20.500.12556/RUL-187375 The impact of navigational alarms in ECDIS training assessing physiological signals The increasing reliance on ECDIS in maritime operations underscores the need to understand how navigational alarm affect human performance, yet evidence on their physiological impact during training remains limited. The study aimed to explore the effects of a stressful event on general autonomic arousal during navigational operations and how this relationship changes over the course of ECDIS training. A longitudinal design was employed with nine novice participants (N = 9), who completed repeated simulator sessions while physiological signals (EDA, ECG, PPG) were recorded and combined into a composite arousal index. The results showed that alarms significantly increased physiological arousal, with an initial rise followed by gradual attenuation across sessions. The findings indicate adaptation to repeated exposure and demonstrate that objective physiological measures capture dynamic training responses, supporting the need for their integration into simulator-based training to improve situational awareness, workload regulation, and maritime safety.
