Maternal input influences language development in children with Down syndrome (DS) and typical development (TD). Telegraphic input, or simplified input violating English grammatical rules, is controversial in speech-language pathology, yet no research to date has investigated whether mothers of children with DS use telegraphic input. This study…

Although children with Autism spectrum disorders (ASD) show significant variation in language skills, research on what type(s) of language profiles they demonstrate has been limited. Using growth-curve analyses, we investigated how different groups of young children with ASD show increases in the size of their lexicon, morpho-syntactic production…

The purposes of the study were to determine (a) the ability of two spontaneous language measures, mean length of utterance in morphemes (MLU-m) and number of different words (NDW), to identify African American preschool children at low and high levels of language ability; (b) whether child chronological age was related to the performance of either…

This is the first study to explore lexical and grammatical development in a deaf child diagnosed with Attention Deficit Hyperactivity Disorder, Inattentive sub-type (ADHDI). The child, whose family language was Spanish, was fitted with a cochlear implant (CI) when she was 18 months old. ADHDI, for which she was prescribed medication, was diagnosed…

In a study of the use of grammatical morphemes by 10 hearing-impaired children (5-15 years old) and 10 normal-hearing children matched on the basis of mean length of utterance, results revealed no significant differences in correct grammatical morphemes used and identical order of acquisition for both groups.

Production of grammatical morphemes was examined in free speech samples from 34 4-year-olds with history of slow expressive language development (SELD) and control group. Both the SELD children who had caught up in mean length of utterance by age four and those who had not had acquired fewer grammatical morphemes than controls, though acquisition…

Despite the common use of mean length of utterance (MLU) as a diagnostic measure, what it actually reflects in terms of linguistic knowledge is relatively unclear. This study explored the extent to which variance in MLU could be accounted for by a measure of expressive vocabulary and a measure of morphosyntax in a group of 44 typically-developing…

This study compared the relative effectiveness of imitative intervention and conversational recast language intervention applied to grammatical morpheme and complex sentences in 21 children with specific language impairment. The conversational procedure was found to require fewer presentations to first spontaneous use and to produce more…

Purpose: This study was conducted to examine whether the expressive language characteristics of typically developing (TD) children learning English as a second language (ESL) have similarities to the characteristics of the English that is spoken by monolingual children with specific language impairment (SLI), and whether this could result in the…
