Greetings Card : Ehrenstein illusion
Cards from Science Photo Library
Ehrenstein illusion
Ehrenstein illusion - illusory contours forming circles. Created in 1954 by the psychologist Walter Ehrenstein, this illusion demonstrates the false perception of areas of increased brightness. Crosses are apparently joined by bright white circles. In fact no such circles exist. It is still a source of some debate whether this is due to the brains attempts to interpolate fragmentary information and infer boundaries, or to the visual cortex pre- processing information before it reaches the conscious parts of the brain

EDITORS COMMENTS
This print showcases the Ehrenstein illusion, a mesmerizing optical trick that challenges our perception of reality. Created in 1954 by psychologist Walter Ehrenstein, this illusion reveals the brain's remarkable ability to create illusory contours forming circles. At first glance, crosses appear to be connected by bright white circles, but upon closer inspection, we realize that no such circles actually exist. The Ehrenstein illusion raises intriguing questions about how our brains process visual information. Some argue that it is a result of the brain's attempt to fill in missing details and infer boundaries from fragmentary data. Others propose that the visual cortex pre-processes information before reaching conscious awareness. As we delve into the depths of this image, we are reminded of the complexity and ambiguity inherent in human vision. The interplay between brightness and darkness creates an ambiguous boundary where our perception becomes deceived by these illusory contours. It serves as a testament to both the wonders and limitations of our visual system. This thought-provoking photograph not only captivates us with its circular trickery but also invites us to ponder on the mysteries lying within neuroscience and psychology. With every gaze at this image, we are reminded of how easily our perceptions can be manipulated and challenged—a reminder that appearances can indeed deceive us.
