Professor Troseth's research focuses on young children's symbolic development, including their understanding of representational artifacts and media (e.g., pictures, video images, touchscreens, scale models) and of the intent to symbolize. Current research involves designing an intelligent (AI) character in an eBook to support parents' use of "dialogic questioning" while reading picture books with their children.
At Vanderbilt University, Troseth teaches graduate and undergraduate courses in developmental psychology, cognitive development, representation and symbols. and a first-year writing seminar on Harry Potter and Child Development.
