- Gary, Chuck, and all you PCT demonstrators -
-
- I have a different way of demonstrating PCT with a rubber band.
- Take two rubber bands (I prefer the big ones) and knot them
- together. Ask the participant to hold the ends of the rubber
- bands, one in each hand, facing you. With her hands outstretched,
- the knot will be directly in front of both of you. Then, point
- your finger at the knot and ask her to keep the knot directly in
- front of the tip of your finger. Begin moving your finger and she
- will automatically look at the relationship of the knot to the tip
- of your finger. Next, ask her to look at her left hand and watch
- it's actions, and try to achieve the same goal of keeping the knot
- at the tip of your finger. Obviously she can't. In fact, there is
- a strong internal urge to take a look at the knot-tip of finger
- relationship. Thus she will perceive the need for feedback and the
- inability to achieve goals by watching behaviors. I've found this
- is the best way to lay to rest the fact that we control our
- actions.
-
- An alternative is to get two people to participate. Begin with the
- two rubber bands knotted together. She holds the end of one rubber
- band, and he holds the end of the other rubber band, with the knot
- between them. Again, you point your finger with the tip being
- right at the knot. Then, move your finger around, and they have to
- keep the knot right at the tip of your finer. Now ask them to
- achieve the same goal by watching their actions and to concentrate
- on how they move their hands as they attempt to reach their goal.
- Or, tell them to watch each other's actions. Or, ask one of them
- to close their eyes and the task for the other becomes more
- difficult. Now move your finger about. Again, the internal desire
- on their part to look at the knot shows the need for feedback to
- achieve internal goals and the inability to control by
- concentrating on the actions. I find when you ask people to switch
- from watching the knot and its relationship to the tip of your
- finger to watching their hands move, it becomes so obvious how we
- control for input, not output. The nice thing about these
- demonstrations is that you don't need a chalk board, you can
- demonstrate this anywhere (with the exception of a phone booth),
- and you still maintain control over the disturbance.
-
- What do you think?
