Regarding aphantasia, I've had a lot of anecdotal success with this image [1]. I'm personally about a 2, and I've found that this test tends to be quiet understandable and revealing to a variety of audiences. Anecdotally, I gave this chart to my friends in my school's band (N=6), and none of them had aphantasia (excluding me), and two of them reported hyperphantasia, and intensely vivid audiovisual imagination. I also gave this chart to my friends in software engineering and cybersecurity (N=4), and two of them also had aphantasia. I'm hesitant to draw conclusions, given a small sample size, but I'd hypothesize that there is a larger proportion of aphantasic individuals in STEM than in the arts.
