Analyzing fear using a single-sensor eeg device

Abstract

Single-sensor EEG hardware provides possibilities for researchers to measure fear in human beings. Previous research show that consumer-grade EEG devices can be used to measure different states of mind. However, as is often the case with similar research, post-hoc questionnaires are used to measure the emotional state. This paper will focus on the physiological and psychological state of an individual in fear, comparing continuous subjective feedback with EEG measurements. Data has been collected using a Myndplay Brainband and a rotary meter, while 30 subjects viewed soothing and scary films. The rotary meter proved useful for obtaining continuous feedback and, although more research is needed, differences in brainwaves for fearful and calm states are found for multiple frequency bands.
