大量的实证和理论研究表明，形态结构决定着记忆中单词的表征，并且许多单词在处理过程中被分解为形态成分。作者研究了另一种方法，其中形态学产生的语义和语音代码的相互作用。一系列跨通道词汇判断实验表明，启动效应的大小反映了词汇之间语义和语音的重叠程度。至关重要的是，适度相似的项目产生中间促进作用（例如，迟到）。这种模式是观察到的词对表现出不同类型的形态关系，包括后缀干（例如，teacher-teach），后缀-后缀（suffixed-suffixed）（例如，圣人-圣人）和前缀-词干对（预热-加热）。结果可以理解的连接模型，使用分布式表示，而不是离散的词素。
A considerable body of empirical and theoretical research suggests that morphological structure governs the representation of words in memory and that many words are decomposed into morphological components in processing. The authors investigated an alternative approach in which morphology arises from the interaction of semantic and phonological codes. A series of cross-modal lexical decision experiments shows that the magnitude of priming reflects the degree of semantic and phonological overlap between words. Crucially, moderately similar items produce intermediate facilitation (e.g., lately-late). This pattern is observed for word pairs exhibiting different types of morphological relationships, including suffixed-stem (e.g., teacher-teach), suffixed-suffixed (e.g., saintly-sainthood) and prefixed-stem pairs (preheat-heat). The results can be understood in terms of connectionist models that use distributed representations rather than discrete morphemes.
