The central interest of research in the Action Lab is the acquisition and control of goal-directed human movements. What organizational principles are at work in movement coordination? What principles guide the acquisition of novel skills? Specifically, our research focuses on the acquisition of novel perceptual-motor skills and on the manipulation of complex objects. The theoretical framework that pervades our studies interprets the actor as a dynamical system, which is high-dimensional, nonlinear, and capable of producing coordinated and adaptive actions. Our research pursues a three-pronged research strategy consisting of:

  1. an empirical component with behavioral experiments on human subjects using virtual environments,
  2. theoretical work which develops mathematical models of the behavioral task using dynamical systems, and
  3. brain imaging and stimulation studies that investigate the cerebral activity accompanying coordinated actions.

More recently, we have extended these experimental paradigms to individuals with neurological disorders such as stroke and dystonia, and to the elderly.
