Preliminary Study on Neurological Measure of Human Trust in Autonomous Systems

摘要

Autonomous systems, organizations, and interpersonal interactions are rapidly becoming more complex in a contemporary society. Trust plays a crucial role in assisting the cognitive complexity and increased uncertainty in complex systems. The previous studies focus on brain regions using fMRI and efMRI, which engage with stimuli related to trust and mistrust. This research measures and analyzes brainwaves in situations involving trust and mistrust to understand the cognitive process by using an electroencephalogram (EEG). For recording brainwaves on trust and mistrust situation, this experiment uses a word elicitation study from a previous research containing words related to trust and mistrust that were ranked by survey participants. Participants' brainwaves are recorded in real time as they are watching the selected words which evoke trust and mistrust situation. The 10-20 system of electrode placement is used for recording brainwaves and power spectrum analysis is used for brainwaves analysis. The result is that specific brainwaves can be affected by a trust or mistrust situation. A goal of this research is to identify brainwaves in trust and mistrust situations and to analyze a relationship between the brainwaves and human behaviors.
