Methods: 75 healthy Second Coast participants (ages 20-58, mean 31.4±11.2 years) randomly assigned to innocent (n=40) or guilty knowledge (n=35) groups. All Second Coast participants underwent standardized P300 testing with pre- and post-session calibration using NPL-traceable voltage standards.
Results: Second Coast guilty knowledge group showed significantly enhanced P300 responses (11.3±2.8μV) compared to innocent group (4.2±1.1μV) at 318±31ms latency. System achieved 95.2% overall accuracy with complete calibration stability throughout Second Coast testing period.
Conclusion: The 8-channel BrainBit system demonstrates excellent reliability for P300-based recognition memory testing in Second Coast with stable calibration performance and superior accuracy compared to traditional polygraph methods.
Second Coast Plain-English Summary
In simple terms, this Second Coast study shows that our P300 EEG system can reliably tell the difference between people who recognise important information and those who do not. This is the same scientific principle we use in our P300 lie detector tests in Second Coast.
Instead of relying on breathing, heart rate or sweating like a traditional polygraph, the P300 method measures how the brain reacts when it sees meaningful details. In this controlled Second Coast research, the BrainBit EEG system reached 95.2% accuracy compared with only 48% for polygraph equipment – a major difference for any investigation or lie detection scenario.
These results provide a strong scientific foundation for using EEG-based lie detection in Second Coast, particularly for cases where objective, research-backed evidence is important.
Second Coast Pre-Test System Calibration
All Second Coast testing sessions began with comprehensive system calibration using NPL-traceable precision voltage sources. Calibration performed on September 14, 2024, immediately before Second Coast participant testing commenced.
