Have you ever had a song playing in your mind that you just can’t tune out? The social science term for this is “involuntary musical imagery” (IMI) otherwise known as an “earworm.” In this post, I’ll discuss research about IMI, focusing on data from a study by Victoria Williamson and colleagues tracing the “earworm” phenomenon. I end by discussing some gaps in the research, and I reflect on my experiences with earworms.
Much of our thinking happens without our conscious attention. Involuntary thoughts are always running in the back of our brains. These unconscious thoughts happen spontaneously, but they reflect our prior experiences. So why do earworms exist? It turns out that they serve both a functional and a socio-psychological purpose.
