ab: Summary: Individual differences in inhibitory control have been shown to
relate to general mathematics achievement, but whether this relation
varies for specific areas within mathematics is a question that remains
open. Here, we evaluate if inhibitory processes play a specific role in
the particular case of fraction comparison, where learners must ignore
the potentially misleading information provided by the natural numbers
composing fractions (e.g. $2/3>4/7$ despite $2<4$ and $3<7$). To do
this, we presented a sample of Chilean children ($N=450$) from 5th,
6th, and 7th grade with a numerical comparison task tapping inhibitory
and other processes. Results showed that both general math achievement
and accuracy in comparing fractions were significantly predicted by
inhibition. The former association, however, turned out to mediate the
latter one. Another process, related to visual priming, predicted
children’s likelihood to answer fraction comparison items focusing
exclusively on the fraction components. This relation was, furthermore,
not mediated by general math achievement. Altogether, these findings
shed light on the mental processes underlying the early stages of the
learning of fractions.
