Connecting With The Outside World: Psychosocially Supportive Aspects Of Operational Communication Between Isolated Crews In Space And Mission Control On The Ground, Dennis J. Frederiksen

Journal of Human Performance in Extreme Environments

Radio-based communication between crew members in space and mission control centers on the ground has the operational purpose of supporting the safe and effective execution of missions in space. Space-to-ground communication also, however, constitutes one of the relatively few interpersonal relationships astronauts have during missions and in addition to its operational purpose, this communication can support astronauts’ wellbeing. The purpose of this paper is to identify psychosocially supportive aspects of operational space-to-ground communication between astronauts in space and spacecraft communicators on the ground. Through qualitative analysis of authentic mission communication, this paper identifies two supportive aspects and develops a terminology …

Using Behavior Sequence Analysis To Study Teams During Long- Duration Isolation And Confinement, Andres Käosaar, Dr. Nathan Smith, Dr. David A. Keatley, Pranav Ambhorkar, Dr. Moritz Von Looz, Konstantinos Konstantinidis

Journal of Human Performance in Extreme Environments

With a renewed impetus and appetite for human space exploration, both government-funded agencies and private companies are focusing on longer and farther crewed missions into the solar system. Such space missions rely on highly interdependent teams living and working together in isolated, confined, and extreme (ICE) environments. Understanding the behavioral patterns of teams in ICE environments is, thus, paramount for the future success of such missions. Due to the complexity of studying ICE teams, several researchers have called for methodological innovations to advance knowledge in this area. In the current research, a proof-of-concept methodological approach is introduced that provides a …

The Combination Of Cooling Techniques In A Tropical Environment Improves Precision Performance In Young International Fencers, Aurélie Collado, Nicolas Robin, Stéphane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

The performance of intense exercise in a tropical climate is associated with limited exercise capacity due to thermal strain. This limitation is exacerbated in sports requiring full protective equipment. Research evidence suggests disturbances in cognitive function due to thermal discomfort and/or protective equipment (e.g., helmets), and thus sports that require skills in decision-making, fast reaction times, precision, and/or inhibition can be greatly affected. The objective of this study was to investigate the effects of countermeasures on the psychological and physiological responses in young international fencers wearing full protective equipment during an ecological fencing task. Nine young international fencers performed an …

Using An Approach-Avoidance Framework To Understand The Relationship Between Non-Lethal Weapons And Performance, Andrew J. Mojica, Christopher P. Bartak, Joseph N. Mitchell, Alan Ashworth

Journal of Human Performance in Extreme Environments

It is proposed that performance degradation from exposure to non-lethal technology is mediated by impulsive and reflective approachavoidance motivation. An approach-avoidance motivational framework was used to specify a four-stage information processing model that predicts performance degradation. The first stage is Evaluation: it processes physiological, sensory, perceptual, and cognitive information. The second stage is Comparison: it processes the content of the Evaluation into avoidance and approach motivational indices. The third stage is Probability: it processes information from previous stages into a probability of choosing to continue or abandon goal-directed behavior. Finally, the fourth stage is Performance: it processes performance accuracy on …

The study utilized commercial off-the-shelf cognitive and physiological monitoring techniques, along with subjective self-assessments and hematologic measurements to determine subject performance and changes across the …

Cognitive Offloading Strategies And Decrements In Learning: Lessons From Aviation And Aerospace Crises, D. Christopher Kayes, Jeewhan Yoon

Journal of Human Performance in Extreme Environments

Examples from aviation and aerospace illustrate the potential consequences that emerge when organizations replace learning from experience with technology, a process referred to as a cognitive offloading strategy (COS). Examples include the Air France Flight 447 crash involving an Airbus 330-203 and the Lion Air Flight 610 crash involving a Boeing 737 Max. From the perspective of human performance in extreme environments, COS represents an underexplored source of organizational vulnerability which presents a particular challenge for learning in organizations. Decrements in learning result from COS because COS creates gaps in procedural knowledge and deprives operators of opportunities to learn in …

A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal

Journal of Human Performance in Extreme Environments

In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

The results indicated (1) the spearfisher’s global organization during the spearfishing set, (2) the alternation of intentions during apnea and periods of stabilization, (3) harmony with the environment, and (4) the strategy of keeping pace with the fish. The article will discuss the specific competence development needed to manage the …

Coping During Conventional Submarine Missions: Evidence Of A Third Quarter Phenomenon?, Charles H. Van Wijk

