- When we think about optical illusions, we're usually thinking of a subset of illusions called cognitive illusions. These are illusions that - unlike a mirage, for instance - interact with our unconscious assumptions about the world and our perceptual processing.

Oct 19, 2023 · There are three types of optical illusions, as noted by British Psychologist Richard Gregory. These are physical, physiological and cognitive illusions. Physical illusions are often distortions of scale, such as when a huge mountain appears closer in clear weather, but is actually quite far away.

Congratulations if you kept up with the jellybean, but the chances are you might have missed the fifth hand, the fox and the change in colour of the cups. So what's going on? This illusion shows we don't pay attention to everything that's going on, even in simple scenes, Dr Spehar says. "As you are tracking the movement of the cups, your attentiona...
This is a static image. Or is it? The image appears to move, but if you stare at the central point, it stops moving. So what's going on? Known as rotating snakes, this illusion triggers receptors in your retina that are responsible for detecting movement in your peripheral vision. Dr Spehar says we don't exactly know how this illusion works, but it...
This is just an ordinary room. Or is it? Instead of being shaped like a box, the back wall of an Ames room is on an angle. In this example from Catalyst, the right-hand corner is closer to us than the left-hand corner, so it distorts our view of Lily. When she stands on the right she looks like a giant, but when she moves to the left she appears to...
The 3D Schröder staircase, created by Japanese mathematician Kokichi Sugihara, was the winner of last year's Best Illusion of the Yearcontest. "I made this optical illusion as an experimental material to examine the brain behaviour that, when seeing a 2D picture mixed with a real 3D object, perceives the picture part as 3D too," Dr Sugihara says on...
Like the Necker Cube, this classic illusion is an ambiguous figure. You can only see one woman at a time. Which do you see? Ambiguous figures test what's known as figure-ground perception. You can either see the figure or the ground, but never both at the same time. "If you see a younger woman, you can't see the old woman, and if you see the old wo...
The ability to see faces, or other objects, in random patterns is known as pareidolia. Look carefully and you'll see faces all around us; in trees, rocks, clouds, the Moon and dodgy photos of paranormal phenomena on the internet. Pareidolia is an unusual illusion in the sense that the brain is creating something from a lot of noise, says psychologi...
In 2015, a badly lit photo of a sparkly striped dress took the internet by storm. "It caused such disagreement about what a very simple stimulus actually showed," Dr Cropper says. Were the stripes blue and black or white and gold? "If you see that dress in real life there is no question about what the colour it is," Dr Cropper says. "It's only beca...

It’s important to emphasize that we’re as prone to cognitive illusions as we are to optical illusions. We all have remnants of them—yes, even our chief residents. If this ubiquity is not emphasized to patients, many are otherwise apt to criticizing themselves for succumbing to them.

Other optical illusions are cognitive. Cognitive illusions, such as ambiguous , distorting and paradox illusions, occur when our brains automatically make assumptions based on the information sent from the eyes.
Optical illusions can be categorized into different types, including literal illusions, physiological illusions, and cognitive illusions, each stemming from different processes in the brain.
