Does being bilingual improve memory?

Bilingualism enhances working memory in sequential bilingual children from low SES backgrounds. Bilingual benefits are found in language-independent working memory tasks that involve both storage and processing. Higher bilingual proficiency is associated with better verbal working memory performance.

Why do bilinguals have better memory?

The main reason suggested for bilinguals’ advantage is their need to process and manage the two languages, which are simultaneously activated whenever one of the languages is used [8,9,10,11]. This simultaneous activation requires a higher working memory (WM) capacity.
