Mark’s research focuses on the evolution of morality.

Aaron Chuey
Aaron is the lab manager at the Cognition and Development Lab. He is broadly interested in the way we carve up the world. In particular: Where do children’s intuitions about the ways objects and creatures work originate? How do these intuitions change across development? In what ways are these intuitions sophisticated and in what ways are they lacking? How can we remedy the large gaps in our intuitions and better teach mechanistic information to children and adults?
