About :

In this video, Ralph Caspers explores the following questions: How well does our perception work? Can we be sure that what we see, hear or feel is reality? Or is the world around us really just a simulation of our brain? Our sensory organs are constantly reporting information to the brain. The brain is constantly busy processing the stimuli and considering what to do next. But how reliable is our perception? How easily can we be deceived? Ralph shows this using some astonishing perception experiments. One reason why our perception sometimes deceives us is that our brain tries to be as efficient as possible and predict as much as possible. You can see the consequences of this in the video!
