LEARNING A NEW BIMANUAL COORDINATION PATTERN - RECIPROCAL INFLUENCES OF INTRINSIC AND TO-BE-LEARNED PATTERNS

According to dynamic pattern theory, intrinsically stable bimanual coo rdination patterns affect, and are affected by, the acquisition of a n ew coordination pattern. In Experiment 1, subjects practiced either a 45 degrees or a 135 degrees relative phase pattern for 4 days; in Expe riment 2, they practiced a 90 degrees relative phase pattern over 6 da ys. Retention tests were conducted 4 weeks after the last practice ses sion in both experiments. Performance on both the in-phase (0 degrees) and anti-phase (180 degrees) patterns was also measured on each day. Contrary to predictions, the experiments revealed that reciprocal effe cts between the intrinsic patterns and the new pattern were only tempo rary, and did not affect learning in any permanent way. As well, learn ing a new pattern was not differentially affected by its relation to a n intrinsic pattern.
