Ear Worms

THE FACTS
Virtually everyone experiences them, and rarely are they thought of fondly. They are earworms, the tunes that burrow into our consciousness and play on repeat.

In a recent study involving hundreds of people, Ira Hyman Jr. of Western Washington University and colleagues looked at what made songs most likely to stick, exposing unsuspecting subjects to popular songs and then asking them to complete various tasks.

Previous research showed that people can recall the first verse of a song they like, but after the chorus stumble over the lyrics. At this point the song becomes incomplete — a conflict without closure — and that is one way that it becomes an intrusive thought, Dr. Hyman said.

“You get to the chorus, and then it’s looping right there, and you’re kind of doomed at that point,” he said.

The study found that songs typically intrude during tasks that are either too difficult, which causes the mind to wander, or too easy, which creates a mental opening for repetitive thoughts. The trick to flushing out an earworm, Dr. Hyman said, is to find a task that is engaging and that requires the auditory and verbal components of your working memory — like reading a good book or watching a favorite show.

THE BOTTOM LINE

Research suggests that songs we like, not ones we despise, are most likely to form intrusive thoughts.
