Abstract: | The present research was designed to extend research by Strain et al (1995) who found that imageability facilitates naming of low-frequency irregular words. The authors hypothesized that the impact of imageability on naming performance will vary with phonological reading ability. For participants who score high in phonological reading ability, the effect of imageability should be seen primarily on naming of low-frequency exception words where the orthography-to-phonology mappings are not strong. For participants who score low in phonological reading ability, the mapping of orthography onto phonology is presumably inefficient for all types of low-frequency words. Accordingly, for these participants, it was predicted that imageability would affect naming of both exception and regular words. 90 college students served as Ss. Exp 1 shows that the impact of imageability on word naming varies with phonological coding skill. In Exp 2, the effect of imageability on naming low-frequency irregular words was shown to occur across an extended set of items. Together, the present findings support the notion that semantics may play a role in phonological coding when the mappings between orthography and phonology are weak.
