本研究在21例失语症患者和20例健康对照者中进行了表征动作和物体的词和图片的加工测试，测试任务包括图片命名（PN）、单个词阅读（WR）和词重复（WRP）。分析1有针对性的任务和词汇类别（名词-动词），揭示了更差的性能PN和动词项目的患者和对照组。对于分析2，我们使用在并发手势规范研究中收集的数据来沿着沿着手部图像参数（即，可以/不可以操纵的对象和涉及/不涉及精细手部运动的动作）。在这里，患者表现出相对困难的“可操作”的项目，而控制显示相反的模式。因此，虽然名词-动词的区别只是导致较低的动词准确性在各组之间，“可操作性”的区别揭示了患者和对照组参与者之间的“双重分离”。这些结果对具体化理论、词汇语义分离理论和意义在大脑中的组织理论都有启示。(C)2006年爱思唯尔公司All rights reserved.
The processing of words and Pictures representing actions and objects was tested in 21 aphasic patients and 20 healthy controls across three word production tasks: picture-naming (PN), single word reading (WR) and word repetition (WRP). Analysis 1 targeted task and lexical category (noun-verb), revealing worse performance on PN and verb items for both patients and control participants. For Analysis 2 we used data collected in a concurrent gesture norming Study to re-categorize the noun-verb items along hand imagery parameters (i.e., objects that can/cannot be manipulated and actions which do/do not involve fine hand movements). Here, patients displayed relative difficulty with the 'manipulable' items, while controls displayed the opposite pattern. Therefore, whereas the noun-verb distinction resulted simply in lower verb accuracy across groups, the 'manipulability' distinction revealed a 'double-dissociation' between patients and control participants. These results carry implications for theories of embodiment, lexico-semantic dissociations, and the organization of meaning in the brain. (C) 2006 Elsevier Inc. All rights reserved.
