Scientists Find Believing Can Be Seeing 169

Posted by samzenpus from the the-mind-is-quicker-than-the-eye dept.
Ponca City, We Love You writes "Scientists at University College London have found the link between what we expect to see, and what our brain tells us we actually saw revealing that the context surrounding what we see is all important — sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren't really there. A vague background context is more influential and helps us to fill in more blanks than a bright, well-defined context. This may explain why we are prone to 'see' imaginary shapes in the shadows when the light is poor. "Illusionists have been alive to this phenomenon for years," said Professor Zhaoping. "When you see them throw a ball into the air, followed by a second ball, and then a third ball which 'magically' disappears, you wonder how they did it. In truth, there's often no third ball — it's just our brain being deceived by the context, telling us that we really did see three balls launched into the air, one after the other." The original research paper is available on PLOS, the open-access, peer-reviewed journal."

      It may not be a breaking news story, but it's definitely interesting. I think we all have had things like this happen, and I guess I'm not surprised that it's triggered more by vague context. I've always just figured people were exaggerating when they describe stories about things that happened and someone else calls them out on it - but they probably thought they really saw what they claimed to see.

        Indeed. I took an Advanced Drivers training course from a police officer about a month ago, it really 'opened my eyes' so to speak. I'd been pretty appalled at my driving before, I didn't see any reason to keep to speed limits, but once you start trying to take in all the information you can from roadsigns and such, and you go on a skid course that demonstrates the braking distance difference between 20 and 30mph, you start to see the justification in having 20 limits outside schools and stuff like that. Save driving isn't about driving slowly of course - you can be perfectly safe at 110 (our instructor demonstrated this on a long straight, was funny to be doing that kind of speed legally :D ), but as you say training is very useful to get your brain noticing the right kind of things and not just going along on autopilot. After a while your driving will of course automatically incorporate the things that you have trained yourself to look out for, but it's still best to keep an active interest in what's happening all around your vehicle. I feel a bit of a hypocrite talking about road safety after the reputation I got for speeding around all the time, but hey I've not got any points on my license and I've not had an accident for a few years, because I was still sticking within what I considered to be my personal safety limits..

            Well, considering I've only been driving for a 'few years' and the accidents I had were within 6 months of my test :P Not exactly boasting, just saying that I don't consider my driving pre that course to have been reckless, especially compared to the average driver. The difference now is that I *know* that I'm a lot better than the average driver, and have been told so by someone that's been a police driving instructor for about 30 years. A lot of the things we were taught were things that I've been doing naturally (possibly partially because I was first taught to drive by my dad, who used to be in the police himself before becoming a coder), and I've unlearned some bad habits that I picked up over the years. I'm also obeying speed limits more now (not the ones on country roads, but in built up areas I am), but I don't going slower to be the primary reason for improved safety (or, rather, reduction of elements that could present a danger, since 'safety' can only really be seen in retrospect through a lack of accidents really), I see more my going slower as a result of firstly having more respect for the law through having been driving with a police officer and hearing that they understand that speed is not a primary factor in defining how safe a driver you are, and two it is a side effect of paying more attention - when I first was trying to take in everything like road signs that I'd never seen before, I automatically was driving at about 20mph just trying to get used to looking at them again, as well as reading them out. Now I can do my sign observations at any speeds, but since I got used to travelling at 30 without being too bored, I've been able to keep my speed down, and long may it continue (just because I feel guilty breaking the speed limits even when I know it's "safe" to do so!)

        Take a normal English Class. The bulk of the class is trying to teach people to get meaning out of litature and learning to read between the lines to get the underlining meaning. So you learn that you get an A+ when you read when Tess got off the tractor and her hands felt numb, then translate it to the numbing dehuminizing effect of the approaching indrustral revolution. Vs. a C+ when you read the the same part and you stated it was a means to express the feeling that you get after you ride a tractor for a long time, the author probably wrote it because most people who is his book proably isn't a farmer, so they would be learning how it feels to drive a tractor.
        We are trained to look so deeply and make meaning out of everything that it has driven our society batty. 20 Years ago a local grocery store called Price Chopper use to have a picture of a coin with a woman face on it with an Axe cutting the coin, the had to change the image of the coin because people beleaved that it was portraiting woman abuse.

Now, he has an instinct -- or maybe it's hardwired at an even lower level than that -- to make up patterns around those scattered facts, to fill in the blanks. So he imagines a category of people who 'see things where nothing exists'. Before long, he's convinced enough of this specific phenomenon -- of this entity which is purely a product of his own tendency to create patterns to explain the phenomena he senses -- that he actually starts posting about this group of people on slashdot, as if there actually were one specific kind of person who has this trait!

      And then other factors, psychological, move him to assume that he's 'better' than this entity that has popped up in his mind and that he now believes is an actual thing. He even begins to give patronising advice. To him, it's just as if he's *interacting* with this thing, this 'people who see things where nothing exists'. His self-deception is complete!

    All our experiences come from our senses, our eyes/ears/nose/skin/tongue send electrical impulses to our brain, the mind interpreters these groups of sensory experiences and we call it reality.

    Idealism says (as best i can describe) that "reality" is the mind's interpretation of these sensory experiences, what causes our senses to send a particular sensory experience to the brain isnt directly knowable, therefore not as relevant as the experience itself.

    It is the sensory experience itself that defines reality, i.e. reality is the effect not the cause.

    Scientists at University College London have found the link between what we expect to see, and what our brain tells us we actually saw revealing that the context surrounding what we see is all important -- sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren't really there. A vague background context is more influential and helps us to fill in more blanks than a bright, well-defined context.

    I think this phenomenon is often referred to as religion.

  • Something like this happened to me. Reading an article about how Trader Vic was about to donate a sculpture of Smiledon to UC Berkeley, before I got to the part where it was to be displayed, my brain decided it was going to be placed outside of the Life Sciences building, so my conscious mind read 'life sciences building'. However, when I turned to my roommate to tell him about this, my mouth said it was going to the 'Earth Sciences' building! This caught me by surprise, so I went back to the article and

  • Once a dog gets friendly playing a game of fetch with you, sometimes they don't let go of the ball to try and mess with you. That is when you start playing mind games with the dog. Often dogs will start running as soon as they see your arm swing. So just hold onto the ball, and they'll go running then get confused that they can't find the ball. Show them the ball, and they'll figure it out. Do it enough times so they don't go running when you swing you arm. Next, throw the ball regularly. If the dog b

Then all the sudden it "came into focus", so to speak, as a shoe and it was obviously a shoe, plain as day. I came to the conclusion that if something is viewed "out of context" (even though my shoe really wasn't) it can have a great impact on how you see or recognize it.

      A quick interpretation might be that people listening are simply 'making up' any difference they hear between the 'circuits'.

      However, I wonder if everyone is having a synaesthetic experience of the circuits -- that when you see the red light, you experience the sound as 'warmer', and when you see the blue light, you experience the the sound as colder and more distant. What do you think?
  • When we see things they are not labeled for us, nor is anything described. Our eyes stream video to our brain, and our ears stream audio, and so on. It is at our core that we process the messages that come in, use associations and memory to decypher what we see. Everything is open to interpretation based on what we know already.

  • This isn't terribly surprising. In the military you learn the principles of why things are seen. [army.mod.uk] The entire concept is about understanding that perception is very much about expectation. For instance, one thing you're taught is that position has a lot to do with it. If you see a large object on a road, your brain will tend to see it as a vehicle, even if it's not. Similarly, you can open the door of your fridge and not "see" the ketchup on the shelf because you were expecting to find it in the door.
