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.

Available in PDF, EPUB and Kindle. Book excerpt: Studies are conducted by the Combat Communications Task in voice-radio communications techniques and overall performance of personnel involved in communications operations. An experiment was designed to determine the effects of 20 different transcription methods on the performance of 12 Army enlisted men in transcribing word lists received at 4 signal-to-noise levels. Three aspects of communications procedure were examined: listening to the message, writing the message as it was heard, and using a previous transcript of the message as an aid in re-listening and re-transcribing. Significant improvement in performance was obtained when subjects both listened to and wrote the word lists more than once. Performance did not improve at any signal-to-noise ratio when listening to a given word list more than once before writing the transcript nor when the subjects used a first or second transcript as a reference aid in retransribing a word list. Conclusion was that although the actual obsolute gain in accuracy was low, there was sufficient improvement to warrant repeated listening and repeated writing of messages when reception conditions are below the marginal level of channel communications.
