Plop ! Ou peu s'en faut :
Although improvements were observed in every one of the cognitive tasks that were trained, no evidence was found for transfer effects to untrained tasks, even when those tasks were cognitively closely related.

we find extensive evidence that brain-training interventions improve performance on the trained tasks, less evidence that such interventions improve performance on closely related tasks, and little evidence that training enhances performance on distantly related tasks or that training improves everyday cognitive performance

A contrario, la pratique du jeu d'échecs a des effets bénéfiques bien réels sur certaines aptitudes cognitives :

Quelle cause faut-il comprendre de cette différence d'efficacité entre des exercices spécifiques et des pratiques plus "larges" ayant l'entraînement cognitif comme effet plutôt que comme but ?
