Asymmetrical transfer of training between hands: implications for interhemispheric communication in normal brain.

abstract：:In two experiments, subjects imagined themselves performing a tracking task under a massed practice schedule. After interpolated rest or no rest, subjects actually performed the criterion task. Some subjects' imagery was augmented with sounds that matched the temporal characteristics of the criterion task. These subje...
