Background: Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school-age outcomes of late-talking toddlers. Methods: In a five-wave follow-up…

Examines the understanding of the pragmatic function of mental terms ("think,""know,""guess") to express the relative certainty of 69 children aged 3-11. Results showed an improvement with age for the "know-think" and "know-guess" contrasts, but no improvement with age for the…

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:…

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…

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…

This paper discusses C. Chomsky's 1969 paper on children's syntactic development and the subsequent studies made to test her findings. Later studies indicate that Chomsky's results were not clearly differentiated, and a slight alteration in procedure changes results significantly. (CHK)

Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Speculative explanation for the misapplication of adjectives for adverbs in colloquial speech, e.g., He drives good'' for He drives well.'' (RS)

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

This case study of two Latvian children attempts to show how the parental terms for"mummy" and "daddy" in Latvian are acquired, paying particular attention to the changing relationship between the input and output forms during the acquisition process. (Author/RM)

A study of the utterances of young children, aged 7 to 22 months, is described. These utterances, varying in length from one to 17 syllables, contain only suprasegmental information because the verbal content was incomprehensible to hearers who were not acquainted with the child and the situation in which the utterances occured. In the corpus,…

The hypothesis explains the early lexical development of children and the predictions of this hypothesis are shown to be consistent with available data on overextension. (Author/NCR)

Extensive longitudinal data were gathered on a child's entry into the symbolically mediated modal world by examining changes in the semantics and pragmatics of her uses of modal auxiliary verbs. The data are 53 transcripts of natural conversations between a girl, Nina, and her mother recorded periodically from her 23rd month to her 39th month. The…

Two investigations of the acquisition of the meaning of "always" and "never," and "always,""never,""usually,""seldom," and "sometimes" are discussed. Results demonstrate that the acquisition sequence of meanings of related words may vary among children at the beginning, but become consistent in later acquisition. (CHK)

This chapter, to be included in "Carmichael's Manual of Child Psychology," edited by P.A. Mussen, deals with the connection between the acquisition of language and the growth of intellect, and the connection between both of these and the process of maturation. The author feels that various theories of development cannot account for the child's…
