The purpose of this study was to investigate the effects of bilingualism on children's cognitive ability by comparing Korean-Chinese bilingual with Chinese monolingual children in Yanji, China. The subjects were 111 children of 4 and 5 years of age, 58 of whom were bilingual and 53 were monolingual in Yanji. Bilingual children spoke Korean at home but Chinese in the community and at preschool. These children's Chinese fluency that assessed chinese reading and speaking level by parents questionnaires revealed that they were fully bilingual. The instruments used to measure children's cognitive ability were Visually-Cued Recall Task, cardinality task. Cardinality task was consisted of a knowledge analysis task and a control of processing task(Bialystok & Codd, 1997). A 3(age) by 2(mono-bilingual) ANCOVA was performed for cardinality task and memory task scare as the covariate because monolingual children performed memory task better than bilingual children. The results show that the older children performed on the knowledge analysis task and the controllcontrol of processing task better than the younger ones, but there was no significant difference between two language groups.
