COGENT Model Archive
Models for use with COGENT Version 2.X on UNIX, Mac OS X and Windows
This page contains links to miscellaneous models developed
within COGENT Version 2.X. The models are presented as within research
programmes as downloadable COGENT archives. They are given in two formats: the
CAR format (COGENT's own non-compressed format), and the TGZ format (a
UNIX-derived format that is compressed). If you are using COGENT on Windows,
you must use the CAR format. If you are using COGENT on UNIX or Mac OS X you
can use either format.
The version of COGENT used to create each archive is given
alongside the archive. As a general rule, a later version of COGENT (e.g.,
Version 2.2) will open any archive created by an earlier version (e.g.,
Version 2.0). If you have trouble opening an individual archive, please ensure
that you have an appropriate version of COGENT.
Note also that all models developed and explored within
Modelling High-Level Cognitive Processes
may be used with COGENT Version 2.1 or later.

Installing the models
- Download the relevant archive and save it in your archive directory (e.g.,
by right-clicking on the link and selecting "Save Link As..." or "Save Target
As..." and then specifying your archive directory as the location of the save
command).
- Start up COGENT and select "Archives..." from the top menu bar. The
downloaded file should appear on the right panel of the archive browser.
- Select the file and click on the "<< Extract <<" button.
- Close the archive browser and the downloaded archive should appear as a
new research programme in COGENT's list of research programmes
