My lab relies upon a broad-based and interdisciplinary cognitive neuroscience approach to address questions that fall within two predominant strands of research. One strand is focused on the neural basis of language processing. Topics of interest include the articulatory and phonological codes involved in verbal working memory, and the ways in which different writing systems influence the representation and processing of orthographic information. A second strand is focused on basic learning systems in the human brain. We are especially interested in how cognition may be optimized by reinforcement learning signals mediated by the basal ganglia and error-correction signals mediated by the cerebellum.

Julie Fiez is a Co-Director of the Behavioral Brain (B2) Research Training Program along with Lori Holt of Carnegie Mellon University. B2 has been renewed for five more years of funding by the National Institutes of Health. This program aims to train the next generation of behavioral science researchers who can skillfully incorporate neuroscience perspectives and methods into their programs of research, based on an understanding of brain structure and function that bridges traditional areas of behavioral research.
