Thirty-Second ACT-R Workshop

The 32nd Annual ACT-R Workshop will take place on Tuesday July 29, 2025, as part of the MathPsych/ICCM conference. The general theme is the long-term future of cognitive architectures and unified theories of cognition. The sessions will last 1hr15′ and will be devoted to specific topics. Each session will start with a 20′ presentation to introduce the topic, followed by brief statements from each panel member then an open discussion involving all workshop attendees.

Virtual attendance will be available on Zoom (link will be provided closer to the event), and recordings of the workshop will be made available afterwards. Contact cl@cmu.edu with comments and inquiries.

Times listed are Eastern Daylight Time.
