Describes a computational model of high-dimensional context space: the Hyperspace Analog to Language (HAL). Shows that HAL provides sufficient information to make semantic, grammatical, and abstract distinctions. Demonstrates the cognitive compatibility of the representations with human processing; and introduces a new methodology that extracts…

Offers an introduction to the theory and implementation of Latent Semantic Analysis (LSA), a theory and method for extracting and representing the contextual-usage meaning of words by statistical computations applied to a large corpus of text. Gives an overview of applications and modeling of human knowledge to which LSA has been applied. (SR)

Comments on several quantitative approaches to semantic knowledge representations (the focus of this special issue). Points out some of the ways in which Latent Semantic Analysis and Hyperspace Analog to Language fall short of being plausible theories about psychological reality. Examines in-principle failures and wrong-kind failures that arise in…

Tests earlier claims about the universality of patterns of polysemy and semantic extension in the domain of perception verbs. Utilizing data from a broad range of Australian languages, two hypothesized universals are addressed: Viberg's (1994) proposed unidirectional pattern of extension from higher to lower sensory modalities and Sweeter's (1990)…

A professor recounts how he communicates his philosophy of education and establishes an interactive classroom atmosphere during a class's first meeting by using a questioning, game-like discussion of the meanings of such terms as "education,""student," and "teacher." (DB)

Carried out simulations in which a set of morphologically-related words varying in semantic transparency were embedded in either a morphologically rich language (Hebrew) or an impoverished artificial language. Found that morphological priming increased with degree of semantic transparency in both languages. (Author/VWL)

Knowledge of derivational suffix meanings was investigated in 10 subjects (ages 10-12) with language learning disabilities and typical peers. Students produced derived forms from nonce bases in an elicitation task and selected derived forms in a forced choice task. Elicitation task accuracy of subjects fell substantially below that of peers.…

Measures the impact of cross-cultural differences on language learners' interpretation of imageable idioms--idioms that have associated conventional images. French-speaking students were asked to guess the meaning of unfamiliar English idioms without contextual clues. Results invite teachers and learners to approach the semantics of imageable…

Presents the case for a mapping theory of developmental language impairment, which branches into a theory that specific language impairment arises from impaired phonological processing and the consequent disruption of the mapping process through which the words and sentence structure of language are established. (Author/VWL)

Discusses the basic elements of a global cognitive theory for information retrieval (IR) interaction from a cognitive point of view. Within this framework are outlined the principles underlying the concept of polyrepresentation applied simultaneously to the user's cognitive space and the information space of IR systems. Contains 95 references.…

Four studies examined the influence of essentialist information such as internal properties and perceptual similarity on 3-, 4-, and 5-year olds' interpretations of labels. Results suggested that children have essentialist beliefs about animals, but not about artifacts, and that these beliefs interact with children's assumptions about word meaning…

Some research has posited a natural order of acquisition of English grammatical morphemes common to all learners of English as a Second Language. This meta-analysis investigated whether a combination of five determinants--perceptual salience, semantic complexity, morphophonological regularity, syntactic category, and frequency) accounts for a…

Examined whether phonological information was activated automatically in processing two kanji compound words. In one experiment, participants judged whether pairs of words were homophones, while others judged whether pairs were synonyms. In the second, participants were asked to make one of the two judgments, as in experiment one. Findings support…

Notes young children's fast mapping ability for word and fact learning. Finds children's extension of a new word to novel objects from same category but lack of extension for new facts, as replicated by Waxman and Booth, unsurprising. Poses more interesting question: is word learning done solely through more general cognitive systems or through…

Exploits the diachronic potential of vantage theory with psychologists' notion of framing. Compares vantage theory and cognitive grammar, based on the analysis of a particular problem in the history of French, the development of the negator "pas" (not) from a full noun. (Author/VWL)
