ABSTRACT Aggression is a human behaviour that has the potential to injure another person physically or emotionally. The aggression states of the human could be identify by using BPQ, however, some of the subjects are not honest while answering the survey. This effects the precision of the survey. In this studies, experimental works have been conducted to investigate the aggression states of the 10 subjects. The experimental protocol is proposed for inducing aggression while brain signals are recorded by using an electroencephalogram (EEG). The subjects are experience 4 states which are relaxing state before starting the experiment, aggression state when playing a video game in muted, aggression state when playing video game in a maximum volume, and post gaming state which is similar with the relaxing state but the time is after playing the video game. The subjects are asked to play a video game “Subway Surfers” while the brain signals are recorded. The original data may contain noises and a Butterworth filter is used to screen it. Then, the signals are cut into pieces called the window to extract significant features of the brain signals. The experimental protocols and signal processing techniques proposed can generate the aggression pattern.
