**5.3 Comparing face processing mechanisms between Chinese and Korean**

Here, we focused on the role of script or spoken form of one language in face processing. Previous studies have shown that too many differences in face processing existed between East Asian and Western cultures that prevent attribution of sole factor to the cultural difference in face processing. Therefore, one way is to investigate the role of two disparate script systems in face processing in East Asian culture. As we know, respecting the East Asian culture are people from China, Japan, and Korea, and so on. Notably, one possibility is to explore the relationship between script systems and face processing by recruiting subjects with different script systems in East Asia, which lies in an identical culture. A typical way to achieve this is to compare individuals from China and South Korea. One unique feature of this comparison is that the pronunciation of Korean resembles that of an alphabetic language, however, the visual characteristics are closer to Chinese [65]. Therefore, employing the identical experimental task, one could morph the Chinese and Korean faces. By doing so, one could eliminate the impact of the amount of exposure to face processing, and explain face processing by the weights of speech.
