The present study uses tip-of-the-tongue (TOT) states as a unique source of evidence to test the hypothesis of lexical access benefits for homophones - that is, whether low-frequency homophones, such as tee, inherit the lexical access benefits of their high-frequency homophonic counterparts, such as tea.We compared retrieval success rates for low-frequency homophones, for matched low-frequency controls, and for high-frequency controls with the combined frequency of the homophone set. In correct retrievals, low frequency homophones behaved according to their specific frequency, not differing from the low-frequency controls. However, retrieval failures revealed a different kind of homophone effect. When retrieval failed for targets with a homophone partner, access difficulties tended to be less profound than for low-frequency controls, ending closer to target retrieval more often than low-frequency controls (at Step 2; in a self-resolved TOT or in a TOT with a strong feeling of knowing), and ending far away from target retrieval less often than low-frequency controls (at Step 1; in a not GOT). These results provide evidence against the notion of shared word-form representations for homophonic targets but leave open a door for a weaker form of homophone effects, possibly arising from feedback activation that influences retrieval only when access is sufficiently slowed (as when retrieval fails). |
