We examined how Japanese non-synesthetes associate colors to kana characters (Japanese syllabic graphemes). Kana consists of two distinct and corresponding subsets, hiragana and katakana, which represent the same set of syllables but differ in their shapes and usage, etc. For each of 92 kana characters, participants chose the most suitable color from 11 basic color terms. The same test was repeated with a two-week interval. Results showed comparable biases and regularities in their kana-color associations, though, which were not as temporally consistent as those of grapheme-color synesthetes. As suggested for grapheme-color synesthetes in past studies, linguistic and cognitive properties of the characters and colors regulated their associations: earlier characters in the syllabary order tended to be associated with earlier colors in the Berlin and Kay’s typology order, color word frequency order, and/or the subjective color ranking order. Besides, color choices for hiragana characters and those for their katakana counterparts were remarkably consistent, showing that characters sharing the same sound tended to be associated with the same colors. This tendency is comparable with that reported for Japanese synesthetes. It is suggested that grapheme-color associations of both non-synesthetes and synesthetes depend on common linguistic and cognitive processes during language and knowledge acquisition.

物体認知における色の役割を巡ってはこれまで議論が続けられてきた.Tanaka & Presnell (1999)は,物体と特定の色との結び付きの度合い—色識別性が重要な要因であると主張した.すなわち,色識別性が高い物体(例:バナナ)の認知においては色が大きな役割を持つのに対して,色識別性が低い物体(例:テーブル)の認知では色は役割を持たないという主張である.しかし,過去の研究結果からは,自然物(例:果物・動物)の認知においては人工物(例:道具・家具)の場合に比べて色の有益性が高いことも示唆されている.本研究では,色の影響と,色識別性,カテゴリーの関係について検討を行った.物体分別課題を用いた4つの実験の結果,物体のカテゴリーに関係なく,色識別性の高い物体の認知においては色が大きな役割を持つこと,しかし同時に,色識別性の効果は実験文脈に依存することが示唆された.

The purpose of this study is to examine the relation between focal attention and color feature processing. Previous studies have shown that unattended objects could be detected more efficiently when the attended and the unattended objects are common in color feature. In a experiment, subjects were required to identify the color of a peripheral blob as well as the value and color of a digit in the focal attention. The spatial distribution of activation should be decrease with the distance from the focus of attention centered on the attended object. However, the distribution might be decrease with the distance from the fixation point. The dual-task experiment could be conducted to examine these possibilities.
