The purpose of this research is to explore the relationships between self-image and personality characteristics with cognitive impairment in an isolated group during wintering. Cognitive performance is measured with the Stres Battery (SB), self-image by Abraham’s Matrix of Intra- and Inter-Processes in Groups (MIPG), and interpersonal characteristics by the usual personality inventories. Results show that good cognitive performances are related to discordances between the real self and the ideal self and that bad performances are related to harmony between these two images. Moreover, the best cognitive performers have low scores in extroversion and assertiveness. The results are discussed in terms of specific adaptive reactions to wintering.
