COGENT is a Windows 95/NT tool for building computational models incognitive modelling.
It developed out of
a research project aimed at improving the tools and methodology of
cognitive modelling. It supports the development 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,
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, 1996), and several other
projects are in progress.
