Assistant Professor Yang Hwajin from Singapore Management University (SMU) School of Social Sciences conducted studies on bilingualism and cognition. In one study Professor Yang found that low socioeconomic status children who spoke two languages performed better in behavioural tests than monolingual. Similar results where found in another study which involved infants of low socioeconomic status. Bilingual infants from low socioeconomic status displayed a greater cognitive development than monolingual infants of the same status.This can demonstrate that bilingualism could help the development of children in deprived environments.
