Abstract: We adopted an improved dot-probe paradigm to investigate the dominant?effect of information?processing during emotional attention bias for proficient bilinguals and the reason for such effect. A 2(proficient bilinguals vs. nonproficient bilinguals)×3(the position of target stimuli and negative words: consistency vs. inconsistency vs. neutral)×2(cues presentation time: 100ms vs. 400ms) mixed design was conducted, where the reaction times and error rates of target stimuli were recorded. The results revealed that there was no significant difference between proficient and nonproficient bilinguals in attention orienting scores when the presentation time of cues was 100ms and 400ms. There was also no significant difference between these two groups in attention disengagement scores when the presentation time of cues was 100ms. However, the attention disengagement scores of proficient bilinguals were significantly lower than those of nonproficient bilinguals when the presentation time of cues was 400ms. These results suggest that proficient bilinguals relative to nonproficient bilinguals show high-level ability in attentional inhibition control on emotional information during the attention bias task and exhibit the bilingual dominant?effect of emotional information?processing. The reason for this dominant effect could be that proficient bilinguals relative to nonproficient bilinguals have high-level ability in attention disengagement on emotional information in the late stage of attention.
