The existence of a developmental sequence for the acquisition of specific complex syntactic structures in English was investigated through an analysis of eight studies of Danish subjects. The studies involved Danish speaking subjects acquiring English as a second language at ages 7-10, 13, and 18. The evidence from these studies demonstrate a…

To determine the normal sequence of the development of Spanish phonology and Spanish grammatical patterns in the speech of native Spanish speakers, ages 2-5, a study of the acquisition of interrogative formation was undertaken. Two male and two females from each of nine age intervals between two and five were selected as informants; all were…

To the question of whether Chomsky's hypothesized Language Acquisition Device (LAD) in young children is an adequate and feasible model of language acquisition, this paper answers that LAD should be reformulated so as to include semantics; that "informant presentation" rather than "text presentation" is responsible for language…

The study summarized in this paper deals with the grammatical analysis of the spontaneous speech of approximately 150 children who are classified as mentally disabled; educable (I.Q. range 50-80). The performance of these mentally disadvantaged children is compared with the performance of 200 normally developing children by using a clinical…

Discusses the influence a first language can have on the acquisition of a second language. Includes some tentative proposals on the interaction of prior first-language knowledge and the creative construction process. (EKN)

This in-process report discusses the writing development of a student from first grade through mid-eighth grade. An analysis of the student's T-unit length averages from third grade to mid-eighth grade reveals a leap of syntactic complexity from the fifth to the sixth grade. Among the other findings are the following: two modes of…

Language training for the non-verbal or language delayed child should utilize feedback to reinforce correct responses and should closely follow the syntactical development of normal children. The two basic areas of language training are receptive and expressive. Receptive language training includes attending and responding, following single phase…

Research is being conducted to determine the factors behind linguistic retardation in children. A first question raised was whether the linguistic system of the deviant child is qualitatively different from that of a normal child. A matching-up of deviant and normal children according to linguistic level suggests that the onset of base syntax may…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

The syndrome of childhood autism is typified by major abnormalities in language development, yet there are few systematic descriptions of autistic children's linguistic systems. This paper represents the beginning of a comprehensive investigation of the language of verbal autistic children and concentrates on comparing the syntax used by ten…

This paper describes the linguistic development of two hearing sons of deaf parents. Both were exposed to an early language environment different from that of the average hearing child. At the start of the study, the boys were aged 3 years, 9 months, and 1 year, 8 months, respectively. When first observed, the older child performed well below age…

In any successful conversation, a speaker must select both what is said and how it is said on the basis of various estimates of the listener's abilities, knowledge and interests. Most research on linguistic input to children has focused on the tendency of speakers to simplify their speech for the younger listener. Little attention has been paid to…

Infant bilingualism can be defined as a child being exposed to two or more languages from birth. Because of the dearth of first-hand research on the effect of a bilingual environment on a child's speaking patterns, parents from multilingual backgrounds raised their daughter in a bilingual environment, German and Spanish, in England. They speak to…
