| summary | The notion that a few ‘movement primitives’ underwrite complex (human) movements is pertinent to various theoretical perspectives on motor control. Consequently, movement primitives have been classified according to different (and often empirically driven) criteria. Departing from the perspective that dynamical systems can be unambiguously described in phase space, we propose a movement primitive taxonomy based on phase flow topology. The existence of two qualitatively different movement primitives governing discrete and rhythmic behavior has been debated repeatedly in the literature. We provide evidence testifying to the existence (and utilization by humans) of both primitives through a computational analysis and a study involving human participants. We furthermore argue that one other movement primitive likely exists. |
