title: Switch costs when reading aloud words and nonwords: evidence for shifting route emphasis?
abstract: Reynolds and Besner (2005) examined contextual control over the use of lexical and nonlexical routes by requiring participants to alternate between reading pairs of low-frequency exception words and pairs of nonwords. Their main finding was that latencies for both words (e.g., wad) and nonwords (e.g.,flad) were slower when the immediately preceding trial involved the opposite item type rather than the same item type (a switch cost). The authors interpreted this result as evidence that under certain circumstances, readers have the ability to shift emphasis between their lexical and nonlexical routes. The present research shows that these results can be replicated using Reynolds and Besner's items; however, the switch cost for words, but not for nonwords, disappears when more easily named nonwords are used. This result suggests that Reynolds and Besner's results were likely due to something other than shifting route emphasis.
