Background: Children who have reached the age of 2 years without having acquired a 50-word vocabulary and/or who use no word combinations are referred to in the literature as "Late Talkers". Research has not yet identified the factors that cause slow development of expressive language; in particular, relatively little research has been carried out…

This study compared language skills in a group of very low-income toddlers with those of a middle-income sample matched on age and sex. The assessment instrument used was the MacArthur Communicative Development Inventory for toddlers, a parent report form. Scores for low-income group were strikingly lower on three key indices evaluated: size of…

This paper utilizes Toulmin's original framework to analyse over 400 answers given by 11-year-olds to a question on a written mathematics test. The question required children to say whether a given statement is true and give a written explanation. Categorizations of answers are developed from the data and examined, suggesting that many children…

Examines whether manually coded English (MCE) sign language systems are learnable. Reading achievement and expressive English skills of deaf students educated using only a MCE sign system were examined. Deaf students had expressive English skills comparable to hearing students in respect to syntactical and lexical skills but were deficient in…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

The present work investigated cognitive, linguistic and narrative abilities in a group of children suffering from Duchenne Muscular Dystrophy, an allelic X-linked recessive disorder caused by mutations in the gene encoding dystrophin. The patients showed mildly reduced IQ with lower Verbal than Performance Intelligence Quotient and were mildly…

This study assessed the relation between pre-intervention variables (cognition, socialization and communication) to outcome in young children with autism. Method: Twenty five children with autism (20-32 months) were enrolled in intensive behavior intervention. The children were divided into groups based on their IQ scores and on the severity of…

There has been little research comparing the nature and contributions of language input of mothers and fathers to their young children. This study examined differences in mother and father talk to their 24 month-old children. This study also considered contributions of parent education, child care quality and mother and father language (output,…

This study compared pragmatic skills of 5 children (ages 4-6) with specific language impairments (SLI) and their younger siblings matched for mean length of utterance. Analysis of communicative acts on three levels (social interchange, speech act, and conversational) indicated comparable performance within sibling pairs, but SLI children…

Background: Recent research has shown that phonological awareness therapy can improve speech production in children with expressive phonological disorders. This approach may be appealing to clinicians as the therapy may also benefit the children's general phonological abilities and lead to gains in their literacy skills. Aims: To examine the…

Background: Though the Down syndrome behavioural phenotype has been described as involving relative strengths in visuo-spatial processing and sociability, and relative weaknesses in verbal skills and motor planning, the early emergence of this phenotypic pattern of strengths and weaknesses has not yet been fully explored. Method: In this study, we…

This study examined repair strategies used by boys with language impairments, in response to clarification requests following conversational breakdowns. Five subjects, aged four-five, were compared with five age-matched controls and five controls matched for verbal competence. Results showed that all three groups overwhelmingly used revisions to…

Twenty-three normal adults and four closed head-injured (CHI) adults with a high level of language recovery retold and generated stories. The two tasks differentially influenced the performance of both groups. The two groups differed in measures of cohesiveness and story grammar only in the story generation task. (Author/JDD)

Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3 and 4 were investigated in 34 late talkers with normal receptive language and in 16 typically developing comparison children matched on age, socioeconomic status, and nonverbal ability. Late talkers made greater gains than comparison children between…

Although shy children speak less in social situations, the extent to which their language skills fall behind those of their more outgoing peers remains unclear. We selected 22 temperamentally shy and 22 non-shy children from a larger group of 400 4-year-old children who were prescreened for temperamental shyness by maternal report, using the…
