The other theory is that it might be related to withdrawal symptoms from staring at the colours - with the brain now associated vertical lines with green, and horizontal lines as red. The McCollough effect is a clever, if slightly mean trick, to play on the brain because it taps into processes that are usually very important and useful, said Dr georgina powell, a research associate in the School of Psychology at Cardiff University. She favours the first theory to explain the effect. Think about going from a dark room into bright sunlight - initially we are blinded by the light but the brain quickly adjusts so we can see things more clearly. In the McCollough effect, the brain thinks that the pairing of the colours and the lines must be some sort of internal error. It makes this mistake because it is very unnatural to be exposed to such patterns for so long and so it attributes them to a problem in visual system not something real in the world.
Fear not, though; if you want to reverse the effect, you simply need to stare at the original coloured images again for half the time you originally looked at them, but rotate them 90 degrees aftrekbaar counter clockwise. As Mr Scott explains in his video, this trick isnt taking place in the retinas of your eyes. Instead, he says, the McCollough effect, for some reason, works in the level of the brain. He continued: The McCollough effect is a very rare thing. Its a real image that can lock into your brain, change the way it works, and stick around for a good while. It is a real, headache-inducing sensation, and that is something quite scary that you might not have known.'. The McCollough bears some similarities to the infamous dress (shown) that caused a stir on the Internet in February, with some people seeing it as white and gold, while others saw it as black and blue. The exact reason the trick works, however, is not completely understood. There are three main theories. The first is that staring at the coloured images causes your visual cortex in your brain to see colour next to particular straight edges. Another theory is that your brain is error correcting after staring at the black and white image for so long, and compensates by adding colour where it might not have been before.
The effect will be more pronounced if you spent longer on step two. Youll notice that even after a few minutes, the effect is still noticeable. The effect can actually remain for up to three and a half months, and may be noticeable on other horizontal and straight lines aside from the ones in the grid. To reverse the effect, you simply need to stare at the original inducion images again, but rotated 90 degrees counter clockwise, for half the time you originally stared at them. The rotated image is shown below. The longer you perform the initial trick, anywhere up to 15 minutes in total, the more pronounced the effect will. But unlike many optical illusions, the most bizarre thing about this one is that, even after several minutes, the effect is still noticeable. In fact, reports by Dr McCollough suggest that it can last up to three and a half months.
