According to this theory, children learn languages more easily because the plasticity  of their developing brains lets them use both hemispheres in language acquisition, while in most adults, language  is lateralized to one hemisphere, usually the left.
Po ovoj teoriji, djeca lakše uče jezike zato što im plastičnost njihovih mozgova u razvoju dozvoljava uporabu obje hemisfere u usvajanju jezika, dok je kod većine odraslih jezik lateraliziran u jednoj hemisferi, obično u lijevoj.
