Reading comprehension is contingent on both oral language comprehension and word-level reading ability, skills that are thought to be intrinsically related in the early school years. However, while previous studies examining bidirectional relationships among oral vocabulary and reading development have generally found an association between word…

Purpose: Manual sign is a common alternative mode of communication taught to children with childhood apraxia of speech (CAS). Gesture use is positively related to later increases in vocabulary and syntactic complexity in typical development, but there is little evidence supporting the use of manual sign for children with CAS. We sought to identify…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

This study compared simultaneous prompting with an error correction procedure for teaching three children diagnosed with autism spectrum disorder expressive labels. Using a parallel treatment design nested within a multiple probe design, the researchers taught each participant how to expressively label pictures of sports teams or cartoon…

The ability to narrate past personal events is important for classroom participation and socio-emotional wellbeing. Although school-age children with Down syndrome show significant challenges producing personal event narratives, there is little research to guide personal narrative intervention. This study used a single subject experimental design…

Background & aims: Individuals with non- or minimally verbal autism (nvASD) are primarily characterized by a severe speech production deficit, with speech limited to no or only a few words by school age. Significant unclarity remains over variability in language profiles across the lifespan, the nature of the language impairment seen, and…

Purpose: Previous research has demonstrated that typically developing children, verbal children with a diagnosis of autism, children with Down syndrome, children with developmental language disorder, and children with dyslexia can all benefit from orthographic support during word learning tasks. This study sought to determine if minimally speaking…

In many autistic children, speech onset is delayed and expressive language emerges after 3 years of age. We qualitatively and quantitatively describe oral productions of autistic preschoolers, including many non- or minimally speaking, recorded during interactions with a caregiver and with an experimenter. Data clustering on manually coded oral…

Purpose: Little is known about the specific nature of language abilities of autistic adolescents and young adults with language impairment (LI), limiting our knowledge of developmental trajectories and ability to develop efficacious speech/language supports. An important first step is establishing proof of concept of identification of LI in this…

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

Preschoolers can learn vocabulary from educational videos, but children from low-income backgrounds often do not learn as effectively as their higher income peers. We investigated whether adding attention-directing cues to media (Study 1) and slowing the pacing of media (Study 2) supported vocabulary learning for preschoolers from low-income…

The purpose of this exploratory study was to examine the longitudinal, bidirectional relations between receptive and expressive Spanish and English language and internalizing and externalizing behavior problems in a sample of 97 preschool children from Spanish-speaking, homes who were enrolled in a U.S. Head Start program. Eight cross-lagged path…

Purpose: This longitudinal study assessed continuity and stability of productive language (vocabulary and grammar) and discourse features (turn-taking; asking and responding to questions) during mother-child play. Method: Parent-child language use in 119 Spanish-speaking, Mexican immigrant mothers and their children at two ages (M = 2.5 and 3.6…

Purpose: Several studies have reported that "useful speech" at 5 years of age predicts outcomes in individuals with autism spectrum disorder (ASD), but this skill has been vaguely defined. This study investigates which specific aspects of expressive language in children with ASD best predict adult language and communication outcomes.…

Vocabulary knowledge is essential for successful language learning. However, little is known about young learners' vocabulary learning in a Thai EFL context and the teaching methods that facilitate vocabulary learning. The current study examined whether songs and total physical response (TPR) can facilitate preschoolers' vocabulary acquisition in…
