Bimodal bilinguals master languages in two modalities, spoken and signed, and can use them simultaneously due to the independence of the articulators. This behavior, named code-blending, is one of the hallmarks of bimodal bilingualism. Lexical experiments on production and comprehension in American Sign Language/English showed that blending is not cognitively costly and facilitates lexical access. In this work, we replicated the blending advantage in lexical comprehension for hearing bimodal bilinguals with two other language pairs, French Sign Language (LSF)–French and Italian Sign Language (LIS)–Italian, and we explored whether the facilitation is also found at the sentential level. Results show that blended utterances for languages with incongruent word order like LIS–Italian were processed slower than monolingual utterances, while no difference was found when the word orders were congruent (LSF–French). We discuss these findings in light of linguistic theories of syntactic structure derivation in bimodal bilinguals.

处理超出词汇级别的代码混合：双重句法推导的证据？

双模式双语者掌握口语和手语两种模式的语言，并且由于发音器官的独立性，可以同时使用它们。这种行为称为代码混合，是双峰双语的标志之一。关于美国手语/英语的产生和理解的词汇实验表明，混合的认知成本并不高，并且有利于词汇访问。在这项工作中，我们复制了听力双模双语者与其他两种语言对（法语手语（LSF）-法语和意大利语手语（LIS）-意大利语）在词汇理解方面的混合优势，并且我们探讨了这种促进是否也存在于句子级别。结果表明，像 LIS-意大利语这样词序不一致的语言的混合话语的处理速度比单语话语慢，而当词序一致时（LSF-法语）则没有发现差异。我们根据双峰双语者句法结构推导的语言理论讨论这些发现。
