False memories can form within seconds, study finds

It can still mitigate some of it, of course, but I still find it a bit unnerving that even my short term memory is prone to making stuff up. Before, I had always imagined that this phenomenon was strictly related to the retrieval process of long term memories, and could therefore be avoided by writing things down the day they happened.
* No doubt you are still making a great improvement compared to simply relying on your memory.
* Although the experimental result is framed in terms of "false memories", I interpret it as "seeing what your brain expected to see". This is nothing new!
* It is worth recording your perceptions even if they're clouded by your expectations and preconceptions. You're recording your conscious experience. This is a valuable thing.
* The act of sitting down and writing out thoughts, feelings or memories is a mindful, peaceful and fulfilling experience that cannot easily be replaced. Simply putting words on a page (digitally or physically) often causes me to instinctively take a broader perspective.
I resolved to try and not live in my own world so much... After I shredded my old diary entries.
I would be extremely cautious drawing that conclusion just on the basis of this study. They were experimenting with recalling letters. Further research needs to be done to see what kinds of memories are affected by this and how. I still think writing a diary is important and valuable, it's just maybe not an infallible perfect record. It's certainly 100000% better than whatever phantom you now retain as a memory of an event 20 years later.
For me, it implies that we need to be aware of our biases and how they can affect how we interpret and remember an event. So instead of not writing a diary at all, I'd suggest continuing to write a diary and when writing also reflecting on your possible preconceptions/biases.
> Of course, this is only one study, involving a piece of knowledge that’s strongly reinforced throughout our lives (letters). So Otten and her team hope to keep testing the fallibility of short-term memory in other ways.
> Do the expectations that we have about people based on, for example, their gender, almost immediately start shaping what we remember about, say, their voice or facial expression? Or do I after only a few seconds start slightly misremembering certain data-representations, because it does not fit my beliefs about, say, climate change?” she said. “This is obviously a bit more complicated to explore than just asking people to look at a display of 6 letterlike items, but I look forward to exploring this further.”
I don't understand why people take one study and then use that as absolute truth about a general thing even though that single study only studied a tiny part of it.
The event is non-meaningful so the brain doesn’t record/file every detail about the experience; this of course would be different per individual.
Shocking the individual or tying an emotional response to the event may make it meaningful but probably won’t translate to the brain on its importance.
We are creatures of habit and instinct and if a human was to be trained on the importance of letter/pattern order recognition from an early age, they would most be more effective than a person who has ruled out the importance of such an experience or event.
- Store it.
- Sitting in storage
- Recall it.
With each subject to imperfections. For example, recall doesn't find something in storage so it "fills in the blanks".
The mind is not a machine. It's got plenty of quirks.
and considering that it's got pretty great manufacturing precision, tolerances, and MTBF :)
From the paper:
“To rule out that these errors reflect a perceptual error that has directly been encoded into STM, we test whether illusory responses increase over time: If the illusions are simply the result of misperceptions, their frequency of occurrence should remain the same over the time-course of STM—since in all cases initial perceptual inference has been completed. Therefore, if the number of reported illusions increases as the retention interval increases, this is best explained by memory-related processes taking place during the retention interval, so during STM storage itself, and not in the perceptual or encoding process.”
So, it seems their memories are right more often just after seeing the stimulus than a short time later (100ms or 1s, if I scanned the paper correctly).
My guess would be that the unconscious brain discards uninteresting data very quickly even if the conscious brain attends to that data.
These "memories" aren't recalled from my life, often it would be impossible for them to be, and yet they feel like mine.
I imagine there's some medical explanation for this, but I've no desire to approach a doctor with such symptoms!
Though, it looks little far fetched making big conclusions on the basis of experiments that is basically about remembering letters.
