Their research again points to superior cognitive skills in children -- this time in the mathematical realm. However, their research only targeted a small sample of children from the same cultural background. I would like to extend to a cross-cultural sample from actual different countries. If my research supports that of Levine and Huttenlocher, as I predict it to be ramifications include the fact that differences in mathematical ability are likely initiated due to other factors (such as school, teacher, parents) and are not innate. As Levine and Huttenlocher's research shows, abstract mathematical skills emerge as early as 3; verbal mathematical skills emerge later. Differences in mathematical ability (and, by extension, differences in other intellectual abilities) may be a consequence of other factors rather than intrinsic.
