  23. 23. “We feel quite truly that our wisdom begins with that of the author…By a law which perhaps signifies that we can receive the truth from nobody, that which is the end of their wisdom appears to us as but the beginning of ours.”“Nous sentons Marcel Proust tres bien que notre sagesse commence oucelle de l’auteur finit... “

  26. 26. 2. Can what we know about the Reading Brainillumine what we do not know about how reading and thought will develop in a digital culture ?
  27. 27. What are the deeper implications of having aplastic reading circuit as we move to a digitally dominated set of mediums ?
  28. 28. How do we think on-line?“The scariest thing about Stanley Kubrick’s vision wasn’t that computers started to act like people but that people had started to act like computers. We’re beginning to process information as if we’re nodes; it’s all about the speed of locating and reading data.We’re transferring our intelligence into the machine, and the machine is transferring its way of thinking into us.” Nick Carr in “Do you trust Google?”, WIRED, Jan. 2008
  29. 29. Cognitive characteristics of on-line reading in the digital reading brainContinuous partial attention; less sustained attention and focus“Set” for immediacy and speed of processingFaster multi-tasking of large sets of information 37
  30. 30. Differences in Attention: “Skimming is the newnormal”Scanning, browsing, bouncing, keyword spotting (Liu,2005, 2009)Less time on in-depth, concentrated readingPsychological reflex to “click” and move “set”Decreased sustained attention
  31. 31. More attention tovisual, external imageryLess emphases ontouch and materialityLess internalization ofknowledge, and moredependence on externalsources
  32. 32. Cognitive Effects of Multi-tasking: Brain Imaging Studies Brain Imaging Studies“Even if we can learn while distracted,it changes how you learn, makingthe learning less efficient and useful” “Multitasking hinders learning” Russ Poldrack (2006) Proceedings from National Academy of Science
  33. 33. Touch and Materiality Factors: Kinesthesia and Synesthesia Emphases in Screen and Print“Near impossibility of getting immersed in hypertext in same way as getting lost in a book” (Mangen, 2009)
  34. 34. Comprehension for On-Screen vs. PrintScreen Print (Ackerman & Lauterman, 2012)
  35. 35. The Formation of Deep ReadingHow does deep reading come to be?
  36. 36. Cautions From the Last Transition Socrates feared that print would give the illusion of truth and create no ambition in the young beyond the superfluity of knowledge .
  37. 37. Is superfluity (“shallow reading”)and the expectation for constant,immediate external information bethe new threat for digital readers? Will these emphases short-circuit the reading brain?
  38. 38. Will the process of internalization of knowledgerequire too much time and cognitive effort given immediateaccess to external knowledgeWill imagination in childhood be displaced by too muchthat is given too quickly requiring too littleeffort ?Will the development of imagery in the child bedisplaced by visual imagery that is provided
  39. 39. We can not go back to apre-digital time; but, weshould not lurch forward without understanding what we will lose ,what we will gain , for our species’ cognitive repertoire.
  40. 40. “It would be a shame if brilliant technology were to end up threatening the kind of intellect that produced it.” - Edward Tenner
  41. 41. Three Questions of Kant (Dunne, 2012) What can we know? What should we do? What may we hope ?
  42. 42. 3. Can knowledge about the “reading brain”, combined with multiple ways of knowing ---exemplified bySocrates/Aristotle, Proust, and Nicholas of Cusa--- propel a more hopeful approach to our transition?
  43. 43. How do we prevent “Shortcircuiting” of deep reading brain while acquiring new skills necessary for the 21st Century?
  44. 44. “A culture can be judged by how it pursues three lives: the life ofactivity and productivity, the life of enjoyment, the life of contemplation.” -Aristotle
  45. 45. ➡ Massive information processing with more non-linear branching and iconic emphases Advantages of Digital Reading ➡ Speed and efficiencyBrain for the Life ➡ Multi-tasking and of Activity and interactive communication Productivity ➡ Democratization of knowledge
  46. 46. One of the greatest impediments to this form of reading is the “busy mind” thatskips from one thoughtto the next without the capacity to enter thehidden depths of words that require both receptivity and thequiet focusing of attention. -Enzo Bianchi
  47. 47. Advantages of DeepReading Brain for the “Life ofContemplation”The timerequired by deep reading both in milliseconds during the reading actand in years of formation changes the quality of thought.
  48. 48. “We transgress notbecause we try to build the new, but because we do not allow ourselves to consider what it disrupts or diminishes” -Sherry Turkle, Alone Together
  49. 49. How do we resolve a “coincidence of opposites of believable truths”? -Nicholas of Cusa
  50. 50. “learn-ed ignorance”A kind of knowing that is aware of its own limits: what we know what we do not knowand what we need to know to understand and move forward. to understand and move forward.
  51. 51. What we know...
  52. 52. We know...... our brain was never genetically programmed to read.
  53. 53. We know... ... each reader must build a new reading circuit.
  54. 54. We know...... this reading circuit is plastic and influenced by the specific emphases of different writing systems and mediums
  55. 55. We know...... that the present reading brain is capable of both the most superficial and the deepest forms of reading, feeling, and thought
  56. 56. What we do not know...
  57. 57. We do not know...... but we can predict that information will accelerate atrates that will make completely new demands on every person in the next generation. Courtesy of Ray Kurzweil and Kurzweil Technologies, Inc.
  58. 58. We do not know......if immediate access to massive amounts of information will change the nature of internal processing during reading--- its deeper comprehension and the internalization of knowledge for future thoughts and insights beyond information given.
  59. 59. We do not know...... if the immediate access to this increasing amount of external information in the young will deter from the formation of “Deep Reading” processes or the desire to probe more deeply into its meaning or to go beyond it.
  60. 60. We do not know...... if such changes in internalized knowledge will result ina very different set of cognitive capacities to synthesize,infer from information, and go beyond it in very different,and more innovative ways than before, more appropriate for the digital culture.
  61. 61. Three Questions of Kant (Dunne, 2012) What can we know? What should we do? What may we hope ?
  62. 62. “I think there’s acommon point between both worlds, and then there’s also a point of departure where theyeach demonstrate their own sort of possibilities.” -Mark Danielewski
  63. 63. QuickTime™ et un décompresseursont requis pour visionner cette image.
  64. 64. How do we add to the repertoire of the expert“Knowing what we reading brain withoutdo not Know” diminishing its present capacities?as the basis for ourQuestions How can the digital medium be designed to redress its own shortcomings?
  65. 65. How can we create the conditions for new readers todevelop a bi-literate brain and to know whento skim and when to dive deeply?
  66. 66. A lecture about how the brain learns to leapbeyond the information given shouldn’t have a last slide.....
