In this response to commentators, I agree with those who suggested that the distinction between exemplar- and abstraction-based accounts is something of a false dichotomy and therefore move to an abstractions-made-of-exemplars account under which (a) we store all the exemplars that we hear (subject to attention, decay, interference, etc.) but (b)…

Prior research has shown that vocabulary instruction can enhance the comprehension of passages when instruction includes definitional and contextual information, provides multiple instructional encounters with the words, and requires learners to engage actively in processing of word meanings (M. F. Graves, 1986; S. A. Stahl & M. M. Fairbanks,…

This paper discusses the biological and social views of grammar with reference to recent research on grammar and language acquisition, arguing that grammars are individual constructs existing in the minds of individual speakers. Contains 24 references. (MDM)

The nature of the task of defining words by means of other words and the development of language responses (from children aged four to seven) are discussed in terms of a linguistic analysis of the definitional form and its semantic relations. (Author/RM)

Results of three investigations of the development of word definitions indicated that younger childrens' definitions, including use or lack of use of superordinate categorical terms, fell short of adult informativeness, while, by age 10, children generally met such criteria in their definitions. (Author/CB)

The relation definition theory proposed in this paper is explicitly different from previous semantic memory theories since it is the first to make a relation's definition the basis of semantic processing. The paper suggests that this relation definition theory successfully predicts relation similarity on the basis of one key primary assumption:…

Discusses the question of whether nonhuman species, such as apes, possess rudimentary language, focusing on the ideas of Ludwig Wittgenstein and Noam Chomsky in regard to the development of oral language in young children and apes. (51 references) (MDM)

Research studies have demonstrated that children tend to define nouns by describing first their function and later the object to which they refer. In a study devised to trace the development of noun definition in the language of grade school children and adults, 20 subjects from each of four grade levels (kindergarten and grades two, four, and…

Describes two studies of word meaning acquisition among children. Concludes that (1) even very young children can learn new words and their meanings on basis of linguistic expressions and in absence of direct experience with referents, and (2) that particular forms of discourse (e.g., narrative and dialogue) can render new meanings more accessible…

An obstacle in Natural Language understanding is the existence of lexical gaps, i.e. words or word senses that are not in the lexicon of the system. This thesis describes the implementation of MURRAY, a learning mechanism which infers the properties of a new lexical item from its syntactical environment and infers its meaning based on context and…

As part of a wider study of metalinguistic skills, a study examined the metalinguistic awareness of the concept "word" of adults at different literacy levels. Subjects, 60 adult monolingual English speakers enrolled in adult education classes, were divided into three groups according to reading level. Data were gathered through a…

After a pilot study identified possible responses that children and adolescents give when defining concrete and abstract nouns, a study investigated the development of concrete noun (specific objects) and abstract noun (concepts) definitions given by 10, 14, and 18-year-olds, as well as whether abstract and concrete nouns are defined in a parallel…

A study focused on the nature and effect of constraints on the hypotheses that learners make about the meanings of words. Two experiments were conducted at a large midwestern university: the first, involving 68 undergraduate students divided randomly into two groups, tested taxonomic and durative constraints on nouns, and time of day and cessation…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 33 titles deal with a variety of topics, including the following: (1) aphesis in English; (2) the linguistic representation of tone; (3) discourse structure and anaphora in written and conversational English; (4) a tagmemic…

A set of procedures for coding internal state words (those words representing mental states and perceptual experiences), developed for application to data on the language of young children and those with whom they converse, is described in this report. The report first discusses the rationale for studying cultural variation in vocabulary use, the…
