How the brain creates the 'buzz' that helps ideas spread - 1 views

  • UCLA psychologists have taken a significant step toward answering these questions, identifying for the first time the brain regions associated with the successful spread of ideas, often called "buzz."
  • "Our study suggests that people are regularly attuned to how the things they're seeing will be useful and interesting, not just to themselves but to other people,"
  • We always seem to be on the lookout for who else will find this helpful, amusing or interesting, and our brain data are showing evidence of that.
  • ...6 more annotations...
  • The study findings are published in the online edition of the journal Psychological Science, with print publication to follow later this summer.
  • "Now we have mapped the brain regions associated with ideas that are likely to be contagious and are associated with being a good 'idea salesperson.' In the future, we would like to be able to use these brain maps to forecast what ideas are likely to be successful and who is likely to be effective at spreading them."
  • the interns who were especially good at persuading the producers showed significantly more activation in a brain region known as the temporoparietal junction, or TPJ, at the time they were first exposed to the pilot ideas they would later recommend.
  • We found that increased activity in the TPJ was associated with an increased ability to convince others to get on board with their favorite ideas.
  • Thinking about what appeals to others may be even more important."
  • The TPJ, located on the outer surface of the brain, is part of what is known as the brain's "mentalizing network," which is involved in thinking about what other people think and feel.
  •  
    Interesting findings. The emphasis here is on identifying activity of the brain that indicates a person's effectiveness with passing on (sharing) information. While that is notable, it would be great to know what activity indicates that the information has merit in and of itself. We have plenty of buzz in our world. What we need are authoritative sources.

The Problem of Consciousness - 1 views

  • The Problem of Consciousness* John R. Searle (copyright John R. Searle) Abstract: This paper attempts to begin to answer four questions. 1. What is consciousness? 2. What is the relation of consciousness to the brain? 3. What are some of the features that an empirical theory of consciousness should try to explain? 4. What are some common mistakes to avoid? The most important scientific discovery of the present era will come when someone -- or some group -- discovers the answer to the following question: How exactly do neurobiological processes in the brain cause consciousness? This is the most important question facing us in the biological sciences, yet it is frequently evaded, and frequently misunderstood when not evaded. In order to clear the way for an understanding of this problem. I am going to begin to answer four questions: 1. What is consciousness? 2. What is the relation of consciousness to the brain? 3. What are some of the features that an empirical theory of consciousness should try to explain? 4. What are some common mistakes to avoid?
  • If science is supposed to give an account of how the world works and if subjective states of consciousness are part of the world, then we should seek an (epistemically) objective account of an (ontologically) subjective reality, the reality of subjective states of consciousness. What I am arguing here is that we can have an epistemically objective science of a domain that is ontologically subjective.

The Hidden Savant in You | Psychology Today - 0 views

  • Savants can perform extraordinary cognitive feats much like trained experts, but unlike experts they usually cannot describe what makes them so talented, seemingly relying on intuition rather than conscious deliberation to quickly make choices.
  • he consensus among many researchers is that intuitions are judgments made by unconscious processes in the brain.
  • Studies have shown that inhibiting activity in certain areas of the brain can facilitate solving geometric puzzles.
  • ...6 more annotations...
  • Allan Snyder has used transcranial direct current stimulation (DCS) to alter the activity both in the left and right hemispheres.
  • DCS was applied for only ten minutes, specifically to decrease activity in the left hemisphere and increase activity in the right hemisphere, 40 percent of subjects were able to solve the puzzle.
  • Tasks like solving the nine-dots puzzle are notoriously difficult because of our brains are structured in such a way as to limit creativity.
  • The left hemisphere is thought to govern the role that right-brain activity may play in cognition. Inhibiting activity in the left hemisphere of the brain is thought to remove the predisposition to interpret random elements in meaningful ways, allowing for more creative solutions generated in the right brain to make it into consciousness.
  • Savants thus may have a greater degree of conscious access to judgments of unconscious processes than non-savants.
  • As we become more skilled at manipulating brain processes through psychoactive drugs or electronic devices, we may be able to invoke savant-like skills in neurotypical people.

