  1. Hi my name is Ann Reid and I have really enjoyed this semester and sensation and
  2. perception and yeah I'm excited to talk about
  3. my favorite thing that I've learned thus far.
  4. Um I feel like I've learned a lot this semester
  5. and I found this class to be super interesting and
  6. um yeah it made me think about things in a
  7. different way and I realized things that I had never
  8. really known before and this
  9. my favorite thing that I've learned I think is
  10. Um it's in chapter 10 which is called perceiving depth and size.
  11. I found um the illusions specifically entertaining for me.
  12. Um That was one of my main favorite things this semester in
  13. general where the visual illusions and more specifically the depth illusions.
  14. Um Yeah thinking about the illusions that our brain tricks us into thinking our
  15. reality which is super fascinating to me and I loved learning about it.
  16. So
  17. the first one that I wanted to talk about is the Mueller liar illusion.
  18. Um As you can see the second line appears longer than the first,
  19. even though there at the exact same length.
  20. Um
  21. Yeah, so why does this happen?
  22. The psychologist Richard Gregory explained by using an
  23. idea called the misapplied size Constancy scaling,
  24. which means that when ways of maintaining size constancy in the three D.
  25. World are applied when looking at two D.
  26. Photos, a size illusion can occur, which I thought was super cool.
  27. Um Another theory called the conflicting cues theory
  28. which was proposed by Rh day,
  29. says that our perception of line length depends on two things.
  30. So the first one being the actual length of the line and
  31. then the second one being the overall length of the figure,
  32. which makes really a perfect sense from looking at this because
  33. obviously the second
  34. line is the same size, but the figure is bigger. So that's
  35. why our brain thinks that um
  36. The 2nd 1 is longer.
  37. The next one that I like to learn about is the ponzu illusion.
  38. So this is also called the railroad track illusion.
  39. It's because um it happens when there are converging
  40. lines and the second line appears larger because it
  41. appears farther away and our depth perception gets messed
  42. up a little bit when looking at this.
  43. So even though they're the exact same line,
  44. we think that the one further away is bigger
  45. um
  46. just because it's not actually further away,
  47. obviously it just appears further away.
  48. Um
  49. So yeah,
  50. and then the third one that I really liked is the Ames room illusion.
  51. So this has to do with just the build of a room.
  52. So these two girls are the exact same size, but um
  53. they won obviously the one on the right appears a lot larger just due to
  54. the makeup of the room and how we're looking at this room in the photo.
  55. Um
  56. So I think that one's super interesting and then the last one is the moon illusion, so
  57. the moon always looks bigger when it's on the horizon. So the farther away moon,
  58. obviously it looks a lot bigger than the one on the railroad track because um
  59. our brain tricks us into thinking that the moon on the horizon would be bigger.
  60. So I thought that was super cool as well. I love I love learning about the illusion. So
  61. in conclusion I just wanted to say thank you for a great semester.
  62. I really enjoyed learning a lot.
  63. And yeah,
  64. I wish you the best of luck and I look forward
  65. to maybe taking another class with you again in the future.
  66. Thanks so much.
