Research Interests: Development and Evolution of Numerical Abilities

Current projects: Number and time discrimination in infants, Electrophysiological correlates of timing and counting in human infants, Psychophysics of numerical discrimination in monkeys and lemurs, Electrophysiology of number representation in monkeys, Neural correlates of number in adults and children, using fMRI

Dr. Brannon's research program examines the evolution and development of quantitative cognition. She studies how number, time, and spatial extent are represented by adult humans, infants, young children and nonhuman animals without language. With her many collaborators at Duke she applies behavioral techniques, event-related potentials, functional magnetic resonance imaging, and single-unit physiology to explore the cognitive and neural underpinnings of numerical cognition in nonhuman primates and throughout the human lifespan.
