Briefly describes the ERIC system and discusses the costs, who can use it, and what kinds of information it provides. (JOW)

The author presents a seven-point approach to teaching information processing students how to document a system. The method focuses on requiring clear documentation for class projects and scheduling separate due dates for each document required in proper sequence. (CH)

Proposes a new rule system and notation that supports the characterization of a document based on its structure or architecture (primarily linear, paper-copy media). Examples of the application of the notation are provided. (Author/JKP)

Analyzes the computational complexity of optimal binary tree pruning for tree-structured vector quantization. Topics discussed include the combinatorial nature of the optimization problem; the complexity of optimal tree pruning; and finding a minimal size pruned tree. (11 references) (LRW)

Two experiments were performed to assess age-related changes in sequential effects on choice reaction time (RT). Sequential effects portray the influence of previous trials on the RT to the current stimulus. In Experiment 1, three age groups (7-9, 10-12, and 18-25 years) performed a spatially compatible choice task, with response-to-stimulus…

The purpose of the present study aims to investigate the relationship between circadian typology and learning-thinking styles conceptualised as a preference toward information processing typical of the right vs. the left cerebral hemisphere. A sample of 1254 undergraduates (380 boys and 874 girls; mean age=21.86+/-2.37,) was administered the…

Roundhouse is a visually creative information-processing tool (J. E. Trowbridge and J. H. Wandersee 1998). The procedure requires learners to construct knowledge using "mindful" connections to replace less effective practices of memorizing fragmented information. Students create observable organization schemes of related ideas and icons in a…

An electronic portfolio system, designed to serve as a resource-based learning space, was tested in a fifth-grade science class. The control-group students accessed a traditional folder-based information display in the system and the experimental-group students accessed a concept map-based information display to review a science portfolio. The…

Fifteen years ago, Pascual-Leone and colleagues used transcranial magnetic stimulation (TMS) to investigate speech production in pre-surgical epilepsy patients and in doing so, introduced a novel tool into language research. TMS can be used to non-invasively stimulate a specific cortical region and transiently disrupt information processing. These…

A study investigated whether selective attention to a particular television modality resulted in different levels of attention to and memory for each modality. Two independent variables manipulated selective attention. These were the semantic channel (audio or video) and viewers' instructed focus (audio or video). These variables were fully…

The main purpose of the present work was to bring together methods that had generated different patterns of results in order to determine whether those differences would persist if the same subjects were performing the two types of tasks. (Author)

THE MAIN OBJECTIVES OF THE ANALYSES INCLUDE--(1) A RESEARCH STUDY OF TECHNIQUES FOR THE EVALUATION OF ASSOCIATIVE AND COORDINATE MESSAGE RETRIEVAL METHODS. (2) THE PREPARATION AND ANALYSIS OF MACHINE-READABLE TEST CORPORA SUITABLE FOR EXPERIMENTS WITH ASSOCIATIVE MESSAGE RETRIEVAL METHODS. THESE CORPORA CONSIST OF APPROXIMATELY 10,000 MESSAGES AND…

THE OBJECTIVE OF THIS WORK IS TWOFOLD--(1) TO DEVELOP GENERALIZED PROGRAMS AND PROCEDURES FOR ACCEPTING LARGE VOLUME INFORMATION AND INCORPORATING IT AUTOMATICALLY INTO THE FILES OF THE MULTILIST SYSTEM. (2) TO DEMONSTRATE BY A SPECIFIC EXAMPLE THE SPECIAL ADVANTAGES OF USE OF THE QUERY LANGUAGE, FILE DIRECTORIES AND FILE MULTILIST STRUCTURE. THE…
