Introduction

COGENT is a graphical tool for building computational models and managing research programmes in cognitive modelling. It supports the development of a series of executable cognitive models, within an environment that interfaces a box and arrow style specification language with a symbolic modelling language.

The graphical interface allows the user to specify a model by drawing boxes and connecting them with arrows. By then specifying further details of the boxes, the user can execute or "animate" the theory. Figure 1 shows a typical COGENT box and arrow diagram.



Figure 1: A COGENT Box and Arrow Diagram

The different shapes of boxes in the diagram in Figure 1 reflect boxes with different properties or behaviours. For example, rectangular boxes with rounded corners correspond to buffers or boxes whose primary function is information storage. COGENT provides a range of configurable box types, as shown in Figure 2.

COGENT has been used to develop cognitive models in a range of domains, including:

Several other projects are in progress.
