Sonar Recognition Training: An Investigation of Whole VS. Part and Analytic VS. Synthetic Procedures.
Annett, John
An experienced person, in such tasks as sonar detection and recognition, has a considerable superiority over a machine recognition system in auditory pattern recognition. However, people require extensive exposure to auditory patterns before achieving a high level of performance. In an attempt to discover a method of training people to recognize auditory patterns in an expeditious fashion, fifteen methods of teaching identification of complex sonar-like sounds were compared. These included whole and part methods in which subjects were trained on samples of whole sounds, received pre-training on components of the sounds, or were exposed to components in the context of whole sounds. The conditions included variations in the order in which training items were presented and in the kinds of verbal instruction given. Overall, the various part methods were not superior to training on whole sound items. The best of the part methods drew attention to only one feature of the whole sound. Some systematic orders of presentation showed no advantage over random order presentation. Verbal instruction drawing attention to cues and their value in classification did not prove effective. Among the various combinations of training procedures and state-of-the-art training techniques, the critical ingredient seems to be amount of exposure to instances of the recognition classes to be learned.
