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…

Grammatical deficits (e.g., missing feature, surface account, and missing agreement) reported for children with specific language impairment (SLI) were evaluated in spontaneous language transcripts from 108 preschool children. Results indicated that children with SLI do control number marking but find number agreement across clausal boundaries…

This article explores 46 deaf college students' knowledge of English wh-question formation in the context of government-binding theory and an associated learnability theory. Results of two learnability tasks revealed that, despite years of exposure to English language input, many deaf learners had not internalized the positive evidence required to…

This study, involving 26 children (ages 44-70 months) with impairments in grammar and phonology, found that children receiving either a clinician-administered or parent-administered intervention showed gains in expressive grammar, but there were no indirect effects on subjects' phonological production. Language intervention approaches for young…

This study, with 30 language learning-disabled, reading-disabled, and normal primary school children, found that clause structure complexity, fluency, and grammatical and phonemic accuracy tended to be highest when children were discussing absent referents, providing explanations and stories, and giving unshared information. These effects were…

Spontaneous speech samples from 10 Swedish children were analyzed grammatically. The five subjects (age five) with specific language impairment (SLI) differed from controls in their more restricted usage of word order patterns and number of grammatical errors. Their speech also showed frequent omissions of grammatical morphemes. Results suggest…

Self-initiated repairs produced by 14 normal-language and 14 language-disordered children (ages 8-12) during a story retelling task are described. No group differences were found for grammatical repairs, text meaning repairs, or cohesive repairs relating to text meaning. Differences were significant for success of cohesive repair attempts and…

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…

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…

This article describes the EpiSLI diagnostic system for identifying specific language impairment in kindergarten children for the purpose of epidemiological research. The system employs five composite scores representing norm-referenced performance in three domains of language (vocabulary, grammar, and narration) and two modalities (comprehension…
