Abstract
Conventional views of motor control, which state or imply that it is a deterministic system, are being challenged by the recognition that the stochastic properties of motor control may offer clues to some of its operations. This paper considers evidence that there exists a general property of trajectory formation which is a consequence of the inherent variability of movements. Specifically, the amplitude of the initial sub-movement of motions containing two or more such sub-movements is planned so as to take into account its spatial variability. Examples are given of cases where such a principle might be expected to apply, and the usefulness of this phenomenon for examining individual and strategy differences in aiming tasks is discussed.
