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.
