The Massive Redeployment Hypothesis

Description: The massive redeployment hypothesis (MRH) is a theory about the functional organization of the human cortex, offering a middle course between strict localization on the one hand, and holism on the other. Central to MRH is the claim that cognitive evolution proceeded in a way analogous to component reuse in software engineering, whereby existing components—originally developed to serve some specific purpose—were used for new purposes and combined to support new capacities, without disrupting their participation in existing programs.

MRH suggests that in order to determine the functional role of a given brain area it is necessary to consider its participation across multiple task categories, and not just focus on one, as has been the typical practice. Among other illustrations of the fruitfulness of this approach is some preliminary work on understanding the functional role of left angular gyrus in both math cognition and finger gnosia.

Neuro-Image based Co-Activation Matrix (NICAM) database project

Description: This project involves compiling large numbers of brain imaging (primarily fMRI) studies and applying some simple data mining and graph theory based analytical techniques to investigate functional cooperation between brain regions. Applications of the project include understanding the basic functional structure of the cortex, and relating fMRI to EEG data to support such medical applications as epileptic seizure prediction. A special project website can be found here.

Brain Mechanisms Supporting the  Understanding of Action Sentences

Description:  The project uses state-of-the-art neuroimaging techniques in conjunction with computational modeling to investigate the brain mechanisms that support language understanding. Initial experiments will investigate the action-sentence compatibility effect.

The Fundamentals of Embodied Cognition

Description:  Embodied Cognition is an approach to understanding the mind that treats cognition as a coordinated set of tools evolved by organisms for coping with their environments. This approach foregrounds agency and environmental interaction over internal symbol manipulation (although it need not deny the importance of the latter). To find out what embodied cognition has to do with AI, see a canned history of AI.

The Guidance Theory of Representation 

Description:  The guidance theory of representation is an action-oriented theory of representation, according to which content is to be cashed out in terms of action-guidance, and intentionality is grounded in the natural directeness of action. The guidance theory offers a way of fixing representational content that gives causal and evolutionary history only an indirect (non-necessary) role, and allows for an account of representational error, expressed in terms of failure of action, that does not rely on any such notions as proper function, ideal perceptual/epistemic conditions, or normal circumstances. It can help bridge the gap between the embodied approach to cognition and the more representation-oriented schools of cognitive science.

The Metacognitive Loop

Description: An investigation of the thesis that metacognitive monitoring and control (in a form we call the metacognitive loop, or MCL) can play an important role in improving the perturbation tolerance of real-world agents, that is, their ability to detect and recover from errors or unexpected changes. We have shown that adding an MCL component can improve the performance of a diverse range of systems from natural-language human-computer interfaces to simple Q-learners. A more specialized project along these same lines is an investigation into the use of metalanguage in conversation, and its role in helping maintain the fluidity, flexibility and error-tolerance of human-human dialog

The Multiple Modes Theory of Epistemic Openness

Description:  The multiple modes theory of epistemic openness, holds that embodied agents are more epistemically porous than is generally pictured, open to the world via multiple channels, each operating for particular purposes and according to its own logic. Among the most important of these modes of epistemic openness is our physical intervention in the world, which is not (in all its aspects) theory-laden in the manner of visual perception, and which therefore can serve to ground our knowledge in a way that vision alone cannot. Thus, for instance, this implies that symbol anchoring is grounded in our ability to interact with and manipulate the objects in one's environment.

The Roots of Self-Awareness

Description:  An investigation of the structural underpinnings of self-awareness, including both an abstract, logical account of how to build a genuinely self-referring artificial agent, and a biological account of the role of somatoception in supporting and structuring self-awareness in general.