Integral Options Cafe: Antonio Damasio - Emotion, Feeling, and Social Behavior: The Bra... - 0 views

  • his contention that consciousness is not merely a by-product of brain activity, but is a necessary function of the body as a whole, including the brain.
  • he proposes at least four levels of self, from least complex to most complex:1. Neural Self (or proto-self) - a short term collection of neural patterns of activity which represent the current state of the organism2. Core Self - a second-order entity which maps the state of the proto-self in rather the same way the proto-self maps the current state of the body: whenever an encounter with an object impinges on the proto-self, the change is registered by activity in the core self3. Autobiographical Self - draws on permanent (though modifiable) memories instead of just the immediate experiences which power the core self. At this point, there is a real, though still pre-linguistic, sense of self. Damasio thinks chimpanzees and probably dogs enjoy this level of consciousness4. Reflective Self - greater use of longer-term memory, delivers the kind of foresighted, reflective consciousness which we typically associate with human beings
  • In Damasio's view, one which I share, emotions are body states that then are interpreted by the brain to assign a label based on memory and previous learning.

  • Those who were given no information or false information labeled their own experience in line with the behavior of the confederate, not having any other information on which to base their feelings.

New Device Allows Brain to Bypass Spinal Cord, Move Paralyzed Limbs - ScienceNewsline - 0 views

  • For the first time ever, a paralyzed man can move his fingers and hand with his own thoughts thanks to an innovative partnership between The Ohio State University Wexner Medical Center and Battelle.
  • “It’s much like a heart bypass, but instead of bypassing blood, we’re actually bypassing electrical signals,” said Chad Bouton, research leader at Battelle. “We’re taking those signals from the brain, going around the injury, and actually going directly to the muscles.”

  • During a three-hour surgery on April 22, Rezai implanted a chip smaller than a pea onto the motor cortex of Burkhart’s brain. The tiny chip interprets brain signals and sends them to a computer, which recodes and sends them to the high-definition electrode stimulation sleeve that stimulates the proper muscles to execute his desired movements. Within a tenth of a second, Burkhart’s thoughts are translated into action.
  • Battelle also developed a non-invasive neurostimulation technology in the form of a wearable sleeve that allows for precise activation of small muscle segments in the arm to enable individual finger movement, along with software that forms a ‘virtual spinal cord’ to allow for coordination of dynamic hand and wrist movements.
  • As part of the study, Burkhart worked for months using the electrode sleeve to stimulate his forearm to rebuild his atrophied muscles so they would be more responsive to the electric stimulation.

The dreams of readers | ROUGH TYPE - 1 views

  • Psychologists and neurobiologists have begun studying what goes on in our minds as we read literature, and what they’re discovering lends scientific weight to Emerson’s observation.
  • “aesthetic emotions” that we feel when we view art from a distance, as a spectator:
  • We create our own version of the piece of fiction, our own dream, our own enactment.” Making sense of what transpires in a book’s imagined reality appears to depend on “making a version of the action ourselves, inwardly.”
  • ...21 more annotations...
  • The scholars used brain scans to examine the cellular activity that occurs inside people’s heads as they read stories. They found that “readers mentally simulate each new situation encountered in a narrative.”
  • When, for example, a character in a story puts a pencil down on a desk, the neurons that control muscle movements fire in a reader’s brain. When a character goes through a door to enter a room, electrical charges begin to flow through the areas in a reader’s brain that are involved in spatial representation and navigation.
  • More than mere replication is going on.
  • we really do enter, so far as our brains are concerned, a new world — one conjured not just out of the author’s words but out of our own memories and desires — and it is our cognitive immersion in that world that gives reading its emotional force.
  • ” A work of literature, particularly narrative literature, takes hold of the brain in curious and powerful ways.
  • there are the “narrative emotions” we experience when, through the sympathetic actions of our nervous system, we become part of a story, when the distance between the attendee and the attended evaporates
  • A 2009 experiment conducted by Oatley and three colleagues suggests that the emotions stirred by literature can even alter, in subtle but real ways, people’s personalities.
  • Norman Holland, a scholar at the McKnight Brain Institute at the University of Florida, has been studying literature’s psychological effects for many years, and he offers a provocative answer to that question.
  • when we open a book, our expectations and attitudes change. Because we understand that “we cannot or will not change the work of art by our actions,” we are relieved of our desire to exert an influence over objects and people and hence can “disengage our [cognitive] systems for initiating actions.”
    • David McGavock
       
