Psychosocial issues in isolated and confined extreme environments.

PALINKAS, L.A., and P. SUEDFELD. Psychosocial Issues in Isolated and Confined Extreme Environments. NEUROSCI BIOBEHAV REV (1) XXX-XXX, 2020. Psychosocial elements of behavior and performance will significantly impact the outcomes of long duration missions in space, ranging from individual and team decrements to positive benefits associated with successful adaptation. This paper reviews our current understanding of the individual, interpersonal and organizational issues related to living and working in isolated and confined extreme (ICE) environments. Individual issues include changes in emotions and cognitive performance; seasonal syndromes linked to changes in the physical environment; and positive effects of adapting to ICE environments. Interpersonal issues include processes of crew cohesion, tension and conflict; interpersonal relations and social support; the impact of group diversity and leadership styles on small group dynamics; and crew-mission control interactions. Organizational issues include the influence of organizational culture and mission duration on individual and group performance, crew autonomy, and managerial requirements for long duration missions. Improved screening and selection, leadership, coping and interpersonal skills training, and organizational change are key elements to optimizing adjustment to the environment and preventing decrements during and after long duration missions.

The Creative Brain Under Stress: Considerations for Performance in Extreme Environments.

Over the last 2 decades, we have begun to gain traction on the neural systems that support creative cognition. Specifically, a converging body of evidence from various domains has demonstrated that creativity arises from the interaction of two large-scale systems in the brain: Whereas the default network (DN) is involved in internally-oriented generation of novel concepts, the executive control network (ECN) exerts top-down control over that generative process to select task-appropriate output. In addition, the salience network (SN) regulates switching between those networks in the course of creative cognition. In contrast, we know much less about the workings of these large-scale systems in support of creativity under extreme conditions, although that is beginning to change. Specifically, there is growing evidence from systems neuroscience to demonstrate that the functioning and connectivity of DN, ECN, and SN are influenced by stress - findings that can be used to improve our understanding of the behavioral effects of stress on creativity. Toward that end, we review findings from the neuroscience of creativity, behavioral research on the impact of stress on creativity, and the systems-level view of the brain under stress to suggest ways in which creativity might be affected under extreme conditions. Although our focus is largely on acute stress, we also touch on the possible impact of chronic stress on creative cognition.

The data on psychological adaptation during polar winter-overs in Sub-Antarctic and Antarctic stations.

The data presented in this article relate to the research article entitled "assessing psychological adaptation during polar winter-overs: The isolated and confined environments questionnaire (ICE-Q)" [1]. These data were acquired in order to develop a standardized instrument - the ICE-Q - designed to assess psychological adaptation within isolated, confined, and extreme environments. A total of 140 winterers from several sub-Antarctic (Amsterdam, Crozet, Kerguelen) and Antarctic (Concordia, Terre Adélie) stations voluntarily participated. Data were collected by multiple self-report questionnaires including a wide variety of well-known and validated questionnaires to record the winterers' responses to polar stations. Data were gathered across two or three winter seasons within each of the 5 polar stations to ensure sufficiently large sample. From four to seven measurement time along a one-year period were proposed to the participants, resulting in 479 momentary assessments. Results of exploratory factor analyses, confirmatory factor analyses, exploratory structural equation modelling, reliability analyses, and test-retest provided strong evidence for the construct validity of the ICE-Q (19-item 4-factor questionnaire). The four factors were social, emotional, occupational and physical. Future studies would examine the dynamic of psychological adaptation in isolated, confined and/or extreme environments during polar missions.

Pathogens and politics: further evidence that parasite prevalence predicts authoritarianism.

According to a "parasite stress" hypothesis, authoritarian governments are more likely to emerge in regions characterized by a high prevalence of disease-causing pathogens. Recent cross-national evidence is consistent with this hypothesis, but there are inferential limitations associated with that evidence. We report two studies that address some of these limitations, and provide further tests of the hypothesis. Study 1 revealed that parasite prevalence strongly predicted cross-national differences on measures assessing individuals' authoritarian personalities, and this effect statistically mediated the relationship between parasite prevalence and authoritarian governance. The mediation result is inconsistent with an alternative explanation for previous findings. To address further limitations associated with cross-national comparisons, Study 2 tested the parasite stress hypothesis on a sample of traditional small-scale societies (the Standard Cross-Cultural Sample). Results revealed that parasite prevalence predicted measures of authoritarian governance, and did so even when statistically controlling for other threats to human welfare. (One additional threat-famine-also uniquely predicted authoritarianism.) Together, these results further substantiate the parasite stress hypothesis of authoritarianism, and suggest that societal differences in authoritarian governance result, in part, from cultural differences in individuals' authoritarian personalities.

