History of Aphantasia
Aphantasia, the inability to voluntarily form mental images, was first described by Francis Galton in 1880 but largely remained unstudied until 2015, when Professor Adam Zeman of the University of Exeter coined the term and began his research, bringing renewed scientific and public attention to this fascinating aspect of human cognition. The concept traces back to Aristotle's "phantasia" from 340 BC, establishing a rich historical foundation for understanding individual differences in mental imagery.