      Theory of mind 
  • The central subject of literature is society, and when we lose ourselves in a book we often receive an education in the subtleties and vagaries of human relations.
  • reading tends to make us at least a little more empathetic, a little more alert to the inner lives of others.
  • can strengthen a person’s “theory of mind,” which is what psychologists call the ability to understand what other people are thinking and feeling.
  • That frees us to become absorbed in the imaginary world of the literary work.
  • Jeff Jarvis, a media consultant who teaches journalism at the City University of New York, gave voice to this way of thinking in a post on his blog. Claiming that printed pages “create, at best, a one-way relationship with a reader,” he concluded that, in the internet era, “the book is an outdated means of communicating information.” He declared that “print is where words go to die.”
  • Society is growing ever more skeptical of the value of solitude. The status quo treats with suspicion  even the briefest of withdrawals into inactivity and apparent purposelessness. We see it in the redefinition of receptive states of mind as passive states of mind.
  • the arts of production and consumption, of getting stuff done, to which most of us devote most of our waking hours.
  • In a 2003 lecture, Andrew Louth, a theology professor at the University of Durham in England, drew a distinction between “the free arts” and “the servile arts.” The servile arts, he said, are those “to which a man is bound if he has in mind a limited task.”
  • free arts, among which Louth included reading as well as meditation, contemplation, and prayer, are those characterized, in one way or another, by “the search for knowledge for its own sake.”
  • We open ourselves to aesthetic and spiritual possibilities.
  • It may be that readers have to enter a state of languid pleasure, a dream, before they can experience the full spermatic vitality of a book. Far from being a sign of passivity, the reader’s outward repose signals the most profound kind of inner activity, the kind that goes unregistered by society’s sensors.

HOW CULTURE DROVE HUMAN EVOLUTION | Edge.org - 0 views

  • how culture drove human evolution
  • cultural brain hypothesis—this is the idea that the real driver in the expansion of human brains was this growing cumulative body of cultural information, so that what our brains increasingly got good at was the ability to acquire information, store, process and retransmit this non genetic body of information.

