Research Findings: I examined the long-term association between the lexical and acoustic features of maternal utterances during book reading and the language skills of infants and children. Maternal utterances were collected from 22 mother-child dyads in picture book-reading episodes when children were ages 6-12 months and 5 years. Two aspects of…

The simple view of reading posits that reading comprehension can be decomposed into a print-specific component (concerning decoding and sight word reading) and a language comprehension component (concerning verbal and metalinguistic skills not related to print). One might properly consider lexical skills, indexed by vocabulary measures, part of…

Language profiles of children with autistic disorder and intellectual disability (n = 36) were significantly different from the comparison groups of children with intellectual disability (n = 26) and typically developing children (n = 34). The group low-functioning children with autistic disorder obtained a higher mean score on expressive than on…

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples…

The purpose of this study was to use a mixed methods approach to learn about inadequate response to a year-long multi-tier response to intervention (RTI) model that allowed first-grade students to move up and down tiers. Participants were 156 students who received supplemental intervention services during a larger multi-tier RTI study involving…

Sixty-one preschool children and their parents and teachers participated in a cross-sectional study of the social-emotional correlates of emergent literacy skills. The children's emergent literacy skills were assessed with the standard language and literacy tests: "Expressive Vocabulary Test, Peabody Picture Vocabulary Test" (third…

The current study examined the role of basic language skills for individual differences in preschoolers' understanding of causal connections. Assessments of basic language skills, expressive vocabulary, phonological processing, and receptive language comprehension were examined in relation to the production of causal connections in a storytelling…

Autism spectrum disorders (ASD) are associated with many different levels of language and social impairment, differences in levels of cognitive impairment, varying levels of aberrant behavior, and discrepancies in the presence or amount of restrictive and repetitive behavior. The heterogeneity found within the ASD population is coupled with…

Background: Girls with fragile X syndrome (FXS) have a wide range of cognitive and language abilities. The range of language outcomes experienced by girls with FXS, however, has been relatively unexplored. The purpose of this exploratory study was to examine receptive and expressive language, with a focus on vocabulary and syntax, in a group of…

Purpose: This study examined the longitudinal effects of social behaviors in predicting phonological awareness outcomes in 4-year-old children. Method: One hundred two children (52 boys, 50 girls) were recruited from 11 schools serving low-income neighborhoods in a large metropolitan city and were assessed at the beginning and end of the preschool…

Objectives: To compare differences in autism between Hispanic and non-Hispanics. We also examined the relationship between multiple language exposure and language function and scores of children. Methods: The Childhood Autism Risks from Genetics and the Environment (CHARGE) study is an ongoing population-based case-control study with children…

Self-regulation emerges throughout early childhood, and predicts later success in socially and cognitively challenging situations. Vygotsky proposed that symbols, particularly words, serve as mental tools to be used in service of self-regulation. Cross-sectional research indicates a positive but inconsistent association between language and…

This study evaluated the effects of Adapted Reciprocal Teaching (ART) on the receptive and expressive flight-word vocabulary of 1st-grade students. During ART, classroom interactions produced narrative contexts within which students assumed responsibility for applying new flight words in personally meaningful ways. Students in the control group…

This study characterized early language abilities in toddlers with autism spectrum disorders (n = 257) using multiple measures of language development, compared to toddlers with non-spectrum developmental delay (DD, n = 69). Findings indicated moderate to high degrees of agreement among three assessment measures (one parent report and two direct…

Objective: This article examines the form and function of spontaneous communication and outcome predictors in nonverbal children with autism following classroom-based intervention (Picture Exchange Communication System [PECS] training). Method: 84 children from 15 schools participated in a randomized controlled trial (RCT) of PECS (P. Howlin, R.…
