  1. Bekesy, G.
    Traveling wave theory
  2. Berkeley, G.
    Depth cues
  3. Broadbent, D
    Filter theory of attention
  4. Gibson, E & Walk, R
    Visual cliff
  5. Hering, E - opcv
    Opponent process of color vision
  6. Hubel, D & Wiesel, T - s,c,hc
    Feature detection in visual cortex;

    discovered simple (orientation and boundaries), complex (advacned info - movement), and hypercomplex cells (abstract concepts like object shape)
  7. Kohler, W
    Isomorphism
  8. Melzack, R & Wall, P
    Gate theory of pain
  9. Swets, John
    ROC curves in signal detection theory
  10. Wever, E & Bray, C
    Volley theory of pitch
  11. Yerkes, R & Dodson, J
    • Yerkes-Dodson law:
    • Performance is best at intermediate level of arousal
  12. Weber, Ernst
    Just noticebale difference:
  13. CPILR
    • parts of the eye:
    • Cornea
    • Pupil
    • Iris
    • Lens
    • Retina
  14. Cells in the retina - C R A RGC ON ONF
    • Cones - color and fine detail
    • Rods - perceive achromatic cells, low sensitivity to detail, no color vision, functions best in reduced illumination
    • Bipolar cells - connect cones and rods
    • Amacrine cells
    • Retinal ganglion cells. - form optic nerve
    • Optic nerve fibers
  15. optic chiasm
    Where fibers from Nasal half of retina cross paths
  16. Path of auditory info - OC LGN(t) VC(o) SC
    • Optic Chasm
    • Lateral Geniculate Nucleus (thalamus)
    • Visual Cortex (occipital lobe)
    • Superior colliculus
  17. Perceived brightness - a, sb, li
    Adaptation - your eyes adapt to bright And dark environments

    SimultAneous brightness contrast - stimulus Ppears brighter when compared to. Darker object

    LaterL inhibition - adjacent retinal cells inhibit one another
  18. ROYGBIV
    • Colors of the spectrum:
    • Red
    • OrAnge
    • Yellow
    • Green
    • Blue
    • Indigo
    • Violet
  19. Primary colors
    • Red
    • Blue
    • Green, not yellow
  20. Trichromatic theory Y/H
    • Young-Helmhotz theory:
    • The retina contains three differrent types of color receptors (cones) which Re differentially sensitive to different colors
  21. Hering's criticism of trichromatic theory
    Yellow is a primary color

    • Opposing pairs:
    • Red-green
    • Blue-yellow
    • Black-white
    • (opponent process theory of color vision)
  22. Depth cues - I/O S LP TXG MP BD/S
    • Interposition/overlap
    • Relative size
    • Linear perspective
    • Texture gradient
    • Motion parallax
    • Binocular disparity/stereopsis (requires 2 eyes)
  23. perception of form
    Figure (object at center of attention) and ground (background)
  24. 5 laws of perception - PSCCP
    • Proximity
    • Similarity
    • Good continuation
    • Closure
    • Pragnanz
  25. Bottom-up processing
    Perception of components and then entire object

    (data drivem)
  26. Top-down processing
    Object perception guided by conceptual processes (memories and expectations)

    Recognize whole object and then components
