What is your memory like? Do you have SDAM?

Michele DohertyMichele Doherty asked 2 months ago

I’ve just learned that there is a name for my inability to form a visual picture in my head, and am learning about the full impact of what that means regarding all of my senses. I haven’t read any mention of aphantasia affecting one’s ability to remember how to do things if you haven’t done them in a while. For example, in my job, there are tasks that I don’t do every day but maybe biweekly, and if I don’t look at my notes for a reminder I don’t remember the details, just the general idea. I definitely don’t remember past events in any kind of detail, and lots of times not even the event itself. Does this sound familiar? Do you experience challenges remembering past events and factual information about yourself?

There is speculation about whether bad memory and aphantasia are connected. I know some aphants have SDAM, which is Severely Deficient Autobiographical Memory. It means that you cannot relive vivid memories from a first person perspective. There are visualizing people that have SDAM, so it isn’t just an aphantasia thing, but I think having aphantasia can make SDAM worse in some ways because you already can’t visualize.

You may have SDAM without knowing it. I’d look into it, because I think I have it too. I get the feeling of just not remembering how to do stuff that you don’t do very often.

My memory seems about average. I learn and remember best by doing the thing. If I’ve done something a few times then it’s easy to remember, feels like it gets put in a permanent storage place in my brain. I can remember visual details of things if I put purposeful effort into it. The details are kept in a list of attributes like "Red shirt, short sleeves, fits loose" and such.

I do have trouble recognizing people, it’s not face blindness… it’s just hard to remember someone unelss we had a particularly interesting conversation or dance (I go tango dancing a lot) or they happen to have a really really unique appearence that’s easy to log in words in my head.

Remembering first person events in my life tends to take the shape of words spoken + words describing the event, what I was feeling emotionally (if anything), and sometimes physical memory (I have a physical sense in my memory/imagination instead of visual, so not full aphantasia)

This is a very interesting question. Rachel C is correct. There are some very early findings/evidence that suggests aphantasia might be linked to another phenomenon known as Severely Deficient Autobiographical Memory or SDAM for short.
Autobiographical memory is defined as both the recollection of personal past events (i.e. special events from your past) and factual knowledge about oneself (i.e. your favourite food as a kid).
People with SDAM can remember details about an event from their past because they’ve either seen a photo or deliberately learnt a story about what happened but they cannot "picture" being there.
This means that while they cannot experience the nostalgia of reliving the best times in life, the upside is that they can’t recall the pain associated with the bad things either making them far less likely to hold grudges as they can’t conjure up the emotion that made them feel bad in the first place. Pretty neat! Wish I was this way…
Some aphants have reported having both conditions present. You can read more about Susie McKinnon’s experience here.
Does this experience sound familiar? Do you think you might also have SDAM? Why do you think that is?

The issue of nostalgia is an interesting point. Could it be that a complete lack of nostalgia is a symptom  SDAM ? I left my native country at 26, and have been living in another place for 48 years; but never experienced nostalgia. Also, at the age of 10, I almost drowned in an industrial pool; I always remember this situation, and even see something; but never experienced a sense of horror.

I have an exceptionally good memory, especially for text and conversation. I can remember vivid emotional and verbal details of past events, especailly if I’m in the same location again.

I don’t have a strong experience of nostalgia – but then I don’t have a lot of good past to miss!
