Turns out, your favourite tunes might outlast your ability to remember where you left your keys. A new study from the University of Lincoln, led by Sarah Sauvé, suggests that our musical memory stays sharp even as other cognitive functions fade with age. Published in PLOS ONE, the research highlights that familiar music can be remembered and recognized regardless of age, offering a potential lifeline for those with neurodegenerative diseases like Alzheimer’s.
How the Study Worked
The study explored how familiarity and aging affect our ability to recognize and retain musical memories. Participants, ranging in age from 18 to 86, were exposed to live and recorded performances of three musical pieces: Mozart’s Eine Kleine Nachtmusik and two specially commissioned compositions — one tonal, one atonal. They were tasked with identifying these themes as they were played, whether they experienced the music live at a performance by the Newfoundland Symphony Orchestra or in a lab setting.
Key Results
Interestingly, the results showed that recognition was most accurate for the familiar Mozart piece, followed by the new tonal piece, with the unfamiliar atonal piece scoring the lowest. What’s fascinating is that age and prior musical training didn’t significantly affect the participants’ ability to recognize the music. Instead, familiarity was the key factor. This suggests that while our ability to learn new information may decline with age, our capacity to recall familiar, well-established memories remains robust.
The Science Behind It
Cognitive neuroscientist Steffen Herff of the University of Sydney, who commented on the study, pointed out that emotional connections to music could play a significant role in this resilience. The emotional processing center of the brain, the amygdala, might act as an “importance stamp,” helping to secure these musical memories against the effects of time.
Why is it Important?
The study offers a better glimpse into how memory operates, and in practical terms, a possible tool for therapists. As the paper’s author Sarah Sauvé noted, there is already anecdotal evidence that musical memory can withstand the harmful effects of neurodegenerative disease. The study offers more proof. If music is largely immune to the effects of cognitive decline, it could be used as a therapeutic tool to help people with conditions such as dementia which impairs memory.
