The purpose of this study was to examine the effects of discriminability of radical cues in kanji on buildup of proactive interference by the use of the Brown-Peterson paradigm for kanji lists with the same radicals and different meanings (Exp.1) and with the same radicals and common associative meanings (Exp.2). In Exp.1, 48 students were assigned to one of the two list conditions. Each list consisted of three kanji letters with the same radicals and different meanings. Under the discriminative list condition, lists in three trials consisted of kanji letters with changed radicals in each trial. In the nondiscriminative list condition, all lists consisted of kanji letters with the same radicals in all trials. Three items were presented simultaneously by the slide projector at a 2.5 sec. rate, which was followed by the distractor task (20 sec). Then a written recall test was given for 15 sec. The main results were as follows: PI was built up as a function of trials under both the discriminative and the nondiscriminative lists.　But the amount of PI was larger for the nondiscriminative lists than for the discriminative lists. The finding that PI was built up under the discriminative list condition did not support our prediction. In Exp.2, 42 students were assigned to one of the same two list conditions as Exp.1. The lists of Exp. 2　consisted of the kanji lists with the same radicals and common associative meanings. The procedures were almost identical to Exp. 1. The main results were as follows: PI was built up as a function of trials under the nondiscriminative list, but not under the discriminative list. The performances in each trial were higher for Exp.2 than Exp.1 in each list condition. These findings suggested that the semantic cues evoked by the radicals facilitated recall in each trial. Our general hypothesis that buildup of PI is due to the effectiveness of retrieval cues was supported for the semantic cues in kanji with the same radicals.
