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.

Download or read book Transcriber Confidence in Relation to Accuracy of Transcription written by Eugene P. Stichman and published by . This book was released on 1966 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measures of two aspects of performance--message intelligibility and expressed confidence in the correctness of transcription--were obtained from 8 Army enlisted men (untrained in communications) transcribing word lists received at 3 signal-to-noise ratios. Confidence was expressed through the use of a five-point rating scale ranging from 'fully confident' to 'not at all confident', and a separate rating was assigned to each word in a list as it was transcribed. A significant relationship was obtained between transcriber confidence and accuracy of transcription. As expected, both mean intelligibility and mean confidence ratings increased as a direct function of signal-to-noise ratio. Signal-to-noise ratio did not similarly affect the relationship between confidence and accuracy. Because of generally unpredictable and unstable listening conditions in the field, the relationship between confidence and accuracy--averaged across signal-to-noise ratios--appears to provide a stable measure which is the best practical basis for estimating transcript accuracy. Conclusion was that a positive relationship exists between transcriber confidence of correct reception and message intelligibility, even when personnel untrained in communications serve as transcribers. While far from perfect, the relationship is sufficient to warrant further research using trained communications transcribers. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The actual and potential contributions of human factors to the smooth and efficient functioning of systems for the ground control of aircraft are described and discussed. These systems are concerned with air traffic control or air defense, which fulfill different roles but share many human factors problems. The nature of the human factors contribution at each stage in the evolution of a ground control system is described. Much work has dealt with displays, controls, or communications, or with man's role in complex man-machine systems. Individual differences are considered in relation to selection, training, and screening procedures, and some of the differences which appear most relevant in systems are discussed. Both traditional and new methods for measuring operators are examined in terms of their merits and limitations. The factors of potential relevance to task performance are very numerous, and certain advances in other applied or academic contexts may be adapted with profit to ground control systems. Many of the proposed solutions to human factors problems have been based on limited evidence, mainly because man is treated primarily as a system component. Numerous studies have produced findings related to a specific task, but few widely applicable facts have emerged. Some probable future trends in the application of human factors to ground control systems are suggested. (Author).

This book was released on 1967 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study sought to determine whether operational communications personnel can rate their performance in transcribing voice radio messages partially embedded in noise with sufficient precision for the ratings to have potential operational utility. Eight experienced communications operators rated their confidence in the accuracy of their reception and transcription of messages received at three signal-to-noise ratios ( -6 db, 0 db, +6 db), using a five-point rating scale. As a control, subjects also received and transcribed the messages without making ratings. Measures of transcript accuracy and expressed confidence in transcription were compared with results from a prior study in which subjects had no formal training or experience in communications or transcription. Experienced operators were highly successful in judging their own accuracy, the relationship between confidence and accuracy being r sub tet = .78. Some overconfidence at the upper end of the rating scale and underconfidence at the lower end were evident. Intelligibility improved from 20% to 88% as signal-to-noise ratio increased. The communications operators performed better than the non-communications trained subjects in the former study both in accuracy of transcription and in precision of confidence ratings. Judging the transcription did not affect the average accuracy of the transcripts in either study. In both studies, subjects tended to make effective use of less than all five points of the confidence rating scale. (Author).
