    The experiment investigates the perceptual-motor organization underlying children's catching performance when the demands on the postural system are varied. For this purpose, one-handed catching performance was observed under different postural constraints in children aged 9-10 years. Two groups of eleven participants, classified as either good or poor catchers, performed one-handed catches under three different postural conditions: standing, sitting, and standing while pressing a button positioned to a postural support aid (PSA). Results revealed, first, that when seated, poor catchers approached the level of the good catchers' performance. Second, poor catchers improved their performance by using the PSA, but not to the same performance as when sitting. Third, there was no effect of postural condition on the performance of the good catchers. The performance increase in the poor catchers is attributable to a combined change in functional postural sway and better timed movement of the catching hand, made possible by exploiting the extra surface support area afforded by sitting. © 2004 Elsevier B.V.
