| Abstract | This paper describes two ways in which events occurring in the peripheral musculoskeletal apparatus can shape or alter the temporal structure of ongoing movements. First, the biomechanical properties of a simulated, two-joint arm are shown to play a formative role in the creation of rhythmic, modal movement patterns. These patterns are interpreted as mutual entrainment phenomena between a pair of (highly) nonlinear oscillators. Second, peripheral haptic information has been shown in preliminary phase-resetting analyses to modulate the timing structure of rhythmic speech sequences. Implications of both sets of results for understanding the acquistion and performance of skilled movements are discussed briefly. |
