Background: Children with speech sound disorder (SSD) are at increased risk of reading difficulties due to poor phonological processing skills. However, the extent to which children with SSD demonstrate weaknesses on specific or all phonological processing tasks is not well understood. Aims: To examine the phonological processing abilities of a…

Purpose: The purpose of this study was to explore the extent to which child- and therapy-level factors contribute to gains in speech sound production accuracy for children with speech sound disorders in receipt of school-based services. Method: Data were obtained from 126 kindergarten and first- and second-grade children currently in receipt of…

This study examined change in early language comprehension from 15 to 54 months for fifth-grade typical readers (n = 35), poor decoders (n = 11), or poor comprehenders (n = 16) from a nationally representative study of early child-care experiences. Changing measures of language comprehension were captured across early childhood for the 62…

This study examined the dimensionality of caregivers' child-directed talk and the association of child directed talk and children's language skills at age of 3 years in a sample of 63 low-SES dyads in low-SES homes. Exploratory factor analysis identified that caregivers' child directed talk is characterized by two dimensions: quantity and…

Purpose: Narrative skill represents a higher-level linguistic skill that shows incremental development in the preschool years. During these years, there are considerable individual differences in this skill, with some children being highly skilled narrators (i.e., precocious) relative to peers of their age. In this study, we explored the…

The current study was designed to determine whether classroom quality (i.e., the quality of teacher--child interactions) served as a mediator of peer effects with respect to preschool children's gain in language skills over an academic year. Participants were 670 preschool-age children (64.6% boys; "M" = 4 years, 4 months, "SD"…

Purpose: Narrative skill, a child's ability to create a temporally sequenced account of an experience or event, is considered an important domain of children's language development. Narrative skill is strongly predictive of later language and literacy and is emphasized in curricula and educational standards. However, the need to transcribe a…

This study applied multilevel modeling to examine the relationship between the percentage of children with mild/moderate disabilities in classrooms and children's language and literacy achievement over an academic year. The sample included 516 preschool children (mean age = 52.3 months, SD = 6.3) in 75 classrooms; 42% of the children had…

Drawing from a social network perspective, we examined the extent to which children with and without disabilities play with each other in preschool inclusive classrooms and identified malleable child characteristics that would support children forming these cross-status play interactions. A total of 200 children with disabilities and 301 children…

Read It Again! PreK (RIA) is a whole-class, teacher-implemented intervention that embeds explicit language and literacy instruction within the context of shared book reading and has prior evidence of supporting the language and literacy skills of preschool children. We conducted a conceptual replication to test its efficacy when implemented in…

Peer-effects research finds that preschool children's language growth is associated with classmates' skills and that children with disabilities especially benefit from classmates with higher skills. The current study estimates the amount of "peer language resources" individual children access through their classroom-based peer social…

Professional development (PD) is a potentially important mechanism for enhancing classroom practices and children's learning. In this large-scale randomized controlled trial, we examined the effectiveness of language and literacy PD, with and without coaching, offered at scale to early childhood educators (n = 546) across one state. Relative to…

Relative to the…

In this study, we identified child- and family-level characteristics most strongly associated with clinical identification of language disorder for preschool-aged children. We used machine learning to identify variables that best classified children receiving therapy for language disorder among a sample of 483 3- to 5-year-old children (54%…
