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. The boxes within a COGENT model may be of various types. COGENT provides a range of configurable box types, as shown in Figure 1.

COGENT has been used to develop cognitive models in a range of domains. These include child memory (Barreau, 1997; Miller, 1996), judgement and decision making (Fox & Cooper, 1997; Cooper & Fox, 1997; Yule, Cooper & Fox, 1998), multicolumn addition (Cooper, 1996), lexical concept combination (Cooper & Franks, 1996) and kinaesthetic acuity training (Sims & Morton, 1998), reasoning (Cooper, Yyle, Fox & Sutton, 1998), problem solving (Cooper, to appear) and sentence processing (Cooper, to appear), and several other projects are in progress.
