Research Interests: Development and Evolution of Numerical Abilities
The main focus of my research is how human adults, infants, and monkeys represent number. Numerical thinking allows a comparison of animal and adult human cognition because it involves abstract representations that do not rely on language and appear to be specialized and modularized. Equally important is understanding how numerical representations develop in the human lifespan and how language transorms these representations. My broad research goal is to determine the similarities and differences in the cognitive processes that human adults, human infants, and animals use in numerical thought and to explore the brain systems that support thinking about number. - Keywords:
