How your memories can be twisted under social pressure | KurzweilAI - 0 views

  •  
    Listen up, Facebook and Twitter groupies: how easily can social pressure affect your memory? Very easily, researchers at the Weizmann Institute and University College London have proved, and they think they even know what part of the brain is responsible. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. Volunteers watched a documentary film in small groups. Three days later, they returned to the lab individually to take a memory test, answering questions about the film. They were also asked how confident they were in their answers. They were later invited back to the lab to retake the test. This time, the subjects were also given supposed answers of the others in their film-viewing group (along with social-media-style photos) while being scanned in a functional MRI (fMRI) that revealed their brain activity. Is most of what you know false? Planted among these were false answers to questions the volunteers had previously answered correctly and confidently. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. To determine if their memory of the film had actually undergone a change, the researchers invited the subjects back to the lab later to take the memory test once again, telling them that the answers they had previously been fed were not those of their fellow film watchers, but random computer generations. Some of the responses reverted back to the original, correct ones, but get this: despite finding out the scientists messed with their minds, close to half of their responses remained erroneous, implying that the subjects were relying on false memories implanted in the earlier session. An analysis of the fMRI data showed a strong co-activation and connectivity between two brain areas: the hippocampus and the amygdala. Social reinforcement could act on the amygdala to persuade our brains to replace a strong memory wi

    Brain, bodily awareness, and the emergence of a conscious self: these entities and their relations are explored by Germanphilosopher and cognitive scientist Metzinger. Extensively working with neuroscientists he has come to the conclusion that, in fact, there is no such thing as a "self" -- that a "self" is simply the content of a model created by our brain - part of a virtual reality we create for ourselves. But if the self is not "real," he asks, why and how did it evolve? How does the brain construct the self? In a series of fascinating virtual reality experiments, Metzinger and his colleagues have attempted to create so-called "out-of-body experiences" in the lab, in order to explore these questions. As a philosopher, he offers a discussion of many of the latest results in robotics, neuroscience, dream and meditation research, and argues that the brain is much more powerful than we have ever imagined. He shows us, for example, that we now have the first machines that have developed an inner image of their own body -- and actually use this model to create intelligent behavior. In addition, studies exploring the connections between phantom limbs and the brain have shown us that even people born without arms or legs sometimes experience a sensation that they do in fact have limbs that are not there. Experiments like the "rubber-hand illusion" demonstrate how we can experience a fake hand as part of our self and even feel a sensation of touch on the phantom hand form the basis and testing ground for the idea that what we have called the "self" in the past is just the content of a transparent self-model in our brains. Now, as new ways of manipulating the conscious mind-brain appear on the scene, it will soon become possible to alter our subjective reality in an unprecedented manner. The cultural consequences of this, Metzinger claims, may be immense: we will need a new approach to ethics, and we will be forced to think about ourselves in a fundamentally new way. At

    "James W. Pennebaker's interest in word counting began more than 20 years ago, when he did several studies suggesting that people who talked about traumatic experiences tended to be physically healthier than those who kept such experiences secret. He wondered how much could be learned by looking at every single word people used - even the tiny ones, the I's and you's, a's and the's."

*A Brain Scientist's Take on Writing*: What Mirror Images and Foreign Scripts Tell Us A... - 0 views

  • For most adults in literate countries, reading is so well practiced that it’s reflexive. If the words are there, it's impossible not to read.
  • If you raise a child on a desert island, he'll learn to eat, walk, and sleep, but odds are he won't spontaneously pick up a stick and start writing. For most of human history, written language didn't even exist. Reading as a cultural invention has only been around for a few thousand years, a snap of a finger in evolutionary terms.
  • we’re very good at seeing, and the trick is just to retune that machinery to the demands of reading.
  • ...11 more annotations...
  • But even on a basic visual level, we have to somewhat reprogram our visual systems.
  • Mirror invariance, the idea that something flipped sideways is still the same object, is a core property of our visual systems, and for good reason.
  • What's the mirror image of b? Now it's a completely different letter: d.
  • Mirror reversal is overwhelmingly common in beginning writers, from the occasional flipped letter to whole words written as a mirror image. Kids do this spontaneously. They never actually see flipped letters in the world around them. It's as if their brains are too powerful for the task.
  • With practice however, we do retrain our brains to read
  • Does the brain of a reader look different from that of a nonreader?
  • Since blood flow is tied to brain activity, fMRI allows us to see the patches of brain involved in different tasks.

      Bit of an oversimplification, no?
  • They found that most participants did indeed have a brain region that responded more to words than objects.
  • This is rather remarkable, that the brain would develop a specialized area for an artificial category of images.
  • need more proof that this region developed as a result of learning to read.
  • If reading experience does alter the brain, you would expect English readers and English/Hebrew readers to have different brain responses to Hebrew. And this is indeed what Baker found. The bilingual readers had high activation for both Hebrew and English in their word region, while monolingual English readers only had high activation for English.

The Most Mysterious of Human Feats: Walking on The Red-Hot Coals - 0 views

  •  
    A burning question: Can science explain the mystery of the fire walk?...All over the world, from Japan to Sri Lanka, Spain to Bora Bora, fire walking has been a high point of intense religious ritual. The mystery has always been how the human bodies can with-stand the high temperature involved, how fire walkers emerge unscathed from the burning pit with no apparent sensation of pain.
