<p>Perimetric complexity, which is a simple metric of character (letter) complexity defined by an image's area and peripheral length, has been widely used, especially in alphabetic orthographies. We examined whether perimetric complexity is also a valid index for Japanese <i>kana</i> characters (<i>hiragana and katakana</i>) by comparing it with subjective complexity. We obtained evaluations of subjective complexities from Japanese and English speakers and calculated the mean of each character for each type of speaker for character-based analyses. The analyses revealed three main findings: (a) Perimetric complexity was highly correlated with subjective complexity (<i>r</i>s > .85), and its correlation was higher than that between the subjective complexity and other measures for character complexity (i.e., stroke count). (b) The perimetric complexities were highly correlated across different typefaces, except for significantly different typefaces. (c) Subjective complexity was highly correlated between Japanese and English speakers. These findings suggest that perimetric complexity can also be used as an index for Japanese <i>kana</i> character complexity.</p>

Although online research has shown promise as an alternative to laboratory research, it is unsuitable for the mere exposure effect because it is unknown whether participants sufficiently pay attention to repeated stimuli. To overcome this problem, we developed an online research method using exposure frequency in everyday life, which was combined with a cross-cultural comparison to consider the effect of confounding factors. Participants familiar and unfamiliar (Japanese and English speakers) with kana characters evaluated their attractiveness. After standardizing the attractiveness for each participant, we calculated the mean of each character’s view for each type of speaker to calculate a character-based correlation. The result of the Japanese speakers showed a moderate positive correlation between attractiveness and log-transformed exposure frequency to the characters counted by a Japanese corpus, indicating an occurrence of the mere exposure effect. This result cannot be explained by such confounding factors as the visual aspects of the characters due to a non-significant correlation in the English speakers. This study provided a more appropriate way to study the mere exposure effect in online environments.

本研究の目的は,記憶や流暢性現象(真実性効果など)において重要な要因と考えられている書体の読みやすさに書体への接触,使用経験が関与するのか明らかにすることである。そこで,大学生を対象として,無意味文字列に対する書体の読みやすさと接触頻度,使用頻度のWeb調査(7件法のリッカート法)を行い,これらの関係を検討した。書体ごとの評定値を平均し,相関係数を算出したところ,読みやすさと接触頻度で.69,読みやすさと使用頻度で.77の高い正の相関が有意であった。しかし,特徴的な形態の書体や,特定の種類の書体では接触,使用頻度に関係なく,読みやすさが判断されていた。この結果は,普段から目にすることが多く,使用する機会の多い書体が読みやすいと判断される一方で,形態的要因から読みやすさが判断される書体も存在することを示唆する。
