文本的阅读主要是左半球的功能。但是，也可以处理除单词或字母标识以外的属性（如字体或手写体样式）的文本。一些轶事观察表明，处理后者可能涉及右半球。我们设计了一个测试，使用相同的刺激，要求受试者首先匹配的基础上的字的身份和第二匹配的基础上的脚本风格。我们提供了两个版本，一个使用各种计算机字体，另一个使用不同个人的笔迹。我们测试了四名单侧病变的受试者，他们的特点是神经心理学测试和结构和/或功能MRI。我们发现，两个prosopagnosic主题与右侧梭状损害消除梭状脸面积和可能的权利视觉词形区受损的完成时间和/或准确性排序时，脚本风格，但表现更好的排序时，字的身份。与此相反，一个失读症患者左梭状回损害显示正常的准确性排序的脚本风格和正常或轻度升高的完成时间排序的风格，但显着延长阅读时间排序的字的身份。一名右侧内侧枕颞损伤的梭状回外侧区的面孔失认症患者在两项任务中都表现良好。右侧梭状回损伤患者与左侧梭状回损伤患者在表现上的对比表明，大脑半球的处理过程存在重要区别，这反映的不是刺激的类型，而是所需处理的性质。(C)2010爱思唯尔有限公司版权所有。
The reading of text is predominantly a left hemisphere function. However, it is also possible to process text for attributes other than word or letter identity, such as style of font or handwriting. Anecdotal observations have suggested that processing the latter may involve the right hemisphere. We devised a test that, using the identical stimuli, required subjects first to match on the basis of word identity and second to match on the basis of script style. We presented two versions, one using various computer fonts, and the other using the handwriting of different individuals. We tested four subjects with unilateral lesions who had been well characterized by neuropsychological testing and structural and/or functional MRI. We found that two prosopagnosic subjects with right lateral fusiform damage eliminating the fusiform face area and likely the right visual word form area were impaired in completion times and/or accuracy when sorting for script style, but performed better when sorting for word identity. In contrast, one alexic subject with left fusiform damage showed normal accuracy for sorting by script style and normal or mildly elevated completion times for sorting by style, but markedly prolonged reading times for sorting by word identity. A prosopagnosic subject with right medial occipitotemporal damage sparing areas in the lateral fusiform gyrus performed well on both tasks. The contrast in the performance of patients with right versus left fusiform damage suggests an important distinction in hemispheric processing that reflects not the type of stimulus but the nature of processing required.
