We investigated the necessary role of the right parietal lobe in visual word recognition using transcranial magnetic stimulation (TMS). TMS was applied to the right posterior parietal lobe and to a control area as participants read aloud words presented either in lower case or in mIxEd-cAsE. The words were presented either with unlimited duration and high contrast (Experiment 1), or with brief presentation and low-contrast (Experiments 2 and 3). In all three experiments, TMS over the parietal area disrupted reading, and in Experiments 2 and 3 this effect was most pronounced for mIxEd-cAsE words. This suggests that the right parietal lobe mediates the recognition of words in unfamiliar formats.
我们使用经颅磁刺激（TMS）研究了右侧顶叶在视觉单词识别中的必要作用。当参与者大声朗读以小写或混合大小写呈现的单词时，TMS被施加到右侧后顶叶和一个对照区域。单词呈现的持续时间不限且对比度高（实验1），或者呈现时间短暂且对比度低（实验2和实验3）。在所有三个实验中，顶叶区域的TMS干扰了阅读，并且在实验2和实验3中，这种效应在混合大小写单词中最为明显。这表明右侧顶叶介导了对不熟悉格式单词的识别。
