  1. Good afternoon.
  2. My name is Megan. And today I will be discussing visual perception
  3. and the pilot profession.
  4. The basic principles of visual perception can be seen through
  5. the lens of the organizational principles of just saw perception.
  6. In short, the principles are similarity, proximity,
  7. good continuation,
  8. closure
  9. and simplicity.
  10. Similarity
  11. is the similarity in which objects are grouped.
  12. Proximity is another way in which objects are grouped in a scene.
  13. Good continuation refers to the way in
  14. which objects are perceived as continuation.
  15. In cases where they are expected to continue
  16. closure is when an object is perceived as a whole, even when parts are missing.
  17. And simplicity is when objects are perceived in the simplest way possible
  18. as discussed in this week's module overview.
  19. Visual perception is important for everyday life because it allows
  20. us to carry out necessary tasks on a daily basis.
  21. Our body and environment influence the way our visual processes perceive
  22. objects.
  23. The visual reality that we experience is
  24. created by our brain's cognitive processes.
  25. As a result damage in the brain or visual processes
  26. could result in changes to the person's visual perception,
  27. to pilots. Optimal visual perception is vital to control and operate any aircraft
  28. pilots benefit from the computational approach to perception,
  29. which allows individuals to use cues in visual stimuli to help determine
  30. and estimate the size and distance of objects.
  31. When interpreting scenes through visual stimuli. It is important to
  32. for pilots to be able to determine distance and size of objects.
  33. Despite them being far or close in distance from the plane.
  34. Furthermore,
  35. pilots must maintain optimal environment and
  36. mental stability because these are influencers
  37. of visual perception and can hinder their ability to conduct the aircraft.
  38. The first theory is the theory of unconscious inferences,
  39. which suggests that when we are perceiving the world,
  40. we are also making unconscious inferences.
  41. We use top down
  42. processing unconsciously to perceive and interpret the environment.
  43. Top down processing is essentially the use of cognitive processes that
  44. begin with our thoughts and flow down to lower level functioning.
  45. In this case, vision
  46. unconscious inference is beneficial.
  47. But needing to estimate the overall picture.
  48. For example, when flying a plane,
  49. the landing may be obscured partially by fog or distance.
  50. Unconscious inference allows pilots to perceive that there is
  51. an entire landing ahead rather than the partial landing
  52. area.
  53. This can become a weakness if the perception of the unconscious inference
  54. is incorrect and the entirety of the scene is not as expected.
  55. For example,
  56. if the pilot determines that the landing area is large enough and
  57. is only obscured due to fog or distance and they are wrong,
  58. this could potentially be a fatal mistake
  59. in our visual perception.
  60. There are gaps in our ability to see
  61. in extremely far distances in poor weather conditions,
  62. in poor mental and physical health
  63. or
  64. through objects, through physical objects
  65. to compensate our brains use unconscious inference to infer our visual reality.
  66. In some cases, this perception is wrong
  67. to improve cognitive function and the likelihood that pilots land safely,
  68. landing areas are equipped with red beaming lights
  69. to signal where the landing area is and how far it stretches.
  70. This can be visible from far distances and in poor
  71. weather conditions and gives pilots a better way of unconsciously inferring
  72. the landing zone.
  73. Furthermore, to improve cognitive function,
  74. pilots should strive to remain physically and mentally healthy
  75. to perform to the best of
  76. their capability.
  77. Also as discussed earlier,
  78. ensuring that the environment is optimal will improve visual perception as well
  79. such as clear weather.
  80. The second theory is computational approach,
  81. this theory explains the object recognition is based on
  82. features of these objects which are known as Geon
  83. Geon are three dimensional pieces of objects
  84. which we first identify when we perceive objects
  85. as stated in the textbook,
  86. we then match the Geon we perceive against representations of
  87. objects stored in memory to identify the whole object.
  88. One process which is significant to discuss is the use
  89. of basic cues in the environment which allows the stimuli
  90. that is being presented to be interpreted.
  91. There are weaknesses in our visual abilities,
  92. some of which being able to clearly see objects in
  93. a distance and see objects in less than optimal settings.
  94. The computational approach allows individuals to
  95. recognize objects using their basic shapes.
  96. This can be used as a strength for both pilots
  97. and survival because often objects in far distance or
  98. important environments for seeing could become blurred and obscured,
  99. only showing their geon
  100. by being able to identify geon and relate them to objects we
  101. already have stored in our memories,
  102. we can perceive objects based on their three dimensional shapes.
  103. The computational approach is beneficial for
  104. estimating size and distance to compensate for
  105. the gap in our ability to interpret a scene in any given condition.
  106. We are able to estimate
  107. some improvements that pilots should make in their cognitive function
  108. is the ability to recognize objects using three dimensional fingers.
  109. They should also practice doing so under multiple conditions in a
  110. controlled environment such as a simulator to simulate fog and rain.
  111. This concludes my presentation. Thank you for your time.
