为什么有些歌总在脑子里不停“播放”？因为它们简单且易于重复？因为它们很烦人？还是因为它们是为人熟知的老歌？最新研究发现，只有你真正了解并且喜欢的歌才最有可能在你脑海里不断重复。该研究小组还探索了记忆线索在这方面起的作用，探索了新歌在初次听到后24小时内成为“自动播放曲”的可能性，以及这种现象与思想走神的联系。研究结果显示，从事刺激性活动使大脑出现超负荷，会增加这些歌曲出现的频率。这一研究对于理解侵入性思想是很有价值的。
Can’t Get you Out of My Head: How to Control the Song Stuck in Your Mind
Why do some songs get stuck in our heads? Is it their simplicity and repetitiveness, because they’re annoying, or because they’re an old favorite? New research into ‘earworms’ has found that contrary to belief, it is songs which people know and like which are most likely to become mentally struck on repeat. The team also explored the role of memory cues in the environment, the likelihood of a new song becoming an earworm within 24 hours of first hearing it, and the connection to mind wandering. The results show that overloading the brain with challenging activities can increase the frequency of earworms, a discovery which may prove valuable to understanding intrusive thoughts.
