The relationship between stem and whole-word frequency was investigated by simultaneously manipulating both frequency measures in a set of inflected verbs. In Experiment 1, these verbs were presented in isolation as part of a lexical decision task, and an effect of stem frequency only was observed. In Experiment 2, the same verbs were presented in sentences in a self-paced reading task, and an interaction between stem and whole-word frequency was observed. These findings contradict "either-or" models of morphological processing that assume two separate and independent processing routes for morphologically complex words, and also provide further evidence that the relationship between stem and whole-word frequency effects is context-sensitive.
