Studies on the cerebral mechanisms of reading have mostly used Latin-based writing systems and assume that the left, but not the right, cerebral hemisphere is capable of phonological processing. The present study used Hebrew as the test language to examine the effects of phonological and orthographic information in the two hemispheres. In unvoweled Hebrew script, words are read via consonant information alone. We used two naming tasks with an interference paradigm, where phonemically, orthographically, and figurally incorrect vowel information conflicted with the consonant information of words presented in the left, right, or central visual fields. Interference patterns indicated that the left hemisphere automatically transforms graphemes into phonemes (Experiments 1 and 2), whereas the right hemisphere processes vowel diacritics as visual objects (Experiment 1), although it possesses some phonological categories (Experiment 2). The significance of these findings for models of visual word recognition in the cerebral hemispheres is discussed.
阅读的大脑机制研究大多使用基于拉丁语的书写系统，并假设左半球而不是右半球能够进行语音处理。本研究使用希伯来语作为测试语言，以检验两个半球中的语音和正字法信息的影响。在无元音的希伯来语脚本中，单词仅通过辅音信息来阅读。我们使用了带有干扰范式的两种命名任务，其中在语音上、正字法上和形象上不正确的元音信息与在左、右或中央视野中呈现的单词的辅音信息相冲突。干扰模式表明，左半球自动将字形转换为音素（实验 1 和 2），而右半球将元音变音符号作为视觉对象进行处理（实验 1），尽管它具有一些语音类别（实验 2）。这些发现对于大脑半球中视觉单词识别模型的意义进行了讨论。
