Language acquisition may be one of the most difficult tasks that children face during development. They have to segment words from fluent speech, figure out the meanings of these words, and discover the syntactic constraints for joining them together into meaningful sentences. Over the past couple of decades, computational modeling has emerged as…

The present study aims at testing the two dominant hypotheses regarding the development of inflections and other functional categories namely the "Structure-Building Model" and the "Continuity Hypothesis" within the generative theory. According to the first view, functional categories are entirely absent in children's early grammars, which contain…

This study reports on the use of (c)overt subjects and subject-verb agreement in Hebrew in the spontaneous speech of a child, EK, acquiring Hebrew and English simultaneously from birth and of five slightly younger Hebrew monolingual controls. Analysis shows that EK's production of pragmatically inappropriate overt subjects is more than three times…

Replicates earlier studies and shows that children's ability to process syntactically well-formed sentences increases over the early school years. (Author/ED)

Four mothers and their language handicapped children (2-4 years old) were compared with four mothers and their normal language children. Mother-child interactions were tape recorded and analyzed for semantic, syntactic, and morphologic complexity. The normal language group had more sophisticated semantic, syntactic, and morphologic abilities than…

The progression through the developmental stages of the acquisition of interrogatives was analyzed. Data on use of the "what" interrogative were collected during play sessions from eight children at six-month intervals from the ages of 1;6 to 3 years. More than 2,400 children's interrogatives were recorded. It was demonstrated that…

This experiment was designed to investigate the possibility that young children use syntax to constrain and focus verb meanings in their interpretations of novel scenes and novel verbs. Subjects were 24 children, 12 males and 12 females, of 23 to 27 months, all raised in English-speaking homes. Their mean productive vocabulary was 240 words. A…

Between their second and fifth years, young children learn approximately 15 new words a day. For every word the child hears, he or she must choose the correct referent out of an infinite set of candidates. An important problem for developmental psychologists is to understand the principles that limit the child's hypotheses about word meanings. A…

The basis for acquisition of categories in child language was investigated. The early encoding of the distinction between mass and count nouns was examined to determine whether children categorize them on the basis of semantic type or syntactic regularities. An experiment was designed in which semantic and syntactic cues were in competition:…

Language samples were gathered from two children, from several weeks after the first birthday of each child to the beginning of the child's two-word period (approximately 10 months). The children were observed and videotaped every two weeks, to obtain 33 continuous minutes of tape. Analyses focused on the question of whether or not the child uses…

A set of six conditions for critically analyzing proposals in the various areas of language acquisition is developed and justified. These conditions are then applied to theoretical proposals in language acquisition literature. Proposals in the following areas are discussed and evaluated: (1) phonological development, (2) early lexical development,…

A distinction is drawn between pragmatic and semantic meaning and a supporting discussion is presented. The hypothesis is then stated, that there are cases where semantic meaning of an utterance is learned as an abstraction from pragmatic meaning. Data from two experiments on a group of 63 preschool children are presented which provide empirical…

This document reviews some of the indices of language development which have been constructed since the Anderson study of 1937. In addition to the findings of Anderson, the T-unit proposed by Hunt (1965), the measure of T-unit length and mean number of sentence-combining transformations per T-unit developed by O'Donnell, Griffin, and Norris…

The That-Complements test of the Test of Syntactic Abilities was administered to 93 deaf students (age 10-19 years) and 60 hearing students (age 8-11 years). (Author/SBH)
