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…

To understand the development of number-word construction, students in grades 1, 3, 5, and 7 named and counted from a set of numbers into the billions in two studies. Findings are discussed both in relation to children's growing knowledge of the number system and to vocabulary development. (Author)

Examination of the speech of eight mothers and eight fathers to their one- to two-year-olds (N=8) indicated that, while paternal speech was not more diverse than maternal speech, paternal speech did show greater use of rare vocabulary and lower use of common vocabulary. (Author/CB)

A longitudinal study of four 17- to 33-month-olds revealed that their linguistic selection at the one-word stage was governed by principles of informativeness, while the two-word stage was characterized by new, or a combination of new and old, information. (Author/CB)

Demonstrates through a case study and a participant observation study that siblings interact about television in such a way that the form and content of their talk creates a learning context. Concludes that, despite concerns about "zombie" viewers, children are not passive, unresponsive recipients of television. (PD)

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)

Examined overregularization of irregular verb forms in children's language learning. Found that overregularization errors are relatively rare; occur at a constant rate; and are not correlated with the proportion of regular verbs in parents' or children's speech. Also found that a period of correct performance precedes the child's first error. (BC)

A 7-month longitudinal study of 20 2- and 3-year-old children shows that children at an early age already know that counting words each refer to a distinct numerosity, although they do not know to which numerosity. It takes children a long time to learn the latter. (SLD)

Discusses pre-linguistic and linguistic stages of language acquisition that are part of a continuum of receptivity and communication every child experiences in the first 3 years of life. Suggests parents assist language development by being sympathetic to each developmental turning point, providing the right emotional climate for expression, and…

Discusses the centers of language in the brain and the critical period for language acquisition. Explains developmental milestones of language development--receptive language, babbling, short phrases, full sentences--in the context of brain development. Emphasizes parents' role in language development, including talking to the child, dialogic…
