Abstract
This study carried out the long-time voyage simulation experiment in the independently developed experimental cabin to explore the cognitive behavior and subjective evaluation index of seafarer's alertness during the simulated long-time voyage, and test the effectiveness of the cognitive behavior indicators for seafarer's alertness during the simulated long-time voyage. The results show that during the long voyage, the score of KSS was sensitive about seafarers’ subjective alertness decline from duty during the long voyage, the mean response time, standard deviation of response time and lapse of PVT task was sensitive about seafarers’ cognitive alertness decline from duty during the long voyage. The predictive effect of cognitive behavior index of alertness on the subjective alertness of long-time seafarers is better in the early voyage and worse in the middle voyage, which may be related to the rhythm disorder of seafarers in the middle and late voyage. The predictive effect after duty is better than before duty. Therefore, PVT task is more suitable for early vigilance assessment of long-time voyage seafarers and has more vigilance prediction on seafarer’s alert after duty. When the seafarer’s rhythm is disordered, PVT's prediction of seafarer’s vigilance will be greatly inconsistent with the seafarer’s subjective perception of alert.