Finding the team for Mars: a psychological and human factors analysis of a Mars Desert Research Station crew.

A two-week mission in March and April of 2011 sent six team members to the Mars Desert Research Station (MDRS). MDRS, a research facility in the high Utah desert, provides an analogue for the harsh and unusual working conditions that will be faced by men and women who one day explore Mars. During the mission a selection of quantitative and qualitative psychological tests were administered to the international, multidisciplinary team. A selection of the results are presented along with discussion.

The cognitive processing of politics and politicians: archival studies of conceptual and integrative complexity.

This article reviews over 30 years of research on the role of integrative complexity (IC) in politics. IC is a measure of the cognitive structure underlying information processing and decision making in a specific situation and time of interest to the researcher or policymaker. As such, it is a state counterpart of conceptual complexity, the trait (transsituationally and transtemporally stable) component of cognitive structure. In the beginning (the first article using the measure was published in 1976), most of the studies were by the author or his students (or both), notably Philip Tetlock; more recently, IC has attracted the attention of a growing number of political and social psychologists. The article traces the theoretical development of IC; describes how the variable is scored in archival or contemporary materials (speeches, interviews, memoirs, etc.); discusses possible influences on IC, such as stress, ideology, and official role; and presents findings on how measures of IC can be used to forecast political decisions (e.g., deciding between war and peace). Research on the role of IC in individual success and failure in military and political leaders is also described.

Changes in the hierarchy of value references associated with flying in space.

One hundred twenty-five astronaut autobiographies, interviews, and oral histories were content analyzed and scored for references to values (Schwartz, 1992). The current study extended methods tested in 2 pilot studies of space veterans from many nations, of both sexes, and with different experiences within the history of human spaceflight. Value references reflected a high degree of concern with individualism, with Achievement, Enjoyment, and Self-direction ranked highest. There were relatively few value differences across demographic categories, demonstrating the impact of the spaceflight experience. After returning, the astronauts showed increased concern with Universalism, Spirituality, and Power (social recognition), a broadened set of references to values oriented toward the collective good.

Psychological effects of polar expeditions.

Polar expeditions include treks and stays at summer camps or year-round research stations. People on such expeditions generally undergo psychological changes resulting from exposure to long periods of isolation and confinement, and the extreme physical environment. Symptoms include disturbed sleep, impaired cognitive ability, negative affect, and interpersonal tension and conflict. Seasonal occurrence of these symptoms suggests the existence of three overlapping syndromes: the winter-over syndrome, the polar T3 syndrome, and subsyndromal seasonal affective disorder. About 5% of people on expeditions meet DSM-IV or ICD criteria for psychiatric disorders. However, they also experience positive or so-called salutogenic outcomes resulting from successfully coping with stress and enhanced self-sufficiency, improved health, and personal growth. Prevention of pathogenic psychological outcomes is best accomplished by psychological and psychiatric screening procedures to select out unsuitable candidates, and by providing access to psychological support, including telephone counselling. Promotion of salutogenic experiences is best accomplished by screening for suitable personality traits, and training participants in individual coping strategies, group interaction, and team leadership.

Psychological selection of Antarctic personnel: the "SOAP" instrument.

INTRODUCTION: The potential advantage of including a psychological test battery in the selection process for service in the Antarctic was examined in 348 applicants for employment in Antarctica with the British Antarctic Survey (BAS). METHODS: Applicants were screened with the Selection of Antarctic Personnel battery (SOAP) consisting of nine well-known psychological instruments. The SOAP scores were not revealed to the BAS selection panel members, who based the selection on operational criteria, interview, and a general medical examination. The SOAP scores of those selected (n = 177) were further compared with station commanders' reports of winter adaptation (n = 140), and subjective health complaints (SHC) (n = 86). RESULTS: There were no significant agreements between SOAP scores (n = 348) and those actually selected by the BAS panel (121 accepted, 227 not accepted) (Cohen's Kappas for inter-rater agreement < 0.20). Participants characterized as exceptionally well adapted by the station commanders had higher scores on Openness on the NEO-FFI (the "Big Five" personality inventory) [Odds Ratio (OR) = 5.2], and higher levels of Emotion-Focused Coping (OR = 2.7) and fewer SHC (OR = 0.3). Participants rated by station commanders as "poor" had higher levels of Defensive Hostility (OR = 4.2), and lower levels of Emotion-Focused Coping (OR = 0.3). Women had higher rates of success in service than men, but were less likely to be selected. DISCUSSION AND CONCLUSION: Adding a psychological test battery would improve the odds of selecting good performers, and reduce the odds of selecting poor performers.

