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.
研究人员对以色列15名大学水平的正常男性读者在语音和正字法单词识别任务期间的大脑活动进行了检测。同时获取了电生理数据（事件相关电位，即ERP）和行为测量数据。数据表明：（a）所有实验任务的行为准确性几乎完美；（b）尽管在实验任务中诱发了P200和N400 ERP成分，但在语音任务中这些成分的潜伏期明显更长，波幅明显更高。元音信息的变化对两种任务类型中的单词识别均无影响。结果表明，在希伯来语熟练读者中，单词识别过程中的语音处理可能比正字法处理更加费力，且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群体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。
