Gaetano Kanizsa

Gaetano Kanizsa was an Italian psychologist known for his work in visual perception. He studied how the brain interprets images and recognizes shapes, even when they are not explicitly drawn. Kanizsa created optical illusions, such as the "Kanizsa Triangle," where the mind perceives a shape that isn't actually outlined, demonstrating how our visual system fills in missing information. His research helped deepen understanding of how we perceive edges, contours, and whole objects, emphasizing that perception involves active interpretation by our brains, not just passive reception of visual data.
