Scholarly Interests: Infant, child, and adult cognition. Preverbal and verbal representations of number, space, and time. Children's early counting acquisition and understanding of mathematical concepts. Music cognition and perception. Psychophysics of quantity perception. Learning throughout the lifespan. Influences of language and context on learning, discrimination, and decision-making.
Academic Profile: Sara Cordes' research is centered upon understanding how it is that infants, children, and adults keep track of quantity - that is, how they attend to, represent, and process number, time, and amount (e.g. volume, surface area). This research is based upon the assumptions that humans, throughout the life-span, as well as non-human animals, learn about the world through tracking these quantities in their environment and that these representations of quantity also serve as the basis for later, verbal and symbolic representations of number (e.g., verbal counting). Research questions revolve around understanding exactly how infant representations of number and other quantities map to later mathematics competence and factors that may contribute to increased precision in representing quantity. In addition, other research investigates how numerical competence and fluency in early childhood affect decision making in probabilistic (gambling) tasks.
