Comprehension of relative clauses was assessed in 10 Hebrew-speaking school-age children with syntactic SLI and in two groups of younger children with normal language development. Comprehension of subject- and object-relatives was assessed using a binary sentence-picture matching task. The findings were that while Hebrew-speaking children with…

Building on the visual orientation of individuals with deafness, and employing such techniques as visualization and directionality, a computer-based method of communicating syntactic knowledge to deaf students was designed. "The Question Game" was designed to model and help students build yes-no questions and WH questions (who, what,…

An obstacle in Natural Language understanding is the existence of lexical gaps, i.e. words or word senses that are not in the lexicon of the system. This thesis describes the implementation of MURRAY, a learning mechanism which infers the properties of a new lexical item from its syntactical environment and infers its meaning based on context and…

Developmental trends in the effects of expectations regarding agent/action matches on judgments of sentence acceptability were investigated. Five sentences reflected expected relations ("harmonious") and five contradicted them ("contrary"). Twelve subjects each were in grades 4 through 8 during year 1; the same 60 subjects…

Studies on the acquisition of relative clauses are reviewed. Two polarities among a variety of possible approaches are: Slobin's (1971) study that emphasizes acquisition process and learning strategies, and studies like Sheldon's (1974) that emphasize the linguistic structures involved. Early proposals that children experience more difficulty in…

The years after children demonstrate comprehension of particular syntactic structures have received little attention. What happens in language development after mastery is achieved? Are children then like adult speakers in judging the acceptability of grammatical structures? Questions addressed in this research were: Will older children and young…

The purpose of this study was to investigate the linguistic differences in the spontaneous speech of language-deviant children in two very different situations. Spontaneous speech samples of eleven five-year-old language-deviant children were obtained from: (1) the traditional adult-child therapy situation using appropriate stimulus materials; and…

In speaking a child sometimes makes constructions in which a sequence of separate utterances expresses a semantic relation not expressed by either utterance. These "vertical constructions" are the main point of this study. Previous studies of construction in child language have largely dealt with sentences. In this study, sentences are…

The speech of a 2-year-old monolingual Estonian child was studied over a period of six months. The child's initial and medial consonants and clusters were examined and charted to highlight her difficulties. Stops and nasals were easier than fricatives and sonorants; by 1 year 7 months the labials were essentially mastered; fricatives were more…

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…

Previous studies dealing with the age at which children acquire constituent order preferences have been in conflict. This study was designed to determine if children with normal language development demonstrate constituent order preferences as early as age three and one-half, or a mean age of four years, one month. To test this competency, an…

The purpose of this series of four studies was to precisely describe the code and dialect features of the speech of both lower class Negro children and middle class white children. In the first study, 16 white middle class (WMC) children were compared to 16 Negro lower class (NLC) children on both an imitation and a comprehension task. The WMC…

Previous studies have defined the earliest stage of child language to be the stage at which an uninitiated speaker of adult language can understand sentences spoken by the child. Upon the examination of the language of one child, aged 1 year and 7 months, it became evident that she could talk, even though it was equally evident that she didn't use…

The language a child learns from and attends to is the speech of significant persons in his world, addressed to each other and to him. As the child gradually participates in this social interaction he learns communicative competence, i.e., the nonconscious, tacit knowledge that underlies speech behavior--knowledge of both the language and the…

The syntactic properties of the child's language are studied. Within the framework of transformational grammar, the rules of syntax can be divided into three types: base- or phrase-structure rules, transformational rules, and morphological rules. Each of these rules is discussed. It is stated that the one process that appears to characterize each…
