Using a meta-analytic approach, we evaluate the association between socioeconomic status (SES) and children's experiences measured with the Language Environment Analysis (LENA) system. Our final analysis included 22 independent samples, representing data from 1583 children. A model controlling for LENA[TM] measures, age and publication type…

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)

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.…
