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:…

Twelve 21/2-year-old children received adult verbal intervention selectively directed toward acquisition of either question forms or verb forms. Findings showed that children who received verb intervention acquired new verb structures while children who received question intervention acquired new forms of questions. (Author/JMB)

The development of relative clauses in child speech was investigated using an elicited production task instead of spontaneous speech samples. In an elicited production task, the context is manipulated so that a complex sentence must be used for communication. Thirty-six English speaking children from 3 to 5 years old were provided with contexts…

The comprehension ability of 36 children at three stages of telegraphic speech was assessed using active behavioral responses to declarative and imperative sentences. A significant increase in verbal and behavioral appropriateness with age was found for imperative and declarative forms. Results are compared with Shipley, Smith and Gleitman's…

This paper represents an effort to explain the language development of the child within the analytic frame of overtly observable data and without recourse either to mathematical models or to postulating hypothetical underlying forms. From longitudinal studies of two-year old children conducted by the author as well as from similar data reported in…

The verbal behavior of three children was sampled. The samples were analyzed to obtain a picture of three stages of the children's language development, specifically the interrogative structures. Each stage was about 4- or 5-months long, starting at the 18th to 28th month, depending upon the child's level of linguistic ability. The interrogative…

Command of transitivity permutations in Hebrew, where a change in verb-argument syntax entails a change in verb morphology, were examined in 30 children aged 2, 3, and 8. Findings have implications for the development of derivational morphology, item-based versus class-based learning, and the impact of lexical productivity and language-particular…

Comprehension of the quantifiers "some" and "all" was studied with 202 children, three to nine years old. Thirty-two quantifier sentences dealing with descriptions of circles and squares were presented to the children. Wooden objects were presented to some children to see if results were affected by the choice of abstract objects, but no…

From the standpoint of transformational grammar, this experimental work evaluates the extent to which children choose or fail to generalize their rules for the placement of the negative particles "not" and "n't." The subjects were eight three- and four-year-olds of middle-class background who had been producing sentences with…

Universal trends and individual variations in the language development process of the child are described and their relationships to beginning reading instruction are discussed. Child language begins with single word utterances to name things or to express needs and feelings. With a two-word utterance, the child can describe relationships more…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…

This paper describes part of a larger study dealing with syntax and semantics of the child's early speech about motion and location. It suggests that goal, defined as the point at which a motion ends and a resulting locative state begins, is the organizing principle for the semantics of motion and location. The data presented here are from two…

By age two, a child begins to form complex sentences by joining two or more sentences or by embedding one sentence into another. Formation of conjoined structures is a simpler process and emerges earlier than that of embedding structures. This paper attempts to answer the following questions: (1) Do children produce or understand embedding…

A study of overregularized use of verbs by two children over a period when they were 2 1/2 to 5 years of age shows overregularizations in two directions: non-causative verbs were used as causatives; and causative verbs were used non-causatively. According to terminology from logic, predicates were classified according to the number of noun-phrase…

A study was conducted to compare the relative performance on yes-no questions of bilingual and monolingual children and to discuss the relationship of semantic development and linguistic development, both in the bilinguals and monolinguals. Eighteen English monolingual, eighteen Japanese monolingual, and eighteen Japanese-English bilingual…
