Other than Questions! are they control questions?

[sam]

Just recently I had a  pre employment polygraph that two of the questions on it were Other than questions. I am wondering if this style of question was a control question? And how many control questions are usually asked on a test.

Questions such as, "Other than what you've told me, have you ever stolen anything?" are control questions.  The examiner assumes you will lie when you answer them.  Your physiological responses when answering those questions will then be compared to your responses when answering relevant questions.

[George W. Maschke]

While following pre-test admissions, "control" questions often end up being prefaced with "Other than what you've told me..." the mere fact that a question begins with "Other than what you told me..." doesn't necessarily make it a "control" question.

For example, many examinees will make admissions when asked about the use of illegal drugs. After such admissions have been made, they may be asked during the in-test phase, "Other than what you've told me, did you ever use an illegal drug?" But this is a relevant question, not a "control."
