Our ability to perceive rapid changes in visual scenes over time – our “speed of sight” – varies a surprising amount between people, according to the first study to systematically investigate the question.

This suggests that some people can track fast-moving objects better than others because of their innate superior vision, which may contribute to people’s different abilities in sports like baseball and cricket, says Clinton Haarlem at Trinity College Dublin.
