Beim gemeinsamen Spielen synchronisieren sich die Gehirnströme von Müttern und Kindern – auch in einer erworbenen Sprache

> Neural synchrony between socially interacting people is known to boost social and emotional connection and communication. Researchers have now shown that mothers who speak English as a second language during play with their bilingual toddlers aren’t less effective at achieving this desired ‘attuning’ of their brains. These results suggest that optimal learning and mother-child bonding don’t require native proficiency.

>The results showed that brain synchrony was equally strong when participants played in English as when they played in the mother’s native language.

>The researchers concluded that talking in an acquired language didn’t impinge on a mom’s ability to synchronize her brain activity with that of her child during interactive play. These results suggest that this key condition for effective learning and bonding can be met irrespective of language.
