In lexical decision, to date few studies in English have found a reliable pseudohomophone priming advantage with orthographically similar primes (the klip-plip effect; Frost, Ahissar, Gotesman, & Tayeb, 2003; see Rastle & Brysbaert, 2006, for a review). On the basis of the Bayseian reader model of lexical decision (Norris, 2006, 2009), we hypothesized that this was because in previous studies, lexical decisions could have been made without finding a match between the input and a unique lexical representation. Consistent with our hypothesis, we found that words from dense neighborhoods showed neither an orthographic form priming effect nor a pseudohomophone priming advantage; in contrast, with words from a sparse lexical neighborhood, a sizeable orthographic form priming effect was found, and a robust pseudohomophone priming advantage, which was not limited to the overlap of onset phoneme, was also observed. Identity primes produced greater facilitation than pseudohomophone primes. We consider the implication of these findings for the role of assembled phonology in lexical access.
