ABSTRACT
The following introduces CaDaDis, an extension to the architecture-independent VISTA toolkit. CaDaDis creates visible accounts of cognitive model behavior through a set of Categorical Data Displays. It includes a standard Pert Chart showing tasks by category (or resource), a Nonstandard Pert Chart that shows the temporal dependencies, and a Gantt chart that helps show occurrences of agent events along a time line. Perhaps most usefully, it can display categorical and numeric data generated by models as they run. Structured messages are sent on behalf of the cognitive model by several example script-based interfaces. This paper presents a series of examples of CaDaDis with three different cognitive architectures. The displays, for example, show that the sample models included in the Soar distribution have different structures.
