What is The effects of motivation and noise on situation awareness: A study based on SAGAT and EEG about?

The current research results have differences in the correlation between situation awareness (SA) and physiological data, and there is a lack of systematic research on the influence of motivation and noise on SA. This study investigated the correlation between SA and electroencephalogram (EEG) signals under the effects of motivation and noise. The independent variables were motivation (two levels: positive and negative) and noise (three levels: no noise, natural noise, and speech noise). And the dependent variable were the levels of SA in perception, comprehension and projection. Participants were required to observe traffic videos of three types of noise under two types of motivation and complete the Situation Awareness Global Assessment Technique (SAGAT) questionnaire after each video. We recorded the participants' EEG signals and calculated the average relative power of the delta, theta, alpha, and beta bands of each brain region. The results showed that the levels of perception and projection under negative motivation were higher than those under positive motivation. The level of perception was negatively correlated with the delta band power in the central lobe and theta power
