There's actually already a study on spatial reasoning and aphantasia: https://scholarscompass.vcu.edu/cgi/viewcontent.cgi?article=...

Basically, aphantasiacs tend to do just as well at spatial reasoning tasks as people with imagery, but tend to be somewhat slower and do not exhibit the gender gap that has been identified in the broader population.

I'm aphantasiac as well, and can identify with some of the experiences you've mentioned in this thread, and not at all with others. My spatial reasoning is great, and I'm a singer who has no problem at all with singing along to songs - if they're sufficiently regularly structured, even singing along with the chorus the second time it happens in a song I've never heard before. However, like you, I cannot replay sounds in my head. Memories are easily put behind me.

We're clearly very early in understanding what impact aphantasia has on people. It's a fascinating topic, and always interesting to teach people about.
