語義と視覚表現の意味の一致が単語処理に及ぼす影響：プライミング効果による検討

抄録

To demonstrate the effects of harmonization between a word’s semantics and its
typographies on human language word processing, we conducted a series of priming ex-
periments using a word-fragment completion task. In the learning phase of experiment
1, words were presented visually as typography was manipulated to be either har-
monized or anti-harmonized with a word’s semantics. The results indicated that the
visual processing of a word was facilitated when the semantics of the word were harmo-
nized with its typographies, compared with instances where they were anti-harmonized,
which was observed as a result of decreased phonetic priming. In experiment 2, it was
demonstrated that priming was decreased by harmonized typographies, but this decline
was canceled by presented speech sounds compared with the results of experiment 1
although neutral speech sound recordings of words were presented with letters visually
presented as words. In experiment 3, the harmonization was manipulated using not
only letters but also speech sounds that were manipulated to be harmonized or anti-
harmonized. The results showed that the processing of letters was interfered with by
those harmonized speech sounds. These results imply that greater processing resources
were used for the sensory modality that was manipulated its harmonization.
