POPSRepetition Makes False Beliefs Permanent Politicians and other unscrupulous types have long exploited what psychological studies are now confirming: due to the neurophysiology of the learning process, simple repetitive association between two concepts is enough to make false propositions "feel" true and well-supported. Worse, after enough exposure to such associations, subsequent denials can strengthen the perception of the falsehood instead of weakening it. (This is a major reason why the stigma of a false accusation can persist even after innocence is proven.) Indeed, repetition seems to be a key culprit. Things that are repeated often become more accessible in memory, and one of the brain's subconscious rules of thumb is that easily recalled things are true.

POPSMirrors Don’t Lie.. : -) “When people are made to be self-aware, they are likelier to stop and think about what they are doing,” Dr. Bodenhausen said. “A byproduct of that awareness may be a shift away from acting on autopilot toward more desirable ways of behaving.” Physical self-reflection, in other words, encourages philosophical self-reflection, a crash course in the Socratic notion that you cannot know or appreciate others until you know yourself.

POPSThe Future of Gaming I have tried to capture some hints about the future of gaming. As the author remarks: "For now, the only way to predict the future of gaming is to predict that all predictions will be wrong." Yet, it seems that in the not so far future, games are going to deeply affect the way we perceive our world. Especially the younger generations will be affected, and to some extent it is already happening. It seems that eventually games will not only affect our perception of the world, they WILL become a substantial part of our world.

POPSSCIENTISTS SHOW HALLUCINOGEN CREATES UNIVERSAL “MYSTICAL” EXPERIENCE in the 1950s, showed signs of therapeutic potential or value in research into the nature of consciousness and sensory perception. “Human consciousness…is a function of the ebb and flow of neural impulses in various regions of the brain-the very substrate that drugs such as psilocybin act upon,” Schuster says. “Understanding what mediates these effects is clearly within the realm of neuroscience and deserves investigation.” “A vast gap exists between what we know of these drugs-mostly from descriptive anthropology-and what we believe we can understand using modern clinical pharmacology techniques,” says study leader Roland Griffiths, Ph.D., a professor with Hopkins’ departments of Neuroscience and Psychiatry and Behavioral Biology. “That gap is large because, as a reaction to the excesses of the 1960s, human research with hallucinogens has been basically frozen in time these last forty years.”

POPSCan human consciousness survive without a brain? "Why do you think there is such resistance to studies like yours? Because we're pushing through the boundaries of science, working against assumptions and perceptions that have been fixed. A lot of people hold this idea that, well, when you die, you die; that's it. Death is a moment — you know you're either dead or alive. All these things are not scientifically valid, but they're social perceptions.How is technology challenging the perception that death is a moment?"

POPSThe Duplicates Paradox Personal identity is perceived as continuous through time. Yet this perception cannot be instantaneous, and must be based on memory. Given the fact that memories can be forgotten, altered or even fabricated, the question arises as to whether memories are essential for personal identity. Certainly no specific memory seems necessary for identity, but a perception of a continuity of the memory process is often believed to be. Subjective experience involves not just memory, but thoughts, desires, feelings and personality. Even when subjectivity is focused on the "outside world", this focus necessarily has a point of view. Any attempt to describe personal identity impersonally will lose an essential element. A self has both sensation and will.

POPSThe Sarcasm Mark Mulleflupp's Punctuation clip] This is an interesting idea, and this new punctuation mark could definitely have some usefulness, but the great fun of written sarcasm, for me, is in the detection. The element of uncertainty stimulates the brain, and a fine-tuning of one's perception.

POPSStudy: 93% Of People Talked About Once They Leave Room "As well as their breath, body odor, speech patterns, and the way they walked, not to mention general discussion based on the perception that the participant who had left the room was most likely a world-class prick." According to the data, 89 percent of volunteers appeared to listen attentively to the subject's receding footsteps, 47 percent raised their eyebrows and smirked as the subject left, and 23 percent mouthed the words "what the fuck" to others in the room as the door was closing, which usually triggered bouts of stifled giggling Perhaps most exciting was the 9 percent of volunteers who silently flipped the subject off as they left the room, Phillips said the lower-order cognitive functions responsible for knee-jerk gossiping may have played an ancient role in survival by encouraging those in proximity to band together.

