Brain training breakthrough: motor skills may unlock language learning
NCT ID NCT03223090
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores whether training your motor skills (like hand movements) can also improve your ability to learn a language. Researchers believe that when the brain changes to learn a new physical skill, it might also boost nearby brain areas used for language. The study will involve 1,111 healthy French-speaking adults aged 20 to 40, and will measure language performance before and after motor training.

Inclusion Criteria: * Be aged between 20 and 40 years old * Give an informed consent by signature * Be part of the national health security system (registered to the Securité Sociale) * Be French speaker Exclusion Criteria: * A person presenting an history of neurological, psychiatric or linguistic problems cannot be admitted * Assumption of psychotropic drugs * Pregnancy or breast-feeding woman * A person under legal tutoring * A person under care in other medical structure for reasons different from those of this research * A person under administrative or judiciary contention * A person who is not eligible to a MR-exam according to the relative screening questionnaire cannot be admitted to the experiments including MR acquisitions in the protocol * A person who is not eligible to a tDC Stimulation according to the relative screening questionnaire cannot be admitted to the experiment including tDCS in the protocol * A person who is defined as bilingual according to the criteria described above cannot be included in this research. * A person who studied a musical instrument for more than 3 years or plays it regularly cannot take part to the studies in Objective B1, B2 and B3. This might introduce a confound in the rate of motor learning and relative brain plasticity. * A person who has already learned or has been regularly exposed to the language L2 and/or to the sign language chosen for the studies in Objective A1 and A2 cannot take part to those studies.
