Synesthesia is a phenomenon in which sensory inputs trigger additional percepts or cognitive processes. This article outlines a method to conduct psychological experiments with synesthetes. However, synesthesia is a subjective conscious experience possessed by only a small percentage of people, therefore, various difficulties arise when treating synesthesia as a subject of empirical psychological research. Consequently, we introduce definitions of synesthesia and the methods of objective measurement of synesthesia in psychological research proposed in previous studies. We further discuss various individual differences among synesthetes.

Grapheme-color synesthesia is a condition in which visual letters or characters induce a specific color sensation. It has been suggested that a range of linguistic properties influence synesthetic grapheme-color correspondence, but the influence of graphemic (orthographic) information is not well understood. In this experiment, synesthetes chose up to two synesthetic colors for each Japanese Kanji character. The results showed that characters that could be divided into right and left subcomponents (radicals) were associated with a higher number of synesthetic colors than characters that could not be divided. This tendency was stronger for projectors, who perceive colors visually in external space, than for associators, who perceive colors in their ‘minds eye’. The results of this study suggest that the graphemic information of Kanji characters affects the number of synesthetic colors, especially for projectors.

This article examines two types of nonarbitrary correspondences between apparently disconnected perceptual-cognitive entities—synesthesia and sound symbolism—the latter of which is a kind of crossmodal correspondence. First, the article describes the basic characteristics of these phenomena along with the similarities and differences between them. While both synesthesia and sound symbolism are intriguing matchings between different domains that are consistent over time, they differ in terms of their prevalence (rare vs. frequent) and idiosyncrasy (idiosyncratic vs. widely shared across individuals), and whether the concurrent is consciously experienced (conscious vs. not necessarily conscious). Although the similarities are often emphasized, the differences should never be neglected in the exploration of the underlying mechanisms of these phenomena. This article further discusses recent advances in these research fields, especially those showing a close relationship between language development and each of the two phenomena. Studies on synesthesia and sound symbolism should provide new insights into cognitive language processing.

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.

To explore effective proofreading methods this study focused on the characteristics of professional proofreaders and control participants who were not proofreading professionals. In an anomalous word detection task the performance of the proofreaders was better than control participants (Experiment 1). However, this better ability of proofreaders to detect anomalous words may not be due to lexical knowledge because the estimated vocabulary of the two groups was approximately the same. In the Stroop color-word task only the control participants demonstrated Stroop interference (Experiment 2). The change detection performance of the proofreaders was better than control participants in a change blindness task (Experiment 3). This better change detection ability, and the lack of interference in the Stroop test, suggests that proofreaders inhibit interference from destructive information and can conduct an exhaustive search for anomalous words. These characteristics of a high-level vision are regarded as keys for effective proofreading.
