A survey conducted by the U.S. Army Research Institute (ARI) in Fiscal Year 1979 identified the number and types of aviation warrant officers (AWOs) who were leaving the Army and the factors that influenced the AWOs' decisions to leave. Despite an increase in retention of AWOs since the survey was conducted, the need for continuing concern about AWO-retention exists. ARI currently is developing a separation questionnaire that will be administered ...
Eight experienced US Army aviators performed various maneuvers in an instrumented helicopter to test the relative usability of two bifocally configured night vision goggles. Both configurations were statistically better than the unmodified arrangement when looking at a pilot's ability to hold a precise altitude at night. The subjective data, supported by flight performance observed betweeen the two bifocals, further suggested that a 24% bifocal version was more desirable than a ...
The study of one's ability to maintain attention over a prolonged period of time has been of particular interest since increased technology has reduced man's role in many systems to that of a monitor. In many industrial and military situation, man's physical activities have been reduced while attentional demands have been reduced while attentional demands have been increased. Radar and sonar monitors, during World War II, were some of the ...
Habituation has been defined as a response decrement produced by repeated or continuous stimulation (Harris 1943). Cain and Carlson (1971) have demonstrated that a response induced by electrical brain stimulation (EBS) can habituate. Carlton (1963) suggested that the physiological basis of habituation was accumulation of acetylcholine at central cholenergic synapses and that the effects of this accumulation could be blocked by anticholenergic drugs such as scopolamine. The present experiment was ...
