Whether wintering-over causes cognitive and sensory impairment and associated adaptation problems is still a subject of debate. Conflicting results reported in the literature may be due to the difference in the experimental tasks. Moreover, interpersonal variability can hide the effects.
Performance on cognitive and psychomotor tasks can be an indicator of adaptation problems.
Subjects were 10 scientists and 6 technicians (both clinically normal) who wintered-over for a year in the Antarctic. A subset of tasks of the AGARD battery of Standardized Tests for Research with Environmental Stressors (SB) was completed eight times during the isolation. To assess adaptation, the adaptability questionnaire (AQ) was completed by the physician before every performance test.
SB showed a sensitive period of adaptation at mid-winter and at the end of the isolation, but the performance in the different tasks did not deteriorate exactly at the same time. No systematic relationship between AQ notations and SB performances was noted. However, three subjects showed significant positive correlations: r > 0.8, p < 0.05 (i.e., low adaptation = low performance).
Some clinically normal individuals can experience adaptation problems, and SB tasks can be an indicator of these problems when comparisons are done at an individual level.
越冬是否会导致认知和感官损伤以及相关的适应问题仍是一个存在争议的话题。文献中报道的相互矛盾的结果可能是由于实验任务的差异。此外,个体差异可能会掩盖这些影响。
认知和心理运动任务的表现可以作为适应问题的一个指标。
研究对象为10名科学家和6名技术人员(均无临床异常),他们在南极越冬一年。在隔离期间,对《环境应激源研究标准化测试AGARD量表》(SB)中的一部分任务进行了8次测试。为了评估适应性,医生在每次性能测试前通过适应性问卷(AQ)进行评估。
SB显示在冬季中期和隔离结束时有一个敏感的适应期,但不同任务的表现并非恰好在同一时间变差。未发现AQ评分与SB表现之间存在系统关系。然而,有三名受试者显示出显著的正相关:r > 0.8,p < 0.05(即适应能力低 = 表现差)。
一些临床正常的个体可能会出现适应问题,当在个体层面进行比较时,SB任务可以作为这些问题的一个指标。
