To see or not to see: effects of visual feedback on performance and intuitions of quarterbacks in American football

We investigated the ability of quarterbacks in American football to intercept a moving receiver with a football in occluded and normal viewing conditions, and whether they can accurately predict their own success. Quarterbacks were successful in almost 80% of the trials in the occlusion condition, statistically as successful as in the normal viewing condition. Quarterbacks' predictions of their own success accounted for little variance in actual success. We propose that quarterbacks may attempt to generate a constant target-heading angle between where the football is thrown and the receiver, which may explain the high success rate in the occlusion condition.
