This study was designed to investigate the effects of modeling or training with and without rule provision on the employment of strategies in solving four-dimensional, discrimination-learning problems. Subjects were 144 second and sixth-grade children from the New York City Public Schools. The blank-trial hypothesis testing paradigm was used. The…

Discusses impact of three selected command language facilities (positional or free text operations, crossfile searching, term frequency analysis--ZOOM) on the man-system interface in relation to operational online information retrieval (IR). A cognitive IR model, searchers' knowledge structures, and searching with different types of command…

Experienced Physicists solve simple textbook problems differently from beginning students. This paper describes these differences using a computer-implemented model that "learns." The research is set in the the context of modern computer-processing psychology, and is related to other work relevant to help people know and learn…

Described are the historical uses and research involving the discipline of artifical intelligence. Topics discussed include: symbol manipulation; knowledge engineering; cognitive modeling; and language, vision and robotics. (Author/DS)

Reviews "Levels of Cognitive Development," which presents a theory of cognitive development integrating discrimination- learning research with understanding of higher cognitive processes. Argues that strengths include its presentation of systematic research and providing continuity between past and present models. Weaknesses include…

This article discusses problems in the psychological processing theory for learning disabilities assessment and describes the development and potential use of an interactive diagnostic system for testing students' processing skills for learning disabilities. (AEF)

In the last of a three-part series, this study examined the information processing patterns of postsecondary American Indian/Alaska Native students attending community and tribal colleges in the Southwest. Using a survey design, students completed the Kolb Learning Style Inventory, the Briggs and Myers Myers-Briggs Type Indicator, and the Oltman,…

This paper describes the use of adaptation patterns in the task of formulating standards for adaptive educational hypermedia (AEH) systems that is currently under investigation by the EU ADAPT project. Within this project, design dimensions for high granularity patterns have been established. In this paper we focus on detailing lower granularity…

This paper examines the dual coding hypothesis, a model of the coding of visual and textual information, from the perspective of a mass media professional, such as a teacher, interested in accurately presenting both visual and textual material to a mass audience (i.e., students). It offers an extension to the theory, based upon the various skill…

Schema theory may be significant in determining if and how news audiences process information. For any given news topic, people have from none to many schemata (cognitive structures that represent organized knowledge about a given concept or type of stimulus abstracted from prior experience) upon which to draw. Models of how schemata are used…

A model of cognitive operations that children use in reading and comprehending a sentence was tested by using Sternberg's independent-process analysis on 64 second and fifth graders who were either high- or low-ability readers. Three specific component processes were examined: a decoding process, a word meaning process, and a comprehension…

Any theory of information processing must address both what is processed and how that processing takes place. Most studies investigating variables which alter physical dimension utilization have ignored the large individual differences in selective attention or cue utilization. A paradigm was developed using an individual focus on information…

Three environmental elements--messages, events, and perceived consequences of choices--cause varying amounts of stress on an individual and affect his capacity to deal with his environment. There is a nonmonotonic relationship between environmental pressures ("event press") and persuasibility in that the number and importance of…

Six alternative models of the ways in which individuals accept and organize information from potential sources are proposed. Parameter estimates were obtained from experiments testing the effect of evaluations of performance upon an individual's conception of his own, and others', ability to perform specific tasks. Then the models were tested…

The author presents a decision-making model for women who are in the process of making career decisions and choices. Implications for going through this process are discussed. (HLM)
