Planning to take a lie detector or EyeDetect test? This guide explains exactly how to prepare, what happens during the test, and how to make sure your results are accurate and reliable—based on decades of real-world experience at Australian Polygraph Services.
✅ Step-by-Step Guide: How to Prepare for a Lie Detector Test
Whether you’re taking the test for a relationship issue, a workplace investigation, or to prove your innocence—preparation is key. Here’s how to get ready:
1. Get Quality Sleep the Night Before
Avoid arriving fatigued. A rested brain improves focus and helps the test detect truthful responses clearly.
2. Avoid Alcohol and Recreational Drugs
For at least 24 hours prior to testing. Prescription medications are usually fine—just disclose them to the examiner in your pre-test interview.
3. Eat a Light Meal Before the Test
An empty or overly full stomach can cause discomfort and physiological changes. Eat normally, but not heavily, 1–2 hours before.
4. Dress in Comfortable Clothing
You’ll be seated during the test, so wear something relaxed and non-restrictive.
5. Verify the Examiner’s Qualifications
Ask the examiner to show proof of certification from recognised bodies like the American Polygraph Association. There is no professionally recognised polygraph Association in Australia. A qualified examiner is critical for an accurate and ethical result.
6. Avoid Trying to “Beat” the Test
There’s no reliable way to cheat a properly conducted polygraph or EyeDetect test. Trying to manipulate the process often leads to inconclusive or failed results.
👨⚕️ What Happens During a Polygraph or EyeDetect Test?
Step 1: Pre-Test Interview with the Examiner
You’ll meet with a certified examiner (such as Steve van Aperen) who will:
- Explain the entire process
- Review your medical history
- Clarify the issue being tested (e.g., infidelity, theft)
- Walk you through all the test questions in advance
You’ll also sign a consent form and a written declaration summarising your position.
Step 2: The Test Procedure Explained
🔎 Polygraph Test (Lie Detector)
- Conducted with sensors that measure heart rate, breathing, blood pressure, and sweat response.
- You’ll answer a series of yes/no questions across 3–4 testing rounds.
- Total duration: 90–120 minutes.
👁️ EyeDetect Test
- Uses an infrared eye-tracker and AI algorithms to detect signs of deception.
- You sit in front of a computer and answer true/false questions.
- Measures pupil size, blink rate, reading behaviour, and eye fixations.
- Non-invasive and fast. Duration: 45–60 minutes.
Step 3: After the Test: Results and Reporting
- Your test data is analysed using scientific scoring algorithms.
- Results are typically available within 10 minutes after testing.
- A full written report is issued and can be used for personal, legal, or employment matters.
- A verbal summary may be provided on the day (depending on the context).
🧠 Frequently Asked Questions
