【摘要】 The purpose of this study was to examine whether prolonged residence in the Antarctica had a significant impact on cognitive performance. Participants were members of the 24th and 25th Chinese Antarctic expedition teams. Cognitive performances were measured by tests designed to evaluate short-term recognition, memory searching and spatial cognition, and were measured at four intervals in January, March, April, and June 2010 respectively. With age controlled as a covariate, data were analyzed using repeated-measure ANOVA. The results showed that subjects’ short-term memory and recognition ability remained stable, while 82% of the team members improved their scores on the spatial cognitive ability test. These findings have importance for furthering our understanding of cognitive functioning in extreme environments.
