COGENT on Windows: Finally we have produced self-installing executable packages to simplify COGENT installation on windows machines. Version 2.3.9 and 2.4.2 are now available. (January 12, 2012)
COGENT on Windows 7: We have had several queries concerning problems with running COGENT 2.3 under Windows 7. COGENT 2.3 does work, but requires a minor patch on some Windows 7 systems. If you find that you can create models but they do not run, then please download the replacement process.pl library and install it over the equivalent file from the original distribution. On a standard distribution, this file should be in the folder C:\Program Files\COGENT 2.3.9\lib\classes\. Please e-mail us if continue to have difficulties. (November 14th, 2011)
COGENT on 64 bit Linux: COGENT 2.4 #0 is now available for 64 bit linux systems with GKT+2 widget libraries (e.g., modern Ubuntu distributions). It can be downloaded from the usual place. (November 14th, 2011)
COGENT on Mac OSX Lion: COGENT 2.4 #0 is now available for Mac OSX as a universal binary (also using the GKT+2 widget libraries). It can be downloaded from the usual place. (November 14th, 2011)
COGENT Version 3.0: COGENT Version 3.0 is still in the final stages of development and we hope to release it by the end of 2011. This version, which uses the GTK+2 widget set, contains a number of improvements to the interface and to diagram drawing, as well as some efficiency improvements in the Windows version. (November 14th, 2011)
COGENT Version 2.3: COGENT Version 2.3 #9 for Windows 95/98/NT/2000 etc., LINUX and Mac OS/X is now available. See the documentation for new features and some significant bug fixes. Existing users please note that if you upgrade from any sub-version of 2.2 or 2.1 you will also need to upgrade your registration key. (November 6th, 2009)
COGENT Tutorial at ICCM 2007: A tutorial on COGENT was held in Ann Arbor, Michigan, immediately prior to the International Conference on Cognitive Modelling. Tutorial materials and instructions for participants are available from the tutorial section of this web site. (August 3rd, 2007)
COGENT Version 2.3: COGENT Version 2.3 #8 for Windows 95/98/NT/2000 etc., LINUX and Mac OS/X is now available. See the documentation for new features and some significant bug fixes. Existing users please note that if you upgrade from any sub-version of 2.2 or 2.1 you will also need to upgrade your registration key. (April 13th, 2006)
Bug Reporting: The COGENT bug reporting system has been given an overhaul, and is now a little more streamlined. Please check the current bug status report before reporting any bugs.
COGENT Version 2.3: As of Version 2.3, COGENT is being released under the Gnu Public Licence. To access the COGENT source, go to the download section of this site.
COGENT on Mac OS X: It is now possible to run COGENT on
Mac OS X. See the online
installation instructions for further details. Please note that COGENT on
the Mac requires the X11 windowing system (and the X in "X11" has nothing to
do with the X in "OS X"). X11 is available at no charge. Recent versions of OS
X include X11 on the installation disk, but the installation instructions
provide details on how it may be obtained.
Mac users who can successfully create and edit models but who experiencing problems running those models may also need to install the libdl library. Please contact us directly if you have any problems.
COGENT on Solaris/IRIX/etc.: Users looking for Solaris and other non-LINUX UNIX versions of COGENT are advised to try building COGENT from the source (and please do contact us if you have difficulties).
Model Archive: The COGENT model archive includes archives of all models developed in the text Modelling High-Level Cognitive Processes, published by Lawrence Erlbaum Associates in 2002.
The COGENT Book: The COGENT book (Cooper, R.P. (2002). Modelling High-Level Cognitive Processes) is available from Lawrence Erlbaum Associates. The book uses COGENT to develop models in a range of domains (including problem solving, reasoning, decision making, memory, sentence processing), and includes plenty of exercises and project material.
COGENT Version 2.1 is still available for Linux and Windows platforms. The release includes many new features and some significant bug fixes compared with Version 2.0, and corresponds exactly to that used in the text, Modelling High-Level Cognitive Processes. To download, see the downloads section.
Further Announcements: Some previous announcements are still available.
