers. For each study, we target three dependent variables: rate of…

This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

We examined data from an 18-week kindergarten vocabulary intervention study to determine whether treatment outcomes had differential effects that favored English language learners (ELLs) or English-only learners (EOLs) and whether the relationship between initial English general receptive vocabulary knowledge and response to vocabulary…

In this study, the relations among a range of literacy-related home practices and children's acquisition of language and literacy at the outset of preschool are examined in a sample of linguistically diverse children from low-income families in the United States. Specifically, the study focuses on sources of variation found in mother-child…
