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