The Effects of One Night's Loss of Sleep and Recovery on Physiological, Performance, and Subjective Indices ( )
1 edition published in 1994 in English and held by 1 WorldCat member library worldwide
The effects of one night's sleep loss were tested on subjects who were tested again after a night's recovery sleep. Several physiological measures were taken while subjects were administered the AGARD SIRES Battery (to assess performance changes) and the NASA-ThX (a subjective index). In general, all measures showed changes with sleep loss which then recovered with one nighfs sleep. On several of the SIRES Battery tasks, reaction times increased and accuracy decreased after a night without sleep, and then recovered with a night's sleep. Tracking performance especially was consistently affected. Blink rate reliably increased with a night's sleep loss, and recovered with sleep; blink duration tended to increase with sleep loss. Heart rate decreased with sleep loss, while heart rate variability at high and medium bands was found to increase consistently. Power in the EEG alpha band tended to be greater after a night's loss of sleep when it was measured in terms of absolute power and as relative to total EEG power. Evoked potential results were equivocal. Subjectively, subjects ranked the individual SIRES Battery tasks as harder after a night without sleep. Just one night without sleep affected task performance, physiological measures, and subjective assessments of task requirements; recovery generally occurred with one night of sleep

Psychometric Correlates of the Effects of Image-Enhancing Algorithms on Visual Performance ( )
1 edition published in 2006 in English and held by 1 WorldCat member library worldwide
Future military image acquiring devices will have computational capabilities that will allow agile, realtime image enhancement. In preparing for such devices, numerous image enhancement algorithms should be studied; however, these algorithms need evaluating in terms of human visual performance using military-relevant imagery. Evaluating these algorithms through objective performance measures requires extensive time and resources. We investigated subjective methods for down-selecting algorithms to be studied in future research, and thus, provide a methodology for down-selection, Imagery was processed using six algorithms and then ranked along with two baselines through the method of paired comparisons and the method of magnitude estimation, in terms of subjective attitude. These rankings were then compared to objective performance measures: reaction times and errors in finding targets in the processed imagery. In general, we found associations between subjective and objective measures. This leads us to believe that subjective assessment may provide an easy and fast way for down-selecting algorithms but at the same time should not be used in place of objective performance-based measures
Putting the Science Back in C2: What Do the Buzzwords Really Mean? ( )
1 edition published in 2007 in English and held by 1 WorldCat member library worldwide
Current command and control "C2" terminology is laden with buzzwords that may, or may not, be useful to helping advance the science of C2 "e.g., effects-based operations "EBO" or sensemaking". In theory each term was devised for a reason, however, more often than not the reasons are lost and the terms are bantered about as "proof" of a good system, experiment, etc. We review some of the major terms and their history, as well as the potential evidence for their scientific integrity. Next we discuss how best to understand these terms by investigating their psychological "e.g., cognitive and social" as well as decision making roots. Finally we show how one may develop experiments and then eventually systems that either test or use these terms as they were originally defined. We give examples of how we are attempting to test these ideas in the laboratory as well as how others may test them in the future. We conclude with some discussion about the usefulness of buzzwords in the C2 realm as well as ways to keep them effective exemplars of their original meanings thus helping to advance the theory as well as knowledge of C2 systems
