Examined children's language acquisition by compiling a record of one English boy's utterances from age four to six. The record revealed the boy's interest in the meaning of words, knowledge of grammar, interest in non-English words, explorations of the connections between what people say and what they mean, and understanding of the role of…

Reviews book on the current state of psychological semantics for researchers in language development. Notes points of agreement among contributors, including: study of semantics has been too oriented toward substance nouns; assigning novel words to real objects or events is more difficult using verbs than nouns; and syntax is more integrally…

In learning the meaning of a new term, children need to fix its reference, learn its conventional meaning, and discover the meanings with which it contrasts. To do this, children must attend to adult speakers--the experts--and to their patterns of use. In the domain of color, children need to identify color terms as such, fix the reference of each…

Children are able to take multiple perspectives in talking about entities and events. But the nature of children's sensitivities to the complex patterns of perspective-taking in adult language is unknown. We examine perspective-taking in four- and six-year-old Tamil-speaking children describing placement events, as reflected in the use of a…

This article focuses on the meaning of nonfinite clauses ("root infinitives") in Dutch and English child language. I present experimental and naturalistic data confirming the claim that Dutch root infinitives are more often modal than English root infinitives. This cross-linguistic difference is significantly smaller than previously assumed,…

Two experiments investigated 4- to 5-year olds' understanding of semantic relations and methods for incorporating new words into their lexicon. In one experiment, 24 children were shown a picture of a container and told that an object called "X" was hidden inside it. Children were asked questions about the object X and about…

An investigation of children's metalinguistic and metacognitive competencies examined children's sensitivity to the verbs of cognition in two related studies using a task designed to measure mastery of verbs of saying and meaning. In the task the children hear six short stories, each ending with a statement containing one of the verbs…

A case study of a 2-year-old progressing normally in speech development provides evidence of suprasegmental marking of the plural, thought to be adopted only in language-impaired children. Acoustic analyses of the durations and intensity of elicited words indicate that the child had adopted a suprasegmental strategy for marking the singular/plural…

Relationships between "combinatorial" abilities in language, symbolic play, blockbuilding, and non-semantic action sequences were explored in a study of 30 infants between 82 and 91 weeks of age. Subjects were observed in a laboratory playroom setting for approximately 45 minutes. During this time, a number of tasks were administered…

A study of the acquisition of time-related grammatical forms in Hebrew-speaking children looked at three kinds of information: (1) relative frequency of occurrence of different verb forms at different ages; (2) the relationship between tense-marking on verbs and the semantics of verbs used at different ages, and (3) the use of time adverbs…

Reports on preliminary attempts to find a set of non-linguistic categories in minimally verbal infants. A methodology suitable for the presentation of semantically-defined concepts (agent and recipient) was developed. (Author/ED)

A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

Semantic and syntactical features of storybooks in the Southwest Regional Laboratory (SWRL) Reading Program are reviewed and analyzed. To make the scripts match children's oral language as closely as possible within other program constraints and to avoid potential semantic difficulties, the following changes are recommended: (1) the introduction…

A study by Brown and Fraser (1963) shows that children tend to use telegraphic speech, employing content and omitting function words. This limitation involves the grammatical or semantic complexity of the sentences. Braine (1963) attempted to formulate productive rules for the initial stages in the acquisition of syntax by identifying two classes…

When sound takes on meaning for the first time in the life of a child, a giant and prototypic step in the development of his symbolic capacities has taken place. This step is worthy of careful scientific scrutiny. This paper seeks first to describe the steps by which the author's child discovered the existence of meaning in sound, and second, to…
