In social psychology, this effect is sometimes called the familiarity principle. The effect has been demonstrated with many kinds of things, including words, Chinese characters, paintings, pictures of faces, geometric figures, and sounds. In studies of interpersonal attraction, the more often people see a person, the more pleasing and likable they find that person.⁠ ⁠ ⁠ ⁠ ⁠ #psychology #attraction #biology #evolutionary #science
