Only 1 per cent of people can find the celeb in this optical illusion

is sure to leave some people confused as they try to spot a hidden celebrity.

The picture, which shows rows and rows of black dots on a white background reveals The Sun reports that only one per cent of people can actually spot the celebrity in the clue. That figure might be in some dispute, but the figure can be tricky to spot for some.

If you are having trouble in the image, then take note of the following clues: it is a famous pop star; the star died in 2009; finding the image should be a “thriller” of an experience. If you are still unsure, try moving further back from the image and it should become clearer.

For those still stuck, we can reveal the image is that of 'Smooth Criminal' and 'Man in the ' singer Michael Jackson. In the other images above you should be able to see a panda on the left. On the right is music legend John Lennon.

Psychologist and human perception expert at Goldsmiths University in London, Dr Hustav Kahn, told The Sun that the puzzle plays on our brain’s ability to process information.

He said: “Our eyes encode vast amounts of messy sensory information, and our brain uses clever tricks to disambiguate this information to try and make sense of what it is we are looking at… What you see is results of vast amounts of neural computation, mixed with a bit of guesswork.

"For example, when you stare at a bunch of trees, you can interpret this as a forest, or a tree. What you are seeing depends on which aspect of the scene you are focusing on."

Professor Fiona Macpherson, an expert at the University of Glasgow's Illusion Index, explained to the newspaper that moving further away from the image makes it easier for us to see because of the spatial frequency in the image. Referring to the image of the panda above, she said: “The closer the image is to you the lower the spatial frequency and the further away it is the higher the spatial frequency.”

Brainteasers aren't just a good way to pass the time as the days become darker and colder, they are also good for your cognitive health. Completing challenging puzzles, brainteasers and optical illusions may help improve your cognitive function, boost productiveness and memory. Aaron Seitz, PhD., professor of psychology and director of the Brain Game Centre at the University of California in Riverside told Real Simple: "Studies show that staying mentally fit is important for long-term cognitive health, but the difficulty is figuring out exactly how to do it.” If you aren’t sure where some of the clues are, then don’t worry. We have the answers for you to view below.

He added that some games work differently for people and finding your own challenge might be the best thing to do. "If you think about diet and exercise routines, some things work better for some people than others, and the same is true with brain games,” he said. It is not clear if brain games and teasers really improve your cognitive abilities, but they can help to keep you relaxed and fresh, leading to indirect benefits.

Nicole M. Avena, PhD, assistant professor of neuroscience at the Mount Sinai School of Medicine in New York City and visiting professor of health psychology at Princeton University said: “While some studies show that brain training games are not effective, the recollection and work that the brain does during these games keeps your mind fresh and alert… Brain functions that you practise during these games—and the repetition of them—can help improve response time and sharpness.”
