  9. For what scientific experiment did David Hubel and

    • Putting the head of a slightly anesthetized cat into a vice so that it’s forced to watch a simple slide show while you poke the back of its brain with a
    • microelectrode. Provided clues to how the brain sees images provided by our eyes.
  10. According to researchers, the brain responds
    quickly and easily to what four major attributes of all viewed objects?
    • Color,
    • form, depth, and movement.
  11. What British physician was the first to link color
    and the human eye? In what year did he do this?
    Thomas Young, 1801.
  12. In 1851, German physiologist and physicist Hermann

    • Objective: or scientific, describes colors rests on the
    • assumption that the perception of color is a result of various light
    • wavelengths stimulating the cones along the back of the eyes’ retinas.
    • Comparative: the color that another
    • color is compared with must be accepted universally as a standard
    • Subjective: most symbolic, a person’s mental state or
    • association with an object strongly affects the emotional response to a color

  16. According to researchers, what are the 8 factors
    which work singularly or in combination to give viewers a sense of depth?
    • Space, size, color, lighting, textural gradients,
    • interposition, time, and perspective.
  17. Of the 8 factors that give viewers a sense of
    depth, which is the most complex? Why?
    • Perspective; because it is equal parts brain
    • function and learned behavior.
  18. What are the 4 types of movement? Understand and be
    able to give an example of each.
    • Real:
    • motion not connected with an mage presented in the media. Actual movement a
    • seen by a viewer of some other person, animal, or object
    • Apparent: example, motion picture
    • films. A series of still images put together sequentially for film, videotape,
    • or digital media and moved through a viewing device at a fast speed.
    • Graphic: the motion of the eyes as
    • they scan a field of fiew or the way a graphic designer positions elements so
    • that the eyes move throughout a layout. An eye will usually follow a line, a
    • slow curve, or a horizontal shape before it follows other graphic elements.
    • Another example is magazine covers.
    • Implied: motion that a viewer
    • perceives ina still, single image witout
    • any movement of an object, image, or eye. Visual vibration (frenetic, pulsating
    • results from optical or “op” art)
