Greetings Card : Circle in a square illusion
Cards from Science Photo Library
Circle in a square illusion
Circle in a square illusion. The two red circles in the image are the same size. However, the one inside a blue square looks larger than the one enclosing a blue square. This is similar to the Delboeuf illusion and is a demonstration of assimilation - the effect whereby the perceived difference between neighbouring objects is reduced. So the brain treats each circle as being closer in size to its square than it actually is, leading to the apparent discrepancy

EDITORS COMMENTS
This print showcases the intriguing "Circle in a Square Illusion". At first glance, it may seem that the two red circles differ in size. However, upon closer examination, we discover that they are actually identical. The optical trickery lies in our brain's perception and assimilation of neighboring objects. Similar to the Delboeuf illusion, this image demonstrates how our visual system can be easily deceived. The circle enclosed within a blue square appears larger than its counterpart surrounded by a smaller blue square. This phenomenon is known as assimilation - where our brain perceives objects as being closer in size to their surrounding shapes than they truly are. The complexity of human vision and psychology comes into play here. Our brains automatically make assumptions about relative sizes based on contextual cues, leading to an apparent discrepancy between the two circles. This mesmerizing visual illusion not only challenges our perception but also sheds light on the fascinating field of neuroscience and its study of illusions. It serves as a reminder that what we see is not always what it seems, highlighting the ambiguous nature of human vision. Science Photo Library presents this thought-provoking image capturing both artistry and scientific intrigue without any commercial intent.
