Learning a New Bimanual Coordination Pattern: Reciprocal Influences of Intrinsic and To-Be-Learned Patterns

According to dynamic pattern theory, intrinsically stable bimanual coordination patterns affect, and are affected by, the acquisition of a new coordination pattern. In Experiment 1, subjects practiced either a 45 degrees or a 135 degrees relative phase pattern for 4 days; in Experiment 2, they practiced a 90 degrees relative phase pattern over 6 days. Retention tests were conducted 4 weeks after the last practice session in both experiments. …