POPSMaps of the Imaginary The worlds of many literary works have been subject to similar changes in perception. There is a whole genre of literary maps dedicated to tracing the real-world settings of fictional events, or the location of events once thought to have been real but now recognized as fiction. Do these maps count?

POPS3-D Viewing without Goofy Glasses As with earlier techniques, the illusion requires specially-created content to start with. In this case, a digital movie file effectively has two frames for each ordinary movie frame. The first is an ordinary color image, identical to what would be seen on a two-dimensional screen. A second frame, rather than showing a second offset view, encodes information about how viewers should perceive depth in the first frame. It appears as a grayscale version of the first, with white indicating foreground objects, black denoting deep background, and shades of gray indicating points in between.

POPSThe cognitive neuroscience of magic Magic combines multiple principles of attention, awareness, trust and perception to both overtly and covertly misdirect the audience. Whether they are used for performance art or as a means to illicitly separate victims from their money and valuables, the accomplished performer uses robust and intuitive manipulative devices that are of great interest to neuroscientists pursuing the neural underpinnings of cognition, memory, sensation, social attachment, causal inference and awareness.

POPSLifelike Animation Breakthrough AMD last week released a new chip with a billion transistors that will be able to show off creations such as Emily by allowing a much greater number of computations per second. "If you're trying to process the graphics in a photo-realistic animation, in real-time, there's a lot of computation involved," said Mr Koduri. He said that AMD's new chip - the Radeon HD 4870 X2 - was able to process 2.4 teraflops of information per second, meaning it had a capability similar to a computer that - only 12 years ago - would have filled a room. AMD's chip fits inside a standard PC. But he said that the line between what was real and what was rendered would not be blurred completely until 2020.

POPSHow Your Brain Controls Time
Warren Meck of Duke University argues that the brain measures long stretches of time by producing pulses. But the brain does not then count the pulses in the way a clock does. Instead, Meck suspects, it does something more elegant. It listens to the pulses as if they were music. At Humboldt University of Berlin in Germany, scientists have been building a model of how memory may store time. When neurons produce a regular cycle of signals, some signals come a little sooner and some come a little later. The researchers propose that as neurons pass these signals along, they can add tiny advances, some bigger than others. With these tiny wobbles, the brain can compress memories of time from several seconds down to hundredths of a second—a small enough package to store for later retrieval. As it stores time in memories, the brain may alter it in another way that is even more radical. It may record time so that our brains recall events in backward order. Scientists at MIT discovered re

POPSBeauty and the Brain Future work may elucidate the long-term effects of one's surroundings on brain function and the relationship between aesthetically pleasing spaces and their functionality. What one considers beautiful is, of course, influenced by culture, learning, and experience, and not everything we find beautiful will ultimately be traceable to the structure and function of our brain. The larger question "What is beauty?" still poses a major challenge, but answering it no longer seems so impossible.

POPSTaking A Shower Improves Moral Judgment The research was conducted through two experiments with university students. In the first, they were asked to complete a scrambled sentence task involving 40 sets of four words each. By underlining any three words, a sentence could be formed. For the neutral condition, the task contained 40 sets of neutral words, but for the cleanliness condition, half of the sets contained words such as ‘pure, washed, clean, immaculate, and pristine’. The participants were then asked to rate a series of moral dilemmas including keeping money found inside a wallet, putting false information on a resume and killing a terminally ill plane crash survivor in order to avoid starvation. The second experiment saw the students watch a ‘disgusting’ film clip before rating the same moral dilemmas. However, half the group were asked to first wash their hands.

POPSAnaïs Nin From being a cult figure of the early feminist movement, Anais later rose to international prominence with her writing. She is best known for her diaries but also produced a number of novels and a prose poem in surrealistic style as well as wonderful erotic short stories, published posthumously. Characterized by the use of powerful and, at times, disquieting imagery, her work reveals great sensitivity and perception. In 1973 she received an honorary doctorate from Philadelphia College of Art. She was elected to the National Institute of Arts and Letters in 1974.<<
