Observation of adult response to children's initial overextensions (use of the correct label, correction of error, and demonstration of object attributes) revealed that demonstrations were the most important factor in inducing toddlers to assign an object to its adult category. (Author/CB)

Analysis of longitudinal data from four Mexican-American children to explore two aspects of the acquisition of Spanish word stress indicates that children approach such learning unbiased toward any particular stress type. Children's attention to phonetic or semantic aspects of normatively unstressed syllables leads them to shift stress to that…

Relationships between syntactic and semantic aspects of mothers' speech and infants' word acquisition was examined in 27 mother-infant dyads. Results indicated that the more the mother differentiated the complexity of her speech to child and adult, the earlier the child attained 20 words. The more the mother used adult-basic labels in her speech,…

Presents a brief report of a study along with an extensive criticism of this and other studies that use contrived tasks for investigating children's humor and writing. (FL)

Examines speech samples from six children aged 2 years to 2 years, 5 months, with Mean Lengths of Utterance ranging from 2.93 to 4.14, were examined for evidence of six syntactic categories: determiner, adjective, noun, noun phrase, preposition, and prepositional phrase. (HOD)

Reports on two studies that examined the natural process of word learning in children 4-11 years old. The children hear the new words in a conversation, a story, and paired with a definition. Results indicate that children at all ages could acquire a partial semantic representation from a single exposure. (SED)

Twelve preschool nonstutterers and their mothers were matched with 12 stutterers and their mothers. Analysis of intervention demonstrated that mothers of stutterers talked significantly faster to all children. Stutterers spoke slower than nonstutterers and severe stutterers spoke slower than moderate stutterers. Results revealed an interactive and…

Describes the formation of the Child Language Data Exchange System (CHILDES), a system formed to foster the sharing of computerized data on language acquisition. Details the governance of the system, the nature of the database, the shape of the coding conventions, and the types of computer programs being developed. (SED)

Describes a study which examined the relationship between mother's speech and the rate of child syntax growth for 22 two-and-a-half-year-old children. Results suggest that linguistic experience does contribute to syntax development but that the relation between linguistic input and language growth is different for different domains of language and…

Describes a study designed to compare color-name with shape-name learning by three-year-old children in an experimentally controlled format. Results show that children learned color-label associates significantly more slowly than matched shape-label associates, and they committed more errors with colors than with shapes during learning. Provides a…

Uses both the findings of formal research studies and the observations of sensitive teachers to illustrate the power of language for helping children gain control over, and put their mark upon, their surroundings. (HTH)

Describes an experiment which tested the infant's sensitivity to the timing of the mother's responses by arranging a video system so that mother and baby each saw a full-face, life-size image of the other on a video screen. Results provide evidence for the infant's active role in interaction with adults. (SED)

A cross-sectional and a longitudinal study of two-year-old children was performed to investigate the developmental relationship between understanding differences in spatial point of view and correct comprehension and production of I/you pronouns. Results suggest that understanding spatial points of view is a cognitive prerequisite to understanding…

Discusses results of study that attempted to determine whether subject-auxiliary inversion occurs in yes-no questions before wh-questions and whether noninversion errors are characteristic feature of acquisition of wh-questions. Findings do not support previous claims that inversion is acquired in yes-no questions before wh-questions. Rather,…

Discusses the audio and video-recorded longitudinal data from six infants with varying degrees of vision. The findings indicate that there are basic differences in early language, which appear to reflect differences in cognitive development. (SL)
