Suggests that instructional theory is possible, but it should concern itself only with narrowly circumscribed local instructional situations, relatively small chunks of curriculum for relatively small segments of the educational population. (Author/AM)

Describes alternative theoretical positions regarding (a) the component information processes used in analogical reasoning and (b) strategies for combining these processes. Also presents results from three experiments on analogical reasoning. (Author/RK)

Attempts to clarify the concepts of model, simulation, and game on a theoretical basis, with emphasis on application in the field of computer assisted instruction. (DD)

Research supported in part by a United States Public Health Service Grant from the National Institute of Mental Health. (VM)

Several different conceptions of the relationship between learning and development are considered in this article. It is argued that dialectical and ecological developmental orientations might provide a useful basis for synthesizing the contrasting frameworks of the operant, information processing, learning theory, and knowledge acquisition…

Defines a "communicate"--the objectification of a subject's internal model of the object of reality by means of a certain set of physical signs--and examines its information value with relation to intelligent systems. (CWM)

When shown a pair of digits and asked to select the larger of the two, subjects make their choice more quickly as the numerical difference between the digits increases. Presents and tests a semantic coding model that can explain this and all previous results. (Editor)

This research presents an integrative theoretical framework to explain and to predict psychological changes achieved by different modes of treatment. This theory states that psychological procedures, whatever their form, alter the level and strength of "self-efficacy". (Editor/RK)

Presents a single framework for conducting topic analysis that performs both topic identification and text segmentation. Key characteristics of the framework are: representing a topic by means of a cluster of words closely related to the topic; and employing a stochastic model, called a finite mixture model, to represent a word distribution within…

Shows how different types of process schematics depict changes in state in significantly different ways, emphasizing differently types of information and thus defining event phenomena differently. Provides extension activities to help students understand process schematics. (MG)

Uses Third World development campaigns to examine how current interpretations of the interactive model in communication have confounded two dimensions of communications--information processing and social relationship. Suggests an analytic framework for feedback using a revised interpretation of the interactive model. (MM)

Theoretical/empirical foundations on which reaction times are measured and interpreted are discussed. Models of human information processing are reviewed. A hybrid procedure and analytical framework are introduced, using a speed-accuracy decomposition technique to analyze the intermediate products of rapid mental processes. Results invalidate many…

Proposes an information retrieval system based on a hybrid model consisting of an inductive learning and neural network system. Evaluates the system's responses to incomplete queries and inconsistent indexing. Query terms, discriminant descriptors, and the American Documentation Institute's query and document titles used in the evaluation are…

Surveys theoretical and practical issues associated with pictorial information retrieval. Concentrating on still and moving pictorial forms of the visual image, this paper focuses on indexing pictorial material and discusses four models of pictorial information retrieval corresponding with permutations of the verbal and visual modes for the…
