Hi, I’m Sam. I direct The Music Lab, a research group at Harvard University focusing on the psychology of music. Our work draws on ideas and tools from cognitive, social, and developmental psychology, data science, and evolutionary anthropology, to ask what music is, how music works, and why music exists.
For example, in the Natural History of Song project, we investigate the perceptual and cultural building blocks of music worldwide, to lay out basic facts of our psychological capacities for music. We build music corpora and use them in citizen-science experiments to ask how people hear music and what people understand about music, even when it was produced in cultures or languages unfamiliar to listeners. We’re also interested in how music listening affects emotions and health in the daily lives of infants, children, and parents; and how musical abilities vary across different people and different societies, including rare musical impairments like congenital amusia (tone-deafness).
Since the lab’s inception, we have run experiments with over 4 million people via our citizen-science platform. You can participate at themusiclab.org.
All of our papers and preprints are available below. For a lighter introduction to our research, here are some links:
Lab alumnae Connie Bainbridge and Mila Bertolo discuss the relaxing effects of lullabies on infants on The Science of Happiness podcast (paper in Nature Human Behaviour).
Paula Span wrote a lovely New York Times piece about music in infancy, drawing in part on our papers in Psychological Science and Developmental Science. More recently, I discussed those findings on A Life in Music, a BBC Radio 4 special.
For an accessible summary of research on the idea that “music makes you smarter”, check out this Times op-ed.
A bit about me: I began my career at the Eastman School of Music, where I studied music education and got my first experience working with infants, children, and their families. In my last semester, I took a wonderful course in cognitive development with Elissa Newport and Richard Aslin, which led to a research assistantship at Harvard with Liz Spelke. I stuck around for grad school, working with Liz, Howard Gardner, Max Krasnow, and Steve Pinker. After finishing my doctorate I was lucky enough to start a lab at Harvard with funding from the NIH Director’s Early Independence Award and the Harvard Data Science Initiative.
If you’re interested in joining us, please see our open positions. You should also feel free to contact me directly, even if we don’t have a position posted. I’m always interested in hearing from new students!
