This meta-analysis examined associations between the quantity and quality of parental linguistic input and children's language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of…

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…

Traditionally, acquisition of syntactic knowledge and the development of sentence comprehension behaviors have been treated as separate disciplines. This article reviews a growing body of work on the development of incremental sentence comprehension mechanisms and discusses how a better understanding of the developing parser can shed light on two…

Presents a study of young children's understanding that pronouns and proper names cannot be modified by pronominal adjectives. Some nonsyntactic theories are discussed that support the claim that children understand knowledge of word order through the rules that order abstract linguistic categories. (31 references) (GLR)

Presents examples of how children acquire language through the principles-and-parameters model, a highly modular system in which different theories interact so that only permissible sequences arise, and highlights research on Spanish syntax and semantics. (136 references) (CB)

Reviews research on contributions of the child's environment to the development of syntax and semantics. Current theoretical proposals for internal and external constraints are discussed, and the implications of the research for the theoretical descriptions of the child's contribution to development are considered.

A research review of the relationship between children's oral language proficiency and the development of linguistic awareness and learning to read. (CM)

Reviews research concerning language acquisition in infants, particularly the acquisition of syntax. Topics of discussion include the problem of language acquisition, theories of language acquisition, and the progression from competing hypotheses to mutually reinforcing theories. (RJC)

Arguing that the vagueness with which the relationship between social interaction and language is often treated in the literature makes it difficult to explicate and evaluate different views of that relationship, this paper poses four questions designed to differentiate positions and to provide a system for organizing data potentially relevant to…

Argues that the extent of a child's sense of story influences the child's prediction of syntax and comprehension. Suggests ways for teachers to encourage children to develop their sense of story. (RL)

If the basic operations hypothesis (EJ 184 227) is interpreted as a general principle governing acquisition of all movement rules, it may obscure the fact that children distinguish between unbounded and local rules. Error patterns support this distinction, lending credence to theories with separate status for the two rule types. (Author/RD)

Studies on the acquisition of relative clauses are reviewed. Two polarities among a variety of possible approaches are: Slobin's (1971) study that emphasizes acquisition process and learning strategies, and studies like Sheldon's (1974) that emphasize the linguistic structures involved. Early proposals that children experience more difficulty in…

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…

This paper attempts to show the relationship between variable rules and more widely used psycholinguistic constructs such as amalgams and schemas, and to point out how variationists' methods can be useful in the study of language acquisition. The traditional rule, the rule for forming the past tense of regular verbs in English, is discussed as it…

Argues that while many publishers may simplify the sentence structure in the basal reader to facilitate the process of learning to read, this practice may result in texts with stylistic features and text formats that are unnatural and uncharacteristic of written English or the language development level of the children.
