Complex patterns of interlimb coordination, such as multifrequency relationships of 1:2, 2:3, or 3:4, are difficult to perform intentionally without extensive practice. The current study investigated whether these patterns might nonetheless occur spontaneously given an appropriate balance between the movement frequencies, or oscillatory periods, of an individual's movements and a visual-environmental stimulus. In order to test this, participants swung a fixed-period wrist-pendulum while observing an oscillating computer-generated stimulus. Results indicated that at given differences in period, 1:2, 2:3, and 3:4 coordination patterns emerged between the participant and stimulus. This suggests that large period differences do not altogether prevent the emergence of rhythmic visuomotor coordination, but instead provide the opportunity for complex patterns of coordination to emerge spontaneously.
复杂的肢体间协调模式，如1:2、2:3或3:4的多频率关系，如果没有大量练习，很难有意地表现出来。当前的研究调查了在个体运动的频率或振荡周期与视觉环境刺激之间达到适当平衡的情况下，这些模式是否仍可能自发出现。为了测试这一点，参与者在观察计算机生成的振荡刺激时摆动固定周期的手腕摆锤。结果表明，在给定的周期差异下，参与者与刺激之间出现了1:2、2:3和3:4的协调模式。这表明，较大的周期差异并不会完全阻止有节奏的视觉运动协调的出现，反而为复杂的协调模式自发出现提供了机会。
