Barbara W. Sarnecka
Much of my work over the past 20 years has been about how young children acquire number concepts. But in recent years, I've branched out to work on social cognitive development, the development of judgment and decision making, adult moral psychology, and most recently, scientific writing. (Developing and testing ways to help PhD students and other scientists increase their productivity and write more clearly.)
I believe in open science. So we make the research process in our lab as transparent as possible, and we make all of our scientific outputs (papers, data, code, etc.) immediately and freely available to everyone. If you are a prospective graduate student, I am generally open to accepting new students into the lab every year. You should apply to the PhD program in Cognitive Sciences and when you are invited for an interview, request to meet with me.
