人们普遍认为视觉单词识别系统对形态结构敏感（例如，“hunter”=“hunt”+“er”）。此外，已经假设对形态复杂的词（例如，“Hunter”）仅在复合形式的含义可以从其成分的含义导出时才出现（例如，“hunt”和“er”）。然而，最近的行为工作，使用掩蔽启动表明，形态分析可以发生在早期，正字法的水平，几乎没有语义的影响。本研究检查了在真正的形态关系（例如，“hunter”-“HUNT”）、明显的形态学关系（“corner”-“CORN”）和无形态学关系（“brothel”-“BROTH”）。神经启动的指标减少N400 ERP组件相关的目标之前，相关的启动，相比，目标之前，不相关的启动。形态结构（“角”-“玉米”）的外观导致了强大的行为和神经启动，其幅度与观察到的对真正的形态关系和大于非形态对。研究结果支持一个纯粹的结构语素分割程序在视觉词知觉的早期阶段。
There is broad consensus that the visual word recognition system is sensitive to morphological Structure (e.g., "hunter" = "hunt" + "er"). Moreover, it has been assumed that the analysis of morphologically complex words (e.g., "hunter") occurs only if the meaning of the complex form can be derived from the meanings of its constituents (e.g., "hunt" and "er"). However, recent behavioral work using masked priming has Suggested that morphological analysis can occur at an early, orthographic level, with little influence from semantics. The present investigation examined the neurophysiological correlates of masked priming in conditions of a genuine morphological relationship (e.g., "hunter"-"HUNT"), an apparent morphological relationship ("corner"-"CORN"), and no morphological relationship ("brothel"-"BROTH"). Neural priming was indexed by the reduction of the N400 ERP component associated with targets preceded by related primes, as compared to targets preceded by unrelated primes. The mere appearance of morphological structure ("corner"-"CORN") resulted in robust behavioral and neural priming, whose magnitude was similar to that observed in pairs with genuine morphological relationship and greater than that in the nonmorphological pairs. The results support a purely structural morphemic segmentation procedure operating in the early stages of visual word perception.