  • Chimps, other primates, have dominant status.
  • social status
  • second kind of status. We call this status prestige.
  • from being particularly knowledgeable or skilled in an area,
  • From this we've argued that humans have two separate kinds of status, dominance and prestige
  • give them deference in exchange for knowledge that you get back
  • you want to isolate the members of your group who are most likely to have a lot of this resources, meaning a lot of the knowledge or information that could be useful to you in the future
  • some of the big questions are, exactly when did this body of cumulative cultural evolution get started?
  • may have started early
  • another possibility is that it emerged about 800,000 years ago.
  • here's theoretical models that show that culture, our ability to learn from others, is an adaptation to fluctuating environments.
  • Another signature of cultural learning is regional differentiation and material culture, and you see that by about 400,000 years ago
  • 400,000 years ago
  • there's another possibility that it was a different kind of ape that we don't have in the modern world: a communal breeding ape that lives in family units rather than the kind of fission fusion you might see in chimpanzees
  • In the Pliocene, we see lots of different kinds of apes in terms of different species of Australopithecus.
  • we now have evidence to suggest that humans were communal breeders, so that we lived in family groups maybe somewhat similar to the way gorillas live in family groups, and that this is a much better environment for the evolution of capacities for culture than typical in the chimpanzee model
  • for cultural learning to really take off, you need more than one model.
  • trying out different technique
  • take advantage of the variation
  • the question is, how did we become such long distance runners?
  • only humans have it
  • humans who don't know how to track animals, can't run them down
  • idea being that the religions of modern societies are quite different than the religions we see in hunter gatherers and small scale societies
  • Most recently I've been also thinking about the evolution of societal complexity.
  • when societies begin to get big and complex
  • large-scale cooperation
  • What are the causal processes that bring these things about?
  • There's an interaction between genes and culture. First you have to get the culturally transmitted knowledge about animal behavior and tracking and spore knowledge and the ability to identify individuals, which is something you need to practice, and only after that can you begin to take advantage of long distance running techniques
  • I've worked in a couple of different areas on this, and one is religion.
  • there was an intense period that continues today of intergroup competition, which favors groups who have social norms and institutions that can more effectively expand the group while maintaining internal harmony
  • they've been shaped in ways that galvanize cooperation in larger groups
  • In small-scale hunter-gatherer religions, the gods are typically whimsical. They're amoral.
  • but as we begin to move to the religions in more complex societies, we find that the gods are increasingly moralizing.
  • if you remind believers of their god, believers cheat less, and they're more pro social or fair in exchange tasks,
  • more pro social in are the ones with anonymous others, or strangers. These are the kinds of things you need to make a market run to have a successful division of labor
  • ritual plays a role in this
  • rituals seem to be sets of practices engineered by cultural evolution to be effective at transmitting belief and transmitting faith
  • elevate the degree of belief in the high-moralizing gods
  • high-moralizing gods will often require rituals of this kind
  • Speaking in unison, large congregations saying the same thing, this all taps our capacity for conformist transmission;
  • People also engage in what we call credibility-enhancing displays [during rituals]. These are costly things. It might be an animal sacrifice or the giving of a large sum of money or some kind of painful initiation rite
  • We think religions are just one element, one way in which culture has figured out ways to expand the sphere of cooperation and allow markets to form and people to exchange and to maintain the substantial division of labor.
  • There's a lot of risk in developing specialization because you have to be confident that there's a market there that you can engage with. Whereas if you're a generalist and you do a little bit of farming, a little bit of manufacturing, then you're much less reliant on the market. Markets require a great deal of trust
  • In the intellectual tradition that I'm building on, culture is information stored in people's heads that gets there by some kind of social learning
  • We tend to think of cultural transmission, or at least many people think of cultural transmission as relying on language
  • , it's quite clear that there is a ton of cultural transmission that is just strictly by observational learning.
  • what we don't see amongst other animals is cumulative cultural evolution.
  • you can learn one thing from one generation, and that begins to accumulate in subsequent generations.
  • One possible exception to that is bird song.
  • One of the interesting lines of research that's come out of this recognition is the importance of population size and the interconnectedness for technology.
  • looking at a case study in Tasmania.
  • You start out with two genetically well-intermixed peoples. Tasmania's actually connected to mainland Australia so it's just a peninsula. Then about 10,000 years ago, the environment changes, it gets warmer and the Bass Strait floods, so this cuts off Tasmania from the rest of Australia, and it's at that point that they begin to have this technological downturn
  • You can show that this is the kind of thing you'd expect if societies are like brains in the sense that they store information as a group and that when someone learns, they're learning from the most successful member
  • study by Rob Boyd and Michelle Kline
  • larger islands had much bigger and more complex fishing technologies, and you can even show an effective contact. Some of the islands were in more or less contact with each other,
  • more in contact, you have fancier tools, and that seems to hold up.
  • rates of innovation should continue to increase, especially with the emergence of communication technologies
  • As an individual inventor or company, you're best off if everybody else shares their ideas but you don't share your ideas because then you get to keep your good ideas, and nobody else gets exposed to them, and you get to use their good ideas, so you get to do more recombination.
  • An important thing to remember is that there's always an incentive to hide your information.
  • Embedded in this whole information-sharing thing is a constant cooperative dilemma in which individuals have to be willing to share for the good of the group.
  • a norm of information sharing is a really good norm to have
  • I've done a lot of work on marriage systems with the evolution of monogamy.
  • Eighty-five percent of human societies have allowed men to have more than one wife
