Y'all have memories? ​:neofox_googly_woozy:​

#SDAM

I can remember facts from my past, but I can't actually experience those memories again.

It's like having a bullet-point list of what happened, without the emotional and video replay.

This realisation feels important (to me), even if it took me a while to notice.

It continues my understanding of my neurodivergence that started with realising I had aphantasia, through a diagnosis for ADHD with a surprise autism side-dish to this point.

I did some reading about Aphantasia and associated neurodifferences. One of the documents had a clearer description of Severely Deficient Autobiographical Memory (SDAM) than I’d seen before.

I realise, several years after I first considered the possibility, that I probably have SDAM. I previously discounted the possibility because the name seemed dramatic. The phrase 'Severely Deficient' suggests a total lack of memory, and that's not what I have.

Well, fuck. I just came across a comment on Reddit that makes me think. I've already witnessed some of these things. I don't know that I can be a witness.

"Because I have aphantashia and SDAM, I know these things won't haunt me the same way. Because of this, I feel I have an obligation to witness such things because somebody has to".

@jmyarlett I don’t know if this will help at all, but I discovered a few years ago that I have #aphantasia – the “lack of a mind’s eye” 🫥

one of the things that often comes along with it (or is a comorbibity) is Severely Deficient Autobiographical Memory (#SDAM), which means that we don’t seem to lay down very strong “first-person” memories

I guess it’s technically a “deficiency” (depending on context, depending on who you’re talking to), but it also seems to bring strengths with it as well (e.g. traumatic memories may not hang around / be as overwhelming)

I don’t know if it’s the same for you (re: strengths) but I hope so 🤞

Your post made me realize a possible cause for my SDAM - aphantasia! Actually I've wondered what SDAM means, since my autobiographical memoiry is pretty much as vivid as my immediate experience - not very vivid! If your real time view of life is a vague snapshot and a few related words, of course your memory of that bit of life will be "deficient".

Does anyone have historical memories that are more detailed than the original experience? Unless they artificially embroider them after the experience is over?

Was talking memory with a friend recently and mentioned SDAM, Severely Deficient Autobiographical Memory, that they had never heard of. Another poll friends.

#TIL about severely deficient autobiographical memory - and maybe that's what it has been all along.

#Introduction with a billion #hashtags...

I'm Alba, a #trans #nonbinay #bisexual #autistic #vegan #antifascist #activist from #Nijmegen, #NL. In addition to my #autism, I've also got #ADHD, #hyperlexia, assorted auditory processing and executive function issues, #aphantasia and #SDAM (Severely Deficient Autobiographical Memory).

I'm a senior #IT #tech at a large #international company and an avid #volunteer as well: I do IT support/admin for a national #TransRights #advocacy #NGO (Transvisie), I'm a volunteer driver for an NGO that provides low cost door to door transportation for (mostly) the #elderly (#ANWB AutoMaatje), and once or twice per month I collect donated #bread from #artisanal bakeries for distribution to #unhoused people, #refugees, and people who are dealing with #poverty (Buiten de Brood).

I speak #Nederlands, #français, #English, #Deutsch and #Esperanto. I play #saxophone - I have a bari sax, a tenor sax and a soprano sax. I also have a #flute and a #ukelele but I don't play those nearly as well as the saxes. I love playing #TTRPG like #DnD5e and #PF2e, and I have two #cats, an orange slonk called Hobbes and a void chonk called Nita.

I used to hang out on mastodon.lol until early 2023 when that instance shut down. I then moved to todon.nl and eventually decided to hop on to blahaj.zone ​:Blobhaj_Love:​
