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…

Considers children's understanding and use of contrast in language, including discussion of the role contrast plays in adult speech, the kinds of contrast commonly exemplified, and possible tests for sameness or difference of meaning. (CB)

Reviews recent studies concerning the acquisition of gender systems of different languages and the development of the mass/count distinction in English, focusing on evaluation of the early formal learning approach. (CB)

Reports on four school-age boys' use of the specialized register of sportscasting as performed both spontaneously and when elicited by the researcher, and compares the boys' production of formal register-marking features to adult usage. (27 references) (GLR)

Two experiments indicating that children's linguistic generalizational biases change from a semantically-based system to a syntactical-structural system provide evidence for a semantic-relational bias in children's early grammars and support the notion that children's generalizational biases shift from a semantic-relational basis to a…

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.…
