Here is a new, shorter version of our mental imagery survey. Please if you can spare a few minutes we would appreciate if you could take this & pass it along to others who might be interested. Thanks! tstbl.co/763-452

People with #aphantasia can’t mentally #visualize things. #Mentalimagery is a spectrum, and some lie outside it
A quick at-home test for aphantasia is called the red star or red apple test. Close your eyes and picture a red apple. How well can you see the apple visually on a scale of 1 to 5, with 1 being the most vivid? Can you see its color, shape and the length of the stem? Is it a bit hazy, coming in and out of focus?

(YouTube) Why don't we hallucinate our mental images? https://www.youtube.com/watch?v=pxY3RSexbzg Alexander Sulfaro on #aphantasia and #hyperphantasia, #MentalImagery. Have you ever wondered why mental images aren't as vivid as real images? And what's the difference between imagining something and hallucinating it?

CW: Vividness of mental imagery, aphantasia
This paper from 2020 by Rebecca Keogh, Johanna Bergmann and Joel Pearson shows that electrical manipulation of the excitability of neurons in the prefrontal and visual cortices can be used to temporarily increase or decrease vividness of mental imagery (at least for people with some visual imagery): https://doi.org/10.7554/eLife.50232
Mike Perrotta provides some background, and makes the research a little more accessible for the layperson in this 2021 article for the Aphantasia Network: https://aphantasia.com/article/science/shocking-insights/

Maybe its the visuals that's my connection. In science I always created my figures first, and then wrote to them. In public speaking, I snapped a mental picture of a lean outline. That way, if\when I forgot my place I could loop back to my central points and conclusion. A linear presentation is easily broken with a small distraction.
