Social Cognitive Neuroscience

The primary focus of our research is social cognitive neuroscience: understanding how the brain allows people to make sense of each other. To that end we use functional magnetic resonance imaging (fMRI) to examine the neural basis of diverse social phenomena. To learn more about our research, see the list of recent publications below or check out our lab website.

The Mind on the Web

We use large scale web research to complement the fine-grained work we do with fMRI. MySocialBrain.org is a platform for wide variety of social cognitive experiments. It allows us to study much larger and more diverse groups of people than we would otherwise be able to. From the participants' point of view, it offers engaging, interactive experiments with personalized feedback to a broad audience.

Individual differences in social abilities

One of the major goals of this site has less to do with any one study than with the correlations of multiple studies. Research on "individual differences" - the psychological properties that make people different from one another, such as personality or intelligence - requires very large sample sizes for meaningful results. That's where our account system comes in. By registering, you allow us to correlate your (de-identified) data across studies, and thereby answer exciting new questions.

Our Team

Principal Investigator | Mark A. Thornton, Ph.D.

Mark studies the structure of social knowledge - how we organize and make sense of other people's mental states, traits, relationships, groups, and networks. He is particularly interested in how the brain implements accurate, efficient solutions to challenging problems in the social domain. Mark received his A.B. from Princeton University in 2011 and his M.A. from Harvard University in 2013. He received his Ph.D. in Psychology from Harvard University in 2017. He then returned to Princeton to conduct postdoctoral research. Mark is currently an Assistant Professor in the Department of Psychological and Brain Sciences at Dartmouth College, where he directs the Social Computation Representation And Prediction Laboratory.
