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…

The ability to generate novel utterances compositionally using generative knowledge is a hallmark property of human language. At the same time, languages contain non-compositional or idiosyncratic items, such as irregular verbs, idioms, etc. This dissertation asks how and why language achieves a balance between these two systems--generative and…

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…

We study the learnability problem concerning the dative alternations in English (Baker, 1979; Pinker, 1989). We consider how first language learners productively apply the double-object and to-dative constructions ("give the book to library"/"give the library the book"), while excluding negative exceptions ("donate the…

Among known communication systems, human language alone exhibits open-ended productivity of meaning. Interest in the psychological mechanisms supporting this ability, and their evolutionary origins, has resurged following the suggestion that the only uniquely human ability underlying language is a mechanism of recursion. This "Unique…

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…

In an attempt to explain first language attrition in emigrant populations, this paper investigates the explanatory power of a framework that has--until now--received little attention: the regression hypothesis (Jakobson, 1941). This hypothesis predicts that the order of attrition is the reverse of the order of acquisition. The regression…

An analysis of the speech of infants gives a clue to the evolution of language. (DR)

We introduce a computational theory of situated language understanding in which the meaning of words and utterances depends on the physical environment and the goals and plans of communication partners. According to the theory, concepts that ground linguistic meaning are neither internal nor external to language users, but instead span the…

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. (Author/CTM)

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…

Research (1968-1978) on the development of generative grammar in mentally retarded students is summarized for such topics as noun pluralization and suffixes, pronouns, adjectives, articles, verbs, prepositions, interrogatives, and generalization. Unresolved issues in generalization are noted. (CL)

Investigates the differences in syntactical structure of sentences written by school children of different ages and of different abilities within the same grade. Writing of certain adults is also studied. (MH)

Two experiments involving four and seven normal children four- to eight-years-old examined processes responsible for generative language acquisition and conditions likely to facilitate recombinative generalization. All children learned new syntactic rules to generate three word utterances, regardless of the orderings of agent, action, and object…
