The field of cognitive development seeks answers to fundamental questions in cognitive science: What do we know? How do we know it? And, importantly, how do we learn about it? The goal of this course is to give you a broad overview of the theories, methods, and findings related to the origins cognition in childhood. At the graduate level, this course emphasizes foundational texts but also a critical evaluation of emerging areas of research. This course is also an opportunity for junior scholars to develop original research ideas that address open questions of interest at the intersection of cognitive development and their own emerging program of research.
