Research Findings: Early childhood teachers' talk is a key ingredient in children's early language and literacy development, but there has been little systematic synthesis of observational studies that examine relationships between teacher talk and child oral language. In this systematic review of 54 studies, we investigate and synthesize the…

Language exerts a powerful influence on our concepts. We review evidence documenting the developmental origins of a precocious link between language and object categories in very young infants. This collection of studies documents a cascading process in which early links between language and cognition provide the foundation for later, more precise…

Reviews evidence supporting the Contrastive Hypothesis, revealing little support for the hypothesis that young children automatically assume that every two words in their lexicons contrast. Theoretical problems with the positions that children assign words to semantic fields as they are acquiring them and that innovations are used to fill lexical…

Applies a categorical framework for relating compounds and metaphors to a discussion of the aspects of children's development of preferred and metaphoric compounds. Results indicate that preferred compounds serve the function of being conceptually precise, while preferred metaphors serve "suggestive" functions. (Author/CB)

Presents a method and rationale for enhancing verbal learning in a typical reading-language arts lesson through personal and group generated images and associations. (FL)

Reviews current research on children's concepts and categories that reflects a growing consensus that nonperceptual knowledge is central to concepts and determines category membership, whereas perceptual knowledge is peripheral in concepts and only a rough guide to category membership. Argues that there is no compelling basis in theory or in data…

To offer a historical perspective on vocabulary studies, this paper presents summaries, reviews, and critiques of vocabulary studies in chronological order of publication. The only variance from this format are published rebuttals and/or critiques, which are presented immediately following the original studies. The paper is divided into two parts.…

Type/Token Ratios (TTRs) frequently fail to discriminate between children at widely different stages of language development, and may fall as children get older. Such effects are caused by a negative, though non-linear, relationship between sample size and TTR. Standardization of the number of tokens before computing TTRs is recommended.…

Concludes that it is time for teachers to be more critical of the commercial materials and classroom practices commonly used to sensitize children to different semantic cues and morphological units. Argues that without a firm knowledge of context clues and morphemes on the part of teachers, the teaching of these skills will remain incidental. (FL)

Presents evidence revealing the complexity of young children's language understandings with regard to spelling patterns, parts of speech, and vocabulary; points out that teachers must build upon the language knowledge that children bring to school. (GT)

The past 20 years have seen research on language acquisition in the cognitive sciences grow immensely. The current paper offers a fairly extensive review of this literature, arguing that new cognitive theories and empirical data are perfectly consistent with core predictions a behavior analytic approach makes about language development. The review…
