The paper describes recent research investigating the relationship between speed with which individuals can execute basic cognitive processes and performance on tests of intelligence and mental ability. Results are discussed in terms of three properties of the working-memory system which limit the amount of information for simultaneous storing and…

Experiments with two distinct collections, using three levels of indexing exhaustively for both documents and requests, show that substantially the same performance is obtained for very different levels of document indexing, if suitable choices are made of request level. (6 references) (Author)

Because they look to the computer for automatic processing of verbal information, linguists have allied themselves with mathematicians. (10 references) (Author)

Describes the current status of developments concerning the regulation of information flow across national borders. Similarities and trends in various privacy laws from European countries are discussed, as are the business position on data protection and efforts to harmonize national laws. (SW)

Presents an overview of the impact of fiber optics on telecommunications and its application to information processing and library services, including information retrieval, news services, remote transmission of library services, and library networking. (RAA)

Presents a class of distortion controlled vector quantizers that are capable of compressing images so they comply with certain distortion requirements. Highlights include tree-structured vector quantizers; multiresolution vector quantization; error coding vector quantizer; error coding multiresolution algorithm; and Huffman coding of the quad-tree…

Lesioning studies are often used in cognitive neuroscience to make inferences about the architecture of cognition. Recently, computational models have been used to address some of the underlying assumptions-such as modularity and locality-often implicitly used when interpreting lesion data. In this article, we explore the ''functional…

This article highlights basic issues that have hindered e-learning systems from becoming the revolutionary force it could be for education. While current systems aim to foster significant improvements in learning, this article argues that most systems are still limited to just being online repositories. This and the lack of learning…

This study investigated how 4- to 7-year-old children's second-order belief attribution might be facilitated by either reducing information processing or varying the sequence of task questions. In Experiment 1, compared with Perner and Wimmer's (1985) original second-order false-belief task, a new task with reduced information-processing demands…

Presents the results of an investigation into information structures in natural language science texts. (Author)

The aim of the study reported here was to investigate an alternative method for scoring Flanders' Interaction Analysis Categories when students' competence in coding lesson transcripts was being assessed. (Author)

This discussion of the development and application of lasers and microprocessors to information processing stresses laser communication in relation to capacity, reliability, and cost and the advantages of this technology to real-time information access and information storage. The increased capabilities of microprocessors are reviewed, and a…
