Jessica uses behavioral and neuroimaging methods to study the origins of quantitative reasoning in human adults, children, and non-human primates. Her research shows the impact of early-developing and evolutionarily primitive nonverbal concepts on human thought. Using behavioral methods, her work observed parallel numerical processing capabilities between human children and non-human primates. Using fMRI, she found that the IPS processes quantitative information in children as young as 4 years of age. Her research implicates a primitive cognitive and neural basis for the development of human mathematical cognition derived from very old, evolutionary processes.
