研究人员对以色列 15 名大学水平的男性普通读者在语音和拼写单词识别任务中的大脑活动进行了检查。获得了电生理学（事件相关电位，ERP）和行为测量。数据表明，(a) 所有实验任务的行为准确性几乎都是完美的，(b) 尽管在实验任务中引发了 P200 和 N400 ERP 组件，但在语音任务中，这些组件的潜伏期明显更长，幅度也明显更高。元音信息的变化对任何类型任务中的单词识别都没有影响。结果表明，在熟练的希伯来语读者中，单词识别过程中的语音处理可能比拼写处理更费力，并且可能需要更多的认知资源。此外，元音所代表的额外语音信息似乎对该人群的单词识别贡献不大。这些发现支持了早期关于希伯来语熟练阅读的研究以及当前的阅读理论模型。
Brain activity among 15 male, college-level, normal readers in Israel was examined during phonological and orthographic word-recognition tasks. Both electrophysiological (event-related potentials, or ERPs) and behavioral measures were obtained. Data indicated that (a) behavioral accuracy was almost perfect for all the experimental tasks, and (b) although P200 and N400 ERP components were elicited in the experimental tasks, the latencies of those components were significantly longer and their amplitudes significantly higher in the phonological task. Variations in vowel information had no effect on word recognition in either type of task. The results suggest that among skilled readers of Hebrew, phonological processing during word recognition may be more effortful and may demand greater cognitive resources than orthographic processing. Furthermore, the additional phonological information represented in vowels appears to contribute little to word recognition in this population. These findings support earlier research on skilled reading in Hebrew as well as current theoretical models of reading.
