TEDxRheinMain - Prof. Dr. Thomas Metzinger - The Ego Tunnel - YouTube - 1 views

  •  
    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

Tamir DI, Mitchell JP. Disclosing information about the self is intrinsically rewarding. - 0 views

    Tamir DI, Mitchell JP. Disclosing information about the self is intrinsically rewarding. Department of Psychology, Harvard University, Cambridge, MA 02138, USA. dtamir@fas.harvard.edu Abstract Humans devote 30-40% of speech output solely to informing others of their own subjective experiences. What drives this propensity for disclosure? Here, we test recent theories that individuals place high subjective value on opportunities to communicate their thoughts and feelings to others and that doing so engages neural and cognitive mechanisms associated with reward. Five studies provided support for this hypothesis. Self-disclosure was strongly associated with increased activation in brain regions that form the mesolimbic dopamine system, including the nucleus accumbens and ventral tegmental area. Moreover, individuals were willing to forgo money to disclose about the self.

    "Synthetic Biology promises low-cost, exponentially scalable products and global health solutions in the form of self-replicating organisms, or "living devices." As these promises are realized, proof-of-concept systems will gradually migrate from tightly regulated laboratory or industrial environments into private spaces as, for instance, probiotic health products, food, and even do-it-yourself bioengineered systems. What additional steps, if any, should be taken before releasing engineered self-replicating organisms into a broader user space? In this review, we explain how studies of genetically modified organisms lay groundwork for the future landscape of biosafety."

Will Power: You Grow With The Task -- Ingenious Monkey - 20 two 5 - 0 views

  •  
    Following Baumeister et al.'s widely cited work on self-regulation, many psychologists view will-power as a depletable resource. According to this view, whenever we perform acts of self-regulation (e.g. resisting a delicious piece of cake) we tap into our individual will-power reservoir (think of it as a bank account), and thereby reduce the amount of will-power left for subsequent tasks. According to a study published in the Journal of Applied Psychology, however, this plausible intuition does not necessarily seem to hold true entirely.

They may also be overconfident and underestimate the risks involved in reckless driving.Those who admit to aggressive driving also admit to engaging in more incidents of breaking the law.A sense of being under time and pressure leads to more aggressive driving.

Grassroots Nanotech: Controlled Self-Assembly - 0 views

    Throughout our history, mankind has created tools the same way, essentially using the top-down approach. Think about it. In the stone age, a sharp cutting tool was fashioned by using a larger stone to chip away pieces until the cutting stone was sharp enough. Today, a computer chip is made by a large laser that etches the circuits into a piece of silicon.

Michael Lewis: Obama's Way | Vanity Fair, AUTOPILOT - 0 views

  •  
    ""You'll see I wear only gray or blue suits," he said. "I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make." He mentioned research that shows the simple act of making decisions degrades one's ability to make further decisions. It's why shopping is so exhausting. "You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia." The self-discipline he believes is required to do the job well comes at a high price. "You can't wander around," he said. "It's much harder to be surprised. You don't have those moments of serendipity."
