Exploring relations between approximate number system acuity, eye movements, and math ability
Many decisions are guided by our basic intuitions of quantity, which is supported by the Approximate Number System (ANS). Individual differences in a dot comparison task used to index the ANS may reflect differences in the acuity of underlying number representations and are often linked to formal math ability. Moreover, this variation may reflect differences in the cognitive processes that are involved in ANS tasks, which can be approximated by the eye movement or tracking strategies that people employ during these assessments. The present study examined relations between adults’ ANS precision, the frequency with which individuals switched between dot arrays via eye movements in an ANS task, and math ability. Linear regression analyses revealed that ANS acuity was related to switching frequency and this relation was stronger for those with higher math ability. This study adds to an emerging body of work in numerical cognition which has implications for decision-making.
