在球杂耍的学习过程中，习得性协调模式存在显著的个体差异。以往的研究表明，在杂耍新手中观察到的协调模式大致可以分为两类：高比率模式，即持球时间相对较长；低比率模式，即持球时间相对较短。为了解释这些协调模式的差异，我们研究了杂耍新手在控制杂耍动作时采用的锚定策略。高居住比协调模式的时间变异性低于低居住比协调模式，而低居住比协调模式的空间变异性又低于高居住比协调模式的空间变异性。这些发现表明，杂耍新手协调模式的个体差异，以及他们的学习路径，是由他们所采用的控制策略的差异造成的。
The learning process of ball juggling is characterized by considerable individual differences in acquired coordination patterns. Previous research has shown that the coordination patterns observed in novice jugglers can be roughly divided into two classes: the high ratio pattern, in which the ball is held for a relatively long time, and the low ratio pattern, in which the ball is held for a relatively short time. To account for these differences in coordination patterns, we examined the anchoring strategies employed by novice jugglers for controlling the juggling movements. Analyses of the correlation between coordination patterns and selected spatiotemporal variabilities revealed that the coordination patterns with a high dwell ratio had lower temporal variability than patterns with a low dwell ratio, which in turn had lower variability of spatial variables than patterns with a high dwell ratio. These findings indicate that individual differences in the coordination patterns adopted by novice jugglers, and hence their learning paths, result from differences in the control strategies employed.
