February 20: Seeing something you have never seen before. Take a flashlight into a
the flashlight, and hold it above and to the right of your head, aiming the beam toward
your eye. Move the light around in small, concentric circles. If you are patient, you will
likely see something that you have been looking at all of your life without seeing it: the
blood vessels that run across the retina in the back of your eye. Draw, describe, and
explain what you see.

March 14: Weber fraction experiment.
Collect three U.S. quarters (75 cents total value), two identical paper envelopes, a
pair of fairly new shoes (so that they are equally worn), and a willing research
participant, like a roommate.
Place one of the quarters in on envelope, and two of the quarters in the other
envelope. Blindfold the research participant, and then place one envelope on the
upturned palm of one hand, and the other envelope on the other hand. Ask the person to
tell you which envelope is heavier. Record the response. Remove the envelopes and
repeat the test for a total of 10 trials. Be sure to randomly mix up which hand gets the
envelope with two quarters in it.

Then, place one of the envelopes in one of the shoes, and the other envelope in the
other shoe. Conduct the same study, for ten trials, this time placing one shoe on each
hand. Compare the overall percentage of correct identifications for the envelope
condition with that for the shoe condition. Are the judgments more accurate for one
condition?

Write a one-page report of the results of your study, including the data record
(format below) and the percentage analysis. Evaluate whether your results are in accord
with the Weber fraction, which says that judgments of a constant-sized difference (in this
case, the difference of one quarter in weight) is more difficult when the total weight being
compared is greater (shoes vs. envelopes). Show in your discussion that you understand
the theory of the Weber fraction.
