A recent computational model by Hayes and Wilson (2008) seemingly captures a diverse range of phonotactic phenomena without variables, contrasting with the presumptions of many formal theories. Here, we examine the plausibility of this approach by comparing generalizations of identity restrictions by this architecture and human learners. Whereas humans generalize identity restrictions broadly, to both native and non-native phonemes, the original model and several related variants failed to generalize to non-native phonemes. In contrast, a revised model equipped with variables more closely matches human behavior. These findings suggest that, like syntax, phonological grammars are endowed with algebraic relations among variables that support across-the-board generalizations.
海斯和威尔逊（2008年）最近提出的一个计算模型似乎在没有变量的情况下捕捉到了各种各样的音位配列现象，这与许多形式理论的假设形成了对比。在这里，我们通过比较这种架构和人类学习者对身份限制的概括来检验这种方法的合理性。人类广泛地将身份限制概括到母语和非母语音素上，而原始模型和几个相关变体却未能将其概括到非母语音素上。相比之下，一个配备了变量的修订模型更接近人类行为。这些发现表明，与句法一样，音系语法在变量之间具有代数关系，支持全面的概括。
