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 of the acquisition of word meaning and the semantic features involved have been mostly confined to noun categories and polar adjectives. Investigation of the semantic categories underlying verb forms has implications not only for theories of child language acquisition but also for theories of semantic structure in general. Experimental…

The intent of this study was to examine the development of three aspects of preschoolers' private speech: coefficients of egocentricism, the extent to which speech regulates actions, and the syntactic and semantic structures of individual utterances. Forty-one randomly chosen preschoolers (26 females, 15 males) were placed in three age groups (3,…

This study discusses the nature of rhythm as it may apply to speech and language, reviews some of the literature on the development of rhythm, and presents some thoughts relating these findings to specific examples of children's speech. There is evidence to support the view that one need not look at the exact rhythm of any utterance, but only for…

A theoretical distinction is made between the growth of word meaning and the development of word sense in Vygotsky's terms. A recall from semantic memory task and the semantic differential were used to operationalize these two conceptions of meaning in a study of 72 children aged 5 to 10 years. Results replicated typical findings for the growth of…

This paper discusses the nature of language knowledge and the manner in which children come to acquire this knowledge. Among the topics discussed are language production and the ability to understand sentences never heard before, sentence formation, children's construction of rules, children's language creativity, language acquisition and age,…

The Children's Language Assessment-Situational Tasks (CLA-ST) was developed to collect language samples within a normally operating classroom. The language is taken on a cassette tape recorder, which is placed at the foot of a small table. At this table, in a committee setting, four children are engaged with a teacher in an activity similar to…

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…

This dissertation examines the principles of two current theories of first language acquisition and from them synthesizes a second language methodology. As a background to the problem of second language methodology, it is stated that the basing of second language methodologies on first language learning is currently being questioned and that the…

For the linguist interested in typology and language universals, this paper suggests the usefulness of a taxonomy of copula and copula-like constructions in the world's languages and the elaboration of hypotheses of synchronic variation and diachronic change in this part of language. For the linguist interested in child language development, the…

A linguistic analysis of five children's books, randomly selected from the "Modern Masters Books for Children" series, described the features of language found in books for beginning readers and demonstrated the value of structural analysis in reading research. Four linguistic measures were applied to each book: 1) the average number of words in a…

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…

Two experiments indicating that children's linguistic generalizational biases change from a semantically-based system to a syntactical-structural system provide evidence for a semantic-relational bias in children's early grammars and support the notion that children's generalizational biases shift from a semantic-relational basis to a…

Study of a one-year-old's earliest use of prepositions found that spatial oppositions ("up-down") were learned first, and used in non-prepositional senses prior to prepositional usage. "With,""by,""to,""for,""at," and "of" were learned later and used to express case relationships and more often misused and omitted than the earlier-learned…

Indicates that (1) children's violations decreased with age; (2) in the dyadic context, fathers assumed a more directive role in response to children's violations than did mothers; (3) there were no between-parent differences between parents regarding reactions to children's violations in the triadic context.
