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 …

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 …

Walking On ‘‘Mars’’: Gendered Group Processes In Space Analog Missions, Inga Popovaite, Alison J. Bianchi

Journal of Human Performance in Extreme Environments

Most research on mixed-gender teams in space analog environments focuses on individual-level variation and overlooks structural causes of inequality. Status characteristics theory posits how socially recognized traits, such as gender, contribute to the formation of informal hierarchies by denoting perceived levels of competence to group members. We investigated gender as a status characteristic in groups in space analog environments. We used data from the Mars Desert Research Station (MDRS) and hypothesized that women crew members are less likely than men to be selected to participate in simulated extravehicular activities during a Mars simulation at the MDRS. We used reports and …

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 …

Coping During Conventional Submarine Missions: Evidence Of A Third Quarter Phenomenon?, Charles H. Van Wijk Dec 2018

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 …
