This research investigated the role of frequency and semantic factors in the processing of morphologically complex words. Unaffixed targets were immediately preceded by either inflected or derived primes that were either high or low in frequency. In Experiment 1, low-frequency inflections and derivations produced equivalent priming effects, whereas high-frequency inflections produced more priming than derivations. In Experiment 2, both semantic and morphological priming varied as a function of SOA (50, 150, and 250 ms). The difference in priming of inflections and derivations increased as SOA increased. Results suggest that frequency and semantic similarity interactively modulate the magnitude of morphological priming and, by inference, affect the processing of morphologically complex words. Dual-route and connectionist accounts are discussed.
本研究调查了频率和语义因素在形态复杂单词加工过程中的作用。未加词缀的目标词之前紧接着出现的是屈折变化或派生变化的启动词，这些启动词的频率有高有低。在实验1中，低频屈折变化和派生变化产生了同等的启动效应，而高频屈折变化产生的启动效应比派生变化更多。在实验2中，语义启动和形态启动均随刺激呈现间隔（50、150和250毫秒）而变化。随着刺激呈现间隔的增加，屈折变化和派生变化的启动差异增大。结果表明，频率和语义相似性交互调节形态启动的大小，并由此推断，影响形态复杂单词的加工。文中还讨论了双通道和联结主义的解释。
