There must be some songs that just become rooted in your brain--- "Call Me Maybe," "Poker Face" and "Let It Go," to name a few. But do you know why these sticky songs --- ear worms, as our brains? they're known --are so hard to get rid of? And what kinds of songs are【小题1】to become sticky in our brains.

A few studies hold at least some answers. First of all, common ear worms seem to share some exhausted features. They're songs| you've heard a lot (which may be why current radio 【小题2】tend to dominate “Top 10 Ear worm"list). They often have repetitive notes or unexpected intervals (间隔) in timing. They also have 【小题3】rhythms and pitch (高音) patterns.

Scientists sometimes【小题4】to ear worms as "involuntary musical imagery". A study found that about 90 percent of Internet users reported getting a song【小题5】in their head at least once a week. The more musical the person is, the more ear worms they were likely to experience, the study found, and that result has been 【小题6】 up by other surveys. Research【小题7】at the 12^th International Conference on Music Perception and Cognition in 2012 in Greece found that longer no with smaller intervals of pitch between them made for stickier ear worms. It is【小题8】because long notes and limited changes in pitch are simply easier to sing. The research' also found that people with obsessive-compulsive (强迫症的)traits (meaning they have a【小题9】toward worry) reported ear worms more frequently.

People are more likely to pick up an ear worm when they are doing something【小题10】, like jogging or chores (家务活), according to another study.

Jill has a talent for music, but when she was 20 years old, a serious disease made her ache all over. From then on, she went through many 【小题1】, but none could 【小题2】the disease. In 【小题3】, she lost the opportunity to get onto the stage with her band. The disease also had an【小题4】on her appearance. She tried out for some shows, but the reaction from audience was terrible, though she was a capable composer and a good performer.Gradually, she became 【小题5】in watching her previous albums,【小题6】that she was still fine. Worried about the phenomenon, her parents tried to help her out somehow. One day they sent one of her original compositions to a virtual choir. The conductor in charge fell in love with the energy in her music. Instead of telling a romantic story, her music can touch people’s soul, bring people 【小题7】and give a sense of satisfaction. Nowadays they have designed a special studio for her with various【小题8】. This enables her to 【小题9】her talents and to win an award.

Unfamiliar Music May Help People Chat at Parties

If you want your guests to be particularly sociable at an upcoming party, make sure you play music they probably haven’t heard before.

To explore how background music affects the way we 【小题1】 conversations, researchers Jane Brown and Gavin Bidelman conducted a study analyzing the brain activity of 31 individuals aged21 and 33. During the experiment, participants listened to 72 minutes of an audiobook (有声读物), which the pair used as a replacement for 【小题2】 on someone talking, while background music was accompanied by the audiobook for most of the time.

For half of the experiment, the participants were asked to focus on2-minute parts of an unfamiliar audiobook read by a man. The rest of the time, they were told to focus on four background songs, which were similarly 【小题3】 for2 minutes at a time. This 【小题4】 in voices aimed to assess participants’ ability to shift attention between two distinctly different voices.

During the experiment, all the participants wore 【小题5】 caps to monitor the electrical activity taking place in their brains. This 【小题6】 of electrical activity was the key. It allowed Brown and Bidelman to discover how efficiently these individuals could focus on either the audiobook or the music when 【小题7】 to do so. The finding revealed that the participants could 【小题8】 turn their attention to the audiobook if the background music was unfamiliar to them.

Following the task, the participants completed a music perception survey evaluating their musical skills, such as the capacity to 【小题9】 whether a pair of similar-sounding tunes are the same. Notably, those with lower musical scores demonstrated slower attentional shifts between songs and audiobooks, suggesting a(n) 【小题10】 link between musical ability and attention management skills.
