Although cross-linguistic influence at the level of morphosyntax is one of the most intensively studied topics in child bilingualism, the circumstances under which it occurs remain unclear. In this meta-analysis, we measured the effect size of cross-linguistic influence and systematically assessed its predictors in 750 simultaneous and early…

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…

This review article presents evidence for the claim that frequency effects are pervasive in children's first language acquisition, and hence constitute a phenomenon that any successful account must explain. The article is organized around four key domains of research: children's acquisition of single words, inflectional morphology, simple…

Argues that current attempts to show that forward directionality effects can also be induced in Japanese acquisition do not succeed in supporting the forward directionality preference of anaphora. (57 references) (Author/CB)

Demonstrates the important need for language researchers to fill in the considerable theory data gap regarding the primary acquisition of Spanish by pointing out that theory development could be distorted if cross-linguistic comparisons of acquisition evidence draw on a faulty, incomplete data base. (CB)

Examines the Child Language Data Exchange System (CHILDES), its organizational form, and its three major tools: (1) the CHILDES database of transcripts, (2) the CHAT system for transcribing and coding data, and (3) the CLAN programs for analyzing CHAT files. (GLR)

Argues that the measures of content and style of maternal talk used by the Murray and Trevarthen (1986) study of temporal patterning during vocal engagements did not directly indicate the ways in which the behaviors of the partners (mothers and infants) were combined on a moment-to-moment basis. (Author/CB)

Argues against Youssef's treatise which pointed out some difficulties in attempting to test Bickerton's language bioprogram hypothesis (LBH), contending that the treatise seriously misunderstood certain key concepts of the LBH and dismissed with questionable reasoning some important findings which supported the state/process distinction as a…

Considers the culturally patterned set of analogic renamings found in Huli baby talk, nursery rhymes, and children's verbal games. An analysis of socialization activities shows a marked concern with body motifs and appellations and inter-adult behavior involving talk about the body, and showing that such language sensitizes children to cultural…

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

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…

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)

Research on child language acquisition should distinguish between different possible causes of variation and not just attribute variation to individual variation. An alternative analysis using a different methodology can show that children's patterns of acquisition are actually relatively similar. (Author/CB)

Re-examines research literature supporting the idea that infants and young children simultaneously learning two languages mix elements from the two languages. It is argued that, contrary to most extant interpretations, bilingual children develop differentiated language systems from the beginning and are able to use their developing languages in…
