57. FINAL JEOPARDY CATEGORY Sensational Senses

58. Correct Answer When a stimulus is unchanging, our neurons fire less frequently, and we stop responding to the stimulus.

59. 100 Back to board C1 - 100 What is: Vestibular sense?

60. What is: Perception? (Perception is the process of interpreting sensations and giving them meaning. So even though you and your friend are “seeing” the same stimulus, your interpretations are different.) Back to board C1 - 200 200

61. Back to boardboard C1 - 300 300 What is: Kinesthesis?

62. Back to board C1 - 400 400 What is: Cochlea?

63. Back to board C1 -500 500 What are: Synesthesia? (Apparently this is due to some people have an atypically large number of connections between brain areas that process different senses. Imagine feeling a sound, or tasting a picture!)

64. Back to board C2 - 100 100 What is: Absolute thresholds? (Dogs have sound receptors that can pick up higher frequency sounds than do humans. This means that dogs have a lower absolute threshold for sound than do humans. That is, dogs’ sound receptors are more sensitive. Give yourself credit for any related explanation. )

65. Back to board C2 - 200 200 What is: Difference threshold?

66. Back to board C2 - 300 300 What is: Sensory Adaptation?

67. Back to board C2 - 400 400 What is: Cocktail Party Effect?

68. Back to board C2 -500 500 What is: Selective Attention?

69. Back to board C3 -100 100 What is: Young-Helmholtz trichromatic ( 3 color) theory?

70. Back to board C3 -200 200 What are: Red-Green Blue-Yellow White-Black

71. Back to board C3 -300 300 What is: Feature detectors?

72. Back to board C3 -400 400 What is: Gate-control theory of pain?

73. Back to board C3 -500 What is: Signal detection theory? (According to this theory, when we try to measure the sensitivity of human senses we are not only measuring the ability to detect a sense. We are also measuring a person’s decision about whether or not they think they detected a stimulus.) 500

74. Back to board C4 -100 100 What is: The lens?

75. Back to board C4 -200 200 What is: The cornea?

76. Back to board C4 -300 300 What is: The iris?

77. Back to board C4 -400 400 What are: The pupil? (The iris controls the size of the pupil.)

78. Back to board C4 -500 500 What is a: Blind spot? (There are no light receptors (cones or rods) at this location.)

79. Back to board C5 -100 100 What is: The retina?

80. Back to board C5 -200 200 What are: Cones?

81. Back to board C5 -300 300 What is: Rods?

82. Back to board C5 -400 400 What is: Transduction?

83. Back to board C5 -500 500 What is: Sensorineural Hearing Loss?

84. Back to Board C6 -200 200 What is: Retina?

85. Back to Board C6 -400 400 What is: cones? (These light receptors allow for the perception of color. It’s more accurate to say you’d see the world not only in black and white, but also as a series of grays. )

86. Back to Board C6 -600 600 What is: rods?

87. Back to Board C6 -800 800 What is: fovea?

88. Back to Board C6 -1000 1000 Who is: Ganglion cells?

89. Back to Board C7 -200 200 What is: Trichromatic color theory? (red – long wavelengths, green – medium wavelengths, blue – short wavelengths)

90. Back to Board C7 -400 400 What is: Opponent process theory? (When pairs of cells are antagonistic or opponents, when one cell is firing, the other one cannot fire. Thus if the cell sensitive to red is firing, the green cell cannot fire – so we can’t perceive a reddish green.)

91. Back to Board C7 -600 600 What is: Similarity? X 0 X For example, most people describe the array at the left as a column Xs, column of 0s, column of Xs. That is, tend to see similar objects as grouped.

92. Back to Board C7 -800 800 What is: Gestalt? (The Gestalt psychologists studied form and shape perception.)

93. Back to Board C7 -1000 1000 Feature detectors? (For example, some cells in the visual cortex only respond or fire when a horizontal line is part of the visual stimulus. Some cells only respond to vertical lines.)

94. Back to Board C8 -200 200 What is: Monocular?

95. Back to Board C8 -400 400 What is: Shape constancy?

96. Back to Board C8 -600 600 What is: Retinal disparity?

100. Back to Board C9 -400 400 What is: Sweet Salty Sour Bitter?

101. Back to Board C9 -600 600 What is: Critical period? (For example, if a person is born blind and his or her sight is corrected during about the first nine months of life, that person is likely to develop normal sight. If the cause of the blindness is corrected later, however, when the person is older, he or she may recover some abilities, but probably won’t see normally.)

102. Back to Board C9 -800 800 What is: Top-down processing? (bottom-up processing is taking the pieces of the puzzle to understand)

103. Back to Board C9 -1000 1000 What is : Perceptual set? (Our perceptions can be affected by our expectations and by our habitual ways of perceiving. We expect sentences not to have repeated words, so we may overlook them when they appear. )

104. Back to Board C10 -200 200 What is: subliminal? (There is evidence that simple visual stimuli that you are exposed to so briefly that you aren’t aware of it, can affect your behavior. There is not support for the idea that more complex information is effective if presented at a subliminal level. )

105. Back to Board C10 -400 400 What are: Parapsychology? (Some research by parapsychologists has been criticized for not being well designed and not properly testing ESP claims.)

106. Back to Board C10 -600 600 What is: NO? (There is no evidence that such tapes work.)

107. Back to Board C10 -800 800 What is: Telepathy? (This is a form of ESP or extrasensory perception. There is no reliable evidence that any person has this ability.)

108. Back to Board C10 -1000 1000 What is: She was peeking? (For example, she could only identify objects that were held low – where she could see them if she was peeking from under the blindfold. Her tricks only worked when she wore the blindfold her “teacher” gave her.)

109. Final Jeopardy (For example, you may get used to the smell of the fish you had for dinner and no longer notice it.) What is Sensory adaptation?
