What is it about?
Number systems differ cross-culturally in characteristics like how high counting extends and which number is used as a productive base. Some of this variability can be linked to the way the hand is used in counting. The linkage shows that devices like the hand used as external representations of number have the potential to influence numerical structure and organization, as well as aspects of numerical language. These matters suggest that cross-cultural variability may be, at least in part, a matter of whether devices are used in counting, which ones are used, and how they are used.

Perspectives
I am interested in how societies become numerate by using and recruiting material forms into the cognitive system for numbers over generations of collaborative effort. The manuovisually engaged domain of material forms is a primary mechanism for realizing and elaborating numerical concepts. I also look at the effect this elaborational mechanism has on conceptual content, and what this might augur about the future of human cognition.
