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