Recognizing early risk markers in young children with autism spectrum disorder (ASD) is critical for timely diagnosis and intervention. The purpose of this study was to extend previous findings regarding language milestones to a longitudinal design, in which ages of expressive language milestones (i.e., first words, first phrases) could serve as…

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,…

Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6-36 months. Children were grouped as: ASD…

It is well established that language development in children with autism is disturbed in a number of ways, and evidence is accumulating that their emerging linguistic skills may be related to interactive competences such as joint attention, imitation and certain aspects of play as has been found in normally developing children. The present study…

Expressive vocabulary was studied in 130 children (ages 1 to 5 years) with Down syndrome. Although there was continuous growth in expressive referential vocabulary from birth through 5 years, age 5 was found to be an important developmental marker for multiword combinations and grammatical vocabulary.

The first of three booklets in a series designed to help parents of handicapped children birth to 5 years old focuses on the communication process. A chart lists developmental milestones for both expressive and receptive language. Learning processes for communication (such as imitation, sensory knowledge, and memory) are reviewed. The bulk of the…

Spoken language in 330 children with Down syndrome (ages 1-5) and 336 normally developing children (ages 1,2) was compared. Growth trends, individual variation, sex differences, and performance on vocabulary, pragmatic, and grammar scales as well as maximum length of utterance were explored. Three- and four-year-old Down syndrome children…

Discusses how single-word usage reflects two stages in child language development. Early words express internal states and share none of the corresponding semantic features of these words in adult language. Later words approximate the use of adult language and share standard semantic features of adult indicative words. (JMF)

The study evaluated whether specifically language impaired (SLI) children (N=6 and ages 5-8) manifested atypical or normal but delayed development in their interpretation of PRO (an empty pronomial element which has also been termed "a missing complement subject"). Language samples were taken and analyzed twice over a 9-12 month period. Among…

This study evaluated an Extended Optional Infinitive theory of specific language impairment (SLI) in children, which suggests that SLI children omit finiteness markers longer than do normally developing children. Comparison of 18 SLI 5-year olds with 2 normally developing groups (ages 5 and 3) found that SLI subjects omitted finiteness markers…

A study involving 82 children with low vision evaluated the new developmental age levels and psychometric properties for the Reynell-Zinkin scales. The usefulness of age levels of the Reynell-Zinkin scales is discussed in relation to the aim of the scales, which is to have guidelines for assessment and developmental advice. (Contains references.)…

The profiles and developmental trajectories of adaptive behavior were cross-sectionally examined in 80 children with Down syndrome ages 1 to 11.5 years using the Vineland Adaptive Behavior Scales. Profile findings indicated a significant weakness in communication relative to daily living and socialization skills. Within communication itself,…
