We conducted a field study of 71 action teams to examine the relationship between team mental model similarity and accuracy and the performance of real-world teams. We used Pathfinder to operationalize team members’ taskwork mental models (describing team procedures, tasks, and equipment) and teamwork mental models (describing team interaction processes) and examined team performance as evaluat...

INTRODUCTION Mental exertion is a psychophysiological state caused by sustained and prolonged cognitive activity. The understanding of the possible effects of acute mental exertion on physical performance, and their physiological and psychological responses are of great importance for the performance of different occupations, such as military, construction workers, athletes (professional or rec...

Classic findings from the neuropsychological literature invariably indicated that performances on tests of memory that can be accomplished without conscious awareness were largely spared in amnesia, while those that required conscious retrieval (e.g., via recognition or recall) of information learned in the very same sessions was devastatingly impaired. Based on reports of such dissociations, i...

This study sought to examine the effect of helmet weight on cognitive performance and mental workload. Twenty participants were studied in three one-hour sessions. The participants were asked to read and work with computer under three conditions: while wearing no helmets, while wearing a helmet that weighed 800 g (A), and while wearing a helmet weighing 1500 g (B). “N-back” task and Continuous ...

Many tasks in the real world require simultaneous processing of mental information alongside physical activity. Whilst physical workload may have an impact on mental performance and attentional resources, most previous studies in ergonomics have not systematically investigated the impact of interactions between physical and mental demand on individual performance. The purpose of this study was ...

purpose some major competitions (e.g. london olympics, 2012) are scheduled during the ramadan fasting month. little attention has been given to explore the archers’ performance related subjective experiences with a qualitative method. therefore, this study addressed individual archers’ subjective experiences within the framework of self-regulation during ramadan. methods eleven elite malaysian ...
