Hey All,
At the beginning of this thread, I wrote a reply and think I made a
mistake in sending it, so I thought I try again:
Most of the physiological measurements are cheap and generally easy.
Did them years and years ago. Stable electrode contacts and and
stable contacts generally are the biggest problem. It's most human
engineering.
Since lie detectors don't work as such, I wouldn't continue to push
the myth.
The APA sponsored Psychology show had a good GSR in it that involved
a race between the tortoise and hare. The hare's speed was
dynamically controlled by it's progress towards the finish…and the
tortoise just plodded along. I thought that was a lot of fun.
Thinking about it more: The term "polygraph" refers to multiple
traces and strictly it's a series of physiological measurements. From
my experience, there is gross confusion about the use of polygraphs,
lie detectors, and other widgets exists, it becomes a very hard topic
to adequately present without instigating further confusion. It's
part of their "charm," and curse.
