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…

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…

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…
