<正>Objective:To investigate the neural electrophysiologieal activity underlying Chinese and Eng- lish Stroop tasks for Chinese English bilinguals.Methods:Event-related potentials（ERPs）were recorded in 14 Chinese bilinguals with a moderate command of English when they performed the Stroop task pre- sented in English words and Chinese characters

respectively.Results:In Chinese task version

it was found an increased positivity over bilateral front-polar regions on incongruent trials compared with congru- ent trials

followed by an increased negativity over fronto-central region and an increased positivity over occipital region.While in English task version

only the increased negativity was observed over fronto-cen- tral region

but with reduced amplitude and anterior distribution.Conclusion:This increased negativity was proposed as an index of the resolution processes of conflicting information in the incongruent situa- tion.The increased positivity over occipital region on Chinese incongruent trials may indicate visually rechecking effect for Chinese character.
