According to a prominent account of inflectional encoding (Pinker, 1999; Pinker & Ullman, 2002b), regular forms are encoded by a rule-governed combination of stems and affixes, whereas irregular forms are retrieved from memory while inhibiting rule application. Sahin, Pinker, and Halgren (2006) suggested that this concerns a domain-general mechanism. Previous research on domain-general inhibition has shown that when switching between tasks, languages, or phrase types, an asymmetrical switch cost is obtained, which has been attributed to overcoming previous inhibition of the predominant response. If generating an irregular form involves rule inhibition, then switching from an irregular to a regular form should require overcoming previous inhibition and delay responding. We tested this in three experiments on producing the past tense in Dutch. We observed that an asymmetrical switch cost is obtained when switching between inflecting and reading verbs, but not when switching between encoding irregular and regular forms. These results suggest that the production of irregular forms does not involve the type of domain-general inhibition involved in switching between tasks, languages, or phrase types.

域一般抑制在变形编码中的作用：产生过去式。

根据屈折编码的一个重要说明（Pinker，1999； Pinker＆Ullman，2002b），规则形式是由规则控制的词干和词缀组合编码的，而不规则形式则是从内存中检索出来的，同时抑制了规则的应用。Sahin，Pinker和Halgren（2006）认为这与领域通用机制有关。先前对领域通用抑制的研究表明，在任务，语言或短语类型之间进行切换时，会获得不对称的切换成本，这归因于克服了先前对主要响应的抑制。如果生成不规则形式涉及规则禁止，则从不规则形式切换为规则形式应要求克服先前的禁止和延迟响应。我们在三个实验中用荷兰语产生过去式进行了测试。我们观察到，在屈折动词和动词动词之间进行切换时会获得非对称的切换成本，而在编码不规则形式和规则形式之间进行切换时则不会获得非对称切换成本。这些结果表明，不规则形式的产生不涉及在任务，语言或短语类型之间切换时涉及的领域一般抑制类型。
