Have you ever seen a robot that looks almost human, but something feels a bit off? Did it make you feel unsettled, and maybe a bit creeped out? Dr. Yulia Vaitonytė joins us to discuss her research on this phenomenon of the uncanny valley. She unpacks the brain and perceptual cues behind this eeriness, and tells us why certain kinds of imperfections might actually help robots appear more real. Beth & Ava play a game to see if they can recognize real faces from artificially generated ones.
