SPATIOTEMPORAL ORGANIZATION OF NATURAL PREHENSION

An information-based model of natural prehension is proposed that can account for a large number of experimental findings without taking recourse to prestructured movement plans. It is suggested that coordination of the transport and grasping components is guaranteed because both components are ultimately geared to the same information specifying time-to-contact between the hand and the object to be grasped, and that therefore no special control structures responsible for this coordination are required.
