Abstract: Research interest in cuteness perception and its effects on subsequent behavior and physiological responses has recently been increasing. The purpose of the present study was to produce a dataset of Japanese infant faces that are free of portrait rights and can be used for cuteness research. A total of 80 original facial images of 6-month-old infants were collected from their parents. The cuteness level of each picture was rated on a 7-point scale by 200 Japanese people (100 men and 100 women in their 20s-60s). Prototypical high- and low-cuteness faces were created by averaging the top 10 and bottom 10 faces according to the mean cuteness ratings. Then, 50 composite faces were made by mixing two faces randomly chosen from the 60 unused middle-cuteness faces. The normative cuteness ratings of these composite faces were obtained from 229 Japanese men and women in their 20s-60s. The shape of each composite face was transformed to be cuter (+50%) or less cute (-50%) along a continuum between the high- and low-cuteness prototypical faces. A two-alternative forced-choice task (N = 587) confirmed that cuteness discrimination was better than the chance level for all 50 face pairs. Moreover, the results showed that young men had poorer sensitivity to cuteness differences in infant faces than older men and women of any age. This Japanese Cute Infant Face (JCIF, “jay-sif”) dataset, including composite face images and normative rating scores, is publicly available online.

日本語によるコメント:日本で集めた80枚の乳児顔(6ヶ月齢)について「かわいさ」の評定を行い,得点が高かった10名の平均顔と低かった10名の平均顔を作成しました。この顔形状の差は,従来からベビースキーマと呼ばれてきた物理的な「かわいさ」次元に相当します。この次元は多くの人が識別できるのですが,若い男性には伝わりにくいことが分かりました。客観的な「かわいさ(cuteness)」と主観的な「かわいい(kawaii)」は区別できるという研究の一環として行ったものです。作成した画像とデータはすべてOSFで公開しています。
