Intentional switching between patterns of bimanual coordination depends on the intrinsic dynamics of the patterns.

摘要: Two predictions arising from previous theoretical and empirical work which demonstrated that spontaneous changes of bimanual coordination patterns result a loss pattern stability (i.e., nonequilibrium phase transition) were tested: (a) the time it takes to intentionally switch one another depends on differential themselves; (b) an intention, defined as intended behavioral pattern, can change dynamical characteristics, e.g., overall patterns. Subjects moved both index fingers rhythmically at six movement frequencies while performing either in-phase or antiphase finger coordination. On cue auditory signal, subjects switched ongoing other pattern. The relative between two was used characterize coordinative taken patterns, switching time, fluctuatio...
