Ella Rhodes, journalist for The Psychologist magazine, delves into the growing body of research exploring aphantasia – a condition she has personal experience of. While most people can see images formed in their minds people with aphantasia draw a blank, what might this mean for autobiographical memory, face perception and imagination?

Our guests, in order of appearance, are: Zoe Pounder at the University of Westminster and Professor Adam Zeman at the University of Exeter.
