Chewing Gum experiment

Was (re)looking over the baby-sign language-babbling experiments by the group of Laura Ann Petitto at Dartmouth and I thought of a kooky expeirment to show that speaking recruits the left hemisphere in adults.

• Give a bunch of people chewing gum, to chew
• Get them to do some kind of task (like the Map Task?) which involves verbal and non-verbal communications.
• Measure where the gum is during bouts of (1) verbal communication (2) non-verbal communication

The hypothesis predicts that during the verbal communication phase, the gum will be on the left side of the mouth... Simple. Direct. Easy to do. If you do do the experiment, I want authorship or I sue your @$$ ps: The exact route from the babbling babies to the C.G. Experiment is tortuous and I cannot recreate it. Here is a very cute baby video from supplementary material for one of these experiments.
