Answer: One shade of green and one shade of red! Likewise, only one shade of green is present throughout the image.

Answer: There are no black dots. Answer: All of the lines are straight. Answer: There are no triangles. Take a very close look at the 2 vertical lines. Do you think one line is longer than the other? Answer: They are the same size! Hard to believe; get out your ruler to measure the lines and see for yourself!

Each participant completed the experiment and was run through the brain scan 10 times. That visual system in the back of the brain? Each animation produces a different pattern of activation in the visual cortex. Then why do we perceive them as being the same? That is: The front of the brain thinks both animations are traveling in a diagonal direction. To be sure: Vision is a vastly complex system involving around 30 areas of the brain.

You can see it for yourself. The lesson: The stories our brains tell us about reality are extremely compelling, even when they are wrong. Why are we seeing a story about the world — a story — and not the real deal? Think about what it takes to perceive something move, like the objects in the above animations.

From there, the signal travels forward through our brains, constructing what we see and creating our perception of it. This process just takes time.

So the brain predicts the path of motion before it happens. It tells us a story about where the object is heading, and this story becomes our reality. It happens all the time. See for yourself. The red dot is moving across the screen, and the green dot flashes exactly when the red dot and green dot are in perfect vertical alignment.

The red dot always seems a little bit farther ahead. This is our brain predicting the path of its motion, telling us a story about where it ought to be and not where it is.

It helps us overcome these delays and see things The actual sensory information, he explains, just serves as error correction. Our brains like to predict as much as possible, then use our senses to course-correct when the predictions go wrong.

This is true not only for our perception of motion but also for so much of our conscious experience. The brain tells us a story about the motion of objects. It also tells us stories about more complicated aspects of our visual world, like color.

For some meta-insight, look at the illusion below from Japanese psychologist and artist Akiyoshi Kitaoka. You can observe your own brain, in real time, change its guess about the color of the moving square. Keep in mind that the physical color of the square is not changing. You might look at this illusion and feel like your brain is broken I did when I first saw it. It is not. A moving square appears to change in color, though the color is constant.

Color is an inference we make, and it serves a purpose to make meaningful decisions about objects in the world. Red may not appear red when bathed in blue light.

Our brains try to account for this. When we think an object is being bathed in blue light, we can filter out that blue light intuitively. Sometimes those guesses are wrong, and sometimes we make different assumptions from others. Neuroscientists have some intriguing new insights into why our perceptions can diverge from one another.