Journal of Human Performance in Extreme Environments

The third quarter phenomenon refers to the decline in performance during the third quarter of missions in isolated, confined, and extreme environments, regardless of actual mission duration. This can be observed through changes in cognitive and interpersonal behavior, and an increase in reported negative experiences and undesirable mood states. This effect has been studied in polar and space missions, but there are no available reports on it during submarine missions. This study provides an additional analysis of previously published data that were collected during a conventional submarine patrol mission, to consider whether a stage-model of adaptation (in particular a third …

Impact Of Tropical Climate On Selective Attention And Affect, Guillaume R. Coudevylle, Maria Popa-Roch, Stéphane Sinnapah, Olivier Hue, Nicolas Robin

Journal of Human Performance in Extreme Environments

Heat has an impact on several aspects of human cognition but the effects of the tropical climate (i.e., hot and wet) have rarely been explored. The purpose of this study was to determine whether selective attention and affect are negatively impacted by the tropical climate. The study followed a within-participants design: participants responded to an affective scale (PANAS) and performed an attention task (d2 Test) in two experimental climate conditions (tropical vs. neutral) with a one-week interval between sessions. The results indicated that they had lower positive affect and selective attention in the tropical climate than in the neutral climate. …

Coping In Context: Dispositional And Situational Coping Of Navy Divers And Submariners, Charles H. Van Wijk

Journal of Human Performance in Extreme Environments

Specialists working in isolated, confined, and extreme environments may need to negotiate unique combinations of potentially stressful circumstances. This paper reports on three studies using the Brief COPE to examine some of the dispositional and situational coping strategies reported by navy divers and submariners.

The first study investigated whether individual members of these specialist groups would favor similar coping response styles, and found that divers (N = 174) and submariners (N = 195) generally report similar coping styles, with some context appropriate nuances in their reports. Further, they share much of their profiles with other high-demand occupational settings, …

Coping With The Subterranean Environment: A Thematic Content Analysis Of The Narratives Of Cave Explorers, Raymond R. Macneil, Jelena Brcic

Journal of Human Performance in Extreme Environments

In addition to various physical obstacles, the cave environment presents numerous psychological stressors that challenge human explorers. Sources of psychological stress include logistic issues (e.g., limitations to access, communication, and the availability of equipment), a lack of normal sensory stimuli, isolation and confinement, high performance demands, and social conflict associated with team coordination and requirements for cooperation. Thus, the success and safety of caving expeditions depend on the ability of explorers to effectively cope with highly stressful conditions and task demands. This was the first study to investigate coping within the context of caving and cave exploration. Utilizing scoring criteria …

These skills may be especially beneficial to athletes performing within natural and unstable risk sport environments. The current study assessed psychological skills among risk sport athletes (N = 232) and the impact of experience on the use of such skills. Risk sport athletes of varying degrees of experience completed a modified version of the Athletic Coping Skills Inventory (ACSI; Smith et al., 1995). Risk sport athletes exceeded the midpoint on all of the ACSI subscales, indicating psychological skills usage. Experienced …

Robust Resilience: Metaphor And Meaning In Assessing System Performance Ranges, Barrett S. Caldwell

Journal of Human Performance in Extreme Environments

The current emphasis on Resilience Week and the International Symposium on Resilient Cognitive Systems highlights a growing awareness of the importance of designing and operating engineering systems under a variety of environmental conditions and in response to dynamic events. Although there has been considerable confusion and drift in the use of the term, ‘‘resilience’’ as a concept dates back to dynamic systems study of complex ecological systems in the 1970s. This original definition relates clearly to quantitative metrics that link also to statistical process control techniques describing system performance as affected by external, ‘‘assignable’’ causes. This paper discusses important elements …

Robust Flight Deck Systems: Harnessing The Synergistic Power Of The Crew, Michael J. Stasio

Journal of Human Performance in Extreme Environments

Robust flight decks are possible in both normal and novel operations. Existing crew resource and error management programs can improve team-centered resilience with Oshry’s organization development (OD) principles. The need on the flight deck is to diminish the invisible behavioral gap between espoused theory and theory-in-use by balancing Oshry’s four basic elements that make up robust human systems—differentiation, homogenization, integration, and individuation. This low-cost OD vision is offered as a guide for organizations to tailor existing aircrew recurrent training modules. Assessment and diagnosis measures are recommended for continuous improvement, so this OD framework includes adaptive feedback interventions and soft-skills behavioral …
