Cultural background shapes attraction to bowing

Summary and headline written by AI from the source article. How we work
Jun Kawahara of Hokkaido University and Takayuki Osugi of Yamagata University investigated how bowing influences perceptions of attractiveness among people from different cultures.
The researchers first observed that Japanese participants found faces tilted to mimic bowing more attractive than upright faces. They then wanted to determine if this preference stemmed from a universal social signal or Japanese culture. The team used three-dimensional computer models to test how people rated attractiveness when viewing figures standing or bowing.
They initially found that Japanese participants consistently rated bowing figures as more attractive, while participants from the United States, Brazil, India, China, and Taiwan did not share this preference. However, these initial tests used only East Asian-appearing models, leading the researchers to suspect the effect might be limited to that racial group.
To account for this, Kawahara and Osugi repeated the tests with models of four different racial appearances, East Asian, European, South Asian, and African, and compared responses from Japanese and U.S. participants. The results confirmed that Japanese participants consistently found bowing more attractive, no matter the model's race. U.S. participants still showed little response to the bowing gesture, and both groups reacted to differences in physical attractiveness as expected.
The researchers concluded that cultural background shapes how people interpret social gestures like bowing.
