12.HAVE you ever gotten a song kept in your head?You sing it all the time-on your way to school,before sleep,even when you're sitting on the toilet.You want to forget it,but the music just keeps sounding in your head.
Some people call these annoying songs"earworms"because they are just like parasites(寄生蟲)-they"live"in your ears and refuse to leave even when you tell them to.
But why do some songs become earworms and not others?According to Ira Hyman,a music psychologist at Western Washington University,people are more likely to remember songs that are simple and repetitive,especially ones with that type of music."Choruses tend to get stuck in your head because they are the bit we know best,"Hyman told The Tele-graph.
If you've got an earworm,you can suffer an attack without even hearing it.Seeing words from the song or hearing someone mention it could both cause the domino effect that starts the song running.
Scientists have been trying to find a solution to deal with earworms.They say the best way is to fill your mind with something else.But here is the tricky part:the task you do should be neither too hard nor too easy.The harder you try not to think about the music,the more you won't be able to help it.On the contrary,a task like jogging which is too easy won't keep your brain busy enough,and that could allow the song to come back.
"The key is to find something that will give the right level of challenge."said Hymen.Reading a difficult book or a good novel could count.
