  1. Scene perception after those first few hundred milliseconds Jeremy Wolfe Brigham and Women's Hospital and Harvard Medical School

  2. The constructive view of scene perception

  3. The constructive view of scene perception

  4. The constructive view of scene perception

  5. The constructive view of scene perception Appealing…but wrong

  6. The transient binding view of scene perception

  7. The transient binding view of scene perception

  8. The transient binding view of scene perception

  9. The transient binding view of scene perception

  10. The transient binding view of scene perception

  11. The transient binding view of scene perception

  12. If you want to know what is here ?

  13. You will have to check

  14. What is the evidence for this claim? The repeated search task • The capital letters are the search array. • The lower case letter at the center tell you what to look for on this trial. • In repeated search, the search array does not change from trial to trial.

  15. Slope of the RT x set size function is the measure of search efficiency

  16. SLOPE

  17. SLOPE

  18. Actually, only 2AFC memory search is efficient Localization responses Melina Kunar’s mouseclick experiments. (Kunar, Flusberg, & Wolfe)

  19. But this is a meeting about scenes So Aude and I did a version with scenes like this

  20. Same basic result Unrepeated Repeated Note: Mean RT is faster, but search efficiency is unchanged.

  21. We also did “panoramic” search

  22. Panorama Experiments

  23. Panorama Experiments

  24. Panorama Experiments

  25. Panorama Experiments

  26. Panorama Experiments

  27. Panorama Experiments

  28. Panorama Experiments

  29. You can search for a visible target You still get a slope

  30. If the same target is hidden The slope can vanish

  31. Subjects make a pragmatic choice Search if the target is visible

  32. The “IsWas” Paradigm Minimal Change Blindness

  33. Behold, I bring you a mystery. Does the cued dot change color?

  34. No

  35. No

  36. Yes

  37. No

  38. So…to summarize

  39. and subsequent awareness with an attentional bottleneck feeding object recognition A selective pathway

  40. Access to the bottleneck is controlled byguiding representation.

  41. A non-selective pathway can fill in the rest of the experience
