Multisensory perception and action in 3-ball cascade juggling was investigated in intermediate-skilled performers by manipulating vision (full or lower field restricted) or ball weight (equal or different). There were main effects for both independent variables but no interactions. Manipulation of ball weight had a more pervasive effect on performance outcome, as well as central tendency and dispersion of kinematic measures of the juggling action. A common finding to both manipulations was that balls were tossed to higher zeniths, thus increasing parabola height and flight time. For intermediate-skilled jugglers, proprioception-haptics available when the balls were in the hands and vision of the balls and hands around the moment of ball toss and catch both make a contribution to the juggling action.
通过操控视觉（全视野或下视野受限）或球的重量（相等或不同），对中级水平的杂耍表演者进行三球级联杂耍中的多感官感知与动作研究。两个自变量均有主效应，但无交互作用。球重量的操控对表演结果以及杂耍动作运动学指标的集中趋势和离散度有更普遍的影响。两种操控的一个共同发现是，球被抛到更高的顶点，从而增加了抛物线高度和飞行时间。对于中级水平的杂耍者来说，当球在手中时可获得的本体感觉 - 触觉以及抛球和接球瞬间球与手的视觉都对杂耍动作有贡献。
