A probabilistic approach is introduced to classify and diagnose erroneous rules of operation resulting from a variety of misconceptions ("bugs") in a procedural domain of arithmetic. The model is contrasted with the deterministic approach which has commonly been used in the field of artificial intelligence, and the advantage of treating the…

This technical report has two purposes. One purpose is to present an end product of a multi-year research investigation into the cognitive skills involved in performing intelligence analysis. The product is a "Handbook for Strategic Intelligence Analysis" developed for the United States Army Intelligence and Threat Analysis Center…

A study was conducted to test a model that conceives of long term memory as a propositional network of ideas made up of knowledge clusters and related subclusters. After two pilot studies suggested that recall order of ideas was unrelated to organization, the study investigated whether units of main and supporting ideas produced during…

The automatic/controlled processing theory proposal that the modification of long term memory (LTM) occurs only during controlled processing, and that stimuli can be automatically processed with no resulting LTM effect was tested in two experiments. In the first experiment, subjects were shown words while performing tasks involving either…

Children's increasing use of intentions and motives and decreasing use of outcomes to morally evaluate action are perhaps the most researched phenomena in moral cognition. However, relatively little is known about the acquisition of the ability to make moral evaluations and the processes involved. Based on the assumption that children's…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…

This paper reviews the aspects of cognitive science that relate best to using electrical and magnetic recording to understand the function of brain systems. It outlines a framework for relating cognitive activities of daily life (typing, reading) to underlying neural systems. The framework uses five levels of analysis: task, elementary operations,…

The development of moral judgment in 11-year-old girls is discussed in terms of the evaluation of role taking ability. (ST)

Procedural semantics models have diminished the distinction between data structures and procedures in computer simulations of human intelligence. This development has theoretical consequences for models of cognition. One type of procedural semantics model, called schema theory, is presented, and a variety of cognitive processes are explained in…

This report examines the theory that when people understand a text, they create a complex scenario (or model) within which the events described might plausibly occur. In order to study construction and revision of such models, five subjects were given difficult-to-understand texts, and were later asked to discuss the processing they went through…

This study tested the ability of two semantic-memory models, feature-comparison and network, to explain differences in information processing times. The feature-comparison model assumes that an item's meaning is held in semantic memory as a set of characteristic and defining features, while the network model assumes that semantic memory is…

This document discusses how the organization of instruction influences the encoding and structuring of new material in the memory and the subsequent transfer of such information to novel situations. A theory of instruction for problem solving that considers relevant cognitive variables and that specifies the conditions for productive learning is…

The first part of this paper on prose analysis explains how structural analysis of text can be used in reading research. This explanation focuses on three methodological uses of prose analysis: (1) the identification of the content and organization of the text for use in a scoring system, (2) the measurement of variations between the text and the…

This paper presents an overview of current research on causal attributions for success and failure with a focus on theoretical developments since the Weiner et al (1971) paper and applications which have been made using this theoretical model. Theoretical advances include more sophisticated measurement of causal attributions, applications of the…

If overattribution--the tendency for observers to think actors' attitudes match their behaviors even when behaviors are not freely performed--results from the fundamental attribution error, then observers must believe the coerced behavior is attributionally informative. This assumption was tested by (1) investigating the extent to which attitude…
