As regular readers know I am a music lover with a wide range of tastes. One of my favorite aspects of bike riding is the bluetooth speaker on my water bottle that lets me listen to the tunes on my iPhone as I pedal along. When my daughter, now 23 years old, was a toddler, I remember watching music videos with her and enjoying – The wheels on the bus go round and round … – too many times to count. That and numerous other tunes provided a regular source of engagement and enjoyment for her. At the time it just seemed like a fun thing to share with her. But, it seems she was getting a lot more out of it than I knew, according to a study presented at the Cognitive Neuroscience Society (CNS) meeting in Boston.
A universal sign of motherhood is the lullaby. The world over, mothers sing to their babies, whether Twinkle Twinkle Little Star, their favorite song from the radio, or even random notes. This universality makes the simple lullaby a great window into the human mind. In a new study, cognitive neuroscientists found that lullabies soothe both moms and babies simultaneously, while play songs increase babies’ attention and displays of positive emotion toward their mothers.
The behavioral implications of music are vast, says Laura Cirelli of the University of Toronto Mississauga, who presented the new work on maternal singing at the 25th meeting of the Cognitive Neuroscience Society. “Infant brains must be able to track auditory events in a predictive manner to make sense of music,” she explains, and many complex things are going on in their brains to make that possible.
