Interactive processing of phonological information in reading Japanese Kanji character words and their phonemic radicals

Kanji are categorized into four types based on the combinations of "subword validity" (when the right phonemic radical represents the same On-reading as the whole Kanji character) and "radical-neighbor consistency" (when the whole Kanji character represents the same On-reading as all of its neighbor characters). The study demonstrated that both subword validity and radical-neighbor consistency affect naming latencies and error rates regardless of character frequency. The study also demonstrated that the subword validity affects ease of extraction of a subword's phonology. These results suggest that the phonology of the whole Kanji competes with the subword's phonology. Moreover, the competition is stronger when the radical-neighbors aid in extracting the phonology of the whole Kanji.
