Perceived Motion Sickness And Effects On Shooting Performance Following Combat Vehicle Transportation, Joakim Dahlman, Torbjörn Falkmer, Staffan Nählinder
Journal of Human Performance in Extreme Environments
This study used a quasi-experimental, repeated measures design to study the relationship between targeting performance and perceived motion sickness following exposure to motion in a land-based transportation setting. The targeting performances of 22 basic training conscript soldiers were examined after repeatedly being transported in the vehicle. Soldiers also rated their perceived motion sickness according to subjective scales before and after the two exposures to transportation. Results showed that perceived motion sickness was correlated to perceived decrease in targeting performance, due to factors labelled as “Combined subjective symptoms”. The study supports the idea that motion sickness and its effect on performance …
Factors Influencing Physical Risk Taking In Rock Climbing, Marcus K. Taylor, Daniel R. Gould, Lew Hardy, Tim Woodman
Factors Influencing Physical Risk Taking In Rock Climbing, Marcus K. Taylor, Daniel R. Gould, Lew Hardy, Tim Woodman
Journal of Human Performance in Extreme Environments
This study was designed to investigate factors influencing physical risk taking in the sport of rock climbing. Specifically, the relationships between physical risk taking, sensation seeking, spheres of control, and desirability of control were examined. One hundred five rock climbers from the United States completed a series of surveys measuring each of the above-mentioned psychological variables. As predicted, physical risk taking demonstrated significant positive relationships to both total sensation seeking and thrill/adventure seeking (TAS). The expected relationships between physical risk taking, personal control and desirability of control were not supported. As hypothesized, no substantive patterns were revealed between physical risk …
Motivation In Extreme Environments: A Case Study Of Polar Explorer Pen, Juliette C. Lloyd, Michael J. Apter
Motivation In Extreme Environments: A Case Study Of Polar Explorer Pen, Juliette C. Lloyd, Michael J. Apter
Journal of Human Performance in Extreme Environments
This study documents the motives of a polar explorer, Pen Hadow, during the period of a 64-day solo expedition in which he skied, without resupply by aircraft, from Canada to the North Geographic Pole. The framework of reversal theory (Apter, 1982) was used to provide a systematic and comprehensive structure for studying such motivation in an extreme environment. Quantitative data were obtained by using the Apter Record of Motivational States. Qualitative data came from interviews structured in terms of reversal theory. The main result was that the explorer needed at different times to call upon all the eight motivational states …
