Ian Lyons
Background
Ian received a Bachelor of Science degree from Brown University where he worked on models of human causal reasoning. He later worked as a research associate at Dartmouth College obtaining and analyzing neuroimaging data regarding the neural substrates of numerical cognition. Ian began his PhD at the University of Chicago in September of 2006.
Research Interests
Ian is interested in understanding the neural and cognitive mechanisms underlying mathematical thinking. On the one hand he is interested in 'lower-level' perceptual and attentional processes responsible for the extraction and representation of basic numerical concepts, such as symbolic association and quantity representation. On the other hand, he is working to understand how numerically related processes interact with 'higher-level' functions such as working memory to produce more complex mathematical skills and behaviors. He believes both of these lines of research are important for understanding how social and developmental factors affect the fundamental and complex human ability to create and manipulate mathematical concepts.
