Seeing Through Circles: The Ebbinghaus Illusion and the Brain
About this episode
A deep dive into one of psychology’s classic visual tricks—the Ebbinghaus illusion. We explore how the brain constructs size, what it reveals about perception and action pathways, and how genetics, development, and culture shape our susceptibility. From early debates about vision to cross-cultural findings that emerge in childhood, this episode shows why seeing isn’t just about photons—it's about the brain guiding behavior and interpretation.
