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