Young The Cognitive Architectures and HumanComputer Interaction l~brkshop examined computational cognitive modeling approaches to human-computer interaction issues (HCI). Thefive major architectures and variations represented were briefly summarized. Participants compared approaches to a set of selected HCI problems and alternative solutions, and compared the strengths and weaknesses of the architectures. A list of additional issues was generated and discussed. Keywords: computational cognitive mod- phenomena, within architecturedefined boundaries. The ability to use a mechanism without needing to demonstrate its validity, has freed modelers to focus on how various cognitive mechanisms interact with particular instantiations of tools (such as the software interface) in accomplishing particular tasks. It is this freedom and concomitant power that has fueled the current interest in applying computational cognitive modeling to HCI tasks This workshop brought together 14 HCI researchers who have expertise in one or more cognitive architectures. Together, we sought to identify ways in which the choice of cognitive architecture bears on the practice and prospects for modeling in HCI. Represented architectures and approaches included
