Recent developments and problems in human movement science and their conceptual implications

Journal/Book: Ecol Psychol. 1995; 7: 10 Industrial Ave, Mahwah, NJ 07430-2262. Lawrence Erlbaum Assoc Inc. 291-314.

Abstract: Behavioral, neurophysiological, and theoretical lines of research are briefly reviewed, opening to scrutiny a number of conceptual questions: What does it mean that the central nervous system controls a variable? In which sense can the central nervous system be said to use particular coordinate systems? What do we mean when we talk about levels of nervous control of movement? What are dimensions of behavior? Are planning and execution separate domains of movement science? To exemplify these issues, trajectory formation is discussed as a model system, around which answers to these problems can be attempted. The theoretical language used in chat attempt is that of the dynamic approach to understanding coordination. The role of ecological psychology in a renewed effort to arrive at a unified, here dynamic, account of action is discussed.
