Viral Optical Illusion: These optical illusion quizzes are among the most popular brain exercises online, having attracted many people on various social networking sites each week. These visual tests are entertaining but also provide a brief exercise for your mind. Cognitive psychologists reveal that a human mind can process visual stimuli in as little as 13 milliseconds, but it also takes mental shortcuts that could result in bizarre errors and this is precisely what makes the recent viral challenge quite popular.
The challenge requires players to find the well-hidden number ‘46’ that is buried amongst numerous ‘64’s in just ten seconds. The puzzle might seem easy at first glance however, due to the similar formation of digits, it proves to be much harder. Only people with excellent observational abilities and concentration will be able to complete it successfully.
Find the Odd One Out in the Given Image
On initial inspection, all numbers in the square seem alike. But there is a lone number 46 that lies within this repetition of 64 numbers. The trick here is in overcoming the mental propensity for treating repetitions as identical while most people scan the square randomly with their eyes, one should try scanning it in horizontal or vertical lines. It is essential to focus on the placement of the digits rather than the appearance of the whole square.
How Alert Are You?
Think you have sharp eyesight? Start your stopwatch for 10 seconds and trying to find the hidden 46.
According to the researchers, people perceive visual patterns very quickly however, after excessive repetitions, our brain tends to ignore small details. It was estimated that up to 80% of information, which is received by our brain visually, is processed unconsciously.
If you managed to find the hidden figure during the limited time period, then your visual attention and concentration skills are rather high.
Visual IQ Test
While this puzzle is not an official IQ examination, it does measure several important cognitive skills, including:
- Visual discrimination
- Pattern recognition
- Selective attention
- Processing speed
- Concentration under pressure
According to neuroscience research, visual puzzles might be useful for improving one’s attention, memory and problem-solving skills. Just dedicating 10-15 minutes to brain exercises a few times a week can have a positive effect on the ability to think flexibly.
Answer Out!
Still searching?
Here is a tip for you: Concentrate on the right side of the grid rather than search randomly. In case you still cannot find it, the number 46 that is concealed in the grid can be seen in the 8th row and 6th column from the left side. In case you managed to find it in 10 seconds or less, then good job!
Why Do Optical Illusions Fool Us?
It is through optical illusions that the mind prioritizes efficiency over perfection. Instead of looking at every detail separately, our brains make predictions on what should be seen based on other patterns present. In cases where there are dozens of 64s, the brain makes predictions based on previous experience and disregards small differences between patterns. This cognitive distortion is called pattern recognition bias and thanks to it, we are able to comprehend partially written words, recognize faces instantly, and quickly perceive images that we come across in our daily lives.
That delicate balance between speed and accuracy is precisely what makes optical illusion challenges so fascinating and addictive.
