Investigation of human trust by identifying stimulated brain regions using electroencephalogram

Abstract

Workplaces use complex systems for sophisticated tasks in the industry. Measuring the trust level of workers is vital to predicting their decisions on complex systems. This research investigates human trust through a word elicitation study by identifying stimulated brain regions on the specific brainwaves using an electroencephalogram (EEG) with power spectrum and coherence analysis. Results confirm that the frontal lobes in the alpha and beta waves have active connectivity in the trust and that the temporal lobes in the gamma waves have active connectivity in the mistrust. The findings can contribute to designing complex systems using neurological technology in workplaces.
