Perception

Test your powers of perception (waarnemingsvermogen)

   Look at the four dots in the middle of the picture for about 60 seconds.
   Look away at a white wall. You will see a circle of light. Blink a few
   times (met je ogen knipperen).
   What do you see?
   Question:   Do we see what is really there, or do we see what we
   expect (verwachten) to see?
   Think about it. Then you can start analysing your audience's response.

   Note You could also use this illusion as a fun note on which to end your
   presentation .In this case you should make a separate slide of the image.
