Software

ACT-R the theory is embodied in ACT-R the software, as a set of functions and algorithms implemented in Common Lisp. Since the ACT-R implementation lives in Lisp, the aspiring cognitive modeler must also have access to some Lisp environment, or use the standalone version of the ACT-R Environment.

This page holds information about the current version of the software, ACT-R 6. For information about older versions of the software, you need to check out the older software page.

ACT-R 6

Here you will find all the information available about ACT-R 6.

ACT-R 6 version 1.3 [r563]

Updated February 15, 2008

It is available as a zip file or a disk image.

Note: the Mac version of the environment is only included in the disk image to keep the size of the zip file small.

See the QuickStart.txt file for startup instructions (that file can also be found in the docs directory of the distribution).

Standalone Versions

There are standalone versions of the ACT-R 6 environment for Windows and Mac OS X (PPC only right now).

These run ACT-R 6 without the need to have a separate Lisp application installed.

To install the Mac version follow the instructions in the Readme file of the disk image.

To install the Windows version just unzip the files and it should be ready to run (see the readme.txt file).

If you have any problems or questions please contact Dan.

Tutorial Units

The tutorial units and models are currently included with all of the ACT-R 6 versions above.

Other Material

The ACT-R 6 Reference Manual is now available directly and will be updated with each new software release.

The logs of the commits to the Subversion source code archive of ACT-R 6 are now available via LiveJournal, a text log or an atom feed.
