Скачать или смотреть Demo Day: Floating Dog Amodal Completion.

This video demonstrates the illusions that can be created by manipulating the brains ability to complete objects amodally. Amodal completion is the brains ability to recognize and piece together whole objects even when they are partially obscured by another object. This illusion uses amodal completion by obscuring the space between the individual dogs including the front half of one dog and the back half of the other. Amodal completion tells the brain that the object behind the obstruction is a long dog because it pieces together the front and back halves of 2 different dogs. The gestalt principle of good continuation is also at play here as the dogs that have similar body width complete more effectively behind the obstruction. I drew all of the dogs in the same alignment to make the illusion work but the differing widths and tapers of the dogs' bodies makes some long dogs complete amodally better than others.
