The story of the word

Adam Zeman and colleagues at Exeter named the condition in 2015, reaching back past modern psychology to Aristotle, for whom φαντασία was the faculty that produces images in the mind. Francis Galton had already stumbled on it in 1880 when he asked scientists to picture their breakfast table and some of them said, flatly, that they could not. The same root gives phantom and fantasy, both of them things that appear without being there.
