Students at worldwide universities are going crazy over an image that requires keen observational abilities and a high IQ.
In particular, two psychology professors from Flinders University in Australia have created a sketch that, at first glance, appears to show an elderly woman. But there is also a hint of a young woman in the illustration.
This image is used to “unveil” one’s age in addition to testing IQ. According to research, people over the age of 32 first notice the elderly woman before recognizing the young woman. On the other hand, people under the age of 32 notice the young woman first.
Here’s a tip if you’re having trouble finding the young woman: her left cheek is in profile, and the elderly woman’s nose really shapes her chin.