  • pushes us towards polygyny
  • But in the modern world, of course, monogamy is normative, and people who have too many wives are thought poorly of by the larger society. The question is, how did this ever get in place?
  • European Marriage Pattern,
  • Athens legislates the first rules about monogamous marriage
  • people are ready to moralize it,
  • it does seem to have societal level benefits. It reduces male-male competition. We think there's evidence to say it reduces crime, reduces substance abuse, and it also engages males in ways that cause them to discount the future less and engage in productive activities rather than taking a lot of risks
  • If I talk about normative monogamy as being successful, I mean that it spread,
  • especially if you have a society with widely varying amounts of wealth, especially among males. Then you're going to have a situation that would normally promote high levels of polygyny
  • to get into the mating and marriage market you would have to have a high level of wealth if we were to let nature take it's course
  • Part of my program of research is to convince people that they should stop distinguishing cultural and biological evolution as separate in that way. We want to think of it all as biological evolution. 
  • Culture is part of our biology.
  • We now have the neuroscience to say that culture's in our brain, so if you compare people from different societies, they have different brains.
  • Cognition and our ability to think are all interwoven,
  • A good example of this is the placebos. Placebos are something that depend on your cultural beliefs. If you believe that something will work, then when you take it, like you take an aspirin or you take a placebo for an aspirin, it initiates the same pathways as the chemically active substance. Placebos are chemically inert but biologically active, and it's completely dependent on your cultural beliefs.
  • One of the large research projects that I run in an effort to understand human sociality is called The Root of Human Sociality Project.
  • at the time to something called the Ultimatum Game, and the Ultimatum Game seemed to provide evidence that humans were innately inclined to punish unfairness.
  • behavioral economists find that students give about half, sometimes a little bit less than half, and people are inclined to reject offers below about 30 percent
  • The older you get, even if you have more wealth and more income, you're especially inclined to only offer half, and you'll reject offers below 40 percent.
  • I was thinking that the Machiguenga would be a good test of this
  • I did it in 1995 and 1996 there, and what I found amongst the Machiguenga was that they were completely unwilling to reject, and they thought it was silly. Why would anyone ever reject?
  • they made low offers, the modal offer was 15 percent instead of 50, and the mean comes out to be about 25 percent.
  • over the next two summers these field anthropologists went to the field and conducted the ultimatum game as well as a few other games
  • we found is that societies vary dramatically, from societies that would never reject, to societies that would even reject offers above 50 percent, and we found that mean offers ranged across societies from about 25 percent to even over 50 percent. We had some of what we called hyper fair societies. The highest was 57 percent in Lamalera, Indonesia.
  • able to explain a lot of the variation in these offers with two variables. One was the degree of market integration.
  • there seemed to be other institutions, institutions of cooperative hunting seemed to influence offers.
  • measured market integration much more carefully
  • subsequent project
  • large number of other variables, including wealth, income, education, community size, and also religion.
  • did the Ultimatum Game along with two other experiments. The two other experiments were the Dictator Game (the Dictator Game is like the Ultimatum Game except the second player doesn't have the option to reject) and the Third Party Punishment Game.
  • Third Party Punishment Game, there are three players and the first two players play a Dictator Game.
  • This gives us two different measures of willingness to punish strangers
  • one is rejection in the Ultimatum Game
  • three measures of fairness
  • size of the community predicts willingness to punish
  • suggesting that if you have small communities, you don't need punishment.
  • It could be some kind of reputational mechanism
  • There's a number of different ways to create norm systems that operate like that.
  • In a big society punishment can be most effective because reputational mechanisms can be weak. If you're in a big society and you encounter somebody, you probably don't have friends in common through which you could pass reputational information for which punishment could be generated. You might want to punish them right on the spot or someone who observes the interaction might want to punish them right on the spot or call the authorities or whatever, which is also costly.
  • This creates a puzzle because typically people think of small-scale kinds of societies, where you study hunter-gatherers and horticultural scattered across the globe (ranging from New Guinea to Siberia to Africa) as being very pro social and cooperative.
  • but the thing is those are based on local norms for cooperation with kin and local interactions in certain kinds of circumstances
  • these norms don't extend beyond food sharing. They certainly don't extend to ephemeral or strangers
  • large-scale society run you have to shift from investing in your local kin groups and your enduring relationships to being willing to pay to be fair to a stranger.
  • if you're going to be fair to a stranger, then you're taking money away from your family.
  • A commitment to something like anti-nepotism norms is something that runs against our evolutionary inclinations and our inclinations to help kin
  • In this sense, the norms of modern societies that make modern societies run now are at odds with at least some of our evolved instincts.
  • Lately we've been focused on the effects of religion
  • adherence to a world religion matters
  • People from world religions were willing to give more to the other person in the experiment, the anonymous stranger
  • Part of this is your willingness to acquire a norm of impartial roles; that we have a set of rules that governs this system.
  • political scientists call it the rule of law
  • those rules apply independently of the identities
  • If you want the rule of law to spread or to be maintained, you need conditions in which you're managing risk.
  •  
    [JOSEPH HENRICH:] The main questions I've been asking myself over the last couple years are broadly about how culture drove human evolution. Think back to when humans first got the capacity for cumulative cultural evolution-and by this I mean the ability for ideas to accumulate over generations, to get an increasingly complex tool starting from something simple. One generation adds a few things to it, the next generation adds a few more things, and the next generation, until it's so complex that no one in the first generation could have invented it.

