Working in the visual arts I think it made all of us feel particularly ashamed, didn't it ;) How could we miss it! But then it just shows how our brains are built and how we focus on one thing at a time. You're right - we base our memories on perceptions, and yet we still fight so fiercely about the truth of it all.<br /><br />Ah Keith, what a pleasure. Yes.. the fact the memory plays any role in the justice system is pretty scary really. <br /><br />I think your theory that emotion exists in order to remember things is a powerful one. Perhaps we are just in the process of evolving, and haven't reached an optimal stage for this function. The dials are not tweaked correctly? ;) It would be interesting to see into the far distant future and see how humans act in many millions of years. <br /><br />Memory and certainty can get mixed up with moral beliefs too... like you said, the more emotionally invested you are in something, the stronger the memory, and people can talk themselves into all sorts of things (religious delusions come to mind).<br /><br />As far as sleep goes, I think I've written about that before. With fibro I sleep very badly, sometimes just a couple of hours of light sleep a night, which is mostly why I have a very bad memory (fibro has other cognitive issues as well). My long term memory is much better than my recent one as I used to sleep a bit better when I was younger. Interestingly I remember emotions rather than specific details, so I can tell you how a book made me *feel* but not what it was about! Fascinating, I'd love to know more about how these two kind of memories are being encoded and why one is more successful than the other. Are the details more neocortex (new brain) and emotions more ancient brain? I must read more about it.<br /><br />Sigh... yes, Blade Runner has always been an asker of wonderful questions. How are any of us more 'human' than a replicant? What does 'human' mean? Wonderful movie. <br /><br />I just listened to an interesting episode of the Radiolab http://www.wnyc.org/shows/radiolab/episodes/2007/06/08 about memory and forgetting. One section that is particularly poignant looks at the idea of erasing memories. Just like Eternal Sunshine of the Spotless Mind ... another movie that delved into areas so compelling. Here is an article about the research - http://tinyurl.com/ycwblhz <br /><br />Yes M, I know what you mean. But it is a big lesson to see how my father has spent 80 years ruled by memories, tortured by them and not dealing with them at all. Many of them may not be what he believes they are (after all, other family members have different stories to tell), but rather a construct that allowed him to stay in that angry state - or perpetuated it. It's certainly something to try and be aware of. <br /><br />Perhaps it doesn't matter if our positive memories are not exactly true, just that we have them. They are still our own thoughts, and make us care about loved ones or places or things, whether or not there is 'absolute truth' in them.judehttps://www.blogger.com/profile/12927442663756605223noreply@blogger.comtag:blogger.com,1999:blog-1800850550357283758.post-46437134901322081632010-01-14T10:33:06.979+07:002010-01-14T10:33:06.979+07:00All fascinating.

Indeed, it&...Oh man there's so much to say....<br /><br />Indeed, it's well established that human memory is not very accurate. If you think about it, having memory is of course evolutionarily advantageous, but one doesn't need an extremely <i>accurate</i> memory to survive.<br /><br />But what's really nightmarish about memory is how one's confidence in a memory is faulty. Our levels of certainty are somehow separate from actual facts. So we might feel strongly that we remember something accurately when we don't. This is particularly bad in the justice system where witness testimony can sway a jury more than anything else. ("That was the man who robbed me! I'm sure of it!")<br /><br />In fact, I've heard that the situations which give rise to the highest levels of certainty are exactly the ones in which people's memories are the least accurate: Highly emotionally charged ones. (More about certainty and its evils after you post on it. There's an episode of "The Ascent of Man" about that which you must see.) <br /><br />So what is it about memory and emotion? Well, if you think about it, it makes sense that strongly emotional things should be remembered. If you got scared out of your wits there probably was a reason for it and therefore something to avoid in the future. Likewise, if something good happened, you'd want to remember that too.<br /><br />Arguably, we have emotion in order to remember things. In fact, you can think of emotion as the <i>mechanism</i> for encoding memory. Ever hear that you encode memories while you sleep? Are your dreams highly emotional? Scary perhaps? Could that be a side-effect of encoding the memory? Or the mechanism itself?<br /><br />And lastly, regarding Bladerunner, is her life any less valid because her memories came from someone else? What does "someone else" really mean in this case? As time passes and your memories change, are they wrong, or is the past just malleable? I'm not the same person I was 20 years ago, should my memories be?<br /><br />K.Keithnoreply@blogger.comtag:blogger.com,1999:blog-1800850550357283758.post-55071719552155478392010-01-12T08:46:05.232+07:002010-01-12T08:46:05.232+07:00There's also that experiment with the guy in t...There's also that experiment with the guy in the monkey suit that no one saw...<br /><br />http://www.telegraph.co.uk/science/science-news/3322642/Did-you-see-the-gorilla.html<br /><br />Which just goes to show that not only are memories in error, but so are our perceptions of the world, on which we base those memories!<br /><br />That's one reason I started blogging, and keeping an online diary of my vacations. Truth be told, I'll read some of those early trip reports and be like "aha! I'd forgotten that!"<br /><br />Our minds work in strange ways, that's for sure.spajadigithttps://www.blogger.com/profile/04796546096636247752noreply@blogger.com
