Melissa E Libertus, Graduate Student    Edit

Research Summary:
In my dissertation research, I investigate the way in which numerical information is represented and processed in the human mind and how it changes over the course of development. To this end, I use behavioral and neuroimaging techniques to test the early and mature number sense in human adults, children, and infants. I am also interested in the relationship between individual differences in numerical cognition and other cognitive domains.
