Psychologist Drew Walker believes that "ordinary faces look more attractive, probably because the unattractive features are automatically averaged." Psychologists believe that this is because people have a general impression of the looks of members in the group. Some people may not like it at first sight, but it is not so conspicuous in a group, because people's attention may average to each member, not to one person. In order to test the cheerleading effect, the researchers recruited 130 college students to carry out five experiments, and presented their group photos and personal photos to the subjects in a sequential and random way, so that the subjects could watch and evaluate the attractiveness of the characters in the photos. The results show that whether the photos are male or female, overall, people's attractiveness score in the group will be about 2% higher than that when they appear alone. Walker and Vul suspect that this average facial attraction and our tendency to treat a group of objects as a whole may support the idea of "cheerleading effect". So they found more than 130 college students and did five groups of experiments to verify them. In the first two experiments, they selected 65,438+000 photos of boys or girls, each with three different boys or girls. Sometimes they are presented in the form of photos, sometimes they appear independently, and the subjects must judge their attractiveness. The order in which the same face appears alone or first in a group photo is random, and each subject will always judge the attractiveness of 300 girls (experiment 1) or boys (experiment 2) when they appear in a group photo. The results show that there are great differences between the subjects whether they are boys or girls in the photo, but overall, the attractiveness score of people in the group photo is in Experiment 4. Walker and Vul want to try to see if there will be similar results if they just put their faces together instead of taking a group photo. They isolated each face in the experiment 1 and compared whether their attractiveness changed when they appeared alone or randomly placed with three other people, eight people and fifteen people. The results show that the personal attraction score when multiple faces appear together is still higher than that when one face appears alone.
