  1. More Studies in Optical Illusions You have a list of the concepts we discussed in the chapter. Can you apply the concepts to explain the illusions?

  2. How does LIFT become noticeable? • In the first slide, the white edges suggests that the background is white. We presume the black objects are the foreground. • This is a figure-ground issue.

  3. Our expectations from past experience affect what we see. • We are not accustomed to seeing writing positioned at an angle. As a result, most of us see the figure instead of the word at first.

  4. Gestalt principle of closure

  5. Muller Lyon Illusion Which line segment is longer?

  6. Look at the Muller Lyon lines in the picture. It is believed that we judge the one line to be longer because it corresponds to our familiar images of edges of buildings. (Could it also be an instance of closure?)

  7. Who is standing behind President Clinton?

  8. It is not Al Gore. • It is another photo of Clinton. • This is an example of context affecting our perception.

  9. This image is an illusion because it tricks our concept of light and shadow affecting depth.

  10. Extrasensory perception? • Telepathy – mind reading • Clairvoyance –”seeing” remote events • Precognition – Knowing things before they happen

  11. Any credible evidence for ESP? • While most parapsychology labs have shut down due to inability to find evidence supporting ESP, Daryl Bem, a prominent social psychologist, has published a literature review in a reputable research journal which lends some support to the existence of “psi”. • Bem, D. J., & Honorton, C. (1994). Does psi exist? Replicable evidence for an anamolous process of information transfer. Psychological Bulletin, 115, 4-18.
