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.

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.

Confessions of an Aca/Fan: Archives: A New Culture of Learning: An Interview with John ... - 1 views

  • Today, I want to call attention to a significant new book, A New Culture of Learning: Cultivating the Imagination for a World of Constant Change, written by two of my new colleagues at the University of Southern California -- Douglas Thomas and John Seely Brown.
  • John Seely Brown and Douglas Thomas lay out a step by step argument for why learning is changing in the 21st century and what schools need to do to accommodate these new practices.
  • My hope is that our schools will soon embrace the book's emphasis on knowing, making, and playing.

  • The fear is easy to understand. What we are essentially doing when we move to student-directed learning is undermining our own relatively stable (though I would argue obsolete) notions of expertise and replacing them something new and different.
  • One of the key arguments we are making is that the role of educators needs to shift away from being expert in a particular area of knowledge, to becoming expert in the ability to create and shape new learning environments.
  • how do we identify the narrowing range of content which probably does fall into this category and which provides a common baseline for other kinds of learning?
  • users are not so much creating content as they are constantly reshaping context.
  • The very idea of remix is about the productions of new meanings by reframing or shifting the context in which something means.
  • You challenge here what James Paul Gee has called the "content fetish," stressing that how we learn is more important than what we learn. How far are you willing to push this? Doesn't it matter whether children are learning the periodic table or the forms of alchemy practiced in the Harry Potter books? Or that they know Obama is Christian rather than Muslim?
  • throughout the book, we stress that knowledge, now more than ever, is becoming a where rather than a what or how.
  • The explicit is only one kind of content, which tells you what something means.
  • The tacit has its own layer of meaning. It tells why something is important to you, how it relates to your life and social practices.

    "Presented at the University of Manitoba June 17th 2008. (for those of you waiting for the Library of Congress presentation, it will be posted Jul16 videos of the work of Michaerl Welsch in Cultural Antropology classes on media litteracy..; a fantastic and incredibly powerfiull showpiece on how education can become with at the same time hints on what to-morrow could look like..; 19th-ish.) From Stephen's Lighthouse: http://stephenslighthouse.sirsidynix.com/archives/2008/07/michael_wesch_l.html" "Many of you have probably seen Kansas State University prof Michael Wesch's thought-provoking video, "A Vision of Students Today". http://www.youtube.com/watch?v=dGCJ46vyR9o. Recently Dr. Wesch spoke at the University of Manitoba where he explained the the basis of this video in a talk entitled, "Michael Wesch and the Future of Education." I found it fascinating! He describes how he so naturally incorporates emerging technologies into his courses from the smallest seminar type class to the largest lecture theatre filled class. More importantly he not only talks about the technologies but how he encourages extraordinary participation and collaboration from his students by engaging them in meaningful learning activities. Although the video is 66 minutes long...pour a coffee, iced tea or glass of wine and enjoy this dynamic presentation from a master teacher." http://umanitoba.ca/ist/production/streaming/podcast_wesch.html Dubbed "the explainer" by popular geek publication Wired because of his viral YouTube video that summarizes Web 2.0 in under five minutes, cultural anthropologist Michael Wesch brought his Web 2.0 wisdom to the University of Manitoba on June 17. During his presentation, the Kansas State University professor breaks down his attempts to integrate Facebook, Netvibes, Diigo, Google Apps, Jott, Twitter, and other emerging technologies to create an education portal of the future. "It's basically an ongoing experiment to create a portal for me and my stud

Shame and honour drive cooperation - 0 views

  • Shame is a traditional deterrent from asocial behaviour and is employed when offenders are singled out for public scorn.
  • Modern democratic societies have moved away from including the public in the punishment, although in some cases (e.g. drunk driving licence plates) the state still sanctions shame [1].
  • shame as well as honour could become more prevalent as digital technology
  • ...15 more annotations...
  • We designed this public goods experiment to isolate the effects of being shamed or honoured, with no monetary consequences to either experience, and test whether the expectation of negative or positive reputational information enforces social behaviour.
    • David McGavock
       
      Point of the study
  • If players know that only the least or most cooperative individuals are to stand in front of their peers, will they cooperate more as a group?
  • In games that offer players anonymity, uncooperative behaviour is more prevalent [7] while the opposite is true of games in which players know that each of their decisions will be linked to their real identities [8–10]
  • confirming that, even when only the least or most cooperative individuals are to stand in front of their peers, players cooperate more as a group
  • expected that shame might be more effective than honour
  • n contrast to our expectations, we found no significant differences in group contributions over the first 10 rounds between the shame and honour treatments.
  • We hypothesized that the threat of shame or the prospect of honour would lead to increased public contributions.
  • Our results show that a promise to single out free-riding individuals for public scrutiny can lead to greater cooperation from the whole group, as can singling out the most generous individuals.
  • Group cooperation in the shame treatment significantly declined following round 10 (paired t-test between 10th and 12th round, t = 3.67, p = 0.005), corroborating our finding that the threat of being singled out as a free rider had been driving cooperation.
  • Cues of being watched enhance cooperation [11] and when humans lived in small groups, it was easy to observe individual behaviour.
  • language, replaced direct observation
  • the absence of shaming by the state does not preclude the absence of shame altogether in society, especially as social media increases the frequency, speed and inclusiveness of communication.
  • The Internet increasingly creates a global town square where controls are harder to implement and enforce, gossip travels fast, and where shame as well as honour therefore might experience resurgence.
  • Transparency also enhances cooperation [8–10] but can be costly to provide and its use can be limited. Transparency requires time evaluating and determining a satisfactory performance.
  • difficult in our current era, where human attention, not information, is a scarce resource [15].
    • David McGavock
       
      Interesting distinction; that attention is in shorter supply than information.
