Braintree Study Abstract
Objective: To investigate P300 event-related potential responses in recognition memory paradigms using the 8-channel BrainBit EEG system with Braintree participants, comparing innocent participants versus those with concealed information, with complete calibration validation.
Methods: 75 healthy Braintree participants (ages 20-58, mean 31.4±11.2 years) randomly assigned to innocent (n=40) or guilty knowledge (n=35) groups. All Braintree participants underwent standardized P300 testing with pre- and post-session calibration using NPL-traceable voltage standards.
Results: Braintree 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 Braintree testing period.
Conclusion: The 8-channel BrainBit system demonstrates excellent reliability for P300-based recognition memory testing in Braintree with stable calibration performance and superior accuracy compared to traditional polygraph methods.
Braintree Plain-English Summary
In simple terms, this Braintree 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 Braintree.
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 Braintree 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 Braintree, particularly for cases where objective, research-backed evidence is important.
Braintree Pre-Test System Calibration
All Braintree testing sessions began with comprehensive system calibration using NPL-traceable precision voltage sources. Calibration performed on September 14, 2024, immediately before Braintree participant testing commenced.
