Does it seem like music slows down when you yawn? Music sounds like it slows down when we yawn due to "Chronostasis." HAVE you ever yawned while listening to music through headphones and thought the music slowed down? Apparently this is due to something called chronostasis. Chronostasis is what happens whenever a shift in your attention causes the bran to draw out a moment, leaving you with the feeling that something is happening slower than what it is. This theory was believed to be the reason why it appears the second hand of the clock freezes when you quickly look at a clockface, so a team decided to experiment if it was the reason behind music slowing down, too. Science site, iO9 found the experiment which involved a bunch of volunteers who were asked to put on headphones and listen to see if they heard a tone in just one ear at a time or both. If they heard the tone in one ear before the other, their brain misjudged the length of time and the experience was drawn out longer than what it actually was. Just like with the clock hand, it was a shift in attention that stretched the time. When you yawn, you hear a rush in your ears, so listening to that and then the music draws out the music until the song sounds too slow. Try it next time you're in the car!
