Gut Instinct’s Surprising Role in Math


Inside of each of us is an innate ability to quickly decipher numerical differences between groups  – the number of people waiting in checkout line 1 vs. checkout line 2 – and use this information to our advantage (e.g. picking the shorter line). Researchers from Johns Hopkins University and the Kennedy Krieger Institute have discovered a link between this primal “approximate number” sense and the degree to which individuals are skilled at higher-level, abstract math skills.

In a study of 14 year-olds, the researchers found that the ability to quickly identify differences in the number of colored dots on a slide was positively correlated with the teenager’s ability on a range of standardized math tests – going all the way back to Kindergarten. In other words, if you can quickly decide if there are more yellow or blue dots on a slide, you are more likely to be strong in math.

The study, however, raises a number of important questions: does one's approximate number sense change as you develop from an infant to young adult? Can it be improved with training (quantity of training or quality of training)? From a brain "wiring" perspective, how does the approximate number sense interact with the abstract, higher-level math sense? Does the correlation hold for a larger sample of teenagers, from different cultures and different parts of the globe? The answers to these questions may eventually shape how early math courses are taught.

Interesting study! I suspect the answer lies somewhere in-between. Like parts of our personality and behaviour are in-born and some are learnt.

In any case, I think overall this is study is an argument to support young kids to develop a good and strong foundation in math.
