Among the findings, mind-blindness was associated with difficulty remembering the past, such as a special event.

“Most of us will remember these events by ‘picturing’ the scene in our mind’s eye,” says Dawes, “adding colour, shape, shadow, tone and movement to the images, almost like they are being projected onto a screen in our minds.”

“We might see the blinding white of the clouds, the soft green of the grass, the movement of shadows across a tree branch.”

People with aphantasia lack this rich sensory detail, so they can recall things that happened, but don’t see it in their mind’s eye.
