Psychophysiological Responses to Kawaii Pictures With or Without Baby Schema

Baby schema has been considered a key stimulus that triggers feelings and thoughts of cuteness. Kawaii is a Japanese word that roughly translates to cute in English, but its meaning appears to be broader than cute. Specifically, cuteness is often regarded as synonymous with infant physical attractiveness, whereas kawaii is used not only for babies but also for noninfantile objects. In this study, psychophysiological responses were compared between two types of kawaii pictures: human babies and animals ( kawaii with baby schema) or objects such as desserts and dress accessories ( kawaii without baby schema). Twenty female university students were asked to view various pictures twice. Both types of kawaii pictures were rated to be more pleasant than neutral pictures, elicited a greater activation of the zygomaticus major muscles associated with smiling, and were viewed for a longer period when the same pictures were presented again. The effect of baby schema appeared in the zygomaticus major muscle activity, which was greater for pictures with baby schema. The findings suggest that the word kawaii expresses positive feelings that are more generic than infant attractiveness and that are associated with a motivation to approach a preferable object.
