Research Interests

I am interested in the origins and development of nonverbal representations of quantity. I investigate the extents and limits of two mechanisms proposed to underlie human and nonhuman animals’ nonverbal quantity representations – the analog magnitude system, AMS, and the object tracking system, OTS. In particular, I examine (a) how the systems are engaged in different contexts, (b) how precise the resulting representations are across development, and (c) what computations can be performed over the representations.
