| Abstract | Task interference methods and phase transition curves to quantify task interference in tasks that may have 2 components were applied to the coordination of hand transport and grasp aperture components in the reaching and grasping movements to pick up things. Five subjects made cyclical movements that involved either composite reaching or just the transport or grasp component in isolation, according to condition. Results suggest a functional linkage between grasp aperture and hand transport in normal prehensile movement. |
