Conclusion: The 8-channel BrainBit system demonstrates excellent reliability for P300-based recognition memory testing in Llantwit Major with stable calibration performance and superior accuracy compared to traditional polygraph methods.
Llantwit Major Plain-English Summary
In simple terms, this Llantwit Major 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 Llantwit Major.
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 Llantwit Major 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 Llantwit Major, particularly for cases where objective, research-backed evidence is important.
