The selection, development, and operation of several tasks for use in skilled-operator-performance research are described. The tasks are intended, collectively, to sample a broad spectrum of abilities required by complex operator systems; individually they vary to the extent with which demands are placed upon attentional, sensory input, decision, and motor processes. A tracking and monitoring task simulates some of the functions associated with pilot skill, while a radar ATC task simulates the en route controller's functions. Other tasks (auditory vigilance, problem solving, mental arithmetic, and choice reaction time) are of a more abstract nature.
This study concerned the rate of presentation of stimuli on a task involving the monitoring of a static process of the kind represented by aircraft wa...
Nineteen subjects were tested on two successive days on a complex performance device designed to measure functions of relevance to aircrew performance...
