Which circle is bigger

It is effect of the surrounding blue circles that makes one pink circle look larger than the other. A Lenstore representative explained that the optical illusion pictures play tricks on our brains.

Illusions are also greatly impacted by colour, for example, changing the background or lighting is one of the most commonly used techniques in optical illusions, whilst the use of contrasting colours can even give the illusion of motion. Further studies argue that women are better at solving optical illusions than men due to colour blindness. Men have a colour blindness rate of approximately 8 per cent in comparison to women at 3 per cent.

Another viral optical illusion asks: can you find the cat? In this image, shared on Twitter by RASpoonie, users are baffled as to what makes the cat so hidden. At first, all you can see is dozens of owls all starting back from the picture with yellow beady eyes. However, perseverance pays off with this one, because the cat is definitely in there. If you look to the right of the picture towards the top middle, it is there. Answer The circle with a circumference of 30 feet is bigger. A procedural justification involves separately setting the formulas for area and circumference both equal to 30 and solving for the radius.

Therefore, a growing circle would reach an area of 30 square units before reaching a circumference of 30 units, so the circle with a circumference of 30 units would be bigger.

Schwarzkopf suggests that this is because the circuits in the visual cortex responsible for the illusion are the same size in everyone, but cover a greater proportion of a smaller visual cortex, causing a stronger effect.

The team also found that people with a smaller visual cortex tended to have bigger brains overall, though it is not clear why. By Jessica Hamzelou Which orange circle looks bigger? Image: Samuel Schwarzkopf Are the orange circles in this picture right different sizes?
