This is a test for mental age.
The first time I see a girl, the mental age is younger than the actual biological age.
At first sight, the old woman is older than her actual physical age.
Both mental age and age can be regarded as a pair of "yin and yang" that are independent of each other
Yin and Yang is a way of thinking, and everything can be divided into Yin and Yang, as long as it is within a category.
Relative to the "relative aspect", we can judge "yin" or "yang", that is to say, Tan yin and yang, there must be two premises: first, what category should be set;The second is to talk about the relative-
A team of scientists from Flinders University and the University of South Australia in Australia concluded that the perception of the painting was largely dependent on the age of the person. This conclusion was published in the British journal Scientific Reports.
The peculiarity of this picture is that one of the heads depicts two women: a young woman** with her head slightly facing away from the viewer, and the viewer can see the tip of her nose, eyelashes, ears, neck, and necklace) and an elderly woman (a profile portrait of her hooked nose, eyes, mouth, and chin).
The researchers asked them to ** this image and asked them what they saw first: an animal or a humanIf it's a person, is it male or female?If it's a woman, how old is she?
The results of the test showed that viewers younger than 30 years old often saw young women, and that the younger the viewer, the younger the woman in the painting. Viewers older than 30 mostly see older women.
