Abstract:
Objective:To study the changes of the crew’s cognitive function and performance during long oceangoing voyages.Methods:The cognitive function and performance of the crew members of the " Mission Harmony 2018" were measured by the attention distribution instrument (EP708A), finger dexterity tester (EP109), and trail making test A and B at 1 month and 6 months after the Mission began, and the data were compared.Results:Comparing the data at 6 month after the Mission began with those at 1 month after the Mission began, the correct responses of the crew to the low-, middle-, and high-pitch sound were significantly increased ( P<0.01); the reaction time to middle-pitch sound and light was significantly reduced ( P<0.05); the wrong responses to low-pitch sound were significantly reduced ( P<0.01); the completion time of trail marking test A was significantly reduced ( P<0.05), while that of test B was significantly increased ( P<0.05); the time to finish finger dexterity task was significantly reduced ( P<0.01). Conclusion:The crew members had better cognitive function and performance in the late leg of the voyage than those in the early leg of the voyage.
