The role of morphological, semantic, and form-based factors in the early stages of visual word recognition was investigated across different SOAs in a masked priming paradigm, focusing on English derivational morphology. In a first set of experiments, stimulus pairs co-varying in morphological decomposability and in semantic and orthographic relatedness were presented at three SOAs (36, 48, and 72 ms). No effects of orthographic relatedness were found at any SOA. Semantic relatedness did not interact with effects of morphological decomposability, which came through strongly at all SOAs, even for pseudo-suffixed pairs such as archer-arch. Derivational morphological effects in masked priming seem to be primarily driven by morphological decomposability at an early stage of visual word recognition, and are independent of semantic factors. A second experiment reversed the order of prime and target (stem-derived rather than derived-stem), and again found that morphological priming did not interact with semantic relatedness. This points to an early segmentation process that is driven by morphological decomposability and not by the structure or content of central lexical representations.
在一个掩蔽启动范式中，针对不同的刺激呈现间隔（SOA），研究了形态、语义和基于形式的因素在视觉单词识别早期阶段的作用，重点关注英语派生形态学。在第一组实验中，在三个刺激呈现间隔（36毫秒、48毫秒和72毫秒）下呈现了在形态可分解性以及语义和正字法相关性方面共同变化的刺激对。在任何刺激呈现间隔下均未发现正字法相关性的影响。语义相关性并未与形态可分解性的影响相互作用，形态可分解性在所有刺激呈现间隔下都表现出强烈影响，即使对于像archer - arch这样的假后缀对也是如此。掩蔽启动中的派生形态学效应似乎在视觉单词识别的早期阶段主要由形态可分解性驱动，并且独立于语义因素。第二个实验颠倒了启动词和目标词的顺序（词干派生而非派生 - 词干），并且再次发现形态启动并未与语义相关性相互作用。这表明存在一个由形态可分解性驱动而非由中心词汇表征的结构或内容驱动的早期分割过程。
