图片的命名通常被认为需要顺序访问存储的关于对象的结构知识、语义知识和存储的语音描述。获取这些不同类型的知识可能构成不连续的处理阶段;或者，信息可能从一种类型的描述连续地（级联地）传递到下一种类型的描述。离散阶段和级联帐户作出不同的预测对象之间的结构和语义相似性对图片命名的影响。离散阶段理论认为，结构相似性的影响应局限于对对象结构描述的获取过程，语义相似性的影响应局限于对语义知识的获取过程。级联帐户预测，这两个变量的影响可能会传递到随后的处理阶段。我们提出的证据来自正常的观察者和患者获得性疾病的图片命名，这支持级联模型。这样一个模型的理解获得性障碍的视觉对象处理的影响进行了讨论。
The naming of pictures is typically thought to require sequential access to stored structural knowledge about objects, to semantic knowledge, and to a stored phonological description. Access to these different types of knowledge may constitute discrete processing stages; alternatively, it may be that information is transmitted continuously (in cascade) from one type of description to the next. The discrete stage and the cascade accounts make different predictions about the effects of structural and semantic similarity between objects on picture naming. The discrete stage account maintains that the effects of structural similarity should be confined to the process of accessing an object's structural description, and the effects of semantic similarity should be confined to the process of accessing semantic knowledge. The cascade account predicts that the effect of both variables may be passed on to subsequent processing stages. We present evidence drawn from both normal observers and from a patient with an acquired disorder of picture naming, which supports the cascade model. The implications of such a model for understanding acquired disorders of visual object processing are discussed.
