We have just published a paper at EBR Online First that many members of ISEP may find of interest. The title is “The role of intentionality in the performance of a learned 90° bimanual rhythmic coordination during frequency scaling: data and model”. The initial studies done by Scott Kelso and colleagues entailed spontaneous mode transitions (180° to 0°) occurring during frequency scaling. To our knowledge, the current study is the first investigating frequency scaling with a learned coordination. The catch here is that a switch from 90° to 0° or 180° would entail a change in information. There is also a question as to the role of correction. Is spontaneous transition possible, as would be captured by a strictly continuous time dynamical model? If nothing else, one sees how these problems become increasingly complicated. In the end, a truly perception/action dynamical model does the trick! If you do not have access to EBR online, contact Geoff at gbingham@indiana.edu