Kim Peek, The Real Rain Man | Psychology Today - 0 views

  • Kim Peek, who lent inspiration to the fictional character Raymond Babbitt—played by Dustin Hoffman—in the movie Rain Man, was a remarkable savant.
  • He could read both pages of an open book at once, one page with one eye and the other with the other eye
  • He would retain 98 percent of the information he read.
  • ...9 more annotations...
  • Unlike many individuals with savant syndrome, Kim Peek was not afflicted with autistic spectrum disorder. Though he was strongly introverted, he did not have difficulties with social understanding and communication.
  • The main cause of his remarkable abilities seems to have been the lack of connections between his brain's two hemispheres. An MRI scan revealed an absence of the corpus callosum, the anterior commissure and the hippocampal commissure, the parts of the neurological system that transfer information between hemispheres. In some sense Kim was a natural born split-brain patient.
  • Michael Gazzaniga and Roger W. Sperry, the first to study split brains in humans, found that several patients who had undergone a complete calloscotomy suffered from split-brain syndrome.
  • the left hemisphere gives orders that reflect the person’s rational goal, whereas the right hemisphere issues conflicting demands that reveal hidden preferences.
  • Despite his brilliant mind, his IQ was 87, significantly below normal. It was also difficult for him to follow directions of certain kinds.
  • Kim Peek may have developed additional subcortical connections for information transfer.
  • Peek's ability to retain large amounts of information may have had something to do with another condition he was afflicted with called macrocephaly. This brain abnormality consists in an excessively large head and a correspondingly huge brain.
  • As a baby the real rain man was diagnosed with mental retardation and the physicians told his parents that he never would be able to read or talk.
  • Despite the recommendation, Kim’s parents chose to raise him at home.

    Adventures In Behavioral Neurology-Or-What Neurology Can Tell Us About Human Nature [V.S. RAMACHANDRAN:] I'm interested in all aspects of the human mind, including aspects of the mind that have been regarded as ineffable or mysterious. The way I approach these problems is to look at patients who have sustained injury to a small region in the brain, a discipline called Behavioral Neurology or Cognitive Neuroscience these days. Let me tell you about the problem confronting us. The brain is a 1.5 kilogram mass of jelly, the consistency of tofu, you can hold it in the palm of your hand, yet it can contemplate the vastness of space and time, the meaning of infinity and the meaning of existence. It can ask questions about who am I, where do I come from, questions about love and beauty, aesthetics, and art, and all these questions arising from this lump of jelly. It is truly the greatest of mysteries. The question is how does it come about?

  • In deciding when to eat, to work, to sleep, to rise, we stopped listening to our senses and started obeying the clock.
  • The Internet, an immeasurably powerful computing system, is subsuming most of our other intellectual technologies. It’s becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV.
  • The Net’s influence doesn’t end at the edges of a computer screen, either. As people’s minds become attuned to the crazy quilt of Internet media, traditional media have to adapt to the audience’s new expectations.
  • The Net’s intellectual ethic remains obscure.

  • The goal, as Taylor defined it in his celebrated 1911 treatise, The Principles of Scientific Management, was to identify and adopt, for every job, the “one best method” of work and thereby to effect “the gradual substitution of science for rule of thumb throughout the mechanic arts.”
  • In Google’s view, information is a kind of commodity, a utilitarian resource that can be mined and processed with industrial efficiency. The more pieces of information we can “access” and the faster we can extract their gist, the more productive we become as thinkers.
  • their easy assumption that we’d all “be better off” if our brains were supplemented, or even replaced, by an artificial intelligence is unsettling. It suggests a belief that intelligence is the output of a mechanical process, a series of discrete steps that can be isolated, measured, and optimized.

      I find this the most compelling argument. "Business" has an interest in selling things. Moving us faster, increasing our "seeking" instinct is one of the keys to this consumption frenzy. The individual needs to understand and manage these forces.

  • In the Zen Brain retreats, prominent scientists and Zen practitioners explore Buddhist, neuro-scientific and clinical science perspectives on topics like altruism, compassion and consciousness. Lectures and discussions with participants are embedded within zazen (meditation) practice throughout each day.
  • In these unusual programs, participants explore constructs like “affective stickiness,” a phrase coined by Dr. Richard Davidson, Research Professor of Psychology and Psychiatry at the University of Wisconsin-Madison. This is the phenomenon by which we interpret an experience as negative and then become so strongly identified with it that it becomes a fixed part of “us.”
  • The particular kind of misinterpreation of self-identification can prevent us from accessing our full range of consciousness and often limits our capacity to make choices regarding a situation.

