The uniform principle assuming that comprehension precedes production in language acquisition was examined using Down's Syndrome children taught to comprehend singular/plural nouns and produce such forms for another noun. Three subjects reached criterion production first and one reached comprehension first, suggesting the modes can develop…

Longitudinal studies of the application of a paraphrasing model to 18- to 28-month-olds indicated that mean length of utterance was significantly correlated with realized and paraphrased frequencies of several linguistic items in the subjects' corpora. The model was productive for examining children's corpora of speech and the linguistic…

A review of studies of word learning by normal adults and children, neuropsychological patients, and special development populations provides evidence that the phonological loop plays a crucial role in learning the novel phonological forms of new words, suggesting that the phonological loop stores unfamiliar sound patterns while more permanent…

Discusses the interaction of age and sex factors on consistency of recognition of 71 Peabody Picture Vocabulary Test pictures by preschool children. (TO)

The antecedents of verbal behavior, together with the teaching skills of the adult linguistic community, probably constitute all the necessary bases for language acquisition. As they seemed to be sufficient for the explanation of all the known phenomena, an assumption of an innate linguistic language acquisition device was rejected as superfluous.…

Author observed four kindergarten classes where teachers were able to speak Spanish; Spanish-speaking children, by various methods, learned skills and content at the same rate as English-speaking children did. (SP)

Results of two studies with 45 normal three- to five-year-old children indicated that, when the Ss initiated actions with verbal instruction, their use of conjunctions and clause ordering was more effective than in other initiated contexts without a verbal model. (Author/MC)

Thirty 4- and 5-year-olds with specific language impairment (SLI) and 30 normally developing peers participated in a discrimination learning-shift paradigm. Both groups were equally successful in extracting regularities from recurring nonverbal stimuli and in making shifts. Findings failed to provide evidence that children with SLI are less able…

Three experiments investigated whether preschoolers attend to actions or object when learning a novel verb. Findings showed that children learning nouns in the context of novel, moving objects attended exclusively to appearances of objects. Children learning verbs attended equally to appearances and motions. With familiar objects, children…

Uses a quasi-experimental design to compare the social adjustment of 21 children who received the Language for Learning program with those of 24 children enrolled in a comparison school. Finds that the Language for Learning program produced statistically and educationally significant effects, including improvements in social skills and reductions…

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month old infants. Infants' ability to learn either words or symbolic gestures as names for object categories were compared across age groups. Findings indicated that infants at both ages learned novel words as symbols for object…

This study was concerned with the effects of specified dimensions of teacher behavior on the language development of socially disadvantaged preschool children enrolled in Head Start. The hupothesis, later verified by the findings, was that teachers showing high levels of competence in eliciting verbal behavior from their pupils and rewarding them…

Discusses the inadequacies of the linguistic development theory called cognitive determinism and suggests instead the linguistic input hypothesis. Concludes that it is not either cognitive development or linguistic input that determines linguistic growth, but an interaction between them. (RM)

Children at three age levels were administered Schutz and Keislar's word-span task using nouns, verbs and functors as stimuli. (Author/RM)

Investigates whether the asymmetry in children's acquisition of polar adjective pairs is based on linguistic factors related to differences in adult usage and frequency or on an underlying conceptual difference. Results suggest acquisition is based on an underlying conceptual asymmetry. (DP)
