I review the classic literature in generative grammar and Marr's three-level program for cognitive science to defend the Evaluation Metric as a psychological theory of language learning. Focusing on well-established facts of language variation, change, and use, I argue that optimal statistical principles embodied in Bayesian inference models are…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

This paper reports progress in developing a computer model of language acquisition in the form of (1) a generative grammar that is (2) algorithmically learnable from realistic corpus data, (3) viable in its large-scale quantitative performance and (4) psychologically real. First, we describe new algorithmic methods for unsupervised learning of…

This paper reports on a study conducted to determine the abilities of children to make optional transformations in sentences conjoined with "and." The subjects were 35 middle-class children between the ages of five and eight, who demonstrated average school achievement, spoke standard American English, and had normal speech and hearing. A…

The basic-operations hypothesis predicts that for any transformation which is composed of more than one basic operation, there exists a class of errors in children's speech correctly analyzed as failure to apply one (or more) of the operations specified in the adult formulation of the rule.

Samples of written language were collected from 140 congenitally deaf children at grade levels 3, 5, 7, and 9. The samples were then subjected to error, quantitative, and transformational analysis. Findings suggested a relationship between the order in which the deaf child acquires the rules of his language and the ordering of rules in a…

This project seeking to develop sound methodological research techniques for second-language is based on an initial pilot study which (1) identified and classifies the utterances of a child learning Spanish as a second language, and (2) determines whether there are any significant trends in the observed order of learning of kernels and transformed…

In the current debate about the development of language in children, the author agrees with those psycholinguists who emphasize the role of "imitation followed by analogical extension." That is to say, that if there are inborn discovery procedures for the acquisition of language, they are distributional rather than transformational in nature. On…

Two claims about early stages of language development--that of a limitation on length of utterance and that of reduction rules which delete major constituents from simple sentences--are questioned. Supporting arguments are reviewed, and alternative explanations offered. (RM)

A report on a study in progress of the acquisition of a syntax rule: inversion in questions beginning with "Wh..". Its purpose is to show how certain modifications of linguistic theory and practice can contribute to this study and to psychology of language in general. (Text is in French.) (AMH)

THE AUTHOR FEELS THAT TO APPROACH CHILD LANGUAGE TRANSFORMATIONALLY IS TO USE A TECHNIQUE SUITED TO PROVIDING ADDITIONAL INSIGHT INTO A WELL-KNOWN LANGUAGE FOR TREATING AN UNKNOWN, OR AT BEST LITTLE KNOWN LANGUAGE. SHE MAKES THE FOLLOWING CRITICISMS OF TRANSFORMATIONAL ANALYSIS OF CHILD LANGUAGE--(1) NOTHING CAN BE DIRECTLY INFERRED WITH REGARD TO…

Children's language acquisition is viewed by developmental psycholinguists as a process of change in the organization of language processing operations. Normal children seem to acquire their native language by this process, rather than by eliminating specific mistakes. Preschool language develops in stages, and knowledge of where syntactic change…

The relationships between a child's perceptual space and the acquisition of language are discussed in light of the work of Clark, Fillmore, and Chafe. Early language is analyzed as a semantic structure where linguistic ties are established between semantic features and inherent and relational perceptual features. Of these, it is the relational…

This article clarifies the position taken in the Greenfield and Smith book (1976), including relation to speech act theory, and elucidates some general theoretical issues in early language development. (Author/NCR)
