Tests the relative efficiency and learning effect of text, pictures, and animation in online help systems, designing six versions of a help system for telephones. Presents operational information in text, pictures, or animation, with or without spatial information. Shows that presenting operational information via text was most efficient and that…

Describes the Educational Resources Information Center (ERIC) system, a national network of 16 specialized clearinghouses and several central ERIC service facilities. Notes that the ERIC system is charged with enhancing the database of educational resources by identifying hard-to-find materials. Explains briefly how to use ERIC and the educational…

With the availability of new technologies and changes in information processing, it is imperative that Extension's leaders look ahead and identify the role Extension will play in inventing its future. (JOW)

Presents the list-structure data model for dealing with sets of objects, which has ordering as its fundamental principle. An extended notion of patterns and several operators of the algebra are presented. Design issues that influenced the development of the language are described. (Contains 30 references.) (KRN)

Examines parallel computer architecture and the use of parallel processors for text. Topics discussed include parallel algorithms; performance evaluation; parallel information processing; parallel access methods for text; parallel and distributed information retrieval systems; parallel hardware for text; and network models for information…

Identifies four components of a good predictive lossless image compression method: (1) pixel sequence, (2) image modeling and prediction, (3) error modeling, and (4) error coding. Highlights include Laplace distribution and a comparison of the multilevel progressive method for image coding with the prediction by partial precision matching method.…

The ability of 31- to 36-month-old children to act in accordance with rules was assessed in 2 slightly different experiments using sorting tasks and knowledge tasks. Taken together, the results of both experiments imply a relatively rapid, age-related change culminating in the ability to systematically execute rules that require access to extant…

Business educators teach students to input, edit, print, file, reproduce, organize, manipulate, and use information to make business decisions. Business education, thus, seems the natural vehicle for training all information workers. (JOW)

Posits that intelligibility is a persistent problem in interactive multimedia and hypermedia. Describes the Art of Memory, a visual and symbolic mnemonic method used to map new information onto familiar and symbolically different structures. Presents the Art of Memory as a way to offer insight into intelligibility. (PA)

Describes heuristic-systematic information-processing model and risk perception--the two major conceptual areas of the analysis. Discusses the proposed model, describing the context of the data collections (public health communication involving cancer epidemiology) and providing the results of a set of three replications using the proposed model.…

This paper argues that the handicapping effects of blindness on children are specific to certain educational and social contexts, with the most substantive difficulties resulting from lack of convergent and complementary information through various sensory channels and the depressed speed of information processing. (Author/DB)

Examines the efficacy of using immediate and delayed feedback in generating improvement on a subsequent public speaking performance, for tasks which vary in information processing requirements. Indicates that immediate feedback intervention is more effective when automatic processing occurs, while delayed feedback produces greater change with…

The subject of this article is the frame problem, as conceived by certain cognitive scientists and philosophers of mind, notably Fodor for whom it stands as a fundamental obstacle to progress in cognitive science. The challenge is to explain the capacity of so-called informationally unencapsulated cognitive processes to deal effectively with…

Creativity is seen as a complex process of information processing within a defined cognitive realm, of "conceptual space," which defines the possibilities in terms of sensible judgments. Creative acts consist of novel reorganizations and combinations of information and challenge the boundaries of sense as defined by the space. Creativity is a…

The focus of "Synthesis", the most visible part of the information problem-solving process, varies depending on the original task. Organizing information and presenting information are the two forms of Synthesis and they are very important for the students as they can save time and effort, and do a better job, by using technology in meaningful…
