  25. detailed internal representation

  26. sparse ???

  27. Why do we think we see “everything”? • Immediate availability at flick of eye/attention • The “world as an outside memory”(O’Regan, 1992) • refrigerator light analogy (N. Thomas) • visual “solipsism” • vividness through transients

  28. Why we think we see everything • Refrigerator light analogy (N. Thomas) • seeing is having access

  29. Yarbus, 1978
