Islamabad, Jan 7:
How to look younger without plastic surgery? Psychologists of the Jena
University (Germany) have a simple solution: Those who want to look younger
should surround themselves with older people. That's because when viewing a
30-year-old, we estimate his age to be much younger if we have previously been
perceiving faces of older people.
"People are actually quite good at
guessing the age of the person next to them," Dr. Holger Wiese says. The
psychologist of the Jena University is responsible for one of six research
projects in the DFG-sponsored research unit "Person Perception" lead by
Professor Dr. Stefan R. Schweinberger.
In the experiment the Jena
psychologists were able to prove that the volunteer testers were systematically
wrong at estimating other people's age after having adapted to the faces of
people of a specific age group by intensely looking at them. If many faces of
elderly people were shown on the computer first, followed by the test face of a
middle aged person, the test candidates estimated this person as substantially
younger. After studying younger faces the middle aged test face was estimated as
being substantially older.
"These effects occur independently of the
viewer's age and sex," Schweinberger says. When faces used for adaptation and
test faces show people of the same sex the after-effects of age perception are
even stronger. In other words: the perception of age and sex in faces is not a
completely independent process.
These results may hardly surprise
non-experts but they contradict various previous opinions of experts.
The
scientists at Jena University used the most modern digital image editing
techniques and a data bank of faces without any make-up and with distracting
elements having been touched up. The first people partaking in the experiment
were students. In a second so far unpublished study elderly people were being
asked to give their estimations.
Stefan Schweinberger sums up the result
of their findings: "We are able to change the subjective perception of a face."
Nobody knows though how long this effect lasts. Holger Wiese adds: "The age of
the person next to you is one of the most important characteristics for our
perception of other people. This leads to exciting crossovers into other areas
of scientists who are dealing with the interactions of social
groups."
