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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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).
