Most people can picture images in their heads - the look of an apple, the appearance of their kitchen or the smile of their best friend - but not everyone can.
Those who cannot visualise anything in their mind’s eye are probably among 1% of people with extreme aphantasia, according to a review of studies on the phenomenon.
They are also less likely to recognise faces, remember the sound of a piece of music or the feel of sandpaper, and more likely to work in science, maths or computing.
And up to 6% of people may experience some degree of aphantasia.
It is not a disorder and does not imply a lack of imagination but can have subtle effects on everyday life, says Prof Adam Zeman, honorary professor of neurology at the University of Exeter, who came up with the term nearly 10 years ago.
I’m pretty sure I have aphantasia. My mom, on the other hand, is an artist with very powerful imagination. She would often tell me how she sees something she’s imagining and I never really knew what she meant. I just assumed that it’s kinda a figure of speech. Only when I first read about aphantasia I realized that it probably really works completely differently for her.
I would like to know whether aphantasia has any practical impact on one’s life. For example, I had this suspicion that differences in my “mental image processing pipeline” might be a factor in my terrible driving skills. Quick visual assessment of the traffic situation, at an intersection for instance, is very hard for me. This is just me making stuff up though, no idea if it makes any sense. In fact, I think I’m going to research this topic and look for some papers now!
