Study on the degree of memory of facial contents

The sense of incongruity experienced by people is the feeling that "I understand something is different, but cannot explain it in concrete terms." This sense of incongruity may trigger the detection of fake works, such as paintings. In this paper, we focused on the size of the face of an unconsciously memorized person to clarify the relationship between unconscious memory and incongruity. Using the size as a parameter, subjective evaluation experiments were carried out by displaying the three contents of real persons, animated characters, and monsters in 2D (two-dimensional display) and 3D (stereoscopic display).
