Barbara Sarnecka

I am interested in how the mind is put together. I am especially interested in where concepts come from, and most of my work looks at how young children acquire number concepts. Relatedly, I am interested in how early childhood education can support young children's understanding of numbers and lay the foundation for later learning in science, technology engineering and mathematics (STEM). I am also interested in language development, particularly in the role that language plays in conceptual change. I feel lucky to live and work in Southern California, which has an exceptionally diverse population and allows me to include children from many different income and language backgrounds in my research. Finally, I believe in open science. I try to use my own work as an author, reviewer and editor to support noncommercial, open-access publishers whenever possible.
