Thanks
for your participation. We are
interested in how people look at pictures that they will later have to
recognize. During the experiment we
will monitor your eye position while you view photographs. After you have viewed all of the photographs
you will be given a test to determine how well you encoded the information in
the photos.
Tracking
eye movements can be a tricky business.
The eye tracker fails to produce good data if the subject moves his/her
head during the experiment. To minimize
this error we have a chin rest that will help stabilize your head. In addition, before the task begins we need
to calibrate the eye-tracker for your eye.
During this calibration and during the subsequent test it is important
that you hold you head as still as possible.
To this end please avoid moving, and do not talk during the calibration
and testing.
Once
the experimenter has the eye tracker calibrated, the experiment will
begin. It will have 4 parts. At the beginning and end of the experiment a
series of 4 red crosses will appear on the screen. These crosses allow us to check that the calibration is still
accurate. Please look directly at these
crosses when they appear. In the middle
portion of the experiment you will see the photographs. Thanks again for your participation.
