Kanizsa square

Another example of the brain ‘adding’ information is the Kaniza square illusion. For example, in the image below, people often perceive a black square on top of four white circles. Instead, this image could be easily seen as four white ‘pacman’ shapes. Yet, we are more likely to perceive the square shape. This effect is known as the perception of illusory contours, and is something of interest throughout this project.
