Judgment of Faces. In a psychological study linking a person’s attitude with his or her perception of human faces, 165 subjects were asked to judge the attributes of each of two unknown faces.

It was proven that manipulated attitude significantly influences the judgment of facial dimensions that are evaluatively loaded (e.g., smiling or frowning mouth).
