This dissertation investigates the acquisition of the passive. The apparent cross-linguistic delay of the verbal passive compared to other constructions suggests children's knowledge is somehow restricted, leading some to propose the difficulty arises because of syntactic maturation (Wexler 2004, Orfitelli 2012) or because of a heavy reliance…

The study indicated some superiority of the Bereiter-Engelmann Program, a structured, behavioristic method, over traditional language instruction methods. (MH)

Compares the many-perspectives account of lexical acquisition--which proposes that children learn to take alternative perspectives along with the words they acquire--to the one-perspective account--which proposes that children are at first able to use only one term to talk about an object or event. Provides evidence from a variety of sources that…

Compares the effects of language intervention over a one-year period on two groups of young children with delayed language: one group with cognitive skills markedly above their language level, and the other group with similar delays in cognitive and language skills. (28 references) (GLR)

The development of early vocalizations was investigated with 13 infants who had Down's syndrome and 27 infants developing normally, at bimonthly intervals from 4 to 18 months of age. Both groups demonstrated increased production of mature syllables over time as well as large variations in vocal development, both within and across groups and across…

In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant…

An epidemiological study of 205 children (3-4 years old) showed there to be a marked association between behavior problems and language delay. (Author)

Analysis of adult evaluation of children's linguistic output provides a basis for elaboration upon the work of McNeill (1970) and Brown (1970). When limited to the uttered words of a child paired with an utterance spoken at an earlier time, adults cannot judge the relative age of the children making those utterances; in fact, their predictions of…

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…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

The sentences in two first grade basal readers were categorized using Joan Tough's language function classification system to determine whether lower level basal readers allowed children to use their knowledge of language functions in reading. The range of language functions and language uses in the basals was compared to those that Tough found in…

Examines children's variation in rate, style, and sequence of grammatical development, within and across natural languages. Using a sample of English and Italian infants, concludes that while there are structural differences between English and Italian that could affect the order in which nouns and verbs are acquired, no differences were observed…

To determine the relative effectiveness of different methods of preschool educational intervention for disadvantaged children, comparisons were made of five programs whose levels of structure ranged from the traditional nursery school to a highly structured preschool. Subjects were 79 4-year-olds representing a wide range of ability levels.…

This study examined the correlation between speech, language, and hearing screening results and demographic or family structure. Participating were 733 children in day care, between 3 and 6 years old, representing diverse economic and racial backgrounds. Speech, language, and hearing screenings were completed in 1989, 1993 and 1995. The Denver…

The experiment described in this report investigates second language development and the possibility of determining various levels of language acquisition. The subjects involved are Japanese students learning English. The students are given the task of recalling English kernel sentences after hearing them once. The resulting sentences--the…
