title: Is there an effect of print exposure on the word frequency effect and the neighborhood size effect?
abstract: Orthographic and phonological processing skills have been shown to vary as a function of reader skill (Stanovich & West, Reading Research Quarterly, 24, 402-433, 1989; Unsworth & Pexman, Quarterly Journal of Experimental Psychology, 56A, 63-81, 2003). One variable known to contribute to differences between readers of higher and lower skill is amount of print exposure: higher skilled readers read more often than lower skilled readers, and their increased print exposure is associated with faster responding to words and nonwords in lexical decision tasks. The present experiments examined the effect of print exposure on the word frequency effect and neighborhood size effect. We conclude that the different outcomes reported in previous studies (Chateau & Jared, Memory and Cognition, 28, 143-153, 2000; Lewellen, Goldinger, Pisoni, & Greene, Journal of Experimental Psychology: General, 122, 316-330, 1993) were due to the type of nonwords used in the lexical decision task (regular nonwords versus pseudohomophones). Our results are explained in terms of differences in the reliance on orthographic and phonological information between readers of higher and lower print exposure.
