Passage Two.
Back in the 1870s, Charles Darwin s cousin Francis Galton wanted to define the face of a criminal. He assembled a set of samples by lining them up on a single photographic plate. The surprise: everybody liked the villain (流氓), including Galton himself.
He reasoned that the villainous irregularities he supposed belonged to criminal faces had disappeared in the averaging process. In the next century, scientists began to show reliably that faces combine digitally on computers were likable--more so than the individual faces from which they were composed. Although people clearly admire the long legs of Brazilian model Ana Hickmann or Dolly Parton s breasts, in general humans like averages.
Last week researchers confirmed that humans judge real faces by their differences or similarities from a norm. But they also found that the norm can change quickly. When researchers showed 164 people a set of 100 computer generated faces representing a slow transition from male to female--and from Japanese to Spanish--it turned out that the test subjects idea of what constituted an "average" face shifted depending on the first face they saw. When they were flashed a super-masculine face first, more faces on the spectrum impressed them, by contrast, as female. The masculine faces had, in effect, set a standard. From then on, other faces had to be more masculine in order to rate as belonging to the gender. The study noted a similar shift using a scale of faces moving from surprise to disgust.
The authors of the study, who published their results last week in the journal Nature, conclude that in real life we also quickly change our perception of the midpoint--what s normal-depending on what we see. We may not be aware that our judgment has changed. we simply see differently, says Michael Webster, a psychologist at the University of Nevada in Rena.
