Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children's language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom…

Background: Late language emergence is a risk indicator for developmental language disorder. Parent-implemented early language intervention programmes (parent programmes) have been shown to have positive effects on children's receptive and expressive language skills. However, long-term effectiveness has rarely been studied. Additionally, little is…

Purpose: This study reports age 5 morphology and syntax skills in late talkers identified at age 2 (n = 34) and typically developing comparison children (n = 20). Results: The late talkers manifested significant morphological delays at ages 3 and 4 relative to comparison peers. Based on the 14 morphemes analyzed at age 5, the only significant…

Direct instruction is often necessary to develop language or expand language use in individuals with language delays. Previous research has begun to identify certain training conditions that result in more efficient use of instructional time devoted to language development. Specifically, incorporating mands into the instructional arrangement,…

Purpose: The aim of this study was to investigate the language outcomes of 7-year-old children with and without a history of late language emergence at 24 months. Method: One hundred twenty-eight children with a history of late language emergence (LLE) at 24 months and 109 children with a history of normal language emergence (NLE) at 24 months…

This article reviews research on speech and language abilities in people with cri du chat syndrome (CCS). CCS is a rare genetic disorder, with an estimated incidence between 1 in 15,000 and 1 in 50,000 births, resulting from a deletion on the short arm of chromosome 5. In general, individuals have delayed speech and language development, and some…

Background: Previous studies of outcome for children with early language delay have focused on measures of early language as predictors of language outcome. This study investigates whether very early processing skills (VEPS) known to underpin language development will be better predictors of specific language and social communication outcomes than…

Interactions between phonology and syntax were inspected in continuous speech samples, from 30 speech-delayed children. Results indicated that two-thirds of the Ss displayed evidence of overall syntactic delay, whereas half showed some limitations in use of phonetically complex morphophonemes, their performance in that area being below the level…

The study examined whether 10 developmentally delayed children (3:3 to 5:4 years old) would demonstrate superior comprehension for restricted, syntactically incomplete as compared to reduced, syntactically complete forms. The five children functioning at late linguistic stage I demonstrated better comprehension than the early stage I children for…

The relationship between language and symbolic gesture was studied in nine children (ages 18-32 months) who were in the lowest 10 percent for language production for their age. Subjects performed like language-matched controls on a lexical production task. On a syntax-related task, they performed like age-matched and significantly better than…

Comparison of dysphasic children (N=8) with control children found that the dysphasic children's language development was both delayed and deviant, and that the children's deviant syntax structures were the result of insufficient language processing and could not be traced back to structural characteristics of the sentences used by their mothers.…

Mean length of utterance (MLU) of 15 Down's Syndrome children, aged 2-12, was examined and found to correlate highly with chronological age despite the children's language delays, at least up to MLU 3.00. MLU also predicted complexity and diversity of bound morphemes and major syntactic structures from MLU 1.00-3.50. (Author/JDD)
