Perception Deception
Yesterday I was doing a pretty good job of balancing on the inverted BOSU. This feat requires a lot of concentration and focus as the brain keeps sending messages to the legs, ankles, and feet, all of which keep wiggling to keep you upright. Then Patti put a free weight in each of my hands and told me to do bicep curls. After I had done two sets of 10 bicep curls, I handed the weights back to her and jumped off the BOSU.
"I bet it hardly felt like you were doing bicep curls," Patti said.
WHOA! She was right. My brain was working so hard on maintaining my balance that it didn't have time to focus on what my arms were doing. (Actually, it's probably more accurate to say that, when I started lifting the weights, my brain also had to take that movement into account and work even harder at keeping me from falling off the BOSU.) At any rate, my brain wasn't concerned with registering the heaviness of the weights because it just had too much else on its mind.
Do you remember the picture that could be either a vase or two faces in profile from an earlier post? Once you could recognize both ways to see the image, you could still only see one image or the other at any given moment. Even though our brains are amazingly quick and slick calculating apparatuses, they are limited in the amount of input they can process at once.
My experience of doing bicep curls on the BOSU is another example of this. When too many different stimuli are bombarding us all at once, our brain will pick out the most important ones and selectively ignore the rest. Since balance is crucial to a creature that walks upright, my brain put most of its effort there and paid little mind to those 8-pound weights in my hands. Those same weights would have felt a lot heavier if I had been simply standing on the floor while doing those bicep curls.
Thanks for this informative observation, Patti. (And no, this doesn't mean that we should increase my weights.)
