Further explorations of the consistency effect in word and nonword pronunciation

Three experiments explored the consistency effect in word and nonword pronunciation. All three experiments involved a common second phase in which subjects were required to pronounce a sequence of consistent and inconsistent words and nonwords. The experiments were distinguished by the nature of Phase 1. In Experiment 1, subjects pronounced a sequence of words and nonwords in which all the words were exceptions. In Experiment 2, all the items in this phase were consistent, and in Experiment 3, they were inconsistent. Consistency effects for words, as measured by pronunciation latency, were confined to Experiment 1. Consistency effects for nonwords were found in Experiment 2. No consistency effects were found for either words or nonwords in Experiment 3. There was clear evidence of a consistency effect for nonwords in Experiment 1 in terms of pronunciation errors, but the latency data were not significant. This is attributed to the very slow response times in this condition. All these data are compatible with both revised analogy and dual-route theories.
