Converging evidence has shown that domain-general cognitive abilities, especially executive functions (EF), tend to be superior in sport experts. However, recent studies have questioned this cognitive advantage and found inconsistent findings when comparing sport type and sex. This study aimed to compare the impact of sport expertise, sport type, and sex on various domains of cognitive functions.Two hundred and thirty elite athletes (nFemale = 124, nMale = 106) representing three sport categories (Team [n = 91], Precision-skill dependent [n = 63], and Speed-strength [n = 76] sports) were assessed using a computerized neuropsychological test battery including tests of EF (working memory, inhibition, cognitive flexibility and planning), as well as tests of selective and sustained attention. T-scores and raw values were used to analyze performance through t-tests and ANCOVA with age as covariate.Athletes demonstrated better performance than the normative mean on 5 out of 11 cognitive test variables (p < 0.005). However, their performance fell within the average range when considering the results along a normative scale, except for sustained attention and working memory where they performed just above average (<1 SD). There was a significant main effect of sport category on only one EF variable (p = 0.003). Males performed significantly faster than females on motor reaction time measures of attention and inhibition (all p < 0.001).In this study, the ‘expert advantage’ on domain-general cognitive tests was less prominent when utilizing a normative scale and controlling for age or speed-accuracy trade-offs, except for sustained attention and working-memory. Cognitive functions did not appear to differ meaningfully based on athletes’ sport type or sex.
