Some people can't see mental images

So, if you watch a poor person begging for food on the street, how do you process that in the future? Do you rely on the remembered feeling and literal observation in words? How do you not remember what you saw?

I "know" that I saw someone begging on the street. I might remember other "facts" as they seemed appropriate. But that's it. If you asked me what color their hair was or what they were wearing I would have no idea unless I had chosen to make a note of that fact.

I rely on the feeling, the sounds, the words on the sign, or by analogy to another thing. I don't remember what it looked like in the way that in a dream I believe I physically see things

How will you remember this comment in 2 hours? Will you visually see the words? You don't need to visually see something that happened to remember it happened or the idea of it. I don't need to visualize Harry Potter in my head to remember the fact he has a lightning bolt shaped scar on his forehead. I just remember the fact.

Adding a data point. I don’t think this is aphantasia, but rather SDAM (severely deficient autobiographical memory). For the future, the memory has to be recorded as facts as the original experience is gone. This means the emotions and other aspects cannot be experienced again. Recording things like, I saw this, I felt like this, I intend to do this.

Not all people who can’t visualise have this SDAM thing (though it is a common overlap), but SDAM means I would remember an event like this less than a problem at work (as an example), without intentional effort to transcribe it.

This sounds a bit cold, but it’s not as cold as it looks. If I read your description of the poor person begging for food, I am emotionally moved. In a similar way, if I examine my memory of the poor person begging for food, I am emotionally moved. I might not be reliving the experience, but the narrative I’ve preserved is enough.

This is why I like listening to my wife describe things we’ve done together. I often don’t remember it, but the narrative is still emotionally impacting. She’s my external memory for things that have happened in our lives.
