Interview with Akiyoshi Kitaoka

73 min • 3 mars 2025

In this episode I relate a written interview I had with Dr. Akiyoshi Kitaoka, a Professor of Psychology based in Japan. He does research on visual perception and makes visual illusions. His work embodies a fascinating combination of creative and technical aspects. I’d recommend viewing this episode on YouTube rather than as an audio podcast as there are many visual demonstrations.
