Abstract：Objective To analyze the interpersonal relationship interaction and psychological state changes in the long-term isolation and limited environment,and to explore the connection between the behavior and mental state of crew members.Methods Three Chinese crew members were confined at Lunar Palace 1 (a comprehensive base experiment for the life support of artificially closed ecological system),and completed 80 days of long-term isolation and isolation experiments.Ethological analyses based on video recordings of lunch each day were conducted using Observer XT to find the change patterns of behaviour.Meanwhile,subjects completed three validated and reliable psychological questionnaires,including weekly POMS (profile of mood state),biweekly WES(work environment scale),and GES(group environment scale).Results The duration of lunchtime increased significantly over time,and correlated positively with vigour.Positive facial expressions such as smiling and laughing were significantly negatively correlated with negative emotions assessed by the POMS and with many items in the GES and WES.Conclusion Lunch break durations and positive facial expressions seem to be particularly sensitive indicators of the emotional states of crew members,and may be useful to assess group environment and work environment.
