We present evidence that semantic errors in object naming can arise not only from impairment to the semantic system but also from damage to input and output processes. Although each of these levels of disruption can result in similar types of semantic errors in object naming, they have different types of consequences for performance on other lexical tasks, such as comprehension and naming to definition. We show that the analysis of the co-occurrence of semantic errors in naming with different patterns of performance in other lexical processing tasks can be used to localise the source of semantic errors in the naming process. Finally, we argue that the similarity of semantic errors in object naming, resulting from damage to different components of the naming processes by which they are activated by visual input, as well as the processes by which they activate output representations.
我们提供的证据表明，物体命名中的语义错误不仅可能源于语义系统的损伤，还可能源于输入和输出过程的损伤。尽管这些不同层面的干扰在物体命名中都可能导致相似类型的语义错误，但它们对其他词汇任务（如理解和根据定义命名）的表现会产生不同类型的影响。我们表明，通过分析命名中语义错误与其他词汇处理任务中不同表现模式的共现情况，可以确定命名过程中语义错误的来源。最后，我们认为，物体命名中的语义错误具有相似性，这是由于视觉输入激活命名过程的不同组成部分以及它们激活输出表征的过程受到损伤所致。
