Abstract
This is a poster that we presented at the virtual Eastern Psychological Association Conference in March 2021. The ability to enumerate is foundational for the development of mathematics skills. Using ERP and behavioral measures, this study investigated neural characteristics of exact enumeration of small quantities, compared to a similar but non-numerical task. An N400 component, associated with recruitment of semantic knowledge, was observed during the enumeration task but not the non-numerical task. Further, N400 amplitude increased with quantity. Findings provide preliminary evidence that adults recruit number knowledge even when enumerating small quantities.