Q&A: David Eagleman, Director, Initiative on Neuroscience and the Law | SmartPlanet - 1 views

  • David Eagleman is about as close to a rock star that a neuroscientist can be.
  • Eagleman was excited to talk to SmartPlanet about his work at both the Initiative on Neuroscience and Law, a national, interdisciplinary organization he founded that’s looking at how to remake the U.S. legal system; and the Laboratory for Perception and Action, at Baylor College of Medicine. The former initiative tackles topics such as how brain imaging and analyses of “Big Data” on crime patterns can help communities better understand and prevent violent behavior in new ways. The latter looks broadly at how individual brains are not at all alike — and how the differences might be significant for how we construct and manage our societies.
  • His work is particularly relevant in policy-related discussions in the aftermath of the Sandy Hook Elementary School tragedy in Connecticut.

  • “To the newsreaders who feel that mental illness is best viewed as an excuse, let me suggest instead that we might more effectually recognize it as a national priority for social policy,” he wrote on his blog shortly after the shootings.  “If we care to prevent the next mass shooting, we should concentrate our efforts on getting meaningful diagnoses and resources to the next Adam Lanza.”
  • Because we are able now to measure things we have never been able to measure before, this allows us potentially to customize sentencing and rehabilitation. The goal is to have the whole system be more just and have more utility.
  • Our system is built on the assumption that if you’re over 18 and over the IQ of 70, you’re a practical reasoner, free to choose how you act. But modern neuroscience suggests that those are not good assumptions.
  • I have to emphasize, though, that this is not about exculpation. I have to be very clear that this is really about customized sentencing and rehab that works.
  • It’s helpful to be able to talk about science in basic ways that anyone can understand. What I tell my students in my lab is that they need to be able explain their research to an 8th grader.
  • I’m an amateur history buff, and if I want to read about the Roman Empire, I don’t want to read an academic debate, but instead a narrative by a trusted guide who’s done their homework, who will offer the filter of how they understand the Roman Empire, to shepherd me through its history in only 200 pages.
  • Rather than “playful,” I’d say that my approach is simply the opposite of boring. It’s about looking for and then trying to answer questions that are poweful enough to get you out of bed at 5AM.
  • My intuition on this idea: being a good scientist or creative writer is about maintaining the wide-eyed wonder of a child and asking questions all the time. That’s what really makes discovery happen in any field.
  • Science is changing really rapidly. One way is that lots of scientists are moving into Big Data
  • Right now we’re involved with serious crunching to pull out statistical info on recidivism and crime. Our first challenge is visualizing it. So in this sense, creativity and art also relevant. Data visualization is really valuable stuff; you can discover a trend when you see, wow, I didn’t realize that bump would be there. To be able to tie together data in beautiful ways allows us to see and discover patterns.
  • I don’t have any fear about losing the mystery of creativity. If I explain every single chemical piece in the process of why you enjoy the taste of a soy latte, it wouldn’t diminish your enjoyment of a soy latte. It might even enhance it
  • Neuroscientists work on how to understand how brains construct reality in general, but we are in the position of fish trying to understand water. What I mean by that is that we only know one way of seeing the world very well, like a fish only knows water.  Learning about how synesthesia works allows us to get out of our fishbowl,
  • You don’t need to know anything about the brain to understand what shape or style will be appealing. We may come scrambling up behind advertisers and product designers and validate them. If Apple wanted to hire me, sure, I’d say yes immediately and do the best job I could! But honestly, they already know how to do it. They’re the design experts. We neuroscientists would in come with our fancy machines and theories and explain why what they do is already true.

  • Zull begins his journey with sensory-motor learning, and how that leads to discovery, and discovery to emotion. He then describes how deeper learning develops, how symbolic systems such as language and numbers emerge as tools for thought, how memory builds a knowledge base, and how memory is then used to create ideas and solve problems. Along the way he prompts us to think of new ways to shape educational experiences from early in life through adulthood, informed by the insight that metacognition lies at the root of all learning.

