Abstract: | An experiment was conducted to determine whether multi-frequency continuous bimanual circling movements of varying difficulty
(1:2. 2:3, 3:4, and 4:5) could be effectively performed following relatively little practice when on-line continuous relative
velocity feedback is provided. The between-subjects results indicate extremely effective bimanual multi-frequency performance
for all coordination patterns with relatively stable and continuous movements of both limbs. The findings suggest that the
previous performance effects using Lissajous feedback with reciprocal movement can be extended to circling movements using
on-line relative velocity feedback. Contrary to the long-held position that these coordination patterns result in increasing
difficulty, we failed to find systematic relative velocity error, variability, or bias differences between the participants
performing the various multi-frequency coordination patterns. Indeed, coordination error, variability, and biases were remarkably
low for each of the tasks. The results clearly indicate the ease with which participants are able to produce bimanual coordination
patterns typically considered difficult if not impossible when salient visual information is provided that allows the participants
to detect and correct their coordination errors. |
