Twenty-two years ago to the day, on January 30, 1994, Peter Leko became the world’s youngest chess grandmaster, at the age of 14.
A proficiency in chess is often linked with higher intelligence, that is, the more intelligent you are, the more likely to be good at chess. This assumption has roots probably in the observation that chess does not allow for random chance or physical attributes, as most games do. So it follows that of you are good at it, it must be… intelligence, although there are at least an equal number of studies if not more that show that practice has more an impact on your chess ability that your native IQ score.
Personally, as one that always looks askance whenever there is talk about intelligence quotient and intelligence tests, I have serious doubts that any of these papers measured what they claimed they measured. And that is because I find the construct “intelligence” poorly defined and, as a direct consequence, hard to measure.
That being said, Sala et al. (2015) wanted to see if chess practice can enhance mathematical problem-solving abilities in young students. The authors divided 560 pupils (8 to 11 years old) into two groups: one group received chess training for 10-15 hours (1 or 2 hours per week) and an option to use a chess program, while the other group did not participate in any chess activities. The experiment took 3 months.
Both groups were tested before and after training with a mathematical problem-solving test battery and a chess ability test.
“Results show a strong correlation between chess and math scores, and a higher improvement in math in the experimental group compared with the control group. These results foster the hypothesis that even a short-time practice of chess in children can be a useful tool to enhance their mathematical abilities.” (Sala et al. (2015, Abstract).
This is all nice and well, were it not for the fact that their experimental group had significantly more pupils that already knew how to play chess (193 out of 309, 62%) compared to the control group (72 out of 251, 29%). To give credit to the authors, they acknowledge this limitation of the study, but, surprisingly, they do not run their stats without the “I-already-know-chess” subjects….
Nevertheless, even if the robustness and the arguments are a little on the shoddy side, the paper points to a possible fruitful line of research: that of additional tools to improve school performance by incorporating game and playtime into the instructors’ and parents’ teaching arsenal.
