This study examines if putting a hand in a basketball shooter's face procides more effective defense if the hand is waved with fingers open or held stationary with fingers closed. Surveyed undergraduates strongly favored the waved-hand strategy, independent of extent of exposure to basketball. Yet, our results demonstrate that defense is superior with the stationary-hand strategy. People appear to assume that the added complexity or "visual noise" of motion increases distractibility. Our findings support that a stationary hand more effectively blocks visibility. A moving hand acts as a partially-occluding moving surface that allows greater visibility.
