Learning multiple languages in children would make them more flexible brain, according to a Canadian study. Indeed, their ability to change their language would solve problems more easily and they would benefit from a better memory.
The research, conducted by scientists at Concordia University (Canada) and published in the Journal of Experimental Child Psychology, was conducted among 39 small bilingual volunteers and 43 other monolingual children at age 24 months, and 31 months.
The researchers looked at first to the vocabulary of participants. Scientists were then perform tasks for children to analyze their cognitive flexibility and storage capacity.
Alternate languages helps to alternate tasks
Results: bilingual children had a rich vocabulaireplus that monolingual. Also, participants who spoke several languages had more facilities to follow conflicting instructions for performing certain tasks (putting small blocks in a little basket and large blocks in a big basket. Then, vice versa).
For scientists, this performance observed in polyglot seems to be attributable to greater cognitive flexibility and improved selective attention capacities related to their experience of alternation between languages and words.
In 2013, researchers had already discovered that bilingual adults since childhood had better cognitive flexibility. In 2014, another research showed that bilingual children showed more attention and were cognitively more advantaged.
