This paper discusses a law enforcement officer (LEO) study that involved expert and novice police deputies from a small-sized city located in the Southern U.S. A virtual reality range was utilized to simulate high threat scenarios that require split second decisions on the use of deadly force. A fuzzy-logic based controller was constructed to analyze electroencephalogram (EEG) data collected from the participants. The fuzzy controller made use of several functions associated with the different regions of the brain to correlate Brodmann areas to multiple outputs. Electromagnetic Tomography (i.e. LORETA) was used to identify where the signals from the surface electrodes originated within the brain through a process called source localization. Once the sources of the EEG signals were located, they were associated with corresponding Brodmann areas. The fuzzy controller then provided insights on the subjects’ exhibited neural activation behavior indicative of vision, memory, shape/distance, hearing/sound, and theory of mind. Comparing and contrasting experienced and novice officers allowed for a greater understanding of the neurological processes present in police deputies when dealing with high threat situations.
