The MacArthur-Bates Communicative Development Inventories (CDIs) are a widely used family of parent-report instruments for easy and inexpensive data-gathering about early language acquisition. CDI data have been used to explore a variety of theoretically important topics, but, with few exceptions, researchers have had to rely on data collected in…

Many English-speaking children use plural nominal forms in spontaneous speech before the age of two, and display some understanding of plural inflection in production tasks. However, results from an intermodal preferential study suggested a lack of "comprehension" of nominal plural morphology at 24 months of age (Kouider, Halberda, Wood,…

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…

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age less than 33 weeks and/or birth weight less than 1,500 grams) and a comparison sample of 102 children born full term…

Results suggest that children can use the rules of conversational sequencing to evaluate the need for an inference to the speaker's intent when speakers deliberately violate a rule. This ability is acquired by six or seven years of age, but children do not correctly infer the speaker's intent until they are eight or nine years old. (Author/RH)

Examines the process of language acquisition as well as scientists' understanding of the intricate process of learning to talk. Specifically addresses: (1) foundations of language; (2) prenatal period; (3) first month after birth; and (4) conversation. Also discusses adult-child activities that stimulate language-learning.

This paper examines the referential strategies used by Japanese children and adults in two story telling tasks focusing upon the following discourse contexts: (1) first mentions of story characters, (2) references in subject position to the same character, and (3) references to another character. The subjects, 60 children and 10 adults, were…

Speech samples were elicited by means of the Bilingual Syntax Measure from eleven children ages 27-48 months, covering a wide span of linguistic development. Presence or absence of eleven functors was scored in obligatory occasions and an acquisition sequence determined using three methods of speech analysis. (CHK)

Three experiments gauging 7- to 10-year-old children's ability to interpret and comprehend figurative language indicated that informative contexts could improve subjects' abilities to perceive idiomatic meanings. Subjects were less able to produce idioms than to comprehend them, but were able to perceive that language can be both figurative and…

By analyzing different language tests currently in use for elementary school children, the article criticizes psychometric means of evaluation and ideas about language and language acquisition resulting from psychometric evaluation. (Text is in French.) (CLK)

Examines psychologist David R. Olson's current work on children's language development and its possible educational implications. Stresses the increasing tendency to investigate children's language development in relation to their thinking and learning rather than in isolation and to include literacy development in the oral language development…

A study investigated whether imitation plays a significant role in the acquisition of grammar. Three 6- to 8-year-old hearing-impaired children were administered the Grammatical Analysis of Elicited Language--Simple Sentence Level Test (GAEL), which is designed to evaluate hearing-impaired children's use of grammatical aspects of spoken and/or…

The article reports on an experimental study undertaken in a suburban Parisian kindergarten to determine the optimum environment for child language development. Adult-child interaction is underlined as essential in the acquisition process. Observation methods and specific examples of the effect of child-adult interaction are outlined. (Text is in…

For the two children studied and in the situations observed and recorded, important conditions for the emergence of language in the ontogeny of communication appear to be: (1) interaction with caretaking adults, (2) shared focal attention, and (3) specificity of reference. (Author)
