What Do You See: A Fish or a Plane? The Left-Brain vs. Right-Brain Debate

Ambiguous images are designed to let your brain interpret visual information in more than one way. In this case, the picture can appear to be either a fish or a plane depending on how your visual system organizes shapes and outlines. Neither interpretation is more correct — they simply highlight different ways the brain can process the same image.

If you see a fish first, your perception may be focusing on smaller, enclosed shapes. This can happen when the brain emphasizes fine details and local patterns. It doesn’t mean you’re naturally more analytical — it just reflects which features your brain locked onto first.

If you see a plane, your brain may be grouping larger contours and imagining a broader structure. This happens when the brain relies more on global patterns. Again, this isn’t linked to creativity or any personality trait; it’s simply a momentary processing preference.

Many people associate these differences with the idea of being “left-brained” or “right-brained.” The popular belief is that left-brained people are logical and right-brained people are creative. While this idea is appealing, neuroscience shows it isn’t accurate. Both hemispheres work together on nearly all tasks, from math to music.

When you view an ambiguous image, several regions collaborate. The visual cortex handles the raw shapes and edges. The parietal and frontal areas help interpret those shapes and match them to familiar forms. Your brain constantly compares what you see to its internal library of stored images.

This is why your perception can switch if you stare longer. The brain updates its interpretation as it gathers more information, allowing different patterns to take shape.

These types of images are enjoyable because they offer insight into how our minds work — not who we are. They remind us that perception is flexible, and that intelligence, creativity, and reasoning rely on both sides of the brain working together.
