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