In order to examine the role of left perisylvian cortex in spelling, 13 individuals with lesions in this area were administered a comprehensive spelling battery. Their spelling of regular words, irregular words, and nonwords was compared with that of individuals with extrasylvian damage involving left inferior temporo-occipital cortex and normal controls. Perisylvian patients demonstrated a lexicality effect, with nonwords spelled worse than real words. This pattern contrasts with the deficit in irregular word spelling, or regularity effect, observed in extrasylvian patients. These findings confirm that damage to left perisylvian cortex results in impaired phonological processing required for sublexical spelling. Further, degraded phonological input to orthographic selection typically results in additional deficits in real word spelling.
为了研究左侧颞周皮质在拼写中的作用，对13名该区域有损伤的个体进行了一套全面的拼写测试。将他们对规则单词、不规则单词和非单词的拼写与涉及左侧颞枕叶皮质的颞叶外损伤个体及正常对照组进行了比较。颞周区患者表现出词汇性效应，非单词的拼写比真实单词差。这种模式与颞叶外患者中观察到的不规则单词拼写缺陷或规则性效应形成对比。这些发现证实，左侧颞周皮质损伤会导致亚词汇拼写所需的语音处理受损。此外，向正字法选择输入的语音信息退化通常会导致真实单词拼写出现额外缺陷。
