“…In a previous experiment on psychological and physiological adaptation to acute hypoxia (Blanchet, et al, 1997;Noel-Jorand & Burnet, 1994a), where an altitude of 4,383 r n was reached by helicopter on the first day, a significant difference in performance was observed beween the experimental group and the control group on a test similar to that used in the present study. The subjects exhibited adaptation problems, including mood transformation with increased self-concern, lack of well-being, and frequently high scores on acute mountain sickness .…”

“…In addition to biological and physiological experiments (Noel-Jorand & Burnet, 1996), experimental psychological tests were administered to study the subjects' cognitive and motor performance as well as their changes in mood. stay at an altitude of 6,545 m on the top of Sajarna in Bolivia (Blanchet, et al, 1997;Nod-Jorand, et al, 1995;&chalet, Antezana, Bienvenu, Marchal, Soubervielle, Cauchy, LeTrong, Dkchaux, Kamici, Westerterp, Kayser, & Dubray, 1993). This work is the second part of a study on psychological and physiological adaptation to high altitude.…”

“…Hypoxia can be regarded as a stressor (Noel-Jorand, et al, 1995;Olive & Waterhouse, 1979;Ryn, 1979Ryn, , 1988Singh, Khama, Srivastava, Lal, Sujoy, Roy, & Subramanyan, 1969). To adapt to and cope with a variety of environmental constraints, including hypoxia, cold temperatures, disrupted sleep patterns, lack of privacy, and isolation (Banderet, 1977;Morrison, 1968;Shukitt & Banderet, 1988), subjects develop defenses that can be identified by analyzing their speech (Blanchet, et al, 1997;Noel-Jorand, et al, 1995). The "schizoid" and "paranoid" reaction states noted at high altitudes (Nelson, 1982) and at very high altitudes (Noel-Jorand, et al, 1995;Ryn, 1979Ryn, , 1988 as well as the "depressive" states observed in h~pobaric chambers (Katz, 1982) and in the field a t high altitudes (Blanchet, et al, 1997;Ryn, 1979Ryn, , 1988Nelson, 1982) may play an adaptive role in such cases.…”

“…A third part of the study was also carried out on physiological and psychological adaptation to chronic hypoxia during a 2-mo, stay at an altitude of over 4,000 m including a 3wk. stay at an altitude of 6,545 m on the top of Sajarna in Bolivia (Blanchet, et al, 1997;Nod-Jorand, et al, 1995;&chalet, Antezana, Bienvenu, Marchal, Soubervielle, Cauchy, LeTrong, Dkchaux, Kamici, Westerterp, Kayser, & Dubray, 1993).…”

The purpose of this study was to test an ascent program for ideal psychological adaptation to high altitudes. A psychological approach was used to test a model describing a gradual step-by-step ascent. Seven subjects spent nine days between 3,500 m and 4,400 m altitude, followed by eight days climbing 500 m each day from 3,500 m to 5,400 m. They performed a cognitive-motor task three times, once under normoxia, once under acute hypoxia, and once under chronic hypoxic conditions. Durations for these subjects were compared with those obtained by a control group tested under normoxia. Subjects' emotional state was assessed by analyzing their remarks during an interview conducted at 5,400 m and by calculating from the answers given to the three questions, a mood index for each subject. Analysis showed that the performances of both groups improved on the second and third administrations of the test. There was, however, no interaction between the group and the time of administration. Mood indexes indicated that the majority of the subjects had no trouble in adapting to the situation and few cognitive or emotional disturbances were observed. These findings may be attributed to the ascent being well designed and planned thereby preventing various possible forms of mountain sickness and other pathologies from developing in the subjects.

This article is aimed at introducing a French discourse analysis model, e.g. the ‘star model’, initiated by the LAA team led by Robert Vion in Aix-en-Provence, to English-speaking researchers. It will be argued that language activity is multi-dimensional and can be traced at various heterogeneous levels of speech productions belonging to macro as well as micro orders. Speakers achieve different varieties of positioning which result in negotiating an interactional space within a pre-given situation. The model is precisely designed to offer a unified and comprehensive view of such heterogeneous phenomena in constant interconnection. In this study, we also intend to illustrate our approach through the analysis of two different corpora. Speakers’ strategies under extreme conditions will be analysed; the various sequences used were taken from a special corpus which we were asked to study as part of a national research programme. In order to illustrate interactional space shifts, we will also use the transcript of a meeting which took place between a patient and a medical investigator in a hospital in Marseilles.
