本研究探讨了后缀异形与复杂词加工的相关性。问题是形态范畴的结构不变性（即，缺乏同形异形）会影响芬兰语派生词的处理。一系列的四个视觉词汇决策实验中，表面和基础频率交替操作显示，两个不变的后缀，即命名-stO和死形容词-hkO，表现出可靠的基础频率的影响，而两个类别的后缀异形，deverbal -Us和死形容词-（U）Us，只有表面频率起作用。进一步的实验表明，即使使用-（U）Us的最常见变体，即-Ude-，响应延迟也仅是表面频率的函数。它表明，无论是从这里的实验结果，也没有以前的研究结果处理芬兰语单词可以占后缀频率，频率比之间的派生词和它的基地，或形态生产力在任何直接的方式。我们的结论是，缺乏同构，即，结构不变性，显着增加词缀的显着性，因此增强形态分解。这一发现的词汇处理模型的影响进行了讨论。
This study explores the relevance of suffix allomorphy for processing complex words. The question is whether structural invariance of the morphological category (i.e., lack of allomorphy) would affect the processing of Finnish derived words. A series of four visual lexical decision experiments in which alternatively surface and base frequency was manipulated showed that the two invariant suffixes, namely denominal -stO and deadjectival -hkO, showed reliable effects of base frequency, whereas for the two categories with suffix allomorphy, deverbal -Us and deadjectival -(U)Us, only surface frequency played a role. A further experiment showed that even with the most frequent variant of -(U) Us, namely -Ude-, response latencies were a function of surface frequency only. It is shown that neither the results from the experiments here nor previous findings from processing Finnish words can be accounted for by suffix frequency, the frequency ratio between the derived word and its base, or morphological productivity in any straightforward manner. We conclude that the lack of allomorphy, that is, structural invariance, significantly adds to affixal salience and therefore enhances morphological decomposition. The implications of this finding for models of lexical processing are discussed.
