Objective: To investigate P300 event-related potential responses in recognition memory paradigms using the 8-channel BrainBit EEG system with Hill Street participants, comparing innocent participants versus those with concealed information, with complete calibration validation.
Methods: 75 healthy Hill Street participants (ages 20-58, mean 31.4±11.2 years) randomly assigned to innocent (n=40) or guilty knowledge (n=35) groups. All Hill Street participants underwent standardized P300 testing with pre- and post-session calibration using NPL-traceable voltage standards.
Results: Hill Street 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 Hill Street testing period.
Conclusion: The 8-channel BrainBit system demonstrates excellent reliability for P300-based recognition memory testing in Hill Street with stable calibration performance and superior accuracy compared to traditional polygraph methods.
Hill Street Plain-English Summary
In simple terms, this Hill Street 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 Hill Street.
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 Hill Street 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 Hill Street, particularly for cases where objective, research-backed evidence is important.
Hill Street Pre-Test System Calibration
All Hill Street testing sessions began with comprehensive system calibration using NPL-traceable precision voltage sources. Calibration performed on September 14, 2024, immediately before Hill Street participant testing commenced.
