Results showed that 12 language disordered children (four to six years old) selectively marked new information in verbal communication, just as normal children do. Language disordered and normal children, furthermore, manifested the same developmental sequence of strategies for deemphasizing old information. (Author/CL)

Communication samples were collected from 15 normally developing children (ages 11-27 months) during the prelinguistic, single-word, and multiword stages, using both structured and unstructured contexts. Significantly more requests were used during the structured context, but no significant difference was found between the numbers of comments used…

The persistence of individual differences in phonological development of 10 normally developing children observed at age one and again at age three was studied. The children differed considerably in rate of vocabulary acquisition and relative phonological maturity and also in their general approach to learning. (Author/JDD)

The study investigated the ability of 60 children, age 6-8, to monitor grammaticality in the past progressive, perfect progressive, and perfect verb forms. Children achieved a significantly higher rate of accurate judgments monitoring grammatical forms than ungrammatical forms. Context surrounding ungrammatical verb forms and child's age…

The relationship between interactive play and the frequency of related responding to comments was investigated within the dyadic interactions between a language impaired 4-year-old and 4 normal language users. While the frequency of related responses was variable for the subject, the frequencies of related responses of normal children were…

Children (ages 9-13) with language-learning disabilities were administered 5 types of verbal analogies: synonyms, antonyms, linear order, category membership, and functional relationship. Subjects performed worse than mental age-matched children on all types of analogies and performed worse than language age-matched children on all types except…

This investigation studied (1) the acquisition and proportion of correct usage of consonants of Japanese and American children, (2) the consonant substitutions of children developing normal language and of children with articulation problems, and (3) confusion in adults' recall of consonants. A system of distinctive features (gravity, diffuseness,…

Vowel production of a 14-month-old girl was studied over a 6-month period. Sixty percent of the vowels were produced correctly. A complex pattern of vowel preferences and errors was partially related to prespeech babbling preferences and strongly related to word structure variables (monosyllabic versus disyllabic). (Author/JDD)

This study examined Quick Incidental Learning (QUIL) of novel vocabulary by 88 primary school-age children with and without specific language impairment (SLI). Among normally developing children, results documented a robust ability to learn words in the early school years. Children with SLI demonstrated significantly less word-learning ability…

Language abilities from age 2-5 were studied in 4 children with early language delays. Deficits became milder and more selective, with normal or nearly normal speech/language proficiency by age 60 months. But at 3-year follow up, 3 of the 4 cases were severely reading disabled. (Author/JDD)

Linguistic and cognitive development of 26 premature and 27 full-term infants was studied longitudinally over the first 3 years of life. Patterns of lexical and cognitive development did not differ substantially between groups, nor did standard language test measures indicate differences at the study's end except with very low birthweight…
