Abstract:

The Monitor Performance Task has as an ongoing objective the accomplishment of research to meet a requirement of the U. S. Army Security Agency for improvement of work methods in several critical human factors areas in the Armys monitor system. The present publication reports on one segment of this research effort which deals with voice radio messages embedded in atmospheric noise. The study was conducted to explore the question of whether individuals show consistent differences in accuracy of transcription and whether any such differences are predictable by conventional measures. Voice-radio transcriber performance under low, medium, and high levels of atmospheric noise is analyzed. Prediction of performance by Army Classification Battery tests and effect of introduction of errors into transcript are examined. Pronounced individual differences in transcription were found, but differences were stable over time and across a broad range of noise intensity. Findings suggest the practicality of the use of a job sample performance measure and standardized sets of noise-masked messages as an approach to the selection problem. Author
