Highlights
•
Gf, Gc, Gsm, and Gs all correlated positively and significantly with chess skill.
•
The relationship between Gf and chess skill was moderated by age and skill level.
•
Chess skill correlated positively with numerical, visuospatial, and verbal ability.
Abstract
Why are some people more skilled in complex domains than other people? Here, we conducted a meta-analysis to evaluate the relationship between cognitive ability and skill in chess. Chess skill correlated positively and significantly with fluid reasoning (Gf) ( = 0.24), comprehension-knowledge (Gc) ( = 0.22), short-term memory (Gsm) ( = 0.25), and processing speed (Gs) ( = 0.24); the meta-analytic average of the correlations was ( = 0.24). Moreover, the correlation between Gf and chess skill was moderated by age ( = 0.32 for youth samples vs. = 0.11 for adult samples), and skill level ( = 0.32 for unranked samples vs. = 0.14 for ranked samples). Interestingly, chess skill correlated more strongly with numerical ability ( = 0.35) than with verbal ability ( = 0.19) or visuospatial ability ( = 0.13). The results suggest that cognitive ability contributes meaningfully to individual differences in chess skill, particularly in young chess players and/or at lower levels of skill.
