词法是词汇结构中一个离散的、独立的元素，还是仅仅反映了系统对单词正字法和语义属性之间存在的统计相关性的微调？希伯来语提供了一个独特的机会来检查大脑的形态学处理，因为它丰富的形态学系统。在fMRI隐藏启动实验中，我们研究了涉及希伯来语内隐形态学处理的神经网络。在lMFG和lIFG中，当启动物在形态学上与靶标相关时，激活显著降低。这种效应不受形态启动词语义透明度的影响，在语义或正字法条件下也没有发现。在lIPL中发现了额外的形态学相关的激活降低，尽管在那里，激活被语义透明度显著调节。我们关于内隐词法加工的研究结果表明，词法是词汇视觉加工的一个自动和独特的方面。这些结果也与先前获得的行为数据相吻合，这些数据表明形态处理在阅读希伯来语中起着核心作用。
Is morphology a discrete and independent element of lexical structure or does it simply reflect a fine-tuning of the system to the statistical correlation that exists among orthographic and semantic properties of words? Hebrew provides a unique opportunity to examine morphological processing in the brain because of its rich morphological system. In an fMRI masked priming experiment we investigated the neural networks involved in implicit morphological processing in Hebrew. In the lMFG and lIFG, activation was found to be significantly reduced when the primes were morphologically related to the targets. This effect was not influenced by the semantic transparency of the morphological prime, and was not found in the semantic or orthographic condition. Additional morphologically related decrease in activation was found in the lIPL although there, activation was significantly modulated by semantic transparency. Our findings regarding implicit morphological processing suggest that morphology is an automatic and distinct aspect of visually processing words. These results also coincide with the behavioral data previously obtained demonstrating the central role of morphological processing in reading Hebrew.
