Previous research in the area of children's knowledge of number agreement morphology has yielded mixed results. Some researchers have found evidence for sensitivity to agreement morphology at as early as 16 months, while others report that children do not comprehend number agreement morphology until as late as five or six years old. Studies of…

This report describes a project that uses existing data sets to describe the population of students with significant cognitive disabilities and known or suspected dual sensory loss. It includes students with suspected dual sensory loss because students with significant cognitive disabilities are reported to have unidentified sensory loss (Erickson…

To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross-sectional study, on an eye gaze measure of receptive language that measured how…

This study explores morpho-syntactic reading comprehension in 19 Spanish children who received a cochlear implant (CI) before 24 months of age (early CI [e-CI]) and 19 Spanish children who received a CI after 24 months (late CI [l-CI]). They all were in primary school and were compared to a hearing control (HC) group of 19 children. Tests of…

In light of evidence that receptive language may be a relative weakness for individuals with autism spectrum disorder (ASD), this study characterized receptive vocabulary profiles in boys with ASD using cross-sectional developmental trajectories relative to age, nonverbal cognition, and expressive vocabulary. Participants were 49 boys with ASD…

Sub-optimal language development is associated with the metabolic disorder galactosaemia (GAL). Some children with GAL are identified with language impairment from the initial stages of language learning, but a subset of children may exhibit disrupted developmental gains in speech and language skill after a period of age-appropriate skill…

Relatively little is known about trajectories of autism severity using calibrated severity scores (CSS) from the Autism Diagnostic Observation Schedule, but characterizing these trajectories has important theoretical and clinical implications. This study examined CSS trajectories during early childhood. Participants were 129 children with autism…

Purpose: The author followed 56 internationally adopted children during the first 3 years after adoption to determine how and when they reached age-expected language proficiency in Standard American English. The influence of age of adoption was measured, along with the relationship between early and later language and speech outcomes. Method:…

This article documents differences in cognitive development, as measured by the Peabody Picture Vocabulary Test (PPVT), between children from households with high and low socioeconomic status (SES) in two different phases of early childhood in four developing countries. A large number of potential mediators, such as urban residence, preschool…

Some reports suggest that there is an increase in the number of children identified as having developmental language impairment (Bercow, 2008). yet resource issues have meant that many speech and language therapy services have compromised provision in some way. Thus, efficient ways of identifying need and prioritizing intervention are required.…

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3-4 years old, n = 105), kindergarten (5 years old, n = 97),…

This article reports a post hoc analysis conducted as part of a larger study in which 61 typically developing, 3-, 4-, and 5-year-olds were assessed in phonological awareness (PA), vocabulary (i.e., receptive, expressive, and definitional), and grammatical skill at baseline and 3, 6, and 9 months later. The larger study's purpose was to shed light…

Children who have not developed speech tend to use gestures to communicate. Since gestures are not encouraged and suppressed in the Indian traditional context while speaking, this study focused on profiling the developing gestures in children to explore whether they use the gestures before development of speech. Eight normally developing…

Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

This article presents receptive and expressive American Sign Language skills of 85 students, 6 through 22 years of age at a residential school for the deaf using the American Sign Language Receptive Skills Test and the Ozcaliskan Motion Stimuli. Results are presented by ages and indicate that students' receptive skills increased with age and…
