语言处理对认知要求很高，需要注意力资源来有效地选择和提取语言信息。先前的研究已经将瞳孔大小的变化与注意力的增加联系起来。然而，它是未知的，是否说话者的行为生态可能会影响不同的注意力资源参与会话。对于双语者来说，这种行为可能涉及到一种以上语言的竞争信号，这种竞争如何产生可能会因交际环境而异。我们研究了在一个丰富的双语样本的理解过程中的单语和codeswitched语音的瞳孔大小的变化。在视觉世界任务中，参与者在听到选择目标图像的指令时看到成对的物体。指令要么是单语的，要么是从一种语言转换到另一种语言的代码。我们发现，只有那些在不同的交际语境中使用各自语言的双语者，以及那些具有高注意能力的双语者，才会对单语和语码转换言语表现出不同的注意力。对于那些普遍使用语码转换的双语者来说，单语和语码转换的言语处理过程是相似的，而不考虑注意技能。综上所述，这些结果表明，双语者招募不同的语言控制策略不同的交际目的。语言使用的干扰语境决定了语言加工过程中的注意控制投入。
Language processing is cognitively demanding, requiring attentional resources to efficiently select and extract linguistic information as utterances unfold. Previous research has associated changes in pupil size with increased attentional effort. However, it is unknown whether the behavioral ecology of speakers may differentially affect engagement of attentional resources involved in conversation. For bilinguals, such an act potentially involves competing signals in more than one language and how this competition arises may differ across communicative contexts. We examined changes in pupil size during the comprehension of unilingual and codeswitched speech in a richly-characterized bilingual sample. In a visual-world task, participants saw pairs of objects as they heard instructions to select a target image. Instructions were either unilingual or codeswitched from one language to the other. We found that only bilinguals who use each of their languages in separate communicative contexts and who have high attention ability, show differential attention to unilingual and codeswitched speech. Bilinguals for whom codeswitching is common practice process unilingual and codeswitched speech similarly, regardless of attentional skill. Taken together, these results suggest that bilinguals recruit different language control strategies for distinct communicative purposes. The interactional context of language use critically determines attentional control engagement during language processing.
