An eye-movement database of bilingual language control for Chinese-English bilinguals

The current absence of an eye-tracking database that explores bilingual language control and how intra-sentence code-switching types influence the language control process limits our deeper understanding of bilingual control mechanisms. To address this issue, we present a database containing eye-movement recordings collected during a silent reading task combined with language switching paradigm. The database contains typical measures of eye movement data of 160 Chinese and their translation equivalent English words from 40 high-proficient and 40 low-proficient participants across 1280 Chinese, English and intra-sentential code-switching sentences. This database enables researchers to test the impacts of both intra-sentential code-switching and the second language proficiency on bilingual language control and the underlying cognitive mechanisms.
