The student athletes completed more successful crossings than the nonathletes, by a significant margin, a result that might be expected of those in peak physical condition. But what was surprising — and thought-provoking — was that their success was not a result of their being quicker or more athletic. They walked no faster than the other students. They didn’t dash or weave gracefully between cars. What they did do was glance along the street a few more times than the nonathletes, each time gathering slightly more data and processing it more speedily and accurately than the other students.
“They didn’t move faster,” said Art Kramer, the director of the Beckman Institute and a leader in the study of exercise and cognition, who oversaw the research. “But it looks like they thought faster.”
... the finding did have a certain intuitive logic. “To the extent that athletes, in their sport, must routinely make split-second decisions in often very complex environments (e.g., whether to pass or kick the incoming soccer ball), it would make sense to me that they would have superior skill sets in processing the fast-paced information to successfully cross the street.”
