Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…

This study characterized early language abilities in toddlers with autism spectrum disorders (n = 257) using multiple measures of language development, compared to toddlers with non-spectrum developmental delay (DD, n = 69). Findings indicated moderate to high degrees of agreement among three assessment measures (one parent report and two direct…

The aim of the article is to provide preliminary data on the use of auxiliaries and clitics in Serbian-speaking children with developmental language impairment. Two groups of children (a group of 30 children with developmental language impairment and a group of 30 typically developing children) aged between 48 and 83 months and matched on IQ took…

The structure of /s/-initial clusters is debated in developmental phonology. Pan and Snyder (2004) took the Government Phonology (GP) framework and proposed that production of /s/-initial clusters requires the positive setting of two binary parameters [+/-Branching rhyme (BR)] and [+/-Magic empty nucleus (MEN)] and the initial /s/ is treated as a…

The linguistic home environments of 10 language-delayed children and 10 linguistically normal children were compared using audiorecordings of parent-child dyads. Significant differences were found between the linguistic interactions of parents with a language-disordered child and parents with a linguistically normal child in all areas studied.…

The durational characteristics of novel words produced in repeated trials were evaluated in separate groups of children with, and without speech delay (SD). Children produced disyllabic novel words containing either a trochaic or iambic stress pattern. Results of acoustic analysis indicated a significant interaction between trial number and…

Speech samples of 14 normal 2-year-old children and 14 Down's Syndrome 5- to 12-year-old children were analyzed to investigate the structural complexity. Results from the Developmental Sentence Scoring procedure indicated that even when matched with normal children for mean length of utterance, Down's Syndrome Ss produced less syntactically…

This paper is a report of two studies of the relationship between intonation and syntax. An analysis of intonation was used to decide whether the pivot-like two-morpheme constructions of a one- and one-half-year-old girl were single lexical items or two separate lexical items. Further, the intonation contours connected with her linguistically…

Mongoloid children appear to be useful candidates for studying difficult methodological problems found in developmental research. They represent a subpopulation in which general development is markedly slower than in the normal child and in which language development appears to be more dependent on age than general intellectual development. This…

Drawing upon recent research findings and upon a case study of a child learning to talk and to read, the author outlines the important similarities in the development of both language and literacy. The characteristics of parent-child interaction which support language acquisition--semantic contingency, scaffolding, accountability procedures, and…

Thirteen institutionalized children from 4-1/2 to 14 years old, diagnosed as autistic, atypical, or childhood schizophrenic, were observed for three years to obtain a detailed description of their speech and language behavior. Case histories were assembled from available medical and psychological data. During a program of experimental relationship…
