摘要 西班牙语-英语双语者很少在西班牙语助动词 haber（“有”）和分词（例如“Ella ha voted”；“She has voted”）之间进行完美结构的语码转换。然而，它们在某种程度上可能会在西班牙语助词 estar（“to be”）和分词（“Ella está voter”；“She is voter”）之间切换进行式结构。这种现象被称为“助动词不对称”。关于为什么会发生这种情况的一个假设是，estar 具有更多的语义权重，因为它也充当独立动词，而 haber 几乎专门用作助动词。为了检验这个假设，我们采用了一个联结主义模型来产生自发的语码转换。通过模拟实验，我们表明，i）模型中出现了不对称性，ii）当使用 haber 作为主要动词时，不对称性消失了，这增加了语义权重。因此，哈伯语义权重的缺乏确实可能造成不对称。
Abstract Spanish–English bilinguals rarely code-switch in the perfect structure between the Spanish auxiliary haber (“to have”) and the participle (e.g., “Ella ha voted”; “She has voted”). However, they are somewhat likely to switch in the progressive structure between the Spanish auxiliary estar (“to be”) and the participle (“Ella está voting”; “She is voting”). This phenomenon is known as the “auxiliary phrase asymmetry”. One hypothesis as to why this occurs is that estar has more semantic weight as it also functions as an independent verb, whereas haber is almost exclusively used as an auxiliary verb. To test this hypothesis, we employed a connectionist model that produces spontaneous code-switches. Through simulation experiments, we showed that i) the asymmetry emerges in the model and that ii) the asymmetry disappears when using haber also as a main verb, which adds semantic weight. Therefore, the lack of semantic weight of haber may indeed cause the asymmetry.
