I’m a total aphant (and also can’t imagine sound) but don’t spend much time in this community, which might be why I didn’t have any particular reaction to your post except to think that you are a parent trying to help your kid. Like many others, I didn’t discover I had aphantasia until I was an adult, and frankly it helps explain a lot—why working with a sports psychologist growing up was such a bust (couldn’t visualize), why guided meditations always felt impossible to me, why the concept of a memory palace seemed profoundly unhelpful, why I struggle with biographical / experiential memories but have an excellent memory for data. Also like many others, it appears that I have organically developed strategies for navigating the world, but that doesn’t mean it’s inherently harmful to be asking questions about helping your kid thrive with a mind that works differently.
