Steven,
Two of the most robust and fascinating demonstrations that I use in S & P
are the McCullough Effect and a Change Blindness demonstration. The ME
demo can be easily done in any classroom. I usually have a student
alternate the red & green training slides in a 35mm projector. While the
student alternates the slides at about a four sec ISI I deliver a little
lecture on the history of the effect. After about 10 minutes I switch to
the test pattern and wait for the OOHs & AHHs. Then we discuss the
various theories of how this might work. BTW there is a good paper that
just came out whic provides fMRI data (Humphrey, K. James, T. Gati, J.
Menon, R. & Goodale, M. (1999) Perception of the McCullough effect
correlates with activity in extrastriate cortex: A functional magnetic
resonance imaging study. Psychological Science.10(5). 444-448.). A
full-text version of this paper is available at the APS web
site http://www.psychologicalscience.org/.
For the change blindness demo (Simons,-Daniel-J.; Levin,-Daniel-T.
Failure to detect changes to people during a real-world interaction.
Psychonomic-Bulletin-and-Review. 1998 Dec; Vol 5(4): 644-649) I have 10
.jpeg images that I downloaded from the net and then radically altered
using Paintshop Pro. I tell students that they will be exposed to the
first image for a considerable length of time 20-30 sec. and then the
picture will be replaced with an altered image. Students are instructed
that at least one thing (and sometimes many things) will be changed
between image one and image two. I challenge the students to identify
all of the changes. To date, no one has come close. The images can be
radically different and yet some students will see no change. For
example, In one of the image sets a closeup portrait of a young girl changes
from having a vivid red scarf to a dull blue scarf and yet people miss
the change.
Hope these help -Don.
