Introduction

COGENT is an X based tool for building computational models and managing research programmes in cognitive modelling. It developed out of a research project aimed at improving the tools and methodology of cognitive modelling. It supports the development of a series of executable cognitive models, using a graphical environment interfacing to a symbolic modelling language based on object-oriented extensions of the Sceptic programming language (Hajnal, Fox, & Krause, 1989; Cooper & Farringdon, 1993; Cooper, 1995; Cooper et al, 1996).

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 hierarchy of box classes is 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), and several other projects are in progress.
