Bridging the gap: Dynamics as a unified view of cognition

Top-down dynamical models of cognitive processes, such as the one presented by Thelen et al., are important pieces in understanding the development of cognitive abilities in humans and biological organisms. Unlike standard sy mbolic computational approaches to cognition, such dynamical models offer t he hope that they can be connected vith more bottom-up, neurologically insp ired dynamical models to provide a complete view of cognition at all levels . We raise some questions about the details of their simulation and about p otential limitations of top-down dynamical models.
