The two-stage theory of lexical production distinguishes the retrieval of lemmas from the subsequent retrieval of the forms of words. The information made available by lemma retrieval includes semantic and grammatical details that are specific to a particular word, but not the direct specification of its phonological or orthographic form. This theory makes very strong predictions regarding the dissociability of these information types. In this report, we present the case of an Italian anomic patient whose performance bears on these predictions. In various naming tasks this patient's intact ability to identify the grammatical gender of words that he cannot produce stands in stark contrast with his inability to provide any information regarding particular lexical forms. We document the reliability of this performance pattern, and we discuss the significance of this pattern both in terms of the support it provides for the two-stage theory of lexical retrieval and in terms of the evidence it furnishes regarding the mental specification of grammatical information.
词汇生成的两阶段理论区分了词元的检索与随后单词形式的检索。词元检索所提供的信息包括特定单词的语义和语法细节，但不包括其语音或拼写形式的直接规范。该理论对这些信息类型的可分离性做出了非常有力的预测。在本报告中，我们介绍了一位意大利失语症患者的病例，其表现与这些预测相关。在各种命名任务中，这位患者能够识别出他无法说出的单词的语法性，但却无法提供任何有关特定词汇形式的信息，这两者形成了鲜明对比。我们记录了这种表现模式的可靠性，并从它为词汇检索的两阶段理论提供的支持以及它所提供的关于语法信息心理规范的证据这两个方面讨论了这种模式的意义。
