Terms related to Tests
- Diagnostic Test: A test protocol used when there is a known incident or allegation. This is the primary protocol used for investigations.
- Screening Test: A test protocol used to question about generalized topics where there is no known incident or allegation. This is the primary protocol used for pre-employment screening.
- Relevant Topic (R1, R2, R3): A topic related to an act or target behavior of primary concern. It is the primary area of focus for the test.
- Comparison Topic (CQ): A low base rate (low probability) act or target behavior. It is used to measure and record a baseline reaction of the examinee when there is a very high likelihood the examinee is truthful about the topic.
- MCT or Multi-issue Comparison Test: A protocol used to test 2 or 3 relevant topics and 1 comparison topic. MCT is often used for screening tests.
- AMCT or Audio MCT: A variation of the MCT protocol for poor readers. No text is presented to the examinee on the screen and the entire test is presented aurally.
- HMCT or Hybrid MCT: A variation of the MCT protocol that combines polygraph and EyeDetect testing techniques.
- Directed Lie (DL): Test questions for which the examinee is instructed to lie. DL questions are used for comparison to the relevant issue.
- DLC2 or Directed Lie Comparison Test 2: A second generation DLC test with 1 relevant topic and uses directed lie questions used for comparison. DLC3 is often used for single-issue (diagnostic) tests.
- DLC3 or Directed Lie Comparison Test 3: A third generation DLC test with 1 relevant topic and uses directed lie questions used for comparison. DLC3 is often used for single-issue (diagnostic) tests.
- HDLC or Hybrid DLC: A variation of the DLC protocol that combines polygraph and EyeDetect testing techniques. It supports 1 relevant topic and uses directed lie questions for comparison.
- RCT or Relevant Comparison Test: First EyeDetect testing protocol with 1 relevant topic and 1 comparison topic. It was later updated to the MCT, but is still often used when directed lie is not ideal.
- V3R or VerifEye 3R Test : Based on the Audio MCT protocol, this test allows 1 relevant topic and 2 comparison topics. V3R can be used for diagnostic tests.
- V4R or VerifEye 4R Test : Based on the Audio MCT protocol, this test allows 3 relevant topics and 1 comparison topic. V4R can be used for screening tests.
- BRG or Base Rate of Guilt: The number of people in a testing group found guilty of the incident or target behavior. In field cases, the true BRG is never truly known, it is always estimated.
Test Guidelines for Relevant Topic Questions
When determining what types of questions can be asked in a lie detection test, please consider the following guidelines:
- Focus on specific actions or behaviors
- Focus on examinee’s experience/actions – not others
- Be clear and concise – not subjective
- Use time frames to narrow scope
- Consider if pretest admission have been made
- Don’t ask about intent, desires or emotions
- Don’t use accusatory or assuming language
- Don’t use legal, emotionally charged or judgmental terms
- Focus on behaviors that have an impactful consequence
- Avoid “Truth Confirmation” topics like testing victims or honesty on full disclosure documents
- When using multi-issue format, make sure all test topics are distinct and different – not crossover
