Book excerpt: Effort to improve work methods employed in the Army's monitor systems is critical to the assessment of human performance within the system and to the determination of system reliability. The present study reports on one segment of the research effort--improvement of work methods employed in producing a transcript. Three work methods, differing in the number of transcribers contributing to the final product, were compared with respect to accuracy and completeness of the resulting transcription. These methods (involving one, two or three transcribers) were tested under three levels of noise which yielded high, medium, and low intelligibility under standard conditions. Data obtained were interpreted by analysis of variance technique. A small but consistent difference in favor of multiple transcriber work methods was found to exist. Differences were statistically significant only at the medium noise level. A secondary finding of potential value was that repeated exposures to a message resulted in some increase in accuracy at low and medium noise levels; repeated exposures at the high noise level were conductive to error.
