Word learning depends critically on the use of linguistic context to constrain the likely meanings of words. However, the mechanisms by which children infer word meaning from linguistic context are still poorly understood. In this study, we asked whether adults (n = 58) and 2- to 6-year-old children (n = 180) use discourse coherence relations…

Paradigmatic literacy features refer to ways of thinking and using language associated with academic-scientific discourse or written language. They are intimately bound up with education and appear in their emergent forms, mainly in conversations with adult partners. The present qualitative study investigates whether, and in which ways,…

The present dissertation extracted 17,291 questions from Aki, Ryo, and Tai and their mother's spontaneously produced speech data available in the CHILDES database (MacWhinney, 2000; Oshima-Takane & MacWhinney, 1998). The children's age ranged from 1;3 to 3;0. Their questions were coded for (1) yes/no questions that include a sentence-final…

This dissertation studies how people describe emotions with language and how computers can simulate this descriptive behavior. Although many non-human animals can express their current emotions as social signals, only humans can communicate about emotions symbolically. This symbolic communication of emotion allows us to talk about emotions that we…

Recent developments in theories of language (grammars) seem to share a number of tenets which mark a drastic shift from traditional disentangled descriptions of language: emphasis on a big number of discrete grammatical rules or a corpus of structure patterns has given way to a more unitary, explanatory powerful description of language informed by…

The ability to explain the occurrence of errors in children's speech is an essential component of successful theories of language acquisition. The present study tested some generativist and constructivist predictions about error on the questions produced by ten English-learning children between 2 and 5 years of age. The analyses demonstrated that,…

Using a discourse analytic approach from the work of Hoey (1991) and a dual processing model from Wray (2000), this paper compares the language produced by the same classes of children when they are engaged in role-play and when they are playing rule-based games. We find that role-play tends to be richer in "frozen" pair parts, where the responses…

Halliday's view of all learning as a form of language development is supported as a first step, but an argument is made for a view of learning as induction into discourses as ways of being, not just ways of using words. (Contains 19 references.) (LB)

An explanatory linguistic theory attempts to capture and explain the universal nature of human language, to choose among possible grammars of each human language, and to account for the linguistic constraints involved in language acquisition. Discourse theory, like linguistic theory, must be mentalistic in that it seeks to account for mental…

The work of two theorists are compared by focusing on a limited number of central issues for a language-based theory of learning (LTL), including long-term goals and a genetic approach; language and social activity; appropriating culture; thinking in school; sociosemantic variation; enculturation; and intellectual consequences. The combined…

A study analyzed three episodes of self-repetition in a 1-year-old's utterances and examined the child's use of self-repetition for exploiting and elaborating on his phonological system in the context of discourse. The subject was a first-born monolingual child in the Stanford Child Phonology project. The analysis provides clues about how the…

The relationship between teachers' theories of language and learning and the nature of classroom discourse is explored. Data from two classes on Aborigine lifestyles suggest that there are three components functioning in all lessons: interpersonal, content, and metalanguage. The quality of the metalanguage component influences the overall quality…

A study analyzed the distribution of words in a three-million-word corpus of text from the "Wall Street Journal," in order to test a theory of the acquisition of word categories. The theory, an alternative to the semantic bootstrapping hypothesis, proposes that the child exploits multiple sources of cues (distributional, semantic, or…

Examines recent attempts to explain children's word use and selection through recourse to information theory. It is concluded that information theory cannot account for the complexities involved in early word selection. (AM)

Sound-meaning correspondences produced by an infant were studied under conditions of early rampant homonymy (i.e., production by a very young child of a small set of noncontrastive surface forms or phonetic sequences to refer to objects/events that on the basis of adult standards require the production of numerous contrasting surface forms). The…
