Mothers were found to respond differentially to their infants' object-related gestures. Pointing was found to have an especially strong correlation with mothers' object-labelling responses, which in turn were predictive of the child's object-naming vocabulary. (Author/JB)

Three experiments introduced 2- and 3-year-olds to novel adjectives either using full noun phrases and describing multiple familiar objects sharing a salient property or describing nouns of vague reference. Found that both groups mapped novel adjectives onto object properties when given taxonomically specific nouns with rich referential and…

A study of two- to six-year-olds' spontaneous uses of "from" to mark oblique agents showed that, while the two-year-olds produced "from" for agents and "with" for instruments in imitation, older subjects shifted to "by" for agents and kept "from" to mark locative sources. (Author/CB)

This study reports data on form classes (e.g., nouns, verbs, modifiers) of the early vocabulary of an English-speaking boy with autism, to determine whether his language acquisition was referential or expressive. Results are compared with norms for normal and Down's syndrome populations. The predominance of nominals suggests a referential language…

Students, ages 12, 15, 18, and 23 (n=60 per group), wrote definitions for 16 abstract nouns. Responses were analyzed for Aristotelian style. There was an increasing tendency for students to mention the appropriate category to which a word belongs, core features of the word, and subtle aspects of meaning. (DB)

The composition of young children's vocabularies in 7 contrasting linguistic communities was investigated. Mothers of 269 twenty-month-olds in Argentina, Belgium, France, Israel, Italy, the Republic of Korea, and the United States completed comparable vocabulary checklists for their children. In each language and vocabulary size grouping (except…

Lidz, Waxman, and Freedman [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Evidence for syntactic structure at 18-months. "Cognition," 89, B65-B73.] argue that acquisition of the syntactic and semantic properties of anaphoric one in English relies on innate knowledge within the learner.…

Assuming the relevance of the linear precedence to the scope interpretation of adult Mandarin, this study investigated the development of this principle in Mandarin-speaking children, with a view to providing a basis for further study of parametric variation. Three kinds of sentences were examined, all of which contained mutually commanding…

In a study of very young children's pronunciation of nouns and verbs, ten children aged 20 to 25 months were exposed to experimental nouns and verbs, which had not yet been comprehended or produced by the children. Each of the objects and actions was given an experimental name based on phonemes in the children's speech. These objects and actions…

Research studies have demonstrated that children tend to define nouns by describing first their function and later the object to which they refer. In a study devised to trace the development of noun definition in the language of grade school children and adults, 20 subjects from each of four grade levels (kindergarten and grades two, four, and…

Scientific Russian vocabulary, as represented by substantives among the lead entries of a 1955 polytechnic Russian dictionary, is analyzed compositionally and by source language. (GK)

Uncertainty scores of the type proposed in this study, if suitably refined, may measure the developmental progression from stereotyped reliance on individual syntactic forms to flexible utilization of productive rules. (Authors/CB)

Reports on experiments examining the semantic organization of concrete nouns and verbs and its development in childhood. Differences in semantic organization are said to be a clue to age-related changes in performance with verbs. (AM)
