Examined effects of direct intervention on language learning. Using a toy manipulation task, 18 children aged 3;6 to 4;6 were systematically taught linguistic structures beyond their developmental grasp. Solid improvement was found in the experimental conditions; no significant improvement was noted in control conditions, showing that the language…

In a study using preschool and elementary school children, the children's judgments of whether brief stories described valid instances of a concept shifted in a manner consistent with the authors' hypothesis that meanings typically develop from representations in which characteristic features predominate to those in which defining features become…

Investigates in an experimental setting the claim that young children have some knowledge of the rules of correspondence between language and reality which are central to propositional logic. (EKN)

Reviews recent research, and discusses difficulties inherent in research, on the language development of bilingual children. Recommendations are made supporting a multidisciplinary approach to research on language development in bilingual children, and suggested avenues of inquiry within such a framework are outlined.

Assesses three papers in this volume, those by Wellman and Estes, Olson and Torrance, and Hall and Nagy, for their treatment of the following: (1) definition of semantic space, (2) defining children's processes of understanding that space, and (3) describing the contexts in which cognitive language is used. (AEW)

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,…

Examines the development of children's knowledge about the presuppositions of cognitive verbs that take sentential complements. Results indicate that the presuppositions of the factives "know,""forget," and "remember" and the nonfactive "think" are not learned until age four. "Believe," which has factive and nonfactive properties, is mastered…

Young children found it difficult to verify negative statements, but found affirmative statements, affirmative questions, and negative questions equally easy to deal with. It is proposed that children acquire the answering system earlier than the verification system, and use answering to verify statements before acquiring the verification system.…

Major findings are reported of a longitudinal, naturalistic study of grammatical morpheme development in an aphasic child from 5;5 to 6;1. The majority of the morphemes were not acquired in the same order nor at the same mean length of utterance (MLU) levels reported for normal children. As an alternative to the normal acquisition model, based on…

Describes an experiment to see whether the words "front" and "back" introduce the concept of "front-back" or whether the concept preceded the words. Results show that (1) a complex disjunctive concept of "front-back" orientation precedes any knowledge of the words; (2) linguistically, "back" is comprehended before "front"; and (3) children at an…

Describes a study in which children are asked to choose the most probable or permissible of two modal propositions, a technique which assesses the children's appreciation of relative force. Results indicate that the general acquisition rule was: the greater the difference in the strength of the two modal propositions, the earlier the difference…

Forty-five children drawn equally from nursery school, kindergarten, and first grade were administered a nonverbal imitation task, a production task, a comprehension task, and a verbal imitation task. The results of the four tasks support the Temporal Complexity Hypothesis, which states that the components of temporality--order among events (O),…

Narrative observations were made of remedial interchanges occurring among school children (K-4) in open classrooms. Transcripts of interchanges were typed move by move and coded according to a hierarchical coding scheme (remedy, defiance, no response, relief, ending, and ambiguous). The interchanges of the kindergarteners and first graders were…

Addresses two questions: (1) When do children who are bilingual from birth become aware that they speak two languages? and (2) What are the factors that lead to this awareness? The subjects in the study described here were Italian/German bilingual children living in the Italian region of Alto Adige. (CFM)
