The research, carried out at University College London’s Institute of Cognitive Neuroscience, tested the idea of time dilation prior to motor action using a series of tests. Dr Nobuhiro Hagura, one of the researchers, explains to the BBC:
“John McEnroe has reported that he feels time slows down as he is about to hit the ball, and F1 drivers report something very similar when overtaking. Our guess is that during the motor preparation, visual information processing in the brain is enhanced. So, maybe, the amount of information coming in is increased. That makes time be perceived longer and slower.”
