Abstract:

Three experiments investigated how individuals learn to classify sequentially-structured patterns of complex environmental sounds. In Experiment 1 listeners classified either auditory patterns or their visually-presented symbolic analogues as targets or nontargets. Some individuals received observation trials on which they simply heard saw examples of the target patterns prior to classification. The observation trials were shown to be effective for target acquisition, and positive transfer occurred between symbolic observation and subsequent auditory pattern classification. The results of Experiments 2 and 3 suggested further that a relatively direct structural similarity must exist between the observed and classified target patterns for the observations to be effective. When this relation was subtle or abstract, positive transfer was limited. Post experimental tests in Experiments 1 and 3 also suggested that individual had learned something about the composition rules used to produce the target patterns rather than simple paired-associate responses. These findings have implications for pattern classification theory and for the design of performance aids for sonar technicians. Author
