AbstractThere is evidence that experience of the sensory consequences, in the absence of practice of the required motor commands, is sufficient to learn new bimanual coordination patterns. This was shown through improvements of an “incongruent” group who practiced a desired 30° phase offset between the limbs while one limb was weighted such that the desired phase relation was achieved when synchronous motor commands were sent to the limbs (Atchy-Delama et al., 2005). In addition to testing a similar “incongruent” and “congruent” group (i.e., no weight), we extended this experiment by removing visual feedback during practice, and by including an auditory modeling and passive guidance group. All groups showed improvement, except for the modeling group. The passive guidance group made more errors in post-tests than the congruent and incongruent groups. Only the congruent group increased the amount of time around 30º after practice. Active experience of the sensory consequences combined with practice sending appropriate motor commands is the most effective method for learning, even though strategic improvements can be attained without experience of the latter.
