I am interested in the origins of human concepts,
both in terms of how concepts have evolved over millions of years and in terms of how human concepts develop over an individual
lifespan. My research domains include numerical cognition, magnitude estimation, the alphabet, and everyday concepts such as 'face'
and 'shoe'. I use fMRI and behavioral measures to study the cognitive and brain mechanisms involved in conceptual processing in
pre-school children, non-human primates, and human adults. Using this comparative approach, we can identify both the shared and
unique brain functions underlying conceptual knowledge across species and stages of development—with the goal of understanding
the structure of the human mind.
I study the cognitive and neural processes that make
possible very simple things that we do on a daily basis. Imagine there is a glass of water on the table. One may look at the glass
and name it as 'a glass of water'; or, one may simply pick up the glass and take a drink. My research addresses the processes
involved in categorization and recognition of the visual input, the engagement of motor knowledge necessary to manipulate objects,
and the dynamics of information retrieval within the speech production system. The goal of this research program is to merge insights
from studies of neuropsychological patients with functional imaging studies of the healthy brain in order to articulate a model of
object use and object naming.
