I think it would be virtually impossible to set up an effective testing situation in TIA's class for this reason: the person being tested already knows that they are going to be stared at. Therefore they are already in an anticipatory state of mind...which will compromise the test. They're already anticipating being stared at...they're worrying about when it will or won't happen...and that confuses the mind, stresses it, and defeats the original purpose of seeing if a normally relaxed general awareness can pick up an unknown and unanticipated situation.

It's kind of like telling someone NOT to think about an elephant!

It automatically defeats its own premise.