Invulnerability, coping, salutogenesis, integration: four phases of space psychology.

The relationship between NASA and the psychological research community has progressed through a number of phases during the past four decades. This paper summarizes how the relationship has developed as data have accumulated and space missions and crews have changed. In the beginning, most NASA astronauts and staff considered possible psychological problems during space missions to be a non-issue. It was assumed that people with "the right stuff" would not experience any such problems. A more realistic recognition of stress and its consequences has led to a concern with prevention and countermeasures, a concern that has come to dominate NASA's involvement with psychology. Very recently, space psychologists have started to import the concepts of positive psychology, and consider the benefits of participation in the space program, including the self-enhancing aspects of stressful experiences (salutogenesis). Both the agency and psychologists now need to broaden their thinking and their research to cover the gamut of empirical data and theoretical concepts. These include human strengths as well as vulnerabilities, both negative and positive impacts of spaceflight, long- as well as short-term effects, and the reactions not only of the astronauts themselves but also of ground personnel and the families of both groups.

The Holocaust as a context for telling life stories.

Using a narrative approach, this study explores the role of the Holocaust in the life stories of Survivors, contrasted with two comparison groups (one Jewish and one non-Jewish) whose direct experiences did not include surviving the Holocaust. Using the technique of the life line and measures such as number and type of life events identified, as well as the events marking the beginning and ending of the life story, several differences were found between the three groups. Survivors identified an average of 10 life events, fewer than the non-Jewish comparison group (18) but more than the Jewish comparison group (7). Most of these events were positive, although less so for the Jewish comparison group, with very few future events identified by any of the groups. The War marked the beginning of the life story for most of the survivors and their stories ended at an earlier age than did the stories of the comparison groups. Further, WWII events predominated in the stories of the survivors, as did family births and relationship events (comparably seen in the stories of the Jewish comparisons). In contrast, the comparison groups, and particularly the non-Jewish group, identified greater numbers of career, education, illness, and family death events. It is proposed that the pronounced effect of the Holocaust in the life stories of survivors (and to a lesser, though still evident, degree of the Jewish comparisons) serves as an anchoring and contextual influence on the nature and quality of life stories told. That is, the Holocaust sets the standard for what events merit mention and further determines the nature of the events reported and their distribution.

Erikson's "components of a healthy personality" among Holocaust survivors immediately and 40 years after the war.

This study assessed the degree to which Holocaust survivors have dealt successfully with the eight psychosocial crises thought by Erikson (1959) to mark important stages in life-span development. In Study 1, 50 autobiographical interviews of survivors videotaped 30-50 years after the war were subjected to thematic content analysis. Relevant passages were coded as representing either a favorable or an unfavorable outcome as defined by Erikson. Survivors described significantly more favorable than unfavorable outcomes for seven of the crises; the exception was Trust vs. Mistrust. In Study 2, audiotaped Holocaust survivor interviews conducted in 1946 were scored in the same way and compared with the results of Study 1. There were several significant differences as well as similarities between the two data sets, the later interviews mostly showing changes in the positive direction.

Child Holocaust survivors as parents: a transgenerational perspective.

Children of Holocaust survivors frequently point out problems associated with having been raised by survivor parents. However, large-scale studies demonstrate that both Holocaust survivors and their children function within the normal range. This study addresses relationship issues between the younger survivors and their children. It does not compare them with nonsurvivor families, who may exhibit similar patterns. We found wide gaps between how child survivor parents and their children viewed parental expectations and behaviors. These discrepancies are described as 4 paradoxes.

The impact of outer space on inner space.

Thematic content analysis for 11 seminal values was applied to the published memoirs of 4 early U.S. astronauts (John Glenn, Gordon Cooper, "Buzz" Aldrin, and Michael Collins). Premission values did not show the expected conventional pattern; some regularities were observed across the pre-, during-, and postflight profiles. Aldrin's post-NASA adjustment problems were possibly related to his highly (and uniquely) skewed focus on Achievement to the exclusion of other values. Because of the small and unrepresentative sample of both subjects and measures, this paper is best considered an illustration of the potential usefulness of thematic content analysis in studying the history of human spaceflight and the understanding of astronauts' lives.
