Abstract: The aim was to determine whether logical concepts acquired in onelanguage could be transferred to another language.Following Keats ＆Keats,the Australian psychologists'earlier studies with bilingual children inAustralia and Malaysia,a group of four-to seven-year-old children bilingualin Chinese (the language of the Hun nationality) and the language of theUygur nationality and a group of five-year-old children bilingual in Shanghaidialect and Beijing dialect were pretested in both languages and dialectsrespectively.They were then trained in one language or dialect on the conserva-tion of weight,posttested in their other language or dialect,and again onemonth later in both languages or dialects.Results showed that the conceptacquired in one of their language or dialect was immediately available in theother,thus confirmed Keats ＆ Keats'previous findings that language playeda minor part in the acquisition of cognitive concepts in children of this agegroup,except it seemed that these children would do slightly better on thesetasks if trained in their native language.
