This one just occurred to me, but I have always had iffy handwriting and recently have been trying to learn Russian which is reliant on fairly tricky cursive.
I have found the whole experience of learning a new style of cursive to be frustratingly difficult and was wondering if not having a good visual memory might lend itself to a slightly harder time of it.
Nothing special except that everything I write is very tiny, apparently. That might be related to confidence, according to some, but I don’t think it’s necessarily true.
On the other hand, my handwriting becomes much more ‘precise’ and pretty while on ADHD meds, but that’s not related to aphantasia.
