There has been tremendous growth recently in theories that attempt to provide more comprehensive accounts of the foundational mechanisms of human cognition. Such theories have taken a variety of forms, and have focused on different levels of analysis. The diversity is important and necessary, but can serve as a barrier to interaction, comparison, and integration, even at venues like the Annual Meeting of the Cognitive Science Society that should foster such dialogue. This workshop is intended to bring together individuals working on integrative models of human cognition, to emphasize shared motivations and goals. Ultimately, building scientific communities that bridge levels of analysis, methodologies, and theoretical approaches to work toward more comprehensive theories will be critical to the addressing the central goal of the Cognitive Science Society – understanding the nature of the human mind.
