There has been many researches on humans as far as learning process is concerned.Some theories stand for a different learning process on bilinguals. Apparently, we learn the idea or thing and identify it to the word. But if this idea is learned from birth, bilingual group identifies both words as one,
Such an effect enables bilingual being to learn more languages more easily.
