The semantic memory search process was examined in second graders (N=30) under an induced imagery and a control condition. (MP)

The storage and retrieval of individual sentences occuring in small sets was substantially enhanced when the sentences were nominally linked by common concepts and when the learner was encouraged to process them semantically. Sentence recall was also positively increased when the learner perceived them to be in a meaningful order. (RC)

Presents evidence that although patients with semantic deficits can sometimes show good performance on tests or object decisions, this pattern applies when nonsee-objects do not respect the regularities of the domain. Patients with semantic dementia viewed line drawings of a real and chimeric animals side-by-side and were asked to decide which was…

This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

Word substitution errors from a corpus of 2,400 French slips of the tongue were grouped into several categories: contaminational, semantic, formal, and mixed cases; substitutions of syntagmatic codependents also occurred. Semantic and formal substitutions involved a resemblance between target and error. All substitutions exhibited a strong degree…

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)…

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)

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.…

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)

The study investigated gender differences in resting EEG (in three individually determined narrow [alpha] frequency bands) related to the level of general and emotional intelligence. Brain activity of males decreased with the level of general intelligence, whereas an opposite pattern of brain activity was observed in females. This difference was…

We present statistical analyses of the large-scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small-world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of…
