Chris Cox

Hello! I’m Chris Cox, currently a fifth year graduate student at the University of Wisconsin, Madison. In collaboration with the Knowledge and Concepts and Language and Cognitive Neuroscience Labs, I am working with Tim Rogers and Mark Seidenberg to investigate how the meanings of words are represented in the brain.

Distributed representations

Much of my work directly confronts the possibility that the brain represents meaning in idiosyncratic patterns of activity distributed throughout the brain. This is based on two basic hypotheses: (1) that meaning is not static, and not universal, and will be completely experience and context dependent, and (2) that meaning is supported by much of the brain.
