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