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
TLDR
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.

INFORMATIONAL DIAGRAMS IN SCIENTIFIC DOCUMENTS
TLDR
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
  • B. Gottfried
  • Computer Science, Medicine
  • Cognitive Processing
  • 2012
TLDR
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
TLDR
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
TLDR
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
  • P. Olivier
  • Computer Science
  • Artificial Intelligence Review
  • 2004
TLDR
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
  • P. Cheng
  • Computer Science
  • J. Vis. Lang. Comput.
  • 2014
TLDR
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.
