· Control Questions

· Repeat questions

· Should not be exact repetitions of an earlier question.

· The investigator must rephrase or otherwise disguise the previous question.

· Repeat questions also need to be separated in time from the original question so the information cannot easily be remembered.

· Developed from recently confirmed or known information that is not likely to have changed

· If the answer to a control question is not given as expected, it may be an indicator of deceit.

Topical Examples:

· Last day of school, Vacation dates

· School events, Pop culture trivia
