Beyond embodiment: Cognition as interactive skill.Paul P. Maglio -1997 -Behavioral and Brain Sciences 20 (4):753-754.detailsThe target article makes a compelling case for the idea that agents rely on the world for external memory in fast-paced perceptual tasks. As I argue, however, agents also rely on the external environment for computational hardware that helps to keep cognitive computations tractable. Hence the external world provides not only memory for computations involving perceptual system actions, but it provides domain-level actions that figure in cognitive computations as well.
