Dr. Ashby is interested in basic cognitive and neural processes of human learning and memory. As a vehicle for studying these processes, his research focuses on understanding how people categorize objects in their environment. Dr. Ashby’s approach is to collect a wide variety of empirical data (e.g., from cognitive behavioral experiments, studies with various neuroexperiments, studies wpsychological patient groups, and fMRI experiments), and use these data to develop and test neuro-biologically detailedmathematical models. Thus, Dr. Ashby's research combines a three-pronged approach: empirical data collection, cognitive neuro-science, and mathematical modeling.
