"I'm Michelle Hurst, a postdoctoral scholar at the University of Chicago. In my current research, I am interested in how people reason about quantitative information and the relations among this information. In this study, I am investigating the development of relational reasoning and how it might vary across different relations (e.g., physical size versus numerical size), different representations (e.g., symbolic "4" vs. four items), and different levels of relational reasoning (i.e., which of two sets has more vs. which of two sets has a higher proportion)."
