The video discusses the phenomenon of "earworms," or songs that get stuck in our heads, often unexpectedly. Over 90% of people experience earworms, especially during repetitive tasks like waiting for water to boil.
The cause of earworms is still unclear, but they are a form of auditory imagery that can intrude on our mental space involuntarily. Earworms are often vivid and loop repeatedly, usually consisting of short fragments of tunes rather than full songs.
Repetition plays a significant role in triggering earworms, with modern technology (like streaming and CDs) making it easier to listen to songs repeatedly. Although earworms seem to be exacerbated by modern devices, they are not a new phenomenon, as historical figures like Mark Twain mentioned them long before the invention of recording technology. The reason music, and not other sensory experiences like taste or sight, is prone to becoming an earworm might lie in how we process and remember tunes.
Once a song starts, we naturally anticipate the next note, making it hard to stop the mental repetition. Despite speculation, scientists still don’t know the exact cause of earworms, but understanding them could provide insights into brain function.
