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 …

Impact Of Tropical Climate On Selective Attention And Affect, Guillaume R. Coudevylle, Maria Popa-Roch, Stéphane Sinnapah, Olivier Hue, Nicolas Robin Jul 2018

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. …

Employing A User-Centered Design Process For Cybersecurity Awareness In The Power Grid, Jean C. Scholtz, Lyndsey Franklin, Aditya Ashok, Katya Leblanc, Christopher Bonebrake, Eric Andersen, Michael Cassiadoro Jan 2018

Employing A User-Centered Design Process For Cybersecurity Awareness In The Power Grid, Jean C. Scholtz, Lyndsey Franklin, Aditya Ashok, Katya Leblanc, Christopher Bonebrake, Eric Andersen, Michael Cassiadoro

Journal of Human Performance in Extreme Environments

In this paper, we discuss the process we are using in the design and implementation of a tool to improve the situation awareness of cyberattacks in the power grid. We provide details of the steps we have taken to date and describe the steps that still need to be accomplished. The focus of this work is to provide situation awareness of the power grid to staff from different, non-overlapping roles in an electrical transmission organization in order to facilitate an understanding of a possible occurrence of a cyberattack. Our approach follows a user-centered design process and includes determining the types …

Incorporating Human Readiness Levels At Sandia National Laboratories, Judi E. See, Jason Morris, Richard Craft, Michael Moulton, Steven M. Trujillo Jan 2018

Incorporating Human Readiness Levels At Sandia National Laboratories, Judi E. See, Jason Morris, Richard Craft, Michael Moulton, Steven M. Trujillo

Journal of Human Performance in Extreme Environments

Since 2010, the concept of human readiness levels has been under development as a possible supplement to the existing technology readiness level (TRL) scale. The intent is to provide a mechanism to address safety and performance risks associated with the human component in a system that parallels the TRL structure already familiar to the systems engineering community. Sandia National Laboratories in Albuquerque, New Mexico, initiated a study in 2015 to evaluate options to incorporate human readiness planning for Sandia processes and products. The study team has collected the majority of baseline assessment data and has conducted interviews to understand staff …

Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña Jan 2018

Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña

Journal of Human Performance in Extreme Environments

Exposure to extreme environments is both mentally and physically taxing, leading to suboptimal performance and even life-threatening emergencies. Physiological and cognitive monitoring could provide the earliest indicator of performance decline and inform appropriate therapeutic intervention, yet little research has explored the relationship between these markers in strenuous settings. The Rim-to-Rim Wearables at the Canyon for Health (R2RWATCH) study is a research project at Sandia National Laboratories funded by the Defense Threat Reduction Agency to identify which physiological and cognitive phenomena collected by non-invasive wearable devices are the most related to performance in extreme environments. In a pilot study, data were …
