People Who Can't Picture Anything Are Rewriting the Science of Imagination
A new review in Consciousness and Cognition argues that the brain doesn't create mental images by running ordinary seeing backward through the primary visual cortex. Evidence from patients with damage to that region, who can still visualize, and from people with aphantasia, who cannot, points instead to a distributed network spanning frontal, temporal, and parietal areas. The authors, two of whom have aphantasia, propose that mental imagery is an emergent property of coordinated brain activity, not the product of a single region.
Asked what sits beside the television, they answer without hesitation, but "we experience these as an awareness of a set of spatial facts."

I’ve worked as a professional photographer for twenty years and I visualize absolutely zero with my eyes closed. It’s only recently that I learned of aphantasia. Even on most psychedelic journeys I don’t have closed eye visuals, NN-DMT being the consistent exception. Everything is more of just a “knowingness”.

Rather unfortunate if so, as aphantasia has been known about since Galton discovered it in 1880.

For anyone who doesn’t believe this is real, I recommend reading Thinking In Pictures. It’s a great book.
Explains 3 types of thinking that people use in their day-to-day: Linear verbal, schematic conceptual, and photo realistic.
It’s all a spectrum so you likely use all 3 to an extent.
Most people think linearly and sort of describe things in their mind that they’re trying to imagine. It’s a picture but not really.
Engineering types most commonly are strong in conceptual thinking. You can imagine complex systems and how they connect but it’s hard to describe and linearize this into words. You have to translate. Again it’s sort of an imagined picture but not really.
Then there is photo realistic where you see the thing in your mind. Almost as if you were seeing it for realzies with your eyes. Common with visual artists and some types of autism. Linearizing into words is almost impossible.
The book talks about the extreme opposite of aphantasia but it builds a good way of understanding these different qualia imo

Aphantasiac here, happy to discuss or answer any questions

It has been a lot of fun talking to those who are Aphantasiac. I am the complete opposite to the point where I think almost exclusively in imagery and when talking to folks I translate visuals to words on the fly. For a long time when people said that they saw black when they closed their eyes I assumed that meant that they choose to "see black". This is less about being able to see and more how we utilize that.
So whenever I chat with someone with is Aphantasiac being able to compare and contrast has been a treasure trove. Hobbies, careers, romance/relationships, what we like to read/watch, what we are good and bad at. Having our two extremes allow us to do rapid research see what is opposite and what isn't.
And then in the same way I will describe smells by how they look like they will describe stuff to me that I struggle grasping without visualizing it and that is a joy.

The article is only about the absence of mental images, but the same is true for all other senses as well. People might be able to recall or imagine images, sounds, smells, tastes, feels while being awake or not. And it can be in all permutations, tho, vision affected seems to be quite common.

I'm pretty sure I have this, for all senses, and I only just learned there's things other than iñner eye (which I only learned of a few months).
If people have an "inner taste" or "inner hearing", why bother eating a sweet or playing music?
> Asked what sits beside the television, they answer without hesitation, but “we experience these as an awareness of a set of spatial facts.”
This helps me understand what little I do seem to have.
Maybe the most vivid thing that I can imagine is the world map, but... I wouldn't call it visual. But I can recall that Europe is east of US, and Italy looks like a boot.
Perhaps it is just spatial facts.

A couple weeks ago, Neil deGrasse Tyson had neuroscientist David Eagleman as his guest on Star Talk. David discussed his friend and co-founder of Pixar, Ed Catmull, has aphantasia and that Catmull tested the directors and animators at Pixar, discovering that many of its top artists are also aphantasic!

They have a theory that artists who have to struggle more during the training and developing of being able to express on medium develop into better artists.
