Code-blending is the simultaneous expression of utterances using both a sign language and a spoken language. We expect that like code-switching, code-blending is linguistically constrained and thus we investigate two hypothesized constraints using an acceptability judgment task. Participants rated the acceptability of code-blended utterances designed to be consistent or inconsistent with these hypothesized constraints. We find strong support for the proposed constraint that each modality of code-blended utterances contributes content to a single proposition. We also find support for the proposed constraint that – at least for American Sign Language (ASL) and English – code-blended utterances make use of a single derivation which is realized using surface forms in the two languages, rather than two simultaneous derivations, one for each language. While this study was limited to ASL/English code-blending and further investigation is needed, we hope that this novel study will encourage future research comparing linguistic constraints on code-blending and code-switching.

双峰双语代码混合的语言特征：来自可接受性判断的证据


代码混合是指同时使用手语和口语同时表达话语。我们预计，与代码转换一样，代码混合在语言上受到限制，因此我们使用可接受性判断任务来研究两个假设的约束。参与者对设计为与这些假设的约束一致或不一致的代码混合话语的可接受性进行了评分。我们发现对所提出的约束的有力支持，即代码混合话语的每种模式都为单个命题贡献内容。我们还发现了对所提出的约束的支持，即至少对于美国手语 （ASL） 和英语来说，代码混合话语使用单一的派生，该派生是使用两种语言中的表面形式实现的，而不是两个同时派生，每种语言一个。虽然这项研究仅限于 ASL/英语代码混合，还需要进一步调查，但我们希望这项新颖的研究将鼓励未来比较代码混合和代码转换的语言限制的研究。
