The majority of Japanese complex kanji consist of two subword units (radicals), and each radical is differentiated according to its combinability. Radical-type frequency is defined as the number of radical companions (NC) functioning as the number of characters containing that radical. The current study is intended to address the question of whether the NC plays a role in kanji character activation under a multi-radical-display (MRD) instead of a tachistoscopic display. An MRD task was used in which the NC was manipulated and the frequency of use of the whole characters was matched on average across the experimental conditions. Participants were divided into two groups (good knowledge vs poor knowledge) according to the score of a kanji completion task. The participants’ task was to select an appropriate combination of radicals to compose a legitimate character under the MRD condition. The poor-knowledge group yielded relatively more errors than did the good-knowledge group in the low-NC condition, whereas the good-knowledge group yielded more errors in the high- NC condition than in the low-NC condition. These results demonstrate the different influences of NC as metaknowledge (tacit knowledge of radical productivity) in both good and poor readers.
