The Unexpected Optical Illusion Hidden in a Stack of Chairs

  The Unexpected Optical Illusion Hidden in a Stack of Chairs A scientist in the UK found a stack of classroom chairs that seemed to bend the laws of physics.

One day, the rotating dots may even be used as a tool to help diagnose autism. Watch the dots spin for a moment. Nearly everyone sees a spinning Professor Burr went a step further - he demonstrated the traits revealed by the illusion seemed to be mirrored in people's personalities and thinking styles.

AN OPTICAL illusion can reveal how dirty your mind is depending on what you see . This optical illusion might reveal a lot about your personality.

How you see this simple optical illusion, and more importantly how your brain sees it, could reveal a lot about you.

One day, the rotating dots may even be used as a tool to help diagnose autism.

Watch the dots spin for a moment. Nearly everyone sees a spinning hollow cylinder, black on one side and white on the other, randomly changing direction.

But not everyone’s brain is processing the image in the same way.

Of course, there is no cylinder per se – just 300 dots moving from side to side, switching from black to white.

Optical illusions can be tricky. Take a look at these photos, go with your gut reaction and think of the first thing you see when you look at each image. You might just learn a little something about yourself in the process.

But this optical illusion claims to reveal a lot about a person’s personality. What did you see ? This optical illusion comes after an optical illusion tested how dirty a person’a mind was.

The typical brain takes in the big picture, ignoring the details.

But to the brains of people with high levels of attention to detail, it’s just dots.

When you look at this , do you see a pair of plastic-looking legs , or legs covered in paint? Your answer may be indicative of how you solve problems. Optical illusions -turned-personality test? It’s a very interesting concept, indeed. Whether you take a lot away from this or not, you ’ve got to admit—they’re

David Burr and his collaborators have been showing this illusion to university students in Pisa and Florence, in Italy, over the past year. In a clever experiment, they have tracked the size of the students’ pupils with an infrared camera as they watch the cylinder spin.

"Everybody reports the spontaneous and unpredictable changes in the cylinder’s direction," says Professor Burr, who now works at the University of Sydney. "But not everyone perceives the figure in the same way."

Pupils contract and expand, like the iris of a camera, to control how much light hits the retina.

The overall darkness of the cylinder does not change. If you’re paying attention to the whole picture, your pupil won't move.

Samsung Galaxy Note 9 to feature an in-screen fingerprint reader

  Samsung Galaxy Note 9 to feature an in-screen fingerprint reader With the Galaxy S9 now fully unveiled at Mobile World Congress 2018, the mobile industry is now already looking forward to Samsung's next flagship phone, the Galaxy Note 9 .What's more, information about the new Note's current status has already started leaking, with a particularly juicy leak pointing towards a fingerprint reader in the display.

But if you’re focused on the dots, your pupils will move – contracting sharply when the bright white ‘side’ of the cylinder is in front, expanding when black is in front. This is what Professor Burr was looking for with his camera.

The brains of these responders are focusing their attention on the individual surfaces of the cylinder, rather than the cylinder as a whole. Even if they don’t ‘see’ it, their brain is focused on detail, rather than the bigger picture.

Professor Burr went a step further - he demonstrated the traits revealed by the illusion seemed to be mirrored in people's personalities and thinking styles.

As part of Professor Burr's study, published this week in eLife, subjects also took a self-administered test of autistic traits. Those who saw the dots, not the big picture, tended to score much higher – which makes sense, the professor believes, because autism is characterised by extreme attention to detail.

If the study can be repeated using more people – Professor Burr tested only 50 – and on people diagnosed with autism, he thinks it might become a useful diagnosis tool for autism.

Dead Rat Found Inside Red Bull Can

  Dead Rat Found Inside Red Bull Can A video shared on social media shows the can being cut in half with a pair of scissors to reveal what appears to be a dead mouse in it. According to Josh Henley, he bought the energy drink can from a gas station Sunday night. The man said he drinks Red Bull energy drink all the time but had never experienced something like this."I don't know if it's factory or what but there's a dead rat in here," Henley said in the video as he opened the can. Henley reportedly said he didn't finish the drink when he opened it first.

And that helps others in determining, how your mind works. There's no right or wrong answer - you just have a way of seeing things. Here's an optical illusion which tests your brain and provides insight into your current relationship status.

Humans aren’t the only ones who sees optical illusions either. In this famous visual illusion , the square marked with an A looks a lot darker than B, right? This illusion , popularized by Italian psychologist Gaetano Kanizsa, reveals how we tend to seek closure in our visual perception.

Others aren’t convinced. “This is not a particularly strong study, it’s not even talking about an autistic population,” says Professor Cheryl Dissanayake, director of the Olga Tennison Autism Research Centre.

That said, people with autism do tend to excel at spotting fine details and pattern recognition while struggling to see the overall structure of something.

Savant capacities, such as exceptional drawing ability or solving a jigsaw puzzle with the pieces face-down, have also been linked to superior attention to detail.

Many scientists now believe that autism, characterised by impaired communication and social interaction, is in fact a symptom, with the underlying cause being extreme attention to detail.

"When we come out of the womb, humans perceive the world in a particular way. We focus on social information, such as faces and eyes," says Professor Andrew Whitehouse, chief research officer at the Autism Cooperative Research Centre.

"If we’re not perceiving the world in that typical way right from the get go, then of course our development will be different.

"There is a theory that kids aren’t necessarily ‘born’ with autism, they are born with subtle differences in the way they perceive the world. From that point of view, autism is a perfectly normal response to a different starting point in life."