Theory of mind - Wikipedia, the free encyclopedia - 0 views

  • The emerging field of social neuroscience has also begun to address this debate, by imaging humans while performing tasks demanding the understanding of an intention, belief or other mental state.

      Mirror Neurons
  • The theory of mind (ToM) impairment describes a difficulty someone would have with perspective taking. This is also sometimes referred to as mind-blindness.
  • Individuals who experience a theory of mind deficit have difficulty determining the intentions of others, lack understanding of how their behavior affects others, and have a difficult time with social reciprocity.[27]
  • ...5 more annotations...
  • ToM deficits have been observed in people with autism spectrum disorders, schizophrenics, persons under the influence of alcohol and narcotics, sleep-deprived persons, and persons who are experiencing severe emotional or physical pain.
  • Research by Vittorio Gallese, Luciano Fadiga and Giacomo Rizzolatti (reviewed in [51]) has shown that some sensorimotor neurons, which are referred to as mirror neurons, first discovered in the premotor cortex of rhesus monkeys, may be involved in action understanding.
  • Neuropsychological evidence has provided support for neuroimaging results on the neural basis of theory of mind. A study with patients suffering from a lesion of the temporoparietal junction of the brain (between the temporal lobe and parietal lobe) reported that they have difficulty with some theory of mind tasks.[49] This shows that theory of mind abilities are associated with specific parts of the human brain.
  • However, there is also evidence against the link between mirror neurons and theory of mind. First, macaque monkeys have mirror neurons but do not seem to have a 'human-like' capacity to understand theory of mind and belief. Second, fMRI studies of theory of mind typically report activation in the mPFC, temporal poles and TPJ or STS,[54] but these brain areas are not part of the mirror neuron system.
    • David McGavock
       
      Contrary Mirror Neuron Evidence
  • The presumption that others have a mind is termed a theory of mind because each human can only intuit the existence of his/her own mind through introspection, and no one has direct access to the mind of another.

JOURNAL: Is Scanning and Situational Awareness a cure for Multitasking Drift? - Global ... - 0 views

  • If you are like me, you interact with a flood of information, online networks, and people everyday.  To handle it all, we multitask.  Unfortunately, it's easy to get off track or drift off course while multi-tasking.  
  • the act of multi-tasking -- responding to an e-mail/tweet/phone call, adding a new post/picture, etc. -- becomes an end in itself, rather than a means to an end.
  • How do you build a scan for online multitasking?  Build a checklist. List the online tasks you want/need to keep up with.    Organize the list from the most important task to the least.  Repeat important tasks in the list if the intervening tasks take you away too long from that important task. After you go through enough scans to clear the deck, take a break to work on items that require long term thinking.

  • Some people even drive their careers, businesses and lives off a cliff interacting with it.  They think they are getting things done, but they aren't getting anything done at all. The way to fight this is situational awareness. The little part of your brain that is ALWAYS asking you the questions: Where am I and what am I doing? Am I progressing towards my goal? Am I in any danger or is there a way to get to the goal faster?
  • A set of overarching goals that guide your behavior.  To apply this to online multi-tasking you need to train a part of your brain to ask these questions.
  • You can simulate that with: Asking a friend to lambast you every 10-30 minutes with these questions until you nail it every time.   Setting a random alarm that forces you to lift yourself out of your multi-tasking stupor to ask yourself these questions. Or, and this is the most difficult way, do your entire scan with intentional, conscious thought.  Justifying each and every step until it becomes second nature.

Multitasking, social media and distraction: Research review Journalist's Resource: Rese... - 0 views

  • researchers have tried to assess how humans are coping in this highly connected environment and how “chronic multitasking” may diminish our capacity to function effectively.
  • Clifford Nass, notes that scholarship has remained firm in the overall assessment: “The research is almost unanimous, which is very rare in social science, and it says that people who chronically multitask show an enormous range of deficits. They’re basically terrible at all sorts of cognitive tasks, including multitasking.”
  • Below are more than a dozen representative studies in these areas:

  • The researchers conclude that the experiments “suggest that heavy media multitaskers are distracted by the multiple streams of media they are consuming, or, alternatively, that those who infrequently multitask are more effective at volitionally allocating their attention in the face of distractions.”

The choices of which tasks to combine for multitasking were highly correlated across generations, as were difficulty ratings of specific multitasking combinations.
