Abstract

Current research suggests that non-visual perception of the spatial orientation of body segments is tied to vectors representative of their mass moment distribution (v_mm). Our question was whether the relative orientation of v_mm of right and left hands (Δv_mm = v_mm left - v_mm right) constitutes haptic information supporting bimanual coordination and, if so, how it contributes to coordination dynamics. Blindfolded participants coordinated the motions of a pair of cross-shaped, hand-held pendulums that were either symmetrically loaded (Δv_mm = 0) or asymmetrically loaded (Δv_mm ¬= 0). The sign and magnitude of Δv_mm, in particular of the first moment vector, systematically affected the pattern of coordination (indexed by mean relative phase φ), but not its stability. These results suggest that (1) Δv_mm specifies a frame of reference about which coordination is organized; and (2) that the changes in pattern were a function of the experimentally induced biases in this perceptual frame of reference and not a function of a functional asymmetry akin to detuning. The implications of the findings to the understanding of perceptual regulation of interlimb coordination were discussed.
