Stan Franklin, PhD: Consciousness, LIDA Model of Cognition and a Non-linear Dynamics View
As always, I’m thinking about how minds work. Our evolving answer to that question is in the form of a broad based, systems level cognitive model at a more conceptual level than brains, but still based on the underlying neuroscience.
Cognitive neuroscience can’t be studied at the level of neurons and synapses. How then should it be studied? An answer is beginning to emerge. A non-linear dynamics view, a la Freeman, Kelso and Buzsaki , applied to Fuster’s cognits, may well do the trick.I’m inspired by all of those mentioned above, but most significantly by Bernie Baars.
athematician turned computer scientist turning cognitive scientist, Stan Franklin holds the W. Harry Feinstone Interdisciplinary Research Professorship at the University of Memphis, was a winner of its Eminent Faculty Award, and was a founder of its Institute for Intelligent Systems. Wanting to know how minds work — human minds, animal minds and, particularly, artificial minds — motivates his research.
For some years he’s worked on “conscious” software agents, that is, autonomous agents modeling Global Workspace Theory, a psychological theory of the role of consciousness in cognition. Implementing the broad, integrative LIDA model of cognition, these agents conceptually and computationally model human and animal cognition, and provide testable hypotheses for cognitive scientists and neuroscientists. This endeavor, funded by the US Navy, has been the subject of some sixty papers in scientific journals and reviewed conference proceedings. His MS and PhD are from UCLA, his undergraduate degree from the University of Memphis. He has authored or co-authored some hundred and fifty academic papers that have been cited almost 5000 times. His Artificial Minds, published by MIT Press and still in print, was a primary selection of the Library of Science book club, and has been translated into Japanese and Portuguese.
He serves on the editorial boards of seven international professional journals including Topics in Cognitive Science, the International Journal of Machine Consciousness, the Journal of Mind Theory, Biologically Inspired Cognitive Architectures, and the Journal of Artificial General Intelligence. Stan has organized or given plenary addresses at major conferences and workshops, and has mentored twenty students to their PhDs. He currently serves on the IEEE CIS Technical Committee for Autonomous Mental Development and on the IEEE CIS Task Force on Towards Human-like Intelligence.
Most importantly, Stan leads the efforts of the Cognitive Computing Research Group at the University of Memphis, and beyond, in its development of the broad-based, systems level, conceptual and computational, LIDA model of cognition. It’s our ongoing, but unending, ever evolving, ever more successful, attempt to answer the question, “How do minds work?”

n autonomous agent senses and acts upon its environment in the service of its own agenda. An autonomous agent with human-like cognitive capabilities is called a cognitive agent. By a “conscious” software agent, we mean one designed within the constraints of Bernard Baars’ Global Workspace Theory of consciousness and cognition. The CCRG’s research revolves around the design and implementation of cognitive, sometimes “conscious,” software agents, their computational applications, and their use in cognitive modeling.
Like the Roman god Janus, cognitive computing projects can have two faces, their science face and their engineering face. The science face fleshes out the global workspace theory of consciousness into a full cognitive model of how minds work. (Please see the tutorial.) The engineering face of cognitive computing explores architectural designs for software information agents and cognitive robots that promise more flexible, more human-like intelligence within their domains. This fleshed out global workspace theory is yielding hopefully testable hypotheses about human cognition. The architectures and mechanisms that underlie intelligence and consciousness in humans can be expected to yield information agents, and cognitive robots that learn continualy, adapt readily to dynamic environments, and behave flexibly and intelligently when faced with novel and unexpected situations. Applications, both in progress and planned, are to various fields, including cognitive robotics and querying image databases with images rather than text.
