Abstract: Previous research has shown that bilingual nonselective and selective lexical access requiring the development of cognitive control ability which depends on language proficiency. The present series of studies extends this finding by identifying the contextual effect on cognitive control which can appear after lexical access or before it, that is the reason of nonselective and selective access. Considering of the situation that cognitive control under context can restrict the activation of non-target language before lexical access, the hypothesis proposed by BIA+ model which has suggested that bilingual lexical activation was nonselective should be revised, also is the idea that the cognitive control ability depends mainly on proficiency

Key words: bilingual, lexical access mechanism, proficiency, context, cognitive control
