• Aims:

  The present study aimed to investigate the effect of contexts (i.e., non-conflicting context versus conflicting context) on bilingual language switch costs during language comprehension.

  Methodology:

  Thirty-two unbalance Chinese-English bilinguals completed a modified comprehension-based language-switching task in two contexts. They made a judgement about the colour meaning of the word. In the non-conflicting context all words were presented in white ink, while in the conflicting context the words were printed in an inconsistent ink colour.

  Data and analysis:

  Reaction time and accuracy data were analysed using mixed-effects models.

  Findings/conclusions:

  Results showed that the switch costs were larger in the conflicting context than in the non-conflicting context. Further, in the non-conflicting context an asymmetrical switch cost with larger costs for the second language was observed as compared to symmetrical switch costs in the conflicting context.

  Originality:

  This is the first study that indicates that bilingual comprehension-based language control adapts flexibly depending on the context, just as during bilingual production.

  Significance/implications:

  These findings supported and expanded the classic adaptive control hypothesis.
