We distinguish diagrammatic from sentential paper-and-pencil representationsof information by developing alternative models of information-processing systems that are informationally equivalent and that can be characterized as sentential or diagrammatic. Sentential representations are sequential, like the propositions in a text. Dlogrammotlc representations ore indexed by location in a plane. Diogrommatic representations also typically display information that is only implicit in sententiol… Expand
Why Diagrams Are (Sometimes) Six Times Easier than Words: Benefits beyond Locational Indexing
An experiment in which participants solved three versions of Larkin and Simon’s simple pulley system problem with varying complexity suggests that the advantage of diagrams goes beyond the effects that locational indexing has on the processes of searching for items of information and the recognition of applicable rules.

A system that can understand diagrams, starting from the graphics primitives such as lines and polygons and resulting in symbolic and veridical representations of the diagram structure is built, based on Graphics Constraint Grammars. Expand
Equivalences in Euler-based diagram systems through normal forms
The form of information presented can influence its utility for the conveying of knowledge byaffecting an interpreter’s ability to reason with the information. There are distinct typesExpand
Using space to represent data: diagrammatic reasoning

The question about how humans employ diagrams, how they perceive them and how they draw conclusions, is certainly a challenging question, and given the complexity of the underlying cognitive processes it seems in fact useful to put their treatment into the centre of a classification scheme. Expand
Coordinating representations through programming activities: an example using Logo
The research literature has pointed to difficulties encountered by students in interpreting and establishing links between different types of representational registers. Here I present results from aExpand
Diagramming information structures using 3D perceptual primitives
The proposition that drawing three-dimensional shaded elements instead of using simple lines and outlines will result in diagrams that are easier to interpret is investigated and substructures can be identified much more accurately with shaded components than with 2D outline equivalents and remembered more reliably.

Image and Language in Human Reasoning: A Syllogistic Illustration
It is argued that much richer empirical evidence will be required to discriminate phenomenologically distinct reasoning processes than has hitherto been supposed. Expand
Diagrammatic Reasoning: An Artificial Intelligence Perspective

The common, and often implicit, assumption that if diagrams are so useful for human problem solving and are so apparent in human desire, then there must be analogous computational devices of similar utility is investigated. Expand
Toward an isomorphic diagram of the Backus-Naur form
Computer scientists studying formal languages have made use of a variety of representations to both reason, and communicate their ideas to others. Symbolic representations have proved useful forExpand
Graphical notations for syllogisms: How alternative representations impact the accessibility of concepts

  • J. Vis. Lang. Comput.
  • 2014
The comparison of the five notations reveals how their underlying representational schemes can substantially impact the effectiveness of the encoding of the core concepts of the knowledge domain; in particular whether the core domain concepts are readily accessible as perceptual inferences and thus the notations are semantically transparent.

Representational Types: A Tricode Proposal.
It is proposed that this principle is applied in a production system framework in which the relevant cognitive processes are those which interface declarative memory and production memory with working memory. Expand
Toward a Model of Text Comprehension and Production.
The semantic structure of texts can be described both at the local microlevel and at a more global macrolevel. A model for text comprehension based on this notion accounts for the formation of aExpand
Knowledge Compilation: Mechanisms for the Automatization of Cognitive Skills.
The development of a skill is traced from the point when it is initially being memorized and applied in a slow and halting fashion to the point where it has become fast and automatic through practice. Expand
Information-processing analysis of perceptual processes in problem solving.
The theory is particularized in a computer program to simulate the eye movements of subjects choosing a move in chess, and its consistency is shown with data on memory of chess positions and with existing knowledge of short-term memory parameters. Expand
What the Mind’s Eye Tells the Mind’s Brain: A Critique of Mental Imagery
This paper presents a critique of contemporary research which uses the notion of a mental image as a theoretical construct to describe one form of memory representation. It is argued that an adequateExpand
Principles of Economics
ECONOMICS admit of being reduced to principles more than other sciences dealing with human actions, for the reason which Prof. Marshall has thus expressed: “Wide as are the interests of which theExpand
Generalization Learning Techniques for Automating the Learning of Heuristics
Procedures are developed which permit a problem-solving program employing heuristics in production rule form to learn to improve its performance by evaluating and modifying existingHeuristics and hypothesizing new ones, either during an explicit training process or during normal program operation.

The results show that the proposed model is sufficient to generate excellent problem descriptions, that these markedly improve subsequent problem solutions, and that major components of the model are necessary for good performance. Expand
