Impossible trident
Impossible trident. This uses the fact that a rectangular bar can be represented in 2 dimensions by 3 lines, whereas a cylinder requires 2. So we have 3 cylinders blending into 2 rectangular bars. The brain tries to identify the shapes but is left confused due to the ambiguities over to which part the edges belong. This object has been used to demonstrate that the visual system compares different regions through counting, since the first thing most people notice is that 2 prongs at the beginning change to 3 at the end

Ambiguous Illusory Impossible Object Neuroscience Panoramic Perception Psychology Shape Trick Vision Visual
EDITORS COMMENTS
This print showcases the enigmatic "Impossible Trident". The intricate design plays with our perception and challenges our understanding of shapes. At first glance, it appears to be a combination of three cylindrical objects seamlessly blending into two rectangular bars. The genius behind this illusion lies in the fact that our brain struggles to identify the true nature of these shapes due to their ambiguous edges. As we try to make sense of what we see, confusion sets in, leaving us perplexed by this illusory object. Psychologists and neuroscientists have used the Impossible Trident as a tool to study how our visual system processes information. It highlights that our brains rely on counting or comparing different regions when interpreting complex visuals. Interestingly, most people initially notice a transformation from two prongs at one end to three prongs at the other – an intriguing aspect that adds another layer of mystery. This panoramic photograph captures not only the trickery involved but also invites contemplation about human perception and its limitations. Science Photo Library has expertly captured this mind-bending image, offering viewers an opportunity for introspection into the fascinating world of visual illusions and neuroscience research.
