You will need a cooperative volunteer for this demonstration.
Sit opposite your volunteer and note the direction of his or her gaze when

Watch the direction your subject gazes as she or he considers
the answers to your questions. Most people will look to the right
when thinking about language-related questions (the even-numbered questions)
