How to look younger without plastic surgery

05.01.2011
Psychologists of Jena University show systematic change in the perception of faces

How to look younger without plastic surgery? Psychologists of the Jena University (Germany) have a simple solution to this question: Those who want to look younger should surround themselves with older people. 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. However when adaptor face and test faces show people of the same sex the after-effects of age perception are even stronger: this is the study's second result. 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 of the 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 In a second so far unpublished study elderly people were being asked to give their estimations.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.“

The founder of the “Playboy“ magazine might be surprised by these findings of the Jena scientists. Because he prefers to surround himself with young women, not knowing that they make him look much older. So Hugh Hefner should surround himself with elderly gentlemen instead of perhaps thinking of plastic surgery.

The Jena psychologists have published their scientific findings in the scientific journal “Vision Research“: Stefan R. Schweinberger, Romi Zäske, Christian Walther, Jessika Golle, Gyula Kovács, Holger Wiese: Young without plastic surgery: Perceptual adaptation to the age of female and male faces.“

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
